Fixed In:

Opened: Aug 11, 2016
Severity: 3-Major

Symptoms

The link throughput performance graphs available in the GTM, DNS or Link Controller modules might show the throughput for the wrong link in the graph.

Impact

The graphs for all links that contain the prefix might show the throughput for the link whose name matches the prefix. For example, the throughput graphs for both "mylink" and "mylink2" might both show the throughput data for "mylink" As a result of this issue, the historical link throughput data is gathered and stored incorrectly. This data is used to generate the throughput graphs.

Conditions

Multiple links exist and one of the links has a name that is a prefix for the name of one or more other links. For example, there are two links defined and named "mylink" and "mylink2".

Workaround

Do not create links where the name of one link forms a prefix for the name of other links.

Fix Information

Link throughput graphs now collect and show the throughput for the proper link when one link name is a prefix of one or more other links. Note that historical information gathered before the fix will not be corrected.
