Monitoring via SNMP

[groque]

Hi all,

I am currently testing SNMP monitoring with my ProCurve 2910al's and Cacti

I am trying to monitoring an entire VLAN I waited 10 minutes and still nothing I just wanted to know if I am doing something wrong here?

And is it possible to monitor CPU usage on the ProCurve?

Thanks

Not sure about Cacti, but have you tried exploring ProCurve's own management software[http://www.procurve.com/products/management/ProCurve_Manager/overview.htm] that would allow you to monitor ProCurve devices in a easier and efficient way?

For CPU usage, you can check quering the scalar 1.3.6.1.4.1.11.2.14.11.5.1.9.6.1 - have to double check if that's available in 2910's..

addendum: 2910's menu access feature display's "CPU Utilization" .

Navigate to Menu > "Status and Counters"
> "General System Information"

Hmm, I've not tried that, I'm monitoring specific interfaces with cacti but not any 'VLAN interfaces'. I'll give it a try and let you know what I get.

Ok, so I as I suspected that doesn't return any values.
The VLAN "interfaces" aren't real interfaces hence there are no traffic counters associated with them.

Oh and to monitor CPU usage you can create your own MIB variables to monitor as per the thread here:

http://forums.cacti.net/about4143.html

Or you can just modify the existing "Cisco CPU usage" data templates which is what I did as we don't have any Cisco devices in our network :)
To that :

- Go to the Cacti web interface -> Console
- Select "Data Templates"
- Select "Cisco Router - 5 Minute CPU"
- Near the end of the page edit the OID to the one Javed kindly provided (note it requires a leading "." as per the exisiting OID)

Then :

- Select Devices
- Select the device you want to graph cpu usage for
- Select "Create graphs for this Host"
- Under "graph templates" select "Cisco CPU usage"
- Click on the "create" button down the bottom of the page
- Wait 15 minutes and check your graph :)

Sorry, you need a .0 on the end of that value, so enter : .1.3.6.1.4.1.11.2.14.11.5.1.9.6.1.0
