A Probe-Fed Patch Antenna with a Step-Shaped Ground Plane for 2.4 GHz Access ...Saou-Wen Su
This Letter demonstrates a new design of a probe-fed patch antenna with a modified antenna ground, and a constructed prototype ideal for applications in a 2.4-GHz WLAN access point is presented. The antenna has a thick air substrate for broadband operation and is fed by an inclined probe pin at the edge of the patch bent portion. The antenna ground comprises different portions and is in the shape of a step. With the proposed probe feed and ground configuration, good impedance bandwidth with VSWR below 1.5 over the 2.4 GHz WLAN band can be obtained. In addition, good broadside radiation characteristics have also been observed.

The article discusses NBA player J.J. Barea, providing 5 facts about his basketball career and championships, including that one of his lungs was once filled with fluid and he lost 20 pounds from mononucleosis. It also shares 5 opinions on Barea's playing style and size. Additionally, it notes that Barea was once stuck on a tropical island with his girlfriend instead of going to work, and then discusses his past NBA season, though the recap became boring. The reviewer gives the article a 7 out of 10.
This document presents a method for improving social search by using an influence model to identify stronger paths between nodes in a social graph, rather than just shortest paths. The authors define influence as proportional to how much a node invests in another. They show that in Twitter and DBLP graphs, the strongest path is often longer but better than the shortest path. Over 40% of strongest paths in DBLP and 67% in Twitter were longer than the shortest path. Accounting for influence provides more effective social search than only considering path length.

You probably have questions on how this new licensing approach works and how to benefit from it. Most importantly, you likely have budget constraints and want to save money where possible. Don’t worry, we can help with all of this!
We’ll show you how to fix common misconfigurations that cause higher-than-expected user counts, and how to identify accounts which you can deactivate to save money. There are also frequent patterns that can cause unnecessary cost, like using a person document instead of a mail-in for shared mailboxes. We’ll provide examples and solutions for those as well. And naturally we’ll explain the new licensing model.
Join HCL Ambassador Marc Thomas in this webinar with a special guest appearance from Franz Walder. It will give you the tools and know-how to stay on top of what is going on with Domino licensing. You will be able lower your cost through an optimized configuration and keep it low going forward.

2. Introduction
monit is a utility for managing and monitoring, processes, files, directories
and devices on a Unix system. Monit conducts automatic maintenance and
repair and can execute meaningful causal actions in error situations. E.g.
monit can start a process if it does not run, restart a process if it does not
respond and stop a process if it uses to much resources. You may use monit
to monitor files, directories and devices for changes, such as timestamp
changes, checksum changes or size changes.
Monit is controlled via an easy to configure control file based on a free-
format, token-oriented syntax. Monit logs to syslog or to its own log file and
notifies you about error conditions via customisable alert messages. Monit
can perform various TCP/IP network checks, protocol checks and can utilize
SSL for such checks. Monit provides a HTTP(S) interface and you can use a
browser to access the monit server.
3. Installation instructions
1. Download the monit-x.y(.z).tar.gz package.
(x.y.z denotes version numbers, for instance; monit-4.1.tar.gz)
2. Installing monit:
$ tar zxvf monit-x.y.z.tar.gz
$ cd monit-x.y.z
$ ./configure (use ./configure –-help to view available options)
$ make && make install
3. By default monit is installed in /usr/local/bin/ and the monit.1 man-file in
/usr/local/man/man1/ you can change this default location by using the
--prefix option to ./configure.
4. What to monitor?
● You may use monit to monitor dæmon processes or similar programs running on
localhost. Monit is particular useful for monitoring dæmon processes, such as
those started at system boot time from /etc/init.d/. For instance mail servers,
print servers, database servers, application servers, http servers and sshd.
● You may also use monit to monitor files, directories and devices on localhost.
Monit can monitor these items for changes, such as timestamp changes,
checksum changes or size changes. This is also useful for security reasons; you
can monitor the md5 checksum of files that should not change.
● You may even use monit to monitor remote hosts. First and foremost monit is an
utility for monitoring and mending services on localhost, but if a service depends
on a remote service, e.g. a database server or an application server, it can be
useful to test the remote host as well.
