Bandwidth monitoring

Post by arupsgt »

Hello

We are currently evaluating Nagios XI. I have configured SNMP on one of our virtualized proxies (Cisco WSA) and setup monitoring in Nagios. This appears to be working, however, the inbound and outbound data are more or less the same. During testing, there was no one else using the proxy and all I was doing was downloading a 5Gb file, nothing was being uploaded.

Do you have any thoughts as to why this might be and, if so, how to resolve it?

Thanks

Please post the configuration of your service/s so that we can troubleshoot the command and output further.

Can you send a screenshot of the graph and status output for that bandwidth service? They can both be found under "Service Details" and clocking on the service name, then going to the Advanced and Performance Graphs tabs.

Also, what sort of device is it that you are monitoring?

Did you run your check right after you downloaded the 5GB file? The mrtg cron job runs every 5 min, then the data is put into the rrd file...
When you go to the Home->Service Detail->Port 1 Bandwidth->Performance Graphs, do you see a spike in the graph, corresponding to the time you downloaded the file? Can you upload the rrd file (/usr/local/nagios/share/perfdata/10.128.38.17/Port_1_Bandwidth.rrd)?

Thanks. Screenshot attached. It is a Cisco WSA virtualized proxy. It is a test device, hence there isnt much traffic and hence why I downloaded the 5Gb file as a test. The inbound and outbound figures are always very similar, even though there isnt anything being uploaded.

Could you upload these 2 files so we can review them?

Code: Select all

/usr/local/nagios/share/perfdata/10.128.38.17/Port_1_Bandwidth.rrd
/usr/local/nagios/share/perfdata/10.128.38.17/Port_1_Bandwidth.xml

I dumped the rrd file and is looks like the data is different.
Try and delete the rrd and wml files which will recreate them and see if they still are showing the in and out as the same.
Can you upload the mrtg config file for that host?
It can be found in /etc/mrtg/conf.d/10.128.38.17.cfg
