<p class="MsoNormal">I have recently set up a new Xymon (<b><span style="font-size:7.5pt;font-family:"Arial",sans-serif;color:silver"><a href="http://xymon.sourceforge.net/"><span style="text-decoration:none">Xymon 4.3.28-1.el6.terabithia</span></a></span></b>)
server on RHEL 6.7 that, for the most part, is doing just fine. However, I’ve discovered that my /var/log/xymon/alert.log file is growing at a crazy rate to the point it periodically needs to zero’d-out or it will swamp the file system.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The problem is every 15 seconds the /var/log/xymon/alert.log file receives a flurry of log entries like this:<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The '0FS_96_192_168_22_1__export_’ is actually the name of a host I’ve defined in the past, but is no longer in xymon’s memory (AFAIK!!)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have reduced the alerts.cfg down to a minimal stub, commenting out the “directory /etc/xymon/alerts.d/…” directive, “rm –r”’d any reference to this host (and others similar to it) under the data files directories (e.g. rrd/, hist/, histlogs/,
hostdata/, etc.).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have gone as far as running “find /etc/xymon –type f | xargs egrep 0FS_” looking for “surprises”. I’ve also stopped / restarted the server and scanned what’s active in memory via “xymon localhost xymondboard | egrep 0FS_”.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This “host” is not a real client host but an artifact I’ve created on the server side to represent a file system I’m monitoring in a server-side ext script, so I know it is not announcing it’s presence over port 1984. For the life of me
I can’t figure out where the alerts daemon is running across this hostname.<o:p></o:p></p>
