The
Event Manager channel manager, evmchmgr, provides
log management capability through the channel fn_cleanup function.
You can define this capability for any channel through the channel configuration
file, evmchannel.conf. For more information on
this file, see “Configuring Event
Manager Channel” .
By default, channel cleanup functions run when Event Manager
starts, and then run at 2:00 am each day. You can change the time
of day by editing the cleanup_time value in the
channel configuration file. When a cleanup is scheduled, the channel
manager scans the event channel list, and executes the fn_cleanup command
for each channel identified in the file.
The evmlog cleanup function, evmlog_cleanup,
accepts the following arguments:
The
archive period, which has a default value of 7 days.
The delete period, which has a default value of
31 days.
The function uses the find utility to locate
and compress (zip) all logs older than the archive period, and to
delete any archived files older than the delete period. You can
change the period values by editing the function definition in the
channel configuration file. Setting either of these values to zero
disables the corresponding function.
The evmget command
does not retrieve evmlog events that are stored
in archived (zipped) logs. To retrieve events from archived logs,
you must first uncompress them with the gunzip command.
For information on unzipping archive files, see gunzip(1).
