Intelligent Management: operational alerts custom properties
Use the operational alerts custom properties to improve the performance of the operational alerts on your runtime reporting and operational summary pages.
We can tune the performance of our operational alerts by setting any of the following custom properties on the cell. Set the properties to a value that is different from the default value.
To set the operational alerts custom properties on the cell:
- In the administrative console, click...
System administration > Cell > Custom properties > New
- Type the name of the custom property in the format, opalert.property_name, for example, opalert.disableCache
- Indicate a value for the custom property. Use the possible values in the following list of custom properties to determine the value that we use.
- Save the custom property.
The custom property is retrieved dynamically. We 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:
- In the administrative console, click...
System administration > Cell > Custom properties > New
- 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 to set the property. Use the name for the core component or core group listed in the administrative console. For example, we might use the name, opalert.ARFMController.disableCache, to set the property on the autonomic request flow manager (ARFM).
- Indicate a value for the custom property.
Use the possible values in the following list of custom properties to determine the value that we use.
- Save the custom property.
The custom property is retrieved dynamically. We do not need to restart the deployment manager. The custom property is used only for the resource that you indicated.
opalert.disableCache
When true, disable caching, which also disables any performance gains. We can use this custom property when we are debugging.
Value Description Value True or false Default false
opalert.disableAlerts
When true, disable 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 Description Value True or false Default false
opalert.disableXDStability
When true, disable 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 Description 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. We 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 Description Value blocking or nonblocking Default nonblocking
opalert.disableAutoRefresh
By default, the caches are automatically refreshed on a time interval. If 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 Description 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 Description 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 specified in the opalert.destPeriod custom property.
- Specify fixedTimeout to destroy the cache after the amount of time 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 we have the opalert.disableAutoRefresh enabled, consider setting this custom property to fixedTimeout.
Value Description Value inactivity or fixedTimeout Default inactivty
opalert.destPeriod
Specify 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 Description Value seconds Default 600 seconds (10 minutes)