5. How to monitor?
● monit is configured and controlled via a control file called monitrc. The default
location for this file is ~/.monitrc. If this file does not exist, monit will try
/etc/monitrc and finally ./monitrc. You may also specify the control file monit
should use via the -c command-line switch. For instance,
$ monit -c /usr/local/etc/monitrc
● Before monit is started the first time, you can test the control file for syntax errors:
$ monit -t
$ Control file syntax OK
If there was an error, monit will print an error message to the console, including the
line number in the control file from where the error was found. For instance (in this
case, a wrongly formatted email address):
$ monit: parse error 'hauktildeslash.com' at line 114
● The monit software package comes with a monitrc example file which you can look
at and use as a starting point when you write your first control file. There is also a
comprehensive example collection at: http://www.tildeslash.com/monit/examples.html
6. Starting and stopping
Once you have created a monit control file you can start monit from the
console, like so:
$ monit
You can change some configuration directives via command-line switches, but
for simplicity it is recommended that you put these in the control file.
If monit was configured to run in dæmon mode (strongly recommended) and
all goes well, it will now detach from the terminal and run as a dæmon
process. As a dæmon, monit runs in cycles; It monitors services, then goes to
sleep for a configured period, then wakes up and start monitoring again in an
endless loop until you choose to stop monit by this command:
$ monit quit
You may instead choose to start monit from init via /etc/inittab. If the
monit dæmon should stop due to an error, the init program will re-spawn a
new monit process. Init will also automatically start monit at machine boot
time. To learn more on how to set-up monit to run from init, read the monit man
file.
7. The monit control file
The control file consists of a series of service entries and global option statements
in a free-format, token-oriented syntax. Comments begin with a # and extend
through the end of the line. There are three kinds of tokens in the control file:
grammar keywords, numbers and strings. On a semantic level, the control file
consists of only two types of entries:
● Global set entries
A global set entry starts with the keyword set and the item to configure.
● One or more service entries
A service entry starts with the keyword check followed by the service type to
monitor. A service entry can contain different if-tests to be performed on the
service. Some if-tests are particular to a certain service type. For instance, a
md5 checksum test may only be used in a check file entry.
A process entry requires a path to the pid file1 for the program. A file, a directory
or a device entry requires the path to the item to monitor. All other statements are
optional.
__
1
A pid file is a file containing a program's process identification number (pid)
8. Global statements
The start of a monit control file may look like this:
(1) # Monit control file
(2)
(3) set daemon 120 # Poll in 2-minute intervals
(4) set logfile syslog facility LOG_daemon # Default facility is LOG_USER
(5) set mailserver mail.foo.bar # Default smtp server is localhost
(6) set alert sysadm@foo.bar # Alert system admin on any event
(7) set httpd port 2812 address localhost
(8) allow localhost
(9) allow admin:monit
Line 1 is a comment. In line 3, monit is setup to start in dæmon mode and check each service
in 2 minute cycles (value in seconds). In line 4, monit is told to log error and status messages
via the syslog dæmon. Monit needs a SMTP server to send alert messages, and in line 5 we
specify the SMTP server monit should use. Line 6 defines sysadm@foo.bar as recipient for
any type of event. Line 7 specify that monit should start its own built-in mini-httpd server and
bind the server to local host only. If you want the http server to be accessible from other
machines, simply omit the address to bind to. Line 8 defines access control to the httpd server;
Hosts allowed to connect to the http server should be listed with one or more allow host
statements.
The allow statement in line 9 is special, it specify a username:password pair used for
HTTP Basic Authentication - the Browser will pop-up an authentication box asking you to
submit a username and a password before you can access the monit server. By reading the
documentation you can also learn how you can configure the monit http server to use SSL.
9. Monitoring a process
(1) check process apache with pidfile "/usr/local/apache/logs/httpd.pid"
(2) start = “/etc/init.d/httpd start"
(3) stop = "/etc/init.d/httpd stop"
(4) if failed port 80 and protocol http
(5) and request "/cgi-bin/printenv" then restart
(6) if cpu usage is greater than 60 percent for 2 cycles then alert
(7) if cpu usage > 98% for 5 cycles then restart
(8) if 2 restarts within 3 cycles then timeout
(9) alert foo@bar.baz
Line 1 starts a process service entry. It contains the keyword check and a descriptive name for
the process to monitor, in this case apache. Monit also require the process pidfile to be
stated.
If you want monit to start, stop or restart the process you must submit a start and stop program.
Line 2-3 defines those programs for this process. In line 4 we ask monit to open a connection
to the apache server and request a document from the server. If this test should fail, monit will
restart the apache process.
