<p class="MsoNormal">Johan, <o:p></o:p></p>
<p class="MsoNormal"><span lang="EN-US">Hi.</span><o:p></o:p></p>
<p class="MsoNormal"><span lang="EN-US">We have a syslog server which receives logs from a number of servers and network devices.</span><o:p></o:p></p>
<p class="MsoNormal"><span lang="EN-US">Currently we use the log test in Xymon to check for errors in these logs, and it works fine. But it is a little blunt since all log test end up in the same msgs test. It could also be a problem if we get an error in one
log file, and need to ack or disable the test. In this case we would not get any alert if there were errors in one of the other logs.</span><o:p></o:p></p>
<p class="MsoNormal"><span lang="EN-US">It would have been nice if you could add a client definition to a logfile test in analysis.conf, and report each log file as the device which is originates from. Or maybe as a separate syslog test to distinguish it from
the msgs test.</span><o:p></o:p></p>
<p class="MsoNormal"><span lang="EN-US">This way we could also set up individual alerts for the different logged devices.</span><o:p></o:p></p>
<p class="MsoNormal"><span lang="EN-US">I could, of course, write a client- or serverside script for this, but I always find it difficult to do good log monitoring scripts and it would be nice to be able to use the logic already in Xymon</span><o:p></o:p></p>
<p class="MsoNormal"><span lang="EN-US"> </span><o:p></o:p></p>
<p class="MsoNormal"><span lang="EN-US">What do you think? Would anyone else be interested in this feature? I also have no idea how much work it would be.</span><o:p></o:p></p>
<p class="MsoNormal"><span lang="EN-US"> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Times New Roman","serif";mso-fareast-language:SV">I have also been looking at this same problem just recently.<br>
<br>
My log structure is keyed by IP address with daily files - e.g. /var/log/rsyslog/IP/messages-YYYMMDD - how the files are set up would need to be accommodated.<br>
<br>
I've thought of 2 approaches:<br>
* writing a utility from scratch to examine the log files - however this then requires all the message rules to be reimplemented rather than using analysis.cfg<br>
* writing a utility that uses 'logfetch' (xymon client utility) to grab relevant section of logfile and then send a client message (still need to work out what class and other details to include in the header) on behalf of the device which contains [msgs:/var/log/messages]
section for the log file. With this approach, if the client has no other client message reporting we're OK, but if not, I'm not sure if it will cause problems also. Mostly I'd be looking at this for switches/firewalls/etc so no direct client report in place.<br>
