check_snmp, performance graph and graph explorer discrepancy

[iptribe]

Hi,

We have a linux box being monitored in nagiosxi. One of its services configured is Active Sessions. We are getting the values correctly, however the value in graph explorer is different.

when run via command line:

$ /usr/local/nagios/libexec/check_snmp -H x.x.x.x -P 2c -o globalStatActiveCalls.summaryPeriod1Current5Minutes -m /usr/share/snmp/mibs/perimeta.mib
SNMP OK - 4 | PERIMETA-MIB::globalStatActiveCalls.summaryPeriod1Current5Minutes=4c

in GUI mode:

Performance Graph does not show for this service.

Graph Explorer Value is different:

Thanks in advance for those who will help.

Below is the rrd and xml file.

PROD_SSC_1_Active_Sessions.xml

PROD_SSC_1_Active_Sessions.rrd

Please run this command:

Code: Select all

tail -f /var/log/httpd/error_log /var/log/httpd/ssl_error_log

Then go to the performance graph that doesn't show and post any error that the command outputs (if any).

I'll take a look at the RRD while you do that.

Hi,

This is what I got. Though the error came up even before I go to the performance graph.

Please go to the details for that service and post a screenshot of the "Advanced" tab which is to the right of "Performance Graphs".

There might be an issue with the long label returned for the performance data. Lets shorten it by adding the -l label option to your command like below.

/usr/local/nagios/libexec/check_snmp -H x.x.x.x -P 2c -o globalStatActiveCalls.summaryPeriod1Current5Minutes -m /usr/share/snmp/mibs/perimeta.mib -l ActiveCalls

Then you will have delete the old graph and data files and then the graphs will recreate themselves in about 20 minutes.
Run this to delete them.
rm /usr/local/nagios/share/perfdata/RCS-PROD-SSC-01/PROD_SSC_1_Active_Sessions.*

Wait a while and post back the results.

The graph for the service is now being shown under Performance Graph. However, we are still getting invalid value as shown below. Same data is seen under Graph Explorer.

We are looking at the graphing issue with check_snmp and counters. As soon as a fix is found, we'll post back.

Hi tgriep,

Appreciate it.
