quick action item

[btemple]

I was wondering if you guys know of a way to run TOP from the Quick Action screen ? I know you can add custom items but I am not sure what script could be run in the background to produce TOP results remotely ?

Here's one one you can do it. I have a host that I am monitoring via NRPE. I set up the following command on the remote box (client):

Code: Select all

command[check_top]=top -b -n 1

and restarted xinetd:

Code: Select all

service xinetd restart

I made sure it works from the command line on the Nagios XI server:

Code: Select all

/usr/local/nagios/libexec/check_nrpe -H x.x.x.x -c check_top

I put the command in a bash shell script, called "top.sh" in the "libexec" directory:

Code: Select all

[root@testbox libexec]# pwd
/usr/local/nagios/libexec
[root@testbox libexec]# cat top.sh
#!/bin/bash

/usr/local/nagios/libexec/check_nrpe -H x.x.x.x -c check_top
exit 0

I added the command (script) to the "Actions" component:

Admin->Manage Components->Actions->Edit Settings

and clicked on "Apply Settings".

Now, when I click on my host under "Home->Host Detail", I can see the "Top" link under "Quick Actions":

When I click on it, I can see the top output:

this look very good thank you !

Check it out and let us know if you have any questions.

[btemple]

This is what we are looking for but, we are going to try to use check_by_ssh instead of NRPE if possible

[btemple]

this is working from command line need to figure out the quick action part...

-------------------------------
su nagios top.sh

------------------------------
top.sh

#!/bin/bash
/usr/local/nagios/libexec/check_by_ssh -H xxxxx -C "top -cSbn 1"
exit 0

Need to figure out how to inject the name of the server from the quick action to the -H .....

[ssax]

What you could do is edit the quick action and set the command to:

Code: Select all

/usr/local/nagios/libexec/top.sh '%hostaddress%'

Then change the top.sh script to:

Code: Select all

#!/bin/bash
HOST=$1

/usr/local/nagios/libexec/check_nrpe -H $HOST -c check_top
exit 0

Then you should be golden!

This is the last piece, I need to make the quick action run in the context of my nagios account , I think it's running as root


From the launched screen ...

Running: /usr/local/nagios/libexec/top.sh '172.29.10.169'
Remote command execution failed: Could not create directory '/var/www/.ssh'.

[tgriep]

Did you setup password-less login by ssh for that host?
If not, you need to following the instructions below.
https://assets.nagios.com/downloads/nag ... ng_SSH.pdf

For every host you want to use the quick action item, you will need to follow that procedure.

Edit.

I forgot to add that the Quick Action Item runs as apache so the password less login will have to be setup as the apache user.

And the command will have to be edited to use the nagios login like below.

Code: Select all

/usr/local/nagios/libexec/check_by_ssh -H xxxxx -C "top -cSbn 1" -l nagios

Ok is there anyway to make the quick launch use the "nagios" account instead of "apache" ?
