How to treat an event/notice/alarm as an outage?

Hi there,

Is there a mechanism to convert an event/notice/alarm into an outage, such
that it will be visible on the front page of OpenNMS? I monitor a fair
number of processes of different types across a number of systems -- some
are generic server processes we're all familiar with (httpd, sshd, etc.) but
some are highly-specialized vendor-specific processes that speak their own
(and usually undocumented) protocols, which makes it more of a challenge to
determine if they're in a normal state or not.

I've been able to convert some of them into monitored services via capsd and
collectd, but that's not quite ideal, as it involves creating configurations
for two or three dozen different applications, not all of which act as
network services.

I am able to monitor them via SNMP (using the 'proc' keyword of Net-SNMP) to
determine when they stop and start, and I am receiving notices when that
happens, but I'd like to make this information more public so that I'm faced
with it the instant I sign into our NMS. Is there a way to do this? I looked
through the Wiki, but couldn't really find anything that clued me in.

thanks,
Klaus

It seems to me that it should be doing this already.  If you are monitoring something from the poller-configuration and using the SnmpMonitor and you are receiving notifications from the NodeLostService event, you should be getting outages.


I looked through the Wiki, but couldn't really find anything that clued me in.

If you are looking for something that can take the events which generate Alarms but are not created by the OpenNMS Poller (i.e. Traps) and turn them in to Poller generated outages, you can use the Passive Status feature.

Hi David,

Sorry for the late reply, we had a very busy two weeks here and all of my
work with ONMS got shoved to the back, back, back burner. :-(

Anyway ...

I am indeed getting notifications via email (as per my configuration) when a
service is detected as out. What I am looking for is a way for OpenNMS to
show me on the front page that host1 has an outage because 'slapd' isn't
currently running. A lot of the services I monitor via Net-SNMP don't have
default pollers because they use weird and wonderful proprietary protocols
and ports.

Looks like the passive status keeper is where I want to look. Thanks for the
heads up.

Also, since I've seen a couple of people doing this I figured I'd follow
suit:

Linux: CentOS 4.6 (with local modifications)
Java Version:     1.5.0_18 Sun Microsystems Inc.
Java Virtual Machine:     1.5.0_18-b02 Sun Microsystems Inc.
Operating System:     Linux 2.6.9-67.0.1.mpc30smp (amd64)
Servlet Container:     jetty-6.1.9 (Servlet Spec 2.5)
Installation Method:    RPM
mib2opennms-0.3.0-1
opennms-webapp-jetty-1.6.7-1
opennms-core-1.6.7-1
mib2opennms-0.3.0-1
opennms-1.6.7-1
opennms-repo-stable-1.0-12
