PMDF System Manager's Guide

An option file may be used to specify alarm thresholds for stored message counts. These thresholds may be used by intelligent monitoring clients to determine when a channel has suspiciously too many stored (i.e., queued) messages. The sample monitoring configuration described in Section 31.7.1 uses these thresholds for the JavaScript enhanced monitoring.

The option file is called PMDF_TABLE:monitor_option. (OpenVMS) or /pmdf/table/monitor_option (UNIX) or C:\pmdf\table\monitor_option (NT).

By default, the threshold level is 1500 messages; that is, the value reported for the %counter_stored_messages_threshold is 1500, by default. To specify a different default threshold level, in the option file specify

STORED_THRESHOLD=value

where value is the desired value. To set a threshold for a specific channel, specify the option

channel-name_STORED_THRESHOLD=value

where channel-name is the name of the channel for which to set the threshold.

The sample option file shown below, sets a default threshold of 200 messages and thresholds of 500 messages for the local and tcp_local channels:

STORED_THRESHOLD=200 L_STORED_THRESHOLD=500 TCP_LOCAL_STORED_THRESHOLD=500
