Elasticsearch, Logstash, Kibana. Cool search, analytics, data mining and more...Oleksiy Panchenko
In the age of information and big data, ability to quickly and easily find a needle in a haystack is extremely important. Elasticsearch is a distributed and scalable search engine which provides rich and flexible search capabilities. Social networks (Facebook, LinkedIn), media services (Netflix, SoundCloud), Q&A sites (StackOverflow, Quora, StackExchange) and even GitHub - they all find data for you using Elasticsearch. In conjunction with Logstash and Kibana, Elasticsearch becomes a powerful log engine which allows to process, store, analyze, search through and visualize your logs.

Analyze Virtual Machine Overhead Compared to Bare Metal with TracingScyllaDB
Running a virtual machine will obviously add some overhead over running on bare metal. This is expected. But there are some cases that the overhead is much higher than expected. This talk discusses using tracing to analyze this overhead from a Linux host running KVM. Ideally, the guest would also be running Linux to get a more detailed explanation of the events, but analysis can still be done when the guest is something else.
DTrace and SystemTap are dynamic tracing frameworks available for Solaris and Linux respectively. This session will give an overview of the static DTrace probes available in both Drizzle and MySQL and show numerous examples of scripts that utilize these probes. Mixing dynamic and static probes will also be discussed.
Brief introduction to DTrace technologies within OpenSolaris/Solaris 10 and DTrace probes within Apache, PHP and MySQL can provide end to end dynamic tracing of your Drupal based web site..

Monitoring as Code: Getting to Monitoring-Driven Development - DEV314 - re:In...Amazon Web Services
“Infrastructure as Code” has changed not only how we think about configuring infrastructure, but about the infrastructure itself. AWS has been at the core of this movement, enabling your infrastructure teams to benefit from software engineering best practices such as CI/CD, automated testing, and repeatable deployments. Now that you have mastered the art of managing your infrastructure as code, it’s time to leverage these same lessons for monitoring and metrics. In this session, we dive into how you can leverage tooling such as AWS, Terraform, and Datadog to programmatically define your monitoring so that you that you can scale your organizational observability along with your infrastructure, and attain consistency from local development all the way through production.

Performance Analysis: new tools and concepts from the cloudBrendan Gregg
Talk delivered at SCaLE10x, Los Angeles 2012.
Cloud Computing introduces new challenges for performance
analysis, for both customers and operators of the cloud. Apart from
monitoring a scaling environment, issues within a system can be
complicated when tenants are competing for the same resources, and are
invisible to each other. Other factors include rapidly changing
production code and wildly unpredictable traffic surges. For
performance analysis in the Joyent public cloud, we use a variety of
tools including Dynamic Tracing, which allows us to create custom
tools and metrics and to explore new concepts. In this presentation
I'll discuss a collection of these tools and the metrics that they
measure. While these are DTrace-based, the focus of the talk is on
which metrics are proving useful for analyzing real cloud issues.

2. strace
strace is a powerful debugging utility for Linux
and some other Unix-like systems to monitor
the system calls used by a program and all the
signals it receives.
3. ltrace
It intercepts and records the dynamic library
calls which are called by the executed process
and the signals which are received by that
process.
4. When you need visualised trending.
Let`s be honest, the raw data from sar, is just
not good enough for analyzing. Especially then
you need to present your finding to others.
● isag
● ksar
5. isag
● Basic GUI
● Has some security concerns
● Not included on RH / CentOS
7. Monitoring across the stack
It is much more common practice to separate
stack roles got between machines on all levels.
Such a practice is even more common since
the appearance and acceptance of
virtualization.
o monitor and troubleshoot your application you
need one place to monitor and relate
everything
8. Then you need complex correlations

● written in python / ruby
● Can re-use Nagios plugins
consider themselves to be “monitoring router”
basically it is a framework that:
connects “check” scripts run across many
nodes with “handler” scripts run on one or
more Sensu servers
16. logstash
logstash is a tool for managing your logs. It
helps you take logs and other event data from
your systems and move it into a central place.
logstash is open source and completely free.
http://logstash.net/
18. logstash sample: date
For example, syslog events usually have
timestamps like this:
"Apr 17 09:32:01"
match => [ "logdate", "MMM dd YYY HH:mm:
ss",
"MMM d YYY HH:mm:ss", "ISO8601" ]
20. graylog
Graylog2 is an open source log management
solution that stores your logs in ElasticSearch.
It consists of a server written in Java that
accepts your syslog messages via TCP, UDP
or AMQP and stores it in the database. The
second part is a web interface that allows you
to manage the log messages from your web
browser.
