<p class="MsoNormal"><font size="2" face="Calibri"><span style="font-size:11.0pt"><span>
</span>I’m writing a custom script to monitor a group of run away java scripts memory hog.
<u></u><u></u></span></font></p>
<p class="MsoNormal"><font size="2" face="Calibri"><span style="font-size:11.0pt"><u></u> <u></u></span></font></p>
<p class="MsoNormal"><font size="2" face="Calibri"><span style="font-size:11.0pt"><span>
</span>Anyway, I’m trying to create a graph, which I’m never good at.<u></u><u></u></span></font></p>
<p class="MsoNormal"><font size="2" face="Calibri"><span style="font-size:11.0pt"><u></u> <u></u></span></font></p>
<p class="MsoNormal"><font size="2" face="Calibri"><span style="font-size:11.0pt"><span>
</span>Anyway, the rrd file was created immediately, when I first put in the entry to TEST2RRD and a NCV_Testname line in xymonserver.cfg.<u></u><u></u></span></font></p>
<p class="MsoNormal"><font size="2" face="Calibri"><span style="font-size:11.0pt"><u></u> <u></u></span></font></p>
<p class="MsoNormal"><font size="2" face="Calibri"><span style="font-size:11.0pt"><span>
</span>A couple of iterations of the data, <span> </span>changing names etc. I deleted the rrd file (which was updating some data), killed the rrd processes to the xymon server. It didn’t recreate the file. So I restarted xymon completely
on the server. <u></u><u></u></span></font></p>
<p class="MsoNormal"><font size="2" face="Calibri"><span style="font-size:11.0pt"><u></u> <u></u></span></font></p>
<p class="MsoNormal"><font size="2" face="Calibri"><span style="font-size:11.0pt"><span>
</span>All I could think of is a process holding on to that old file. <u></u><u></u></span></font></p>
<p class="MsoNormal"><font size="2" face="Calibri"><span style="font-size:11.0pt"><u></u> <u></u></span></font></p>
<p class="MsoNormal"><font size="2" face="Calibri"><span style="font-size:11.0pt"><span>
</span>So does anyone know the magic to get an RRD file to recreate on the server?<u></u><u></u></span></font></p>
<p class="MsoNormal"><font size="2" face="Calibri"><span style="font-size:11.0pt"><u></u> <u></u></span></font></p>
<p class="MsoNormal"><font size="2" face="Calibri"><span style="font-size:11.0pt"><span>
</span>BTW, a second server that also has the test, does have the rrd file, and it updates the current data, but no historical data.<u></u><u></u></span></font></p>
