Switches CPU Utilization & Memory Monitoring

[raamardhani7]

Hi Team,

I wanted to monitor CPU and Memory utilization for Switches and routers. snmpwalk is working fine and when I am running the below command for cpu utilization, I am facing the below issue. Also please let me know how can I monitor memory utilization for the same.

Code: Select all

./check_snmp_load.pl -H xx.xx.xx.xx -v2c -C public -t 30 -w 50 -c 90 -p 161
Alarm at 15 + 5
SNMP v2c login
ERROR: Description table : Requested table is empty or does not exist.

What is the make and model type of the device that you are trying to monitor?
Can you re-run the snmpwalk to the device and add -On to the command and post the output here so we can review the OID's from the device?

It is CISOC router. Model number: WS-C3750X-24P

attaching the snmpwalk command with -On

CPU check :
stand : standard MIBII (works with Windows),
can handle multiple CPU.
netsl : linux load provided by Net SNMP (1,5 & 15 minutes values)
netsc : cpu usage given by net-snmp (100-idle)
as400 : as400 CPU usage
cisco : Cisco CPU usage
cata : Cisco catalyst CPU usage
c5500 : Cisco ASA 5500 CPU usage
nsc : NetScreen CPU usage
fg : Fortigate CPU usage
bc : Bluecoat CPU usage
nokia : Nokia CPU usage
hp : HP procurve switch CPU usage
lp : Linkproof CPU usage
hpux : HP-UX load (1,5 & 15 minutes values)

What is the result when you run it with -T cisco?

It looks like this plugin is a bit different, see this page -
https://exchange.nagios.org/directory/P ... ad/details

-2, --v2c
Use snmp v2c

Looks like this script functions a little bit differently, try this -

Code: Select all

./check_snmp_load.pl -H xx.xx.xx.xx -2 -C public -t 30 -w 50 -c 90 -p 161 -T cisco

Hi rkennedy,

I have tried the plugin mentioned above and still i am facing the same issue.

The Cisco devices have 3 separate CPU loads, 5 second, 1 minute and 5 minute so the warning and critical options have to be set for all 3 loads. Try running the command like so.

Code: Select all

./check_snmp_load.pl -H xx.xx.xx.xx -2 -C public -t 30 -w 50,50,50 -c 90,90,90 -p 161 -T cisco

Let us know if this helps.

Looks like this is working now.

Could you please let me know how can I perform Bandwidth monitoring?

I was able to find this plugin, https://exchange.nagios.org/directory/P ... h3/details - would this work for you?
