Measurement Group: ComAgent Exception
Measurement Type: Simple
Measurement Dimension: Arrayed (by Resource ID)
Description: Number of stack events discarded because they were submitted to an Unavailable Sub-Resource of a given Resource. During normal operation, this measurement should not be increasing. Each count of this measurement indicates that a local application attempted to send a stack event to another server using an HA Service Sub-Resource, but the event was discarded due to the Sub-Resource being unavailable.
Collection Interval: 30 min
Peg Condition: Stack event submitted to ComAgent by a local User Layer, and the stack event references an Unavailable Sub-Resource.
Measurement Scope: Server
Recovery:
If a discarded stack event was a request from a reliable transaction and the routing failure was due to a temporary condition, then it is possible that the transaction completed successfully using one or more retransmit attempts.
This measurement may not indicate an error if the discarded stack event was a reliable request, the Reliable Transfer Function was able to re-attempt, and the subsequent attempt got through.
