Transcript

  • 1. OpenNMS Introduction
  • 2. AGENDA • What is OpenNMS • How to install OpenNMS • Discovery & Monitor Process • GUI Introduction
  • 3. What is OpenNMS • world’s first enterprise grade network management application platform developed under the open source model – World’s First : • From 1999/7 – Enterprise Grade : • monitor tens of thousands to ultimately unlimited devices – Application Platform • Design for “out of box” and highly customizable – Open Source • Under version 3 of the GNU General Public License (GPL)
  • 4. What is OpenNMS • Supported OS – LinuxUnix (rpm, apt), Windows, Mac OS • Programming Language – – – – Java, JSP jRobin (RRD tool for Java)  Graph Jasper  Reports OSGi, SVG, Vaadin and D3.js  Topology Map • Commercial License – GPLv3
  • 5. How to install OpenNMS • JDK (Java SE) – http://www.oracle.com/technetwork/java/javase/downloa ds/jdk7u9-downloads-1859576.html • PostgreSQL – http://www.postgresql.org/download/windows/ – Not install the newest version • OpenNMS – – – – http://sourceforge.net/projects/opennms/files/OpenNMS/ standalone-'opennms-installer-X.X.X.zip Run “%OPENNMS_HOME%binopennms.bat start” http://localhost:8980/opennms
  • 6. Discovery Process Device Scan supported protocol ping Discovery Daemon Wait 1 day to discovery Send event Capability Daemon
  • 7. Discovery Process • Discovery Daemon – Use “Ping” to find all device • Re-discovery every 24hr – /etc/discovery-configuration.xml • capsd (Capability Daemon) – Check all service in a device – etc/ capsd-configuration.xml • Supported services : HTTP, SNMP, ICMP, FTP, … – newSuspect event ( send-event.pl ) • Received this event to scan this IP • Received trap will call this event to scan device
  • 8. Monitor Process  Collected : data collection (/etc/connectd-configuration.xml) – Collect the data from device – /etc/connectd-configuration.xml – SNMP, WMI , OpenNMS-JVM, (NSClient, JMX, HTTP) • SNMPCollector – /etc/snmp-config.xml : community string – /etc/datacollection-config.xml, /datacollection : Supported SNMP MIB • Monitor : polling daemon – Every 5 minute to check service is responding correctly – etc/poller-configuration.xml) – Supported Service (xxxMonitor) • ICMP, DNS, SMTP, FTP, SNMP, HTTP, HTTP-8080, HTTP-8000, HTTPS, HypericAgent, HypericHQ, MySQL, SQL Server, Oracle, Postgres, SSH, IMAP, POP3, NRPE, NRPE-NoSSL, Windows-Task-Scheduler, OpenNMSJVM
  • 9. GUI introduction • • • • • • • • Home Node List Search Outages Path Outages Dashboard Events Alarms • • • • • • • Notifications Assets Reports Charts Surveillance Maps Admin
  • 10. Home • Node with Outages • Quick Search • Available Over the Past 24 Hours – /etc/categories.xml – Outages (SurveillanceStatus.java) • Green : 0 services down • Yellow : 1 service down • Red : more than 1 service down • Notification • Resource Graphs • KSC Reports (Key SNMP Customized)
  • 11. Node List • Info Table – – – – – – – Asset Information SNMP Attribute Path Outages Availability Node Interface General Surveillance Category Memberships – Notification – Recent Events – Recent Outages • Link – – – – – – – – – View Events View Alarms View Outages Asset Info HTTP Resource Graphs Rescan Admin Schedule Outage • poll-outages.xml – View in Geographical Map
  • 12. Node List • StrafePing – stores the ICMP response-time of each as well as the packet loss – poller-configuration.xml • <include-range begin="192.168.6.130" end="192.168.6.140"/>
  • 13. Search • Search for Nodes – Name containing – TCP/IP Address like • 192.168.*.* • 192.168.0-255.0-255 • 192.168.0,1,2,3-255.* – – – – ifAlias, ifName, ifDescr + contains, equals Providing service MAC Address like Foreign Source name like • Search Asset Information – Category – Field – Containing Text