In line 6-7 the process characteristics are tested and if one of the tests are true an action is
executed. In line 8 a timeout is set. The rationale for a timeout is that monit should not waste
time trying to start a service if it has problems running stable. Finally in line 9 monit is
requested to send alert messages to foo@bar.baz. Monit raise alerts if a service error occurs.
10. Monitoring files
The following example demonstrate how you can use monit to automatically restart apache if the
apache configuration file httpd.conf was changed:
(1) check file httpd.conf with path /usr/local/apache/conf/httpd.conf
(2) if changed checksum
(3) then exec "/usr/local/apache/bin/apachectl graceful"
In line 1 monit is setup to monitor the apache configuration file. A check file entry requires a
descriptive name for the entry and a full path to the file to monitor. In line 2 we test the md5
checksum for the configuration file and if the test fails, (because the content of the file was
changed) then in line 3 apache is restarted via an exec statement.
Here is another example where we test the size of the apache log file and conduct a log rotate if
the size grows above a specified size.
(1) check file access_log with path /var/log/access_log
(2) if size > 100 Mb
(3) then exec "/usr/sbin/logrotate -f rotate_apache_now"
Normally you will run logrotate at night from (e.g.) crond but if the log file suddenly should
grow very large it may be necessary to do an “emergency” rotate. Another option is simply to ask
monit to send an alert if the log file grows very large. In this case, simply replace the exec
statement with alert.
11. Monitoring directories
You can use monit to monitor directories for changes. In this example we test the standard sbin
directory. If content was added or removed from this directory we raise an alert. For the
argument sake, we assume a fairly static system where the content of sbin should not change.
Of course, monitoring /sbin like this, may not be appropriate for your system, but if you want to
test a directory on your system for changes this is the test to use:
(1) check directory sbin with path /sbin
(2) if changed timestamp then alert
(3) alert foo@bar.baz
In line 1 monit is setup to monitor the /sbin directory. A directory service entry requires a
descriptive name for the service and a full path to the directory to monitor. In line 2, the
directory's timestamp is tested and if it was changed, monit will raise an alert to the address
stated in line 3.
Here we turn the table and monitor a directory that should change. This directory is expected to
change its content on an hourly basis. If no files were added (or removed) from the directory
within an hour (from the time monit was started) then monit will send an alert to the address in
line 4. As soon as the condition will recover, monit will send execute consistency checking script
and send alert:
(1) check directory db_tmp with path /data/tmp
(2) if timestamp > 1 hour the alert
(3) else if recovered then exec "/check/my/db"
(4) alert foo@bar.baz
12. Monitoring a device
Here is an example where monit is used to monitor a CDROM station. Admittedly, it's not a very
practical example, but it is fun and involve moving parts.
(1) check device CDROM with path /dev/cdrom
(2) start "/bin/mount /dev/cdrom"
(3) stop "/bin/bash -c '/bin/umont /dev/cdrom; /usr/bin/eject;'"
In line 1, we ask monit to check the cdrom device /dev/cdrom. To automatically mount the
cdrom if it is not mounted, we add a start method in line 2, informing monit how this device
should be started. In line 3 we also add a stop method, specifying the commands for
unmounting the device and also ejecting the cdrom from its disk tray. From monit's web interface
you can now, for instance, push the start button to mount the cdrom and push the stop button to
umount and eject the cdrom.
A more practical example, after all, is to use this feature to monitor a hard disk and raise alerts if
the device is about to run out of available space or inodes, such as:
(1) check device disk1 with path /dev/hda1
(2) start = "/bin/mount /dev/hda1"
(3) stop = "/bin/umont /dev/hda1"
(4) if space usage > 90% then alert
(5) if space usage > 99% then stop
(6) if inode usage > 90% then alert
(7) if inode usage > 99% then stop
(8) alert foo@bar.baz
13. Remote host monitoring (1)
You can use monit to monitor and test services running on a remote host.
(1) check host rhn.redhat.com with address rhn.redhat.com
(2) if failed port 80 protocol http and request "/help/about.pxt"
(3) then alert with the mail-format {subject: RedHat is down again!}
(4) if failed port 443 type TCPSSL and protocol http
(5) with timeout 15 seconds then alert
(6) alert foo@bar.baz
(7)
(8) check host up2date with address 66.187.224.51 # This is ftp.redhat.com
(9) if failed port 21 protocol ftp
(10) then exec “/usr/bin/snpp -m
(11) 'Monit: $MONIT_EVENT for $MONIT_SERVICE' rladams”
The first entry monitors the remote host rhn.redhat.com on two ports; the standard HTTP and
HTTPS port numbers using the http protocol test. In line 4 we need to use a SSL socket type to
test a secure https server. The name after the host keyword is a descriptive name. You may use
any name here, in this example we simply use the same host name we will connect to.
