To make informed decisions when you select metrics, review these points to understand CA Server Automation performance and application metrics collection:
Install CA Systems Performance LiteAgent or the SystemEDGE agent on any server from which you want to collect the base system metrics. If SystemEDGE agents are present, then the CA Systems Performance LiteAgent is not required. If necessary, you can install the SystemEDGE agent using the product user interface. All performance metrics are stored in the Performance DB.
Note: Select Include for Overall Calculation in the Policy, Metrics, Thresholds section of the user interface to include new metric in the overall utilization calculation. If you include the metric, CA Server Automation provides up-to-date results when evaluating the state of the servers.
What are the default metrics? The default metric definitions are located in the metric list in the Filter section for all supported platforms. You can find the default metrics indicator on the metric list with the value Yes in the Default column. CA Server Automation uses this list to obtain the metric definitions when you add a server. You can configure platforms, types, subtypes, instances, and the type of data to collect in the Filter section. The metric filter and definitions for each server are stored in the Performance DB.
<property name="CONFIG_KEY_DEFAULT_HEALTH_STATE"> <!-- Valid values: 0 (Unknown); 5 (OK); 10 (Warning); 15 (Minor Failure); 20 (Major Failure); 25 (CriticalFailure) --> <!-- Changes the value of HealthState for the CA_CollectionState object associated to the CA_ComputerSystem --> <!-- If set to 30, CE will not set the HealthState. --> <value>5</value> <displayName>Default node health state when problem encountered in metric or data collection</displayName> </property
CA Server Automation modifies the value surrounded by the value XML elements to one of the other supported values such as 5 or 10, for OK or Warning respectively. These changes reflect the desired state when performance data cannot be collected. For example:
<property name="CONFIG_KEY_DEFAULT_HEALTH_STATE"> <!-- Valid values: 0 (Unknown); 5 (OK); 10 (Warning); 15 (Minor Failure); 20 (Major Failure); 25 (CriticalFailure) --> <!-- Changes the value of HealthState for the CA_CollectionState object associated to the CA_ComputerSystem --> <!-- If set to 30, CE will not set the HealthState. --> <value>10</value> <displayName>Default node health state when problem encountered in metric or data collection</displayName> </property
Because <value> was changed to "10", systems that do not have performance data available are displayed in a warning state in the CA Server Automation user interface.
Note: For a list of performance metrics and descriptions, see the Reference Guide.