  • 14. Outages • Current Outages • All Outages • Additional Query Symbol – - :show the data not matched the selected field – +:show the data matched the selected field – >:show items beginning before this one – <:show items beginning after this one
  • 15. Path Outage • Setting the child device below the parent device • Admin/Configure Notifications/Configure Path Outages – Define the Critical Path • 10.1.3.254 – Current Rule • IPADDR IPLIKE 10.1.3.1-3
  • 16. Dashboard • • • • Surveillance View: default Alarms Notifications Node Status – Add to Surveillance • Resource Graph
  • 17. Events • Events Type – outstanding – acknowledged • Advanced Search – – – – – – – – Event Text Contains TCP/IP Address Like Node Label Contains Severity Service Events After/Before Sort By Number of Events Per Page
  • 18. Alarms • More important Events – The same events will correlate to one alarms – /etc/eventconf.xml • <alarm-data reduction-key="%nodeid%" alarmtype="1" /> – reduction-key : reduce rules • NCS Alarm List – Network Communication Services – Supported by Juniper company (JunosSpace)
  • 19. Notifications • Your outstanding notices • All outstanding notices • All acknowledge notices • Setting the Notification 1. 2. 3. 4. Create user Destination Paths Event Notifications Configure Mail • etc/javamail-configuration.properties – – org.opennms.core.utils.fromAddress=FROM-EMAIL-ADDRESS org.opennms.core.utils.mailHost=MAIL-SERVER-IP
  • 20. Create Threshold • /etc/threshd-configuration.xml – Define name, IP range, service • /etc/threshold.xml – Thresholds type : high, low, absolute change, relative change – Example • <threshold type="high" ds-type="node" value="80.0" rearm="50.0" trigger="3" ds-label="" filterOperator="or" ds-name="avgBusy5“>
  • 21. Assets • All nodes with asset info
  • 22. Reports • Resource Graphs • KSC Performance, Nodes, Domains 1. Create “Customized Report” 2. Add the “Resource Graph” to the report • Database Reports – Database Reports – Performance Reports • Statistic Reports – Top 20 ifInOctets across all nodes – Weekly Top 10 response across all nodes
  • 23. Charts
  • 24. Surveillance • Use the Matrix to show the important device Production Test Development – Admin/Manage Surveillance Categories Routers Switches Servers

  • 26. Linkd • layer 2/3 iso/osi model network topology discovery daemon – Bridge Forwarding Table, Spanning Tree Information and IP Net To Media Table – IP Routes (Layer 3) – Cisco Discovery Protocol – Link Layer Discovery Protocol – OSPF (Layer 3) • /etc/linkd-configuration.xml – Collect SNMP data from node – Discovery network topology
  • 27. SVG Map • Map -> Admin Mode – Map  Open, New, Save, Close, Clear, Background – Node  Add, Add Range, Add Category, Add Range, Add Neighs, Add with Neighs, Add Map – Reload  Maps, Nodes, Config • The maps Configuration File – /etc/map.properties • severity, status, icon, availability visualization properties and parameters for map elements • Changing map Style – Customize Tooltip, Context Menu, Menu, etc.. – /map/svgjavascript/ApplicationVariables
  • 28. Topology Map • Display Linkd and VMWare network topology – OSGi, SVG, Vaadin and D3.js
  • 29. Admin • OpenNMS System – – – Configure Users, Groups and On-Call Roles System Information Instrumentation Log Reader • • The Collecter log status Operations – – – Configure Discovery Configure SNMP Community Names by IP Configure SNMP Data Collection per Interface • – – – – – – – Manage and Un-manage Interfaces and Services Manage Thresholds Send Events Configure Notifications Scheduled Outages SNMP MIB Compile : Generate Event & Data Collection Manage Events Configuration • – collect this interface or not etc/events/xxx.events.xml Manage SNMP Collections and Data Collection Groups • etc/datacollection/xxx.xml
