How to monitor Disk IO and CPU load using SNMP in Nagios

[yunushaikh]

Hello Sir,

i want to monitor Disk I/O and CPU load ( If possible load on every core) using snmp. Is there any plugin which I can use.

Re IO - I'm assuming you're referring to the Linux platform. If so I'm unaware of any OIDs or SNMP plugins that monitor IO. There are disk counters that you could potentially adapt to an MRTG pool after which you could use check_mrtgtraf to suck the data into Nagios.

Here is a plugin that I found for Disk IO:

https://exchange.nagios.org/directory/P ... MP/details

Code: Select all

/usr/local/nagios/libexec/check_diskio_ucd.pl -H X.X.X.X -C community -s 2 -d sda1 -w 30 -c 50

For CPU you can use:

https://exchange.nagios.org/directory/P ... ad/details

Code: Select all

/usr/local/nagios/libexec/check_snmp_load.pl -H X.X.X.X -C community -w 80 -c 90

Hello Sir,

DISK I/O worked fine but CPU load is asking me snmp login info

I dont want to use login information for snmp
Is there any way

./check_snmp_load.pl -H X.X.X.X
Put snmp login info!
Usage: ./check_snmp_load.pl [-v] -H <host> -C <snmp_community> [-2] | (-l login -x passwd [-X pass -L <authp>,<privp>]) [-p <port>] -w <warn level> -c <crit level> -T=[stand|netsl|netsc|as400|cisco|cata|c5500|nsc|fg|bc|nokia|hp|lp|hpux] [-f] [-t <timeout>] [-V]

When I give command as

./check_snmp_load.pl -H X.X.X.X -w 80 -c 90 -C public

with parameter -C as public then it gives the output

What is the difference between doing -C and without running -C. Without -C it asks for snmp login information?

I assume that when you do not include -C community it may default to SNMP v3, so make sure to add the -C community since it's required.

Thanks for your reply. I was able to do that. You can close this thread.
