Timing off after vCenter upgrade

[mvp]

Timing is off on Nagios after a vCenter upgrade. Our server guys have told me that the vCenter was upgraded to 5.5. I am attaching a screenshot of what we are seeing in Nagios. Please notice that the time is 'off' & also 'future tense' by months.

This was set-up as a Linux 64 bit, VMware image install

What is the output of the following:

Code: Select all

date

Code: Select all

cat /etc/php.ini | grep 'date.time'

I want to see if your system time has pushed out as well.

date.timezone = America/New_York

You can try removing the retention.dat file:

Code: Select all

service nagios stop
killall nagios
cd /usr/local/nagios/var
rm -f retention.dat
service nagios start

This will cause all of your checks to to go "pending" state and *should* fix the timing issue (if it hasn't been already fixed).

This resolved all the timing issues. thanks!!

I am not sure if this is a different issue, your input would be appreciated. We have had this in the past & it seemed that it was due to too many checks around the same time... bogging down Nagios - but it appears to only be affecting vCenter servers & 'localhost'. Please advise. I attached a screenshot of what we're seeing & server stats. thanks

Most likely your bogging down issue will be due to the VMware SDK used to execute the VMware checks. It's a memory and CPU resource hog which in turn causes Nagios to stop responding.

It just so happens that I've developed a Plugin that runs on a vMA appliance, which offloads the VMware checks to stop your Nagios host becoming so bogged down.

Go and download box293_check_vmware from the Nagios Exchange. Have a good read of the manual as it contains everything you need to know to get it running.

A Wizard for Nagios XI that is specific to this plugin is coming soon ...

Glad I started following this post!
I stopped all my VMware checks recently (except for ping) because of the bog-down.
Thank you for the option to offload, I have tagged this post and will implement it this fall after projects taper off

@mvp
Let us know if Box293's suggestion helped.

[mvp]

Great stuff, I will hopefully be able to do something with this & update in the next week.
Thank you!
