Once the forward progress counter again begins incrementing, the operational state will return to enabled. +**Application Monitoring with AllSeemsWell** + + The IntegrityMonitor class provides a facility for applications to directly control updates of the forwardprogressentity table. As previously described, *startTransaction()* and *endTransaction()* are provided to monitor the forward progress of transactions. This, however, does not monitor things such as internal threads that may be blocked or die. An example is the feature-state-management *DroolsPdpElectionHandler.run()* method. + + The *run()* method is monitored by a timer task, *checkWaitTimer()*. If the *run()* method is stalled an extended period of time, the *checkWaitTimer()* method will call *StateManagementFeature.allSeemsWell(<className>, <AllSeemsWell State>, <String message>)* with the AllSeemsWell state of Boolean.FALSE. + + The IntegrityMonitor instance owned by StateManagementFeature will then store an entry in the allSeemsWellMap and block updates of the forwardprogressentity table. This in turn, will cause the Drools PDP operational state to be set to “disabled” and availability status to be set to “failed”. + + Once the blocking condition is cleared, the *checkWaiTimer()* will again call the *allSeemsWell()* method and include an AllSeemsWell state of Boolean.True. This will cause the IntegrityMonitor to remove the entry for that className from the allSeemsWellMap and allow updating of the forwardprogressentity table, so long as there are no other entries in the map. + **Dependency Monitoring** When a Drools PDP (or other node using the *IntegrityMonitor* policy/common module) is dependent upon other nodes to perform its function, those other nodes can be defined as dependencies in the properties file. In order for the dependency algorithm to function, the other nodes must also be running the *IntegrityMonitor*. Periodically the Drools PDP will check the state of dependencies. If all of a node type have failed, the Drools PDP will declare that it can no longer function and change the operational state to disabled and the availability status to dependency. diff --git a/docs/platform/index.rst b/docs/platform/index.rst index 4baf57e90..3dca9ec16 100644 --- a/docs/platform/index.rst +++ b/docs/platform/index.rst @@ -20,6 +20,7 @@ Policy Installation and Deployment installationVM.rst installAmsterController.rst installBeijingController.rst + swarch_srm.rst deployment.rst Policy Software Architecture @@ -28,7 +29,6 @@ Policy Software Architecture .. toctree:: :maxdepth: 1 - swarch_srm.rst swarch_pdp.rst feature_eelf.rst feature_testtransaction.rst diff --git a/docs/platform/srmPdpxPdpMgmt.png b/docs/platform/srmPdpxPdpMgmt.png Binary files differindex 5a998f080..69360f470 100644 --- a/docs/platform/srmPdpxPdpMgmt.png +++ b/docs/platform/srmPdpxPdpMgmt.png diff --git a/docs/platform/srmPdpxResiliencyPdpMgmt1.png b/docs/platform/srmPdpxResiliencyPdpMgmt1.png Binary files differindex 84d468fe3..50b3ee86e 100644 --- a/docs/platform/srmPdpxResiliencyPdpMgmt1.png +++ b/docs/platform/srmPdpxResiliencyPdpMgmt1.png diff --git a/docs/platform/srmPdpxResiliencyPdpMgmt2.png b/docs/platform/srmPdpxResiliencyPdpMgmt2.png Binary files differindex 6b5ae8510..46721f3ae 100644 --- a/docs/platform/srmPdpxResiliencyPdpMgmt2.png +++ b/docs/platform/srmPdpxResiliencyPdpMgmt2.png diff --git a/docs/platform/srmPdpxScalingPdpMgmt1.png b/docs/platform/srmPdpxScalingPdpMgmt1.png Binary files differnew file mode 100644 index 000000000..f04cbee4f --- /dev/null +++ b/docs/platform/srmPdpxScalingPdpMgmt1.png diff --git a/docs/platform/swarch_srm.rst b/docs/platform/swarch_srm.rst index 2de6baebc..1483eb24e 100644 --- a/docs/platform/swarch_srm.rst +++ b/docs/platform/swarch_srm.rst @@ -2,14 +2,14 @@ ..
