monitor cpu utilization via ssh agent

[shakman]

I'm trying to monitor a set of systems where installing the agent is not an option (long story, don't ask.) I have successfully setup other monitors to report back on filesystem usage, memory utilization, etc., but for some odd reason, I absolutely cannot get good CPU utilization data back from the target systems. I'm trying to pump this command to the target via the SSH Agent:

iostat -c | sed -n '4p' | awk {'print $6'}

Running this manually via command-line ssh, it works great and gives me exactly what I want. However, when I put this into the item configuration, it gives me nothing. Just for kicks and grins and to confirm I'm not mad, I changed the command to be:

iostat -c | sed -n '4p' | awk {'print $6'} > /tmp/idlecpu;cat /tmp/idlecpu

I'm at a loss. Any help is greatly appreciated.

Do you already have inspected the log file for errors?

[shakman]

Yes, I checked the log and turned on debugging for the server. The only indication of a problem I'm getting is a "1" return code from the ssh session. Not especially helpful.

what happens if you try:

iostat -c | sed -n '4p' | awk '{print $6}'

or:

iostat -c | sed -n '4p' | awk '{print $$6}'

or:

iostat -c | sed -n '4p' | wc -l

or:

echo 42

I *FINALLY* convinced the system owners to go with SNMP monitoring. I'm getting what I need now.

Thanks.

Hi Shakman,

Please could y
ou share how did you manage to get all the information (Memory, cpu...) using snmp?

I am in the process trying to get the same information and it getting complicated.
I have created a small program with JAVA and I could get access to any router via their IP address and I did manage to get information from the router such as NAME, TIME-UP, Object

I would really appreciate if any one can tell me how I monitory every interface in the router if that possible?

what OID I should use?
how i should configure the router to give me such information?

Many thanks
