Monitoring RDS Function and Performance

RDS Log Files

The RDS service logs various events in a special log file in the server working directory. The file is <SWD>/logs/rds.log. Log entries have verbosity levels associated with them: (4=info (default) ). To control the level of logging in the rds.log file, specify the desired maximum message log level in the LOG_LEVEL variable in resources.cfg. The log levels are defined as follows:


Level	Log Level Number
Fatal	1
Error	2
Warning	3
Info	4 (default)
Verbose	5
Debug	6
Internal	7

Inner Loop Timers

The vovserver tracks how the time is spent in the inner loop. The statistics are accumulated over multiple loops and are rotated every 10 seconds, so what you normally see in the stats is the overall time spent in the past 10 to 20 seconds. With RDS a new timing category "rds" is added.

If you are ADMIN, you can check the timers with vovshow:

% nc cmd vovshow -innerlooptimers
