Operational alerts custom properties


You can use the operational alerts custom properties to improve the performance of the operational alerts on your runtime reporting and operational summary pages.

You can tune the performance of your operational alerts by setting any of the following custom properties on the cell. Set the properties that you want to a value that is different from the default value. To set the operational alerts custom properties on the cell:

  1. In the administrative console, click System administration > Cell > Custom properties > New.

  2. Type the name of the custom property in the format, opalert.property_name, for example, opalert.disableCache.

  3. Indicate a value for the custom property. Use the possible values in the following list of custom properties to determine the value that you use.

  4. Save the custom property. The custom property is retrieved dynamically. You do not need to restart the deployment manager. The custom property is set for all the resources in the cell.
To set a custom property on a specific resource:

  1. In the administrative console, click System administration > Cell > Custom properties > New.

  2. Type the name of the custom property in the format, opalert.resource_typeproperty_name. The resource_type value is the name of the core group or core component on which you want to set the property. Use the name for the core component or core group that is listed in the administrative console. For example, you might use the name, opalert.ARFMController.disableCache, to set the property on the autonomic request flow manager (ARFM).

  3. Indicate a value for the custom property. Use the possible values in the following list of custom properties to determine the value that you use.

  4. Save the custom property. The custom property is retrieved dynamically. You do not need to restart the deployment manager. The custom property is used only for the resource that you indicated.

opalert.disableCache

When set to true, this custom property disables caching, which also disables any performance gains. You can use this custom property when you are debugging.

Value true or false
Default false
opalert.disableAlerts

When set to true, this custom property disables the cacheable providers from adding operational alerts. To view detailed information about items such as core groups and core components, go to the operations view that is specific to the core group or core component.

Value true or false
Default false
opalert.disableXDStability

When set to true, this custom property disables the cacheable provider from contributing to the overall status. To view detailed information about items such as core groups and core components, go to the operations view that is specific to the core group or core component.

Value true or false
Default false
opalert.initPolicy

This custom property determines if the request waits for the initialization of the cache to complete before returning a status message. The first request for the information causes caching to occur. If the initialization policy is set to blocking, the initialization of the cache must complete before returning a status message. If the initialization policy is set to nonblocking, then an UNKNOWN status message is returned. You can refresh the operational alerts page or operations view when the cache has finished initializing. This property is only used when the cache initializes.

Value blocking or nonblocking
Default nonblocking
opalert.disableAutoRefresh

By default, the caches are automatically refreshed on a time interval. If this property is set to true, the caches are not automatically refreshed, and do not refresh until a new request comes in after the caches have been destroyed.

Value true or false
Default false
opalert.initPeriod

If the opalert.disableAutoRefresh property is enabled, this custom property defines how long to wait after an initialization is completed to start initialization again.

Value Integer, in seconds
Default 10 seconds
opalert.destPolicy

The destruction policy specifies when to destroy the provider caches.

  • Specify inactivity to destroy the caches if the cache is not accessed for the amount of time that is specified in the opalert.destPeriod custom property.

  • Specify fixedTimeout to destroy the cache after the amount of time that is specified in the opalert.destPeriod custom property passes after the first initialization period. This value does not consider when the last cache access time is. If you have the opalert.disableAutoRefresh enabled, consider setting this custom property to fixedTimeout.
Value inactivity or fixedTimeout
Default inactivty
opalert.destPeriod

This custom property specifies the destruction period in seconds. The destruction period works with the opalert.destPolicy custom property to determine how long to wait, either after the first initialization or the last access, before destroying the cache.

Value seconds
Default 600 seconds (10 minutes)
