Nagios Support Forum

Hi All,

I recently built a brand new server (Ubuntu 20.04) and installed 5.7.1, since upgraded to 5.7.2

I have noticed on two occasions over the past 2 weeks that the services that monitor switch link bandwidth stop logging. A check of their values is 0.0 and the graphs display either gaps or a message saying "nothing to display" or something similar. A reboot of the server fixes the problem.

The command that is being used to monitor the switch ports are all simliar to this
check_xi_service_mrtgtraf!10.174.64.34_16.rrd!500.0,500.0!800.0,800.0!M!!!!

Cheers,
Chris.

Hi

I believe you maybe hitting some the default configuration thresholds the files are spooling up. You can verify this by running the following commands to count the files: Follow the instructions in the following KB article to increase the timeout and load_threshold on your server, and let me know if you notice an improvement.

Hi Benjaminsmith,

Thanks for the response. I ran those two commands and get either 0 or 2 at various times.

I've enabled the logging and increased the timeout and will wait to see if the problem reoccurs.

Sounds good. We'll keep this thread open.