The second entry monitors the remote ftp server ftp.redhat.com on the standard ftp port
number, i.e. port 21. If this test should fail, instead of sending an SMTP alert, as in the first entry,
we choose to execute an external program to handle the notification. (snpp is used to send a
text message to a Pager Terminal). $MONIT_EVENT and $MONIT_SERVICE (plus a few more)
are environment variables available to programs executed from within monit.
14. Remote host monitoring (2)
Monit also support a ping test you can use to check if a remote host is up:
(1) check host tildeslash.com with address tildeslash.com
(2) if failed icmp type echo with timeout 15 seconds then alert
(3) alert foo@bar.baz
In line 1 we define a remote host entry for the host tildeslash.com. In line 2 the ping test
is defined; monit is asked to send one icmp ping package and wait for up to 15 seconds for
a reply from the remote host. If the server did not reply within 15 seconds an alert is sent to
the email address stated in line 3. The timeout part of the icmp statement is optional and if
not used, timeout defaults to 5 seconds. If used, you can of course set the timeout to a
higher or to a lower value than 15 seconds.
The icmp test may only be used in a check host entry and monit must run with super user
privileges, that is, the root user must run monit. The reason is that the icmp test utilize a raw
socket to send the icmp package and only the super user is allowed to create a raw socket.
15. Protocol test (1)
When testing a connection, either at localhost or at a remote host, monit can test the server at
the protocol level. Monit support tests for many of the more popular protocols used on Internet
today, such as FTP, HTTP and SMTP (See the documentation for the complete list.). The
rationale for a protocol test is to test the server better, for instance some servers may allow you
to open a connection, but the server may be overloaded and cannot reply. This is typical for
(Java based) Application Servers, the server will accept a connection but the request processing
machinery itself has gone into a dead-lock and cannot process the request. A protocol test will
discover such problems.
Here are some connection-test examples where a protocol test is used:
(1) if failed port 80 protocol http then ...
(2) if failed port 25 protocol smtp then ...
The HTTP protocol test at line 1 will, if the connection succeed, request the default document
from the server. In HTTP terms that is;
GET / HTTP/1.1
Host: foo.bar.baz
Connection: close
If the server answers with an error code, such as; HTTP/1.1 500 Internal server error the
protocol test fails. The SMTP test is similar, if the mail server answers with the 220 status code
upon connection, all is well, otherwise the test fails. The other supported protocol tests are built
on the same principle.
16. Protocol test (2)
Although monit support quite a few protocols it supports far from all. This is one of the reasons
we also supply a general protocol test based on send and expect strings. This feature will allow
you to test, if not all then most of the text based protocols out there. Here is a simple example
for testing a HTTP server using send/expect strings instead of the built-in HTTP protocol test:
(1) check host tildeslash.com with address tildeslash.com
(2) if failed port 80
(3) send "GET / HTTP/1.0rnHost: tildeslash.comrnrn"
(4) expect "HTTP/[0-9.]{3} 200 .*rn"
(5) then ...
The test starting at line 2 opens a connection to the host tildeslash.com. If the connection
succeeded, monit sends the string in line 3 and in line 4 we define the string we expect the
server to return. If the server returns another string the test fails. Notice that you can use regular
expressions in the expect string. You can, of course also, use as many send/expect strings as
you want to. Here is another example for testing a SMTP server:
(1) if failed port 25
(2) expect "^220.*rn"
(3) send "HELO localhost.localdomainrn"
(4) expect "^250.*rn"
(5) send "QUITrn"
(6) expect "^221.*rn" ...
17. Available actions
From the previous examples you will notice that several different if-tests were used. Monit
provides a number of such tests, all on this common format:
IF <TEST> THEN ACTION
If the <TEST> should validate to true then the selected action is executed. Here are the available
actions you can choose from:
● alert sends the user an alert message.
● restart restarts the service and sends an alert. Restart is conducted by first calling the service's
registered stop method, wait for the service to stop and then call the service's start method.
