DESCRIPTION
The term event channel describes any facility used to publish or retrieve event information. It might refer
to any of the following:
• A simple log file
• An event management system
• A program that runs in order to obtain a snapshot of status information
The EVM channel configuration file, evmchannel.conf
, defines the available event channels and the
functions that operate on them. The file is read by:
• The EVM channel manager,
/usr/sbin/evmchmgr
, to identify the available channels, and to
determine when to run monitoring and cleanup functions.
• The
evmshow command, when it is invoked with the -d or -x option, to identify the channel to
which each event belongs, and the program that must be run to produce a detailed view or an
explanation of the event
• The
evmget server program, /usr/sbin/evmget_srv
, to identify the available channels and
their event retrieval functions
Refer to the evmchmgr(1M), evmshow(1), and evmget(1) manpages for more information.
The channel configuration file is a text file containing keyword/value or keyword/group pairs. Values con-
taining spaces must be enclosed in double quotes.
Any portion of a line from an unquoted number sign (
#) to the end of line is a comment. Blank lines are
ignored.
The following keywords are recognized:
path ch_path
The ch_path variable specifies a default directory containing executable programs that perform
the various channel functions. This path may be overridden by a ch_path variable specified for
an individual event channel. The syntax for a global path and a channel specific path are the
same.
cleanup_time [[hh:]mm:]ss
The time of day when the EVM channel manager executes the channel cleanup function,
specified by the fn_cleanup keyword, for each channel. If no cleanup time is specified, the
default is 2:00 a.m. local time. For example, cleanup_time 02:00:00. The channel
manager executes cleanup functions sequentially.
channel The channel keyword introduces a channel definition. The configuration keywords and
values for each channel must be enclosed in braces. There is no limit to the number of channel
definitions that can be included in the file.
