Journal QoS policies

Quality of service (QoS) includes a journaling function. Journaling allows you to track QoS policy actions, such as when a policy was added, removed, or changed.

Journaling creates a log of policy actions as long as you have journaling set to on. This helps you to debug and spot check where policies are not operating as expected. For example, you set a policy to run from 9:00 a.m. to 4:00 p.m. You can check the journal log to see if the policy was actually added at 9:00 a.m. and removed at 4:00 p.m.

If journaling is turned on, journal entries are generated anytime a policy is added, removed, or modified. Using these journals, you create a general file on the iSeries™ server. You can then use the information recorded in your system's journals to determine how your system is being used. This can help you decide to change various aspects of your policies.

Be selective in what you choose to journal. Journaling can be a heavy burden on your system's resources. To start or stop journaling, you use iSeries Navigator. To view the journal logs, you must use the character-based interface.

To start or stop journaling, follow these steps:

In iSeries Navigator, expand your server > Network > IP Policies.
Right-click Quality of Service and select Configuration.
Right-click QoS and select Properties.
Select the Run Journaling box to turn journaling on.
Deselect the box to turn journaling off.

Note: If the server is already started before you complete the steps above, you must stop and restart the server. After journaling has been turned on, there are two ways to activate it. You can stop and restart the server or perform a server update. Either way will reread the policy.conf file and look for the journaling attribute.
