Thanks for everyone's responses. So far, the evntwin.exe has fit the
bill perfectly. It can turn almost any event log entry into an snmp
trap (which can be manipulated thru event customization or rulesets)
and, so far, has provided very fast notification - at least as reliable
as testing can be.

I realize this is a non netview solution but as an alternative
suggestion is to use TecWin adapter to scrape the NTEVENT log, and post
the message to TEC. This bypasses netview polling and provides a close
to real time alert, and less burden on the netview server.

This is getting a little off the original topic, but I have used servmon
successfully to monitor by means other than port sniffing.
Don't forget that servmon can either be told to "sniff" a port or ports,
OR, you can provide him with a script that discovers a "service" and a
script that does status checking on a "service". So, if you are trying
to detect whether application xyz exists and is running, you can write a
script that does something like:
ps -ef | grep xyz | grep -v grep (the grep -v grep
just avoids getting a match for your grep process).
So far, so good - but the glitch is that the discovery and status
scripts that servmon runs, run on the NetView server itself, not on
boxes out in the network.
The solution I built was based on the fact that the boxes to be
monitored for the xyz process, had ssh installed and setup, as did the
NetView system. I created a userid on the systems, called servmon, and
made sure that ssh worked between the NetView system and my target
systems. Then, the script that servmon runs is similar to my one-liner
above but you run it as a parameter to ssh. Here's my sample code (I
will put it on the NetView TUG site):
#!/bin/bash
# Script to be run from servmon to check for a particular process #
Script uses ssh to check remote systems - it is assumed that ssh works #
# The first parameter should be node to check for a particular process #
The second parameter is the process to check for # # Return codes are 2
= Normal 4 = Critical 0 = test cannot be run # #set -x #echo start
`date` >> /tmp/set #set >> /tmp/set
RET_CODE=4
USERID="servmon"
HOST="$1"
PROCESS="$2"
COMMAND="ps -ef | grep $PROCESS | grep -v grep"
# Parameters for ssh command - -f puts ssh in background; -n redirects
stdin from /dev/null #echo "/usr/bin/ssh -f -n -F
/home/$USERID/.ssh/config -i /home/$USERID/.ssh/identity -i
#/home/$USERID/.ssh/id_rsa -i /home/$USERID/.ssh/id_dsa $USERID@$HOST
$COMMAND" >> /tmp/set
# Note next 2 lines should be all on one line RESULT=`/usr/bin/ssh -f -n
-F /home/$USERID/.ssh/config -i /home/$USERID/.ssh/identity -i
/home/$USERID/.ssh/id_rsa -i /home/$USERID/.ssh/id_dsa $USERID@$HOST
$COMMAND`
#echo result is $RESULT >> /tmp/set
if [ "$RESULT" = "" ]
then echo $RESULT; exit 4
else echo $RESULT; exit 2
fi
The hard part is ensuring your ssh is good. Once that works, the rest
is a doddle. Of cource, if you are not so security conscious, you might
just use rexec if you have that, rather than ssh.
Cheers,
Jane