● start starts the service and sends an alert.
● stop stops the service by calling the service's registered stop method and sends an alert. If
monit stops a service it will not be checked by monit anymore nor restarted again later. To
reactivate monitoring of the service again you must explicitly enable monitoring from monit's
web interface or from the console using the monitor argument.
● exec executes an arbitrary program and sends an alert.
● unmonitor will disable monitoring of the service and send an alert. The service will not be
checked by monit anymore nor restarted again later. To reactivate monitoring of the service
again you must explicitly enable monitoring from monit's web interface or from the console
using the monitor argument.
18. Security checks
For security reasons you may want to monitor files for changes and get a notification if a file was
tampered with (i.e. changed) and if it was recovered. The standard way to do this is to use the
check file statement and utilize a checksum test. You can also test the file's uid1, gid and
permissions.
(1) check file httpd with path /usr/local/apache/bin/httpd
(2) if failed checksum then alert
(3) if failed uid root then alert
(4) if failed gid root then alert
(5) if failed permission 750 then alert
(6) alert foo@bar.baz
Here we test the underlying apache binary used in the previous example. The checksum test in
line 2 will raise an alert if the binary was changed, to the address specified in line 6. (You must
always remember to specify an alert address in an entry if you want to receive an alert
message, either globaly by 'set alert ...' or localy per service as shown above). This is all fine
and dandy, but what if you are also using the same binary to start and stop a service from
monit? If the binary was changed then you probably do not want monit to start the program
using the changed binary if it was tampered with. The solution is to request monit, not to monitor
the process anymore and instead, send you a checksum alert. To do this you will need to setup
a depend link between the process entry and the check file entry. This is easy and in the next
slide we demonstrate how to do this.
1
The uid and gid refer to the owner and group id of the file, permissions are access restrictions for the file, in octal format. You may also use uid,
gid and permission tests in a directory or in a device entry.
19. Dependencies
Service1
Depends on
propagate
(1) check process apache
Actions
upward
(2) with pidfile "/usr/local/apache/logs/httpd.pid" Service2
(3) ...
(4) depends on httpd
(5) Service3
(6) check file httpd with path /usr/local/apache/bin/httpd
(7) if failed checksum then unmonitor
(8) alert foo@bar.baz
The first entry is the process entry for apache shown earlier (abbreviated for clarity). The fourth
line sets up a dependency between this entry and the service entry httpd in line 6. A depend tree
works as follows, if an action is conducted in a lower branch it will propagate upward in the tree
and for every dependent entry execute the same action.
In this case, if the checksum should fail in line 7 then an unmonitor action is executed and the
apache binary is not checked anymore. But since the apache process entry depends on the
httpd entry this entry will also execute the unmonitor action. In short, if the checksum test for the
httpd binary file should fail, both the check file httpd entry and the check process apache entry is
set in unmonitoring mode.
A dependency tree is a general construct and can be used between all types of service entries
and span many levels as shown in the illustration above and propagate any supported action.
20. Remote security check
It is possible to use monit to test the checksum for documents returned by a http server. This
feature is particularly useful if you provide software packages on a remote host and want to test
that a package is not changed, such as in this example where we test the monit package itself:
(1) check host tildeslash.com with address tildeslash.com
(2) if failed port 80 protocol http
(3) request "/monit/dist/monit-4.0.tar.gz"
(4) with checksum f9d26b8393736b5dfad837bb13780786
(5) then alert
(6) alert foo@bar
Monit will download and compute a checksum for the document (in the above case,
"/monit/dist/monit-4.0.tar.gz") and compare the computed checksum with the expected
checksum in line 4. If the sums does not match, then, in this case, an alert is sent to foo@bar
informing that the HTTP protocol test failed.
Note that monit will not test the checksum if the server does not set the HTTP Content-Length
header. A HTTP server should set this header when serving static documents (i.e. a file). A
HTTP server will often use chunked transfer encoding instead when dynamic content is served
(e.g. documents created by a CGI-script or a Servlet). Testing the checksum for dynamic
content is not very useful. There are no limitation on the document size, but keep in mind that
monit will use time to download the document over the network so it's probably smart not to ask
monit to compute a checksum for documents larger than 1Mb or so, depending on you network
connection of course.
21. Web-Interface
You can access the monit web
server via a Browser and
check the status of services
monitored.
You can also start, stop and
restart services from this
interface by clicking on a
service link. (e.g. apache)
