Hello Team,
Few months back we configured VCenter monitoring through nagios xi wizard and everything looks good.But now, All other checks are working fine for that vcenter but Datastore monitoring is taking too long to execute and failing with this error message. Few details regarding sdk & nagios xi version are provided below,

Hi,
How are you doing?
Were there any changes make to your system?
Were there any updates make to Perl modules and Perl SDK?

I found a similar forum ticket with exact same issue:
https://support.nagios.com/forum/viewto ... 1&start=30

Looks like it was resolved with the install of the below package:

Code: Select all

cpan -i GAAS/libwww-perl-6.05.tar.gz

Hi vtrac,
I tried that but still the same error. Please do the needful as other checks on same vcenter are working from same nagios but only this datastore is not working.

Hi bsanjay,
How are you doing?

There must be changes make to your remote host "100.20.55.76", since it was working before.

Please find out from your unix admin or network admin what changes were make.

Vinh

HI vtrac,
As i already informed you that other check for the same VCenter from same nagios server is working fine but only issue is with the Datastore monitoring on this VCenter.

If there is some chagnges on VCenter or password config updated then it should not work for any of the services monitored for that VCenter. Please see the attached screenshot for your refernece,

Sanjay Batkura

Hi Sanjay,
Sorry, my bad!! ...

Did you just upgraded vSphere SDK and vmware-cmd to version 7.0.0?

I checked with my teammate Sean and here is his suggestion:

I would have them increase this on their worker:
job_timeout=60
To 120 or higher, then have them restart the mod gearman worker service on that worker.

Then have them add -t 120 to that service,

Then make sure they have this or higher in /usr/local/nagios/etc/nagios.cfg:
service_check_timeout=120

Vinh

Hi vtrac,
i think i need to explain it another way. When i run the check command even from CLI it takes almost 30 minutes to return the output and the output contains lot of error message that i have attahced in text file. I can see the perf data in this error message at the end but not the status information (screenshot attached).
Apart from datastore all checks are working fine but only datastore is taking too long to complete and then finishing with error.

Hi Bsanjay,
Please share what changes were make to your system as it is very difficult for me to know what steps to take.

Also, this script was not written by Nagios as I am trying to ask development for helps.

I checked with developments, QA and supports for helps on this ..... here's one suggestion I got from Tom (from support):

I have seen in the past that the Datastores require a different permissions to be set. It was for a different plugin but that may be the issue they are having.

The may have to do something like this.

The problem is with the permissions that have been applied in the vSphere Client. For some reason assigning
the permissions at the top level of “Inventory > Hosts and Clusters” is not enough. You need to also assign the
permissions at the top level of “Inventory > Datastores and Datastore Clusters”.

Plus, the check taking 30 minutes to run is never going to work in Nagios.
If they added a lot of datastores to VMWare, that could be the issue as well.

They may need to blacklist the datastores they do not have access to.
Something like this example can be added to the command.

-o blacklistregexp -x 'ISOs|ESX|data'

Please follows the steps suggested by Tom (above) and see if it will helps!!

Best Regards,
Vinh
