Plotting points on a metric graph

[ejlorson]

I am running Nagios XI 5.4.8. In this situation I am polling for metrics with SNMP and getting SNMP traps.

I have system TEST. I am polling for system load and receiving SNMP traps for this system, and can see the graphs of system load and the latest trap in Service Status.

For system TEST need to create a graph of the 5 minute system load metric and overlay it with the date/time of each trap alert. The goal is to visually identify the system load for each incoming trap. Is there a way to create such a graph in Nagios XI, or do I have to use another tool?

Or is there another method of associating this data that I am not aware of?

Thanks,
Eric

For visualization around traps, you may want to think about sending them.to NLS. (Or forwarding them)

The reason being is NLS will allow you to work with / manipulate the data as you please.

Thanks @tacolover101!

You might also want to look at Cacti: https://assets.nagios.com/downloads/nag ... ide_XI.pdf

Thanks to both of you. We are committed to splunk at my work so adding another log server probably won't be an option.

Cacti looks like it will give me the graphing flexibility I am looking for. Can you recommend a plugin for this?

Thanks,
Eric

Depends on what you're looking for, but searching the Nagios Exchange there seems to be a few out there.

Let us know if you have any more questions.

After looking at cacti I don't think it is what we need. It seems to want to talk SNMP to our hosts - during the install it is trying to change snmpd so it will let cacti make queries. We just need something to graph the data we already have in Nagios better. Also, It does not support SNMPv3 from what I can see, which is a dealbreaker for any SNMP tool we use.

What other options are there for graphing the data I already have in the Nagios DB?

Just want to clarify something here, Nagios XI does not store performance data in a DB. The data is stored in Round Robin Database (RRD) files and if you find a solution that does it better than Nagios XI already does, we would like to know about it!

There are a few options to graph out of RRD files, but IMO Nagios XI does the graphing better using highcharts.
