Check_smb_status.sh Plugin

[Berto]

Hello,

Yesterday I downloaded the check_smb_status.sh plugin from here https://exchange.nagios.org/directory/P ... sh/details and it does exactly what I was looking for. I would like to display the results of that plugin in the Nagios XI web interface and that's where my issue is. I followed this doc https://assets.nagios.com/downloads/nag ... ios-XI.pdf and when setting up the service and using the 'Test Check Command' button I see the command and the output is blanked. In the 'Service Status' page under 'Status Information' I see (Return code of 255 is out of bounds). If I run ./check_smb_status.sh locally on the host it displays fine, and if I run from the command line on the nagios server ssh <hostname> /opt/nagios/libexec/check_smb_status.sh I get the proper results also.
My command is ssh <hostname> /opt/nagios/libexec/check_smb_status.sh as it seems the plugin doesn't recognize using the -h $HOSTADDRESS$ macro, so I'm a bit confused on what to do now.

Am I going about this the wrong way? Is the command I created not the proper method to get the info back to display on the web interface?

Thanks,

Please go to Configure > Core Config Manger > Commands and click the blue floppy disk icon next to the command and paste the full definition of that specific command.

Then go to Configure > Core Config Manger > Services and do the same for the service that you set up.


Thank you

Can you show us the command and service definition that you are using?

CCM->Commands->View Config (the diskette icon)
CCM->Services-><your service>->View Config (the diskette icon)

I set up two "test" services, and both are working fine. Here's my configs:

Code: Select all

define service {
	host_name			CentOS6-SSH
	service_description		Check SMB Status
	use				generic-service
	check_command			check_xi_by_ssh!-C "/usr/local/nagios/libexec/check_smb_status.sh"
	max_check_attempts		5
	check_interval			5
	retry_interval			1
	check_period			xi_timeperiod_24x7
	notification_interval		60
	notification_period		xi_timeperiod_24x7
	notifications_enabled		1
	contacts			nagiosadmin
	_xiwizard			sshproxy
	register			1
	}

define command {
       command_name                  		check_xi_by_ssh
       command_line                  		$USER1$/check_by_ssh -H $HOSTADDRESS$ $ARG1$ $ARG2$
}

define service {
	host_name			CentOS6-SSH
	service_description		Check SMB Status 2
	use				generic-service
	check_command			ssh!/usr/local/nagios/libexec/check_smb_status.sh!!!!!!!
	max_check_attempts		5
	check_interval			5
	retry_interval			1
	check_period			xi_timeperiod_24x7
	notification_interval		60
	notification_period		xi_timeperiod_24x7
	notifications_enabled		1
	contacts			nagiosadmin
	_xiwizard			sshproxy
	register			1
	}

define command {
       command_name                  		ssh
       command_line                  		ssh nagios@$HOSTADDRESS$ $ARG1$
}

I don't have samba configured on the remote machine, but the plugin returns a valid output:

Hope this helps.

You may want to use the check_by_ssh plugin which would work for what you are doing.
Take a look at this document for instructions.
https://assets.nagios.com/downloads/nag ... ng_SSH.pdf

Can you run the following commands and show the output?

on the client (remote machine)

Code: Select all

su nagios
/opt/nagios/libexec/check_smb_status.sh

on the nagios server

Code: Select all

su nagios
ssh nagios@<client ip> /opt/nagios/libexec/check_smb_status.sh

Hello,

Sorry was on vacation for a while and just got back to working on this. I believe half of my problem is the way the local nagios account is on the server, which I'm working on now. But to verify that the command would work, I added my username as I know that would work, and I still get a empty output when using the Test Command. If I do it from the nagios server to the host from command line it does display back;

[lnsvr0370]:(584/0)-$ ssh abeltr01@susvr0215 /opt/nagios/libexec/check_smb_status.sh
Total Users/Process: 110 Total Machines: 108 Total Files: 715

You have to be able to run the plugin as nagios user. Please run the commands from my previous post, and show the output.

I finally got this working, but I do have one question before closing out this thread. Can all plugins be graphed in Nagios? I would like to have a performance graph for this Samba service if possible and when I click on the performance graph tab, it comes up with the "No performance were found for this service." It's been 24 hours so I know there's data, just wondering if it's possible to create a graph with this plugin.

Not all of the plugins return perfdata, but this one should. Click on the service, go to the "Advanced" tab, and show us a screenshot of the page.

Also, check if the RRD and XML files were created in "/usr/local/nagios/share/perfdata/<hostname>/" directory for the problem service. If you have a RRD & XML files, you can delete them (only delete files named after the "smb" service!), and wait until they get recreated. It may take up to 20-30 min before perfgraphs start showing up.
