evminfo - Provides information about EVM
evminfo -lc | -vp | -verify verify_option [-file verify_file]
-lc 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.
-vp 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 sys-
tem 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.
The evminfo command writes selected information about the EVM environment
to its standard out stream. The options determine the information to be
The following exit values are returned:
0 Successful completion.
An error occurred.
1. 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
$ evminfo -lc
$ evmget -A -C misclog,evmlog
2. This example illustrates the use of evminfo -vp in a shell script to
determine the first two components (by convention, the vendor and pro-
duct components) of the names of system events in the host system. The
script then uses evmwatch to monitor system events.
evmwatch -f "[name $VP]" | evmshow
