Unable to get Cisco switch to show utilization

Can you outline the steps that you've done so far to set this up and what you're currently seeing for this particular switch?

On the switch itself, I've enabled SNMP and created a unique community string.

In Nagios XI, I went to Configure > Monitoring Wizard > Switch/Router option.

Typed in IP of switch, entered unique SNMP community string, selected Cisco for vendor, port number, scan interfaces and left monitoring defaults the same.

Gave the switch a host name, unchecked ping, selected which ports to monitor, named the ports and unselected port status checkboxes. I left the default bandwidth options the same.

Applied setting successfully.

I use minemap currently as a visual aid so in minemap for that switch, circles go green, and when I hover, the in/out Mbps are blank. If I click on the actual port being monitored, the in/out is still showing blank. I copied a 4gb file from the server through port 1 and it still shows no data.

I set this same switch up as a test on the previous VMware image and was able to see bandwidth utilization.

Thanks

Also, I've used IE9 & Chrome to view with no difference.

I also cannot see any performance graphs on the switch ports but do remember seeing them before when it was working.

Brian,

Can you try doing a walk against the switch?

At the command line:

snmpwalk <IP of switch> -c <comm string> -v<snmp version number>

Is that give you results back? What kind of switch is it?

If the walk worked, lets work our way to MRTG RRDs. Go to the /var/lib/mrtg/ directory and run this

rrdtool fetch <RRDfilename> AVERAGE

Are these all NaNs or 0?

If the walk didn't work, then its a community string/firewall issue.

Yes, I did get results back when running snmpwalk command.
It is a Cisco SG 300.
I don't see a mrtg directory in the lib directory.

Re-added switch and prior to the circles (ports) turning green, it is orangish and shows the message:
Port x Bandwidth Unknown: /var/lib/mrtg/ (ip).rrd does not exist.

Seems to me I'm missing a service or something here?

Any update for me yet?

Yeah, it looks like there may be a permissions issue with the /var/lib/mrtg directory. Can you verify the ownership of that directory for me?

ll /var/lib
ll /var/lib/mrtg
