Earthworm Module: ewthresh

Contributed by:

Function

Monitors a ring for TRACEBUF2X messages and generates an alarm message when a SCNL-specific threshold is exceeded.

Details

The ewthresh module monitors a ring for TRACEBUF2X messages. If a message's maximum (converted) value exceeds the threshold specified for that message's SCNL, an alarm message is written to the output ring identifying the SCNL, threshold, time, and maximum (converted) value.

The primary option is what SCNLs to monitor and what threshold to use for it.

                                    # if 2, write to module log but not to
                                    # stderr/stdout
