CPU and memory utilization by particular process on Linux

[ArutwarS]

Hello,

We want to monitor the CPU and memory utilization by particular process on Linux environment.
I have tried getting cpu and memory utilization by using plugin check_snmp_process_wizard.pl.
[tcadmin@1691398-prd-tc1 bin]$ /usr/local/nagios/libexec/check_snmp_process_wizard.pl -H <host_ip> -C public -r -n tcadmin -m 100,200
I am getting error ERROR: Alarm signal (Nagios time-out).
Can you please explain where I am going wrong.

Is this server using SNMP version 2c?

Try

Code: Select all

/usr/local/nagios/libexec/check_snmp_process_wizard.pl -H <host_ip> -C public -r -n tcadmin -m 100,200 -2

Do you have an SNMP daemon listening on the machines you want to monitor? And do you have the snmpd.conf file on those machines configured correctly?

This may help, if you haven't seen it:

This machine we have has the SNMPd running:

Code: Select all

#  /usr/local/nagios/libexec/check_snmp_process_wizard.pl -H 192.168.0.4 -C community -r -n sshd -m 100,200 -2
1 process named sshd (> 0), Mem : 5.2Mb OK

This one does not:

Code: Select all

[root@localhost scripts]#  /usr/local/nagios/libexec/check_snmp_process_wizard.pl -H 192.168.0.2 -C community -r -n sshd -m 100,200 -2
ERROR: Alarm signal (Nagios time-out)

If you do have the daemon running, but the protocol version doesn't match, you're pointed to the wrong port, the community string isn't right, or something is blocking SNMP traffic, you might still get that error.

Does that help?

You can perform an nmap scan to see if that port is open to that server. Run this command on your XI server:

Code: Select all

nmap -Pn -sU -p U:161 xxx

Where xxx is the address of the SNMP device.
