### 5. Adding New Queries to Existing Owl Sensors

From time to time, you might decide to change the queries being performed by the Owl sensors. This could be adding new queries to some or all of the sensors, stopping some of the queries from being performed, or modifying existing queries. Regardless of the changes, there are actions that must be taken on the Owl manager and all affected Owl sensors.

It is relatively painless to modify queries for a sensor. The following actions must be performed:

1. The query entries in the Owl configuration file must be changed to reflect the new set of queries that should be performed. Add new query entries to add new queries; delete or change existing query entries to remove or modify current queries. See section 4.4 for information about query entries.

2. Restart owl-dnstimer.

If you have correctly set up your configuration file, then owl-dnstimer will start collecting data for the new queries.

Stopping collection of certain queries only requires deleting (or commenting out) the appropriate entries from the configuration file. owl-dnstimer, of course, must be restarted.
