Web Performance Monitor and IE 10 / 11

I've had to deal with this myself,  My VM nodes have limited drive space and I was frequently running out and monitoring would stop until it was cleared.

It's not ideal, but for now, I've implemented a powershell job to run nightly on the players that stops the service, clears out the web cache files and then restarts the service. 

Unfortunately, due to this, we do lose monitoring for a bit of time while the job is running.

Example powershell script (I'm not a powershell scripter, so have no doubt this could be better)

Stop-Service -displayname "SolarWinds WPM Playback Player" 
Start-Sleep -s 10
Stop-Process -Name dllhost* -Force
Start-Sleep -s 10
Remove-Item C:\Users\SEUM-User-1\AppData\Local\Microsoft\Windows\WebCache\WebCacheV01.dat
Remove-Item C:\Users\SEUM-User-2\AppData\Local\Microsoft\Windows\WebCache\WebCacheV01.dat
Remove-Item C:\Users\SEUM-User-3\AppData\Local\Microsoft\Windows\WebCache\WebCacheV01.dat
Remove-Item C:\Users\SEUM-User-4\AppData\Local\Microsoft\Windows\WebCache\WebCacheV01.dat
Remove-Item C:\Users\SEUM-User-5\AppData\Local\Microsoft\Windows\WebCache\WebCacheV01.dat
Remove-Item C:\Users\SEUM-User-6\AppData\Local\Microsoft\Windows\WebCache\WebCacheV01.dat
Remove-Item C:\Users\SEUM-User-7\AppData\Local\Microsoft\Windows\WebCache\WebCacheV01.dat
Start-Service -displayname "SolarWinds WPM Playback Player" 

We have also experienced this problem, and due to this we have not been able to upgrade IE on our players past 9.

The powershell script is nice, but SolarWinds really needs to work with Microsoft to find a permanent fix for this. Hopefully we can get a reply from them on this soon..

Was there ever a resolution from SolarWinds on this?  We are having the same issue.

Thanks for the powershell!  We may be trying that out.  I created a feature request for them to fix this: http://thwack.solarwinds.com/ideas/3789

I went ahead and paid to opened a support case with Microsoft to try to work on this issue (as the issue is essentially the lack of ability to control the size of this WebCacheV01.dat file). They basically told me that there is absolutely no way to control the size of this cache. You'd think that they would provide a way to control this via a local policy or at least in IE being that Microsoft is all about granular control in products such as Group Policy.

I ended up coming up with a solution that works pretty well. If you deny each user permissions to their own Webcache folder, the browser simply doesn't write to cache. I left the player running like this with 250+ transactions for a few weeks without any trouble (transactions going unknown, etc). All you need to do is run the below script once after the player builds all user accounts. This way you don't need to keep running scripts to clean the cache.

icacls "C:\Users\SEUM-User-1\appdata\Local\Microsoft\Windows\WebCache" /deny "SEUM-User-1":(f) /t /c

icacls "C:\Users\SEUM-User-2\appdata\Local\Microsoft\Windows\WebCache" /deny "SEUM-User-2":(f) /t /c

icacls "C:\Users\SEUM-User-3\appdata\Local\Microsoft\Windows\WebCache" /deny "SEUM-User-3":(f) /t /c

icacls "C:\Users\SEUM-User-4\appdata\Local\Microsoft\Windows\WebCache" /deny "SEUM-User-4":(f) /t /c

icacls "C:\Users\SEUM-User-5\appdata\Local\Microsoft\Windows\WebCache" /deny "SEUM-User-5":(f) /t /c

icacls "C:\Users\SEUM-User-6\appdata\Local\Microsoft\Windows\WebCache" /deny "SEUM-User-6":(f) /t /c

icacls "C:\Users\SEUM-User-7\appdata\Local\Microsoft\Windows\WebCache" /deny "SEUM-User-7":(f) /t /c

Hopefully this can be of use.

Thanks,

Hi everyone,

It appears that this issue is resolved with the latest version of WPM.

I am not having the Webcache grow anymore since the upgrade.

Thanks Devs!

Sincerely,

Jason
