Problems with dynamic paging file size in Windows

[XorroX]

Hello Guys,

We are using Zabbix 2.4.5 and monitor the Zabbix Agent item "system.swap.size[,free]" on Windows Hosts.

Sometimes it occurs, that Zabbix shows 0Byte for this item.

Do you have any idea why this is happening?

Thanks for your help!

Pagefile Clearing

Hi,

May at shutdown time if you enabled ClearPageFileAtShutdown :

https://support.microsoft.com/en-us/kb/314834

This setting clears the pagefile for security reason.

No shutdown

Hi,

Thanks for your feedback, but unfortunately this is not the solution for our case.

The affected servers are never shut down...

Any other ideas?

Thanks!

Performance counters

Hi again,

So it could be an issue with performance counters. Is the CPU really high when you get 0 for the pagefile size?

Normal Values

Hi,

Thanks again for your feedback!

But both RAM and CPU have normal values when this "error" appears.

Which perf counter?

Which perf counter are you using?

[XorroX]

No perf counter

Hi,

We are not using perf counter in this context.

These items are configured as Zabbix Agent items.

Perf counters and Zabbix

Hi,

In fact it does.

And it seems the calculation made to find values are not so simple to get. A bug is open in 2.4.1 https://support.zabbix.com/browse/ZBX-9619

For more information, to calculate the value accurately: https://support.microsoft.com/en-us/kb/2860880

And the API used to find the base of the calculation: https://msdn.microsoft.com/en-us/lib...=vs.85%29.aspx

I think you have to wait the bug ZBX-9619 to be closed.
