NAME

  evminfo - Provides information about EVM

SYNOPSIS

  evminfo -lc  | -vp  |	-verify	verify_option [-file verify_file]

OPTIONS

  -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.

  -verify verify_option
	      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	information to be
  displayed.

EXIT STATUS

  The following	exit values are	returned:

  0   Successful completion.

  not 0
      An error occurred.









EXAMPLES

   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
       channels.
	    $ evminfo -lc
	    syslog
	    binlog
	    misclog
	    evmlog
	    $ 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.
	    VP=`evminfo	-vp`
	    evmwatch -f	"[name $VP]" | evmshow

   3.  The following example checks the	syntax of the EVM daemon configura-
       tion file.
	    evminfo -verify daemon
