IOC Statistics

The CPU Load Average starts a warning above 50% and alarm above
80%. The Maximum Free Memory (Largest Free Block) triggers a warning
below 500,000 bytes and an alarm below 100,000 bytes. The warning for
Channel Access (CA) Clients triggers at 100 and alarms at 175. The
warning for Channel Access (CA) Connections starts at 1000 and turns
into an alarm at 1750. Our experience shows that we can load a 16MB
MV177 CPU with about 8000 CA connections and 30 CA Clients before it
dies. When free File Descriptors (FD) drops below 20 the warnings
starts and at 5 an alarm is signaled. These readings are scanned at
around 15 second intervals.

All the settings are user defined in the ioc.tmpl file. CEN-MON has a
different IOC alarm levels based on our experiences. The channel
access connection's warning was moved to 5000 and alarm to 7000. The
channel access clients were moved down to 25 for the warning and 30
for the alarm.
