You can use the high availability manager counters that the Performance Monitoring Infrastructure (PMI) and Tivoli Performance Viewer (TPV) collect to monitor activity within your high availability environment.
Name | Key | Description | Granularity | Type | Level | Overhead |
Number of local groups | hamanagermodule.numLocalGroups | The total number of local groups. | Per server | RangeStatistic | All | High |
Group state rebuild time | hamanagermodule.rebuildTime | Time taken in milliseconds to rebuild the global group
state. During the rebuild time, no fail-over can happen. If this time is too
high and is unacceptable for the desired availability, you may want to increase
the number of coordinators. For proper operation of this counter, you must host the active coordinator in an application server other than the deployment manager. |
Per server | TimeStatistic | All | High |
Number of bulletin-board subjects | hamanagermodule.bbMgrNumSubjects | The total number of subjects managed. | Per server | RangeStatistic | All | High |
Number of bulletin-board subscriptions | hamanagermodule.bbMgrNumSubscriptions | The total number of bulletin-board subscriptions. | Per server | RangeStatistic | All | High |
Bulletin-board rebuild time | hamanagermodule.bbMgrRebuildTime | Time taken in milliseconds to rebuild the global state
of the bulletin-board. During this time no messages will be received by the
subscribers. If this time is too high, and is unacceptable, you may want to
increase the number of coordinators. For proper operation of this counter, you must host the active coordinator in an application server other than the deployment manager. |
Per server | TimeStatistic | All | High |
Number of local bulletin-board subjects | hamanagermodule.bbLocalNumSubjects | The total number of subjects being posted to locally. The number includes the proxy postings (if any) done by the core group bridge service on behalf of servers belonging to different WebSphere cells. | Per server | RangeStatistic | All | High |
Number of local bulletin-board subscriptions | hamanagermodule.bbLocalNumSubscriptions | The total number of local subject subscriptions. The number includes the proxy subscriptions (if any) done by the core group bridge service on behalf of servers belonging to different WebSphere cells. | Per server | TimeStatistic | All | High |
