uptime monitor for ESX host

[preethu.d]

Hi,

Is it possible to monitor uptime for ESX host which is added in Nagios using vmware wizard (user name and password). If yes, how this can be done ?

Please try this command against it:

Code: Select all

/usr/local/nagios/libexec/check_vmware_api.pl -H X.X.X.X -u 'youruser' -p 'yourpassword' -l "uptime"

See here for the -w or -c thresholds if you want to set them:

Hello @preethu.d

Appears from the screenshot that the command is unable to read the Auth config let's make sure that the permissions are correct:

Code: Select all

chown nagios:nagios <yourauthfile>

Then list it:

Code: Select all

ls -l

Let us know how that looks,
Perry

Hi Perry,

I have made the changes. But still getting the same error.

For this ESX host, auth file was in the below path.

/usr/local/nagiosxi/etc/components/vmware/

earlier it was "apache nagios", after changing permission it is showing as "nagios nagios"
I did a run check command after making the changes, but it was giving the same error.

If you look at the command from your screenshot at the top you see this defined:

Code: Select all

$USER1$/check_vmware_api.pl -H "$HOSTADDRESS$" -f "$ARG1$" -l "$ARG2$" $ARG3$

The -f option is to point to an auth file:

Code: Select all

 -f, --authfile=<path>
   Authentication file with login and password. File syntax :
   username=<login>
   password=<password>

Taken from the plugin help output:

Code: Select all

/usr/local/nagios/libexec/check_vmware_api.pl

So what the nagios process will do is replace the $MACRONAME$ macros in the command you have selected with the actual values before running them.

So with everything in $ARG1$ the command would translate to this which isn't proper:

- $USER1$ = Taken from /usr/local/nagios/etc/resource.cfg and points to /usr/local/nagios/libexec
- $HOSTADDRESS$ = Will use the hosts Address field that the service is attached to
- $ARG1$ = -u 'username' -p 'password' -l "uptime"

Code: Select all

/usr/local/nagios/libexec/check_vmware_api.pl -H "X.X.X.X" -f "-u 'username' -p 'password' -l "uptime"" -l ""

Go edit to the service in Configure > Core Config Manager > Commands and set the $ARGn$ values based on the command that it's using:

Code: Select all

$USER1$/check_vmware_api.pl -H "$HOSTADDRESS$" -f "$ARG1$" -l "$ARG2$" $ARG3$

So you would want:

$ARG1$ = /usr/local/nagios/libexec/your_auth_file
$ARG2$ = uptime

Then click Save, Apply Configuration, and Force a check to see if it is now working and let us know the results.
