Setting SCOM console polling rate

It is known that having a number of consoles open slows down the SCOM environment. This is because, each console places a burden on the RMS server as all consoles (including web console sessions) connect to the SDK service on the RMS server.

So if you have more than a few consoles open continuously you might consider lowering the refresh rate of the consoles.

The registry key that controls this behavior is: “HKCU\Software\Microsoft\Microsoft Operations Manager\3.0\console\CacheParameters\ PollingInterval”

The values it accepts are in the range 0 – 10, where 0 turns off automatic refreshes and requires manual refresh via F5. The values 1 through 10 increment the refresh interval by 15 seconds.

PollingInterval	RefreshedEvery_Secs
1	15
2	30
3	45
4	60
5	75
6	90
7	105
8	120
9	135
10	150

Setting this property in powershell is easy

#check current setting
Get-ItemProperty -LiteralPath 'HKCU:\Software\Microsoft\Microsoft Operations Manager\3.0\Console\CacheParameters' -Name PollingInterval

#change current setting
Set-ItemProperty -LiteralPath 'HKCU:\Software\Microsoft\Microsoft Operations Manager\3.0\Console\CacheParameters' -Name PollingInterval -Value 5
