Recommended practices for filtering

PATROL for Entuity Server can filter the data displayed, but the data of all the devices monitored by the Entuity server is transferred to the application via the PATROL Agent.

In order to reduce the amount of data traffic. BMC recommends that you create a view for each Entuity server accounts with access privileges to those sub-sets of the network that you want to monitor. This will reduce the flow of traffic between the Entuity server and the PATROL Agent.

You can use the filtering capabilities of PATROL for Entuity Server to perform sophisticated filtering actions. The following examples are intended to highlight the possibilities that this product makes available to you.
