3PAR check script

This is a good check but fair warning- the power supply check does not return a critical code if it detects an issue

there are updated versions elsewhere on the web

Hi,

On https://github.com/pgh2011/check_3par there is new version of the script with a fix.

Fixed issue when there are more then 150 physical disks.

Is works on the commandline but not in the Nagios check.

Output when the check via Nagios is started:

line 481: 100 - ( ( * 100 ) / ) : syntax error: operand expected (error token is "* 100 ) / ) ")
check_3par ERROR: ERROR Wrong command 'check_cap_ssd' .

Hello everybody,
on GIT https://github.com/qaxi/nagios-check_3par
there is version 5 of the script.

there is Quorum Witenes checking for Peer Persitence

Same problem here, 3PAR is stillasking for a password after following succesfully SSH key process

I have completed this well working script with other scripts and some test usefull for us:

Check volume : https://exchange.nagios.org/directory/Plugins/Operating-Systems/%2A-Virtual-Environments/VMWare/Check_3par_volume/details

check power supply node and check power supply cage

and check SSD found upper

If you want to have an error if the ssh connection is not working and ask the password to nagios add this parameter at the end of the ssh command: -qo PasswordAuthentication=no

CONNECTCOMMAND="ssh $USERNAME@$INSERV -qo PasswordAuthentication=no"

I did all what you say, and everything was good, but when I try to connect to 3Par it still ask me for password.
I tried with root and nagios but always the same problem.

Works fine in Nagios 3, I used the SSH connection.
When in the instructions it says:
"Log in to the server with the 'nagios' user" I did (as root):

# su - nagios -s /bin/bash

because my nagios user didn't have shell.

In case someone is interested. Not perfect, but it does the job.

Error: Service check command 'check_3par_cap_fc' specified in service 'FC disks capacity' for host 'ieat3par-01' not defined anywhere!

I'm not a linux expert but found the instructions really easy to follow

The check is great and monitors everything successfully.

One little bug I found was that the power supply check does not return "UNKNOWN" when it is unable to connect to the 3PAR, all the other checks are able to do this...

I have just installed 3par check plugin for Nagios and it's working excellent ! Very easy to implement using installation guide provided.
