[Nagiosplug-help] R: check_by_ssh timed out issue

[Valerio.FABRIZIO at sungard.com]

Hi

I've had the same problem with some remote checks, I solved it by adding a "-u" in the command. ("u" turns a time out critical into a time out unknown message). This works only if your plugin accept this value. 

 

 

Regards 

Valerio

I get that, but with the check script the "timed out" warning comes back as a critical.

 

I might be stuck with this as there is no "switch" to add to check_by_ssh for timed out values to not raise a critical condition as I've seen in some other scripts.

You should be able to set the alert so that if you get an 'unknown' response then  will not alert.  I am unsure where this is set on the command line, my copy of Groundworks uses a web browser front end and it is set as below:

 

 

 

If I untick the box for 'unknown' then save your configuration then I only get emails for Warning and Critical alerts.

Hi List,

 

I have Nagios currently using check_by_ssh (check_by_ssh v2002 (nagios-plugins 1.4.13)) to check some of my remote servers, it calls a log script on the remote server and the log script returns a warning if the log files matches the criteria.

 

Every now and then, the check_by_ssh script gets timed out, and returns the message below.

 

Is there a way to suppress this at the Nagios box, so that Plugin Timed Out messages do not get emailed as "Critical"?

 

Anyone know? Below is my command definition..

 

define command{

                command_name             van-oppy-pro_data450

                command_line $USER1$/check_by_ssh -H someserver -p 22 -i /home/nagios/.ssh/id_dsa -t 10 -C "/home/nagios/plugins/check_logfiles -t 30 -f /home/nagios/log_conf/usr1_data450.lg"

}

 

Nagios alert returned when the box being queried is very busy (this does not happen often, but creates a unwanted false positive warning):

 

CRITICAL - Plugin timed out while executing system call
