evminfo(1) General Commands Manual evminfo(1)
NAME
evminfo - Provides information about EVM
SYNOPSIS
evminfo -lc | -vp | -verify verify_option [-file verify_file]
OPTIONS
Reads the EVM channel configuration file, /etc/evmchannel.conf, and writes a list of all the configured event channels. You can review the
events available for retrieval through a particular set of channels by invoking evmget with the -C option. Writes a string that can be
used as the first two components (by convention the vendor and product components) of a system event name. This option enables script
writers to refer to system events in a way that is independent of the host system. You should use this facility if you are writing a
script that in the future may be used on other platforms that support EVM, and whose system events may have a different prefix. Checks the
syntax of the EVM configuration file specified by verify_option. Valid values for verify_option are daemon, logger or chmgr, to verify the
EVM daemon, EVM logger or EVM channel configuration files respectively. If a verify_file is specified the named file is checked instead of
the component's standard configuration file.
DESCRIPTION
The evminfo command writes selected information about the EVM environment to its standard out stream. The options determine the informa-
tion to be displayed.
EXAMPLES
In the following example, the evminfo -lc command lists the names of all event channels configured in the EVM channel configuration file,
and the user invokes evmget to retrieve events from two of the listed channels. $ evminfo -lc syslog binlog misclog evmlog $ evmget -A -C
misclog,evmlog
This example illustrates the use of evminfo -vp in a shell script to determine the first two components (by convention, the vendor and
product components) of the names of system events in the host system. The script then uses evmwatch to monitor system events. VP=`evminfo
-vp` evmwatch -f "[name $VP]" | evmshow
The following example checks the syntax of the EVM daemon configuration file. evminfo -verify daemon
EXIT VALUES
The following exit values are returned: Successful completion An error occurred
FILES
The EVM channel configuration file. The EVM daemon configuration file. The EVM logger configuration file.
