SnmpresCritAppStatus

Path: /model/vendors/snmp_research/snmpres_crit_app_status.mod

This behavior model provides the status of the applications monitored by SNMP Research's CIAgent. When an application goes down and remains down for a specified time (the default is ten minutes), NerveCenter sends a 110031 Inform to the platform. When an application comes back up, the alarm returns to ground and sends a 120031 Inform to the platform. The nodes hosting the monitored applications must be associated with a property group that contains the property critAppProcEntry.

Property

The following property must be in the property group for the nodes hosting the applications you want to monitor:

critAppProcEntry

Trigger Generators

Below is a list of the objects that generate triggers:

• CritAppDown (mask or poll)
• CritAppUp (mask or poll)
• CritAppDownFast (poll)
• CritAppUpFast (poll)
• CritAppAdminDownFast (poll)
• CritAppDownNotify (alarm)

Events Sent to OpenView

Events Sent to OpenView by SnmpresCritAppStatus summarizes the events this behavior model sends to OpenView:

Optional Customization

Below is a list of behavior model settings that you might want to customize to suit the requirements of your site.

---

   It's a good practice to rename the behavior model objects that you modify. Whenever you import a model, NerveCenter will overwrite objects with the same name.

---

• Set timers for persistence
• Change Inform to Inform Platform for Netcool, TME, Unicenter

CIAgent Customization

The following is a list of sample CIAgent configurations that you might want to customize to suit the requirements of your site:

• On Windows, the configuration file for the critical applications agent is:
     C:\etc\srconf\agt\critagt.cnf

  Below is a sample entry for monitoring the DNS service:

  critAppProcEntry 2 DNS "net start dns" "net stop dns" 1 true 3000 true false \ true

• On UNIX, the configuration file for the critical applications agent is:
• /etc/srconf/agt/critagt.cnf

  Below is a sample entry for monitoring sendmail:

  critAppProcEntry 1 sendmail "/etc/rc2.d/S88sendmail start" "/etc/rc2.d/S88sendmail stop" 1 \
true 3000 true true true

The true parameter in these examples tells CIAgent to restart the application if it fails. Make this parameter false when you do not want CIAgent to restart the application.
