Pagefile constantly >99%




We have a customer that we monitor a server for, and I'm starting to think this may be a red herring.

The server is just a bog standard HP ML110 G6 Tower server, with Windows 2008 R2 Std, 4GB RAM.

It supports 4-5 users as a file server, that's it.

We constantly get an alert from PRTG that the Page File is >99%, meanwhile there are no reports of slow downs, Task Manager reports Memory Usage at a nice 60%. Perfmon shows disks are barely being utilised.

We have tried removing the page file, and recreating it. It seems to happen at random.

How should I proceed to find out why PRTG is alerting?

Often in such cases the cause are different values. In our experiences, the Windows Taskmanager does not query WMI Classes to show its values. Can you please use our WMI Tester and scan against this particular target with the following query, and take a look at the result you get:

SELECT percentusage FROM Win32_PerfFormattedData_PerfOS_PagingFile WHERE Name='_Total'

This actually is the query that is also used by PRTG. As you can see in the query, PRTG is directly reading a percentage value from the target. So there is not much calculation done "by us" in this sensor.

best regards.
