What is the policy that describes how many messages to display or which time interval? How can I customize it?
The following information is documented in the Agent Builder manual only, but it is valid for the SOA/DP agent too.
The default workspace will display the current data that are query from the cache. There is an environment variable to control how many records to be cached in memory.
CDP_PURE_EVENT_CACHE_SIZE. The default number is 100 records.
"The maximum number of events to cache when a log file data source is configured to process new records. Each new record in the log will cause an event to be sent. This environment variable defines how many events are remembered in a cache by the agent. The cached values are returned when the attribute group is queried."
So, if your environment has many records that are not of LATENCY category in the log file, then you can either modify the variable to assign a bigger value, or the normal way is to enable the history collection on this attribute group and to display data for a specific time frame by changing the time span on the workspace.
