check_snmp return value with performance graph

Thanks.

Here is the conf file.

I think you need to remove the following from $ARG1$ field for these services=

Code: Select all

 -m NUTANIX-MIB

This is not present for the clusterIops which is working correctly

Hi,

Performance graph still takes arbitrary value from somewhere. Any other suggestion?

[cdienger]

The graph showing zero may have had settings at one point that have changed and now new data can no longer be graphed. Try removing this graph's rrd and xml file. You'll find it under:

/usr/local/nagios/share/perfdata/<hostname>/<servicedesc>.[rrd|xml]

Performance graph still takes arbitrary value from somewhere.

The graph that jumps around would be graphing the data that the device returns and it's likely the counter jumps. Are you able to check the value on the device itself or with a MIB browser?

Hi,

I have deleted performance data rrd & xml file and restarted Nagios service but it shows same result.
I have attached MIB Browser output as well.

Thanks.

Let's try to verify the requests from XI and the responses it receives.

On the XI command line run:

yum -y install tcpdump
tcpdump -s 0 -i any port 161 and host w.x.y.z -w ouputput.pcap

where w.x.y.z is the IP address of the device that is being queried. Let this run just long enough to capture a couple jumps in the graph and then use CTRL+C to stop it and PM me the output.pcap it created.

I missed the part where it's using snmp v3 and hence encrypted. Can it be switched to version 2c to help troubleshoot?

[bongbi]

Based on Nutanix documentation, v1 & v2 are not supported.

Can you provide a screenshot of the Advanced tab for the clusterIops service so that we may see the performance data field? If you check this field, do you see the value jumping as well?
