Database Filters

Hello:

Can you explain exact functionality of Database filters? The way I understand is that it will filter out events before they are stored in Database however it cannot filter incoming events, let me know exact operation.

One issue, I faced was that when I created database filter for filtering out unwanted events and click on "apply" all the servers/devices showed "Orange" status and stopped collecting logs. I then deleted the filter and restarted the EventLog Service and then servers started collecting logs again.

Kindly let us know right procedure and also whether Unix Host and Windows Host group filters should be separate?

Thanks/Lilish
