Managing APPN/HPR Resources › Check RTP Health

Check RTP Health

The RTP Health Check displays lists of RTP pipes that indicate the following network performance issues:

• ARB mode is RED and the condition has existed for more than five minutes
• An error pathswitch occurred in the most recent interval and more than one pathswitch occurred in the last three intervals
• RTPs are experiencing impaired throughput
• RTPs are currently in a stalled condition
• RTPs have congestion
• Retransmission percentage exceeds the specified threshold (default 5%)
• RTPs have significant queueing

RTPs are monitored using the SNA Network Management API using a five-minute interval. Each list is for a specific health check and an RTP may appear in more than one list.

The RTP Health Check can be performed on the local system or globally on all RTPs in a multisystem environment.

Example: RTP Health Check Error Pathswitches

Check RTP Health on a Local System

You can perform an RTP Health Check on a local system or a multisystem.

To check RTP health on a local system, enter /RTPH at the command prompt.

Check RTP Health on a Multisystem

You can perform an RTP Health Check on a local system or a multisystem.

To check RTP health on a multisystem, enter /RTPHG at the command prompt.

Define RTP Health Thresholds

To allow control over RTP health conditions, you can customize the following thresholds in the monitoring definition of the APPNHPR resource:

• Inbound Queue Depth
• Outbound Queue Depth
• Retransmission Rate

Note: The limits defined for the APPNHPR resource apply:

• To all health checks except for the EE resource health checks
• To the APPNHPR: RTP health check diagnostic displays

If there is no APPNHPR resource in the active system image, the default of 100 is applied to inbound and outbound queues, and the default of 5% is applied for retransmission rate.

To define RTP health thresholds

1. Enter /IPMON at the command prompt.

   The Resource Monitor appears.

2. Enter U beside the APPNHPR resource for which you want to update the thresholds.

   The Panel Display List appears.

3. Enter S beside APPNHPR Monitor Definition.

   The APPNHPR Monitoring Definition panel appears.

4. Complete the RTP Health Limits field.

   Note: For more information about the fields, press F1 (Help).

5. Press F3 (File).

   The details are saved.
