Dieser Vortrag gibt einen Überblick über die neuen Features von OpenNMS 14. Es gibt eine neue Topologie der Benutzeroberfläche, um sich durch das Netzwerk zu navigieren. Für NOCs wurde eine neue Funktion hinzugefügt, um Informationen am Wallboard und der Bedienoberfläche anzuzeigen. Es wurde ebenfalls eine neue Methode entwickelt, um Zeitreihendaten in Cassandra-basierten Zeitreihendatenbanken, genannt NewTS, zu speichern.

4. OpenNMS is the world's first
enterprise-grade network
management application
platform developed under the
open source model.

5. “world's first”
•NetSaint 2000-01-10 1323
•OpenNMS 2000-03-29 4141

•Icinga 2009-04-21

6. “enterprise-grade”
• Nearly 63,000 Devices on a One Instance (Swisscom)
• 1.2 Million Data Points Every Five Minutes (New Edge)
• 320,000 Interfaces per Device (Wind)
• 2000 events/sec (SRNS)
• 4000 Remote Monitors (Papa Johns)

7. “network management application platform”
The Architecture of OpenNMS has been
designed to allow for easy integration of
other tools, both proprietary and open.

8. “open source model”
OpenNMS is published under the AGPLv3
and all components are licensed under an
OSI-qualified free software license.

10. •Event Management: including custom events, SNMP traps,
syslog, event translation, automations and correlation.
•Provisioning: Both automated and directed discovery. Fully
supported via ReST.
•Performance Data Collection: SNMP, HTTP, XML, JDBC,
JMX, WMI
•Service Assurance: Service Checks with Outage Models
The Four Main Areas of OpenNMS

18. Ops Panel and Wall Board

19. Alarms and Automations
• Alarms exist to
– Reduce similar events
– Perform correlation
• Automations consist of
– Trigger (optional)
– Action
– Event (optional)
• Automations operate mainly on alarms but can access
the whole database
• Used for correlation

20. Automations Example: Did a script run?
External Script
Script Started
Script Finished
Script Error
Port 5817
O
p
e
n
N
M
S

21. Step 1: Create a Tracker Alarm
• Trigger: See if a ScriptFinished alarms exists without a
tracker alarm
• Action: NOP
• Event: Create a new event that will generate the
tracker alarm
<automation name="generateTracker" interval="30000" active="true"
trigger-name="selectFinishedScriptsNoTracker"
action-name="doNothingAction"
action-event="createTrackerAlarm" />

22. selectFinishedScriptsNoTracker
<trigger name="selectFinishedScriptsNoTracker"
operator="&gt;=" row-count="1" >
<statement>
SELECT alarmid AS _alarmid,
nodeid AS _nodeid,
eventuei AS _eventuei,
lasteventtime AS _ts,
substring(eventparms from '.*name=(w+).*') AS _parmname
FROM alarms
WHERE eventuei='uei.opennms.org/scripts/scriptFinished'
AND substring(reductionkey from
'uei.opennms.org/scripts/scriptFinished:(.*)') NOT IN
(SELECT substring(reductionkey from '.*scriptTracker:.*:(.*)')
FROM alarms

23. doNothingAction
<action name="doNothingAction" >
<statement>
UPDATE node
SET nodeid = -1
WHERE nodeid = -1
</statement>
</action>

24. createTrackerAlarm
<action-event name="createTrackerAlarm" for-each-result="true" >
<assignment type="field" name="uei"
value="uei.opennms.org/scripts/scriptTracker" />
<assignment type="field" name="nodeid" value="${_nodeid}" />
<assignment type="parameter" name="name" value="${_parmname}" />
<assignment type="parameter" name="alarmId" value="${_alarmid}" />
<assignment type="parameter" name="alarmEventUei" value="${_eventUei}" />
</action-event>

25. Step 2: Create a Tracker Alarm
• Trigger: See if a new ScriptFinished has arrived
• Action: Update the last event time for the Tracker
• Event: none
<automation name="updateTracker" interval="30000" active="true"
trigger-name="selectFinishedScripts"
action-name="updateTrackerAlarms" />

26. selectFinishedScripts
<trigger name="selectFinishedScripts" operator="&gt;=" row-
count="1" >
<statement>
SELECT alarmid AS _alarmid,
nodeid AS _nodeid,
lasteventtime AS _lasteventtime,
substring(eventparms from '.*name=(w+).*') AS _parmname,
now() AS _ts
FROM alarms
WHERE eventuei='uei.opennms.org/scripts/scriptFinished'
</statement>
</trigger>

27. updateTrackerAlarms
<action name="updateTrackerAlarms" >
<statement>
UPDATE alarms
SET firstautomationtime =
COALESCE(firstautomationtime, ${_ts}),
lastautomationtime = ${_ts},
lasteventtime = ${_lasteventtime}
WHERE eventuei = 'uei.opennms.org/scripts/scriptTracker'
AND substring(reductionkey from
'uei.opennms.org/scripts/scriptTracker:(.*)')
= ${_nodeid}||':'||${_parmname}
</statement>

28. Step 3: See if the Tracker Alarm is
Updated
• Trigger: Select all of the open Tracker alarms and
check if they have been updated.
• Action: NOP
• Event: Create a new event that will generate the
“script did not run” alarm
<automation name="generateScriptDidNotRun" interval="30000" active="true"
trigger-name="selectTrackerAlarms"
action-name="doNothingAction"
action-event="createScriptDidNotRunAlarm" />

29. selectTrackerAlarms
<trigger name="selectTrackerAlarms" operator="&gt;=" row-count="1" >
<statement>
SELECT alarmid AS _alarmid,
nodeid AS _nodeid,
eventuei AS _eventuei,
lasteventtime AS _lasteventtime,
now() as _ts,
substring(eventparms from '.*name=(w+).*') AS _parmname
FROM alarms
WHERE eventuei='uei.opennms.org/scripts/scriptTracker'
AND lasteventtime &lt; now() - interval '3 minutes'
AND substring(reductionkey from 'uei.opennms.org/scripts/scriptTracker:(.*)')
NOT IN (select substring(reductionkey from '.*scriptNotRunning:(.*)')
FROM alarms WHERE eventuei='uei.opennms.org/scripts/scriptNotRunning')
</statement>
</trigger>

30. doNothingAction
<action name="doNothingAction" >
<statement>
UPDATE node
SET nodeid = -1
WHERE nodeid = -1
</statement>
</action>

31. createScriptDidNotRun
<action-event name="createScriptDidNotRunAlarm" for-each-result="true" >
<assignment type="field" name="uei"
value="uei.opennms.org/scripts/scriptNotRunning" />
<assignment type="field" name="nodeid" value="${_nodeid}" />
<assignment type="parameter" name="name" value="${_parmname}" />
<assignment type="parameter" name="alarmId" value="${_alarmid}" />
<assignment type="parameter" name="alarmEventUei"
value="${_eventUei}" />
</action-event>
