monitoring switch port channel bandwith?

[so_dt]

Hi,

I´d like to monitor the bandwidth usage of switch port channels.
the config wizard in nagios xi does list them as link aggregate, but when adding it as service, the shown usage is far below what is really in use - double checked via adding the individual member ports of the channel. should this usually work?

Can you provide screenshots of the what XI reports for bandwidth usage and what your other source reports?
Is your other source getting these values via SNMP also?

From XI > Configure > CCM > Services > [Your switch service] > Run Check Command what is the full output from running that?

What is the output of this?

Code: Select all

# LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg

Hi avandemore,

the output of check commant test is this:

Code: Select all

COMMAND: /usr/local/nagios/libexec/check_rrdtraf -f /var/lib/mrtg/172.16.96.16_636.rrd -w 1800.00,1800.00 -c 1900.00,1900.00 -l M
OUTPUT: OK - Current BW in: 54.28Mbps Out: 63.57Mbps|in=54.283849Mb/s;1800.00;1900.00 out=63.574017Mb/s;1800.00;1900.00

unfortunately I cannot run the second at the moment, as I have no access to the server itself right now.

Can you PM or attach the file /var/lib/mrtg/172.16.96.16_636.rrd?
