Tuning Performance
❏ Managed Nodes
Improve processing performance on the managed nodes:
Heartbeat Polling Interval
Increase the heartbeat polling interval for the managed node
activity check.
Message Text
Use message text match conditions with the case-sensitive check
as often as possible. This flag can be set in several places,
including the Advanced Options window of the
Add/Modify/Copy Logfile window.
Message and Suppress Conditions
Change the sequence of the message and suppress conditions so
that the messages most frequently required are near the top of
the list. This change prevents wasted processing of conditions
that cannot find a match to a logfile. (Message and Suppress
Conditions window.)
Logfile Polling Interval
Set the polling interval for logfile (Modify Logfile window) and
threshold monitoring (Modify Monitor window) as high as
possible, while ensuring that they adequate data.
Message Buffer
Set a limit for the message buffer file in the Node
Communication Options window (Actions: Node -> Add ->
Communication Options). This limit ensures that the file does
not grow unchecked and fill the disk if the management server
becomes temporarily unavailable. The message agent counts the
number of discarded messages, started actions, and message
operations like acknowledge requests, and forwards them when
the server becomes available again.
NOTE Because the message agent and the action agents use different
mechanisms, some action requests attributed to the final
messages buffered in the file may not be executed. It is therefore
likely that the message buffer file will contain more messages
than action responses.
