Statistics Channels can't support alarms (ALH) #4

Closed ralphlange closed 6 years ago

ralphlange commented 8 years ago

Original LaunchPad bug #1404310 reported by Ralph Lange on 2014-12-19:

From Andrew (@anjohnson) :

Apparently pointing ALH to the stats channel of a gateway results in an ALH crash. Dirk Zimoch has more details...

It would be nice to be able to configure the gateway stats channels to generate alarms when the rates get too large, where the limits are configurable somehow.

Created from Mantis issue 355

This is not going to happen. It involves a fair amount of coding and testing work, and eventually would add IOC database functionality to a non-database application.

The existing workaround is easy and robust: Run a soft IOC with input records for the gateway stats channels you want to fully integrate, pointing their INP links to the gateway. This will add configurable alarms, alarm acknowledgement, description, simulation mode, etc. etc. at little cost.

Closing as wontfix.
