Are the active sessions always zero when they are polled?

No, they are not always zero. Please see below.

The check_snmp_gauge.cfg file may have been corrupted when I uploaded it last week.
I replaced it with a new copy so could you re-download it to your Nagios system, delete the rrd and xml files and see if that resolves it.

Is it the same check_snmp_gauge.cfg file attached in previous page? I have re-downloaded it and deleted the rrd and xml files. New graph generated but still with the same data.

Yes, the file from the previous page is good. I deleted the bad one and uploaded a good copy. Now to trouble shooting.

Edit this file /usr/local/nagios/etc/pnp/process_perfdata.cfg
Change this from to Save the changes and run the following in a shell.
Delete the RRD and XML file again and schedule an immediate check of that service 3 times and upload the output of the tail command.
Please upload it as a txt file as it will be quite large.

After that, you can put the LOG_LEVEL back to 0.

Please see the attached logs.
I have 3 servers having the same issue with Active Sessions service graph.

RCS-PROD-SSC-01, RCS-PROD-SSC-02 and RCS-PROD-SSC-03.

The log file didn't show that the check used the check_snmp_gauge template.
Can you edit that service and remove the service template "check_xi_service_snmp" that is assigned to the service?
Can you post how that service is defined?
Go in to Core Config Manager > Service and find that service and click on the Floppy icon for that service copy and paste the configuration in code wraps here?

Can you run the following and post the output here? Can you change to this folder
/usr/local/nagios/share/perfdata/RCS-PROD-SSC-01
Run the rrdtool on the Active Session rrd file like below and post back the top 15 lines?

So far the settings look like they should work.
Can you upload the /usr/share/snmp/mibs/perimeta.mib, and the rrd and xml files to this post?
