Previous posts suggest the datastore may be disconnected.

That said, can you PM me your Profile? You can download it by going to Admin > System Config > System Profile and click the Download Profile (not Show Profile) button in the top right corner. If for whatever reason you cannot download the profile, please put the output of Show Profile in the thread (that will at least get us some info).

After you PM the profile, please update this thread. Updating this thread is the only way for it to show back up on our dashboard.

UPDATE: profile shared with techs.

Hi,

Today we have added one more VM Host 10.x.x.31 and it is showing critical alert same as in our previous conversation to the Datastore usage for VMHost service.

Please find the attached screen shot.

Note: Attached updated profile zip.



Thanks,

Can you run a check from the command line against each datastore (for troubleshooting purposes), and show the output?

Example:

Code: Select all

/usr/local/nagios/libexec/check_esx3-0.5.pl -H <ip address> -f <auth file> -l "VMFS" -s "CS1-Datastore00-VM"
/usr/local/nagios/libexec/check_esx3-0.5.pl -H <ip address> -f <auth file> -l "VMFS" -s "CS1-Datastore03-VM"
/usr/local/nagios/libexec/check_esx3-0.5.pl -H <ip address> -f <auth file> -l "VMFS" -s "CS1-Datastore04-VM"
/usr/local/nagios/libexec/check_esx3-0.5.pl -H <ip address> -f <auth file> -l "VMFS" -s "CS1-Datastore05-VM"
/usr/local/nagios/libexec/check_esx3-0.5.pl -H <ip address> -f <auth file> -l "VMFS" -s "CS1-Datastore09-VM"

Try and upgrade the plugin to version 0.7.1 and see if that fixes the error.

First, login to the XI server as root and make a backup of the existing one by running the following.

Code: Select all

cp /usr/local/nagios/libexec/check_esx3.pl /usr/local/nagios/libexec/check_esx3.pl.old

Then run the following to install a required Perl Module for the new plugin.

Code: Select all

yum install perl-Nagios-Plugin

Then download this updated plugin to your PC.
https://github.com/shinken-monitoring/p ... ck_esx3.pl

After it is downloaded, login to the XI GUI and go to the Admin > Manage Plugins menu
Browse to the new plugin and then click on the Upload Button.

Wait 10 minutes and see if you are still receiving the error for those Datastores.

Hi,

As you suggested in the previous post I have implement the same steps but no result, still same critical error only for those two VM hosts.


Thanks,

[rkennedy]

Please show us the commands you ran, and what the new result is. The issue may lie in the plugin so anything you can provide will help.
