<div>Sorry, I should have been a bit more precise in this regard:</div>
<div>- test disabled are disabled via enable/disable from the Administration menu for some period of time, e.g. 2 hours, without "until OK" checked. It doesn't matter if you're blueing out a green (e.g. planned downtime) or red test. The problem remains the same.</div>
<div>- the restart is done to make changes visible immediately for checking the change after applying it</div>
<div>- dropped tests are of checks (or hosts) which don't exist anymore, so there won't be any checks coming in for the checks/hosts dropped</div>
<div> </div>
<div>Yes when waiting for some time before restarting after disabling or dropping a check, that change will "survive" the restart. As pointed out in Jeremy Laidman's post, this indeed seems to be due to the checkpoint interval which is 600 seconds in the local configuration.</div>
<div> </div>
<div><br/>
Kind regards,</div>
<div>Sven</div>

Are you checking the “until OK” or are you providing a time limit for the disable? Also, if the test is green why would you want it disabled?</span></font></p>
<p class="MsoNormal"><font color="#1f497d" face="Calibri" size="2"><span style="font-size: 11.0pt;font-family: Calibri , sans-serif;color: rgb(31,73,125);"> </span></font></p>

All configuration files are re-read (except local-client.cfg) every 5 minutes.</span></font></p>
<p class="MsoNormal"><font color="#1f497d" face="Calibri" size="2"><span style="font-size: 11.0pt;font-family: Calibri , sans-serif;color: rgb(31,73,125);"> </span></font></p>

Well of course. If the client is providing the test to the server, the server is going to display it. If you don’t want a test in xymon, it has to be disabled at the source.</span></font></p>

<p class="MsoNormal"><font face="Verdana" size="1"><span style="font-size: 9.0pt;font-family: Verdana , sans-serif;">Hello everybody,</span></font></p>
</div>
<div>
<p class="MsoNormal"><font face="Verdana" size="1"><span style="font-size: 9.0pt;font-family: Verdana , sans-serif;"> </span></font></p>

<div>
<p class="MsoNormal"><font face="Verdana" size="1"><span style="font-size: 9.0pt;font-family: Verdana , sans-serif;">recently I've been seeing a strange issue on xymon server. When I make a check blue and shortly after xymon gets restarted due to configuration updates, that blue check will be green again afterwards. The same thing happens when a check is dropped and xymon gets restarted directly after that: the dropped check reappears.</span></font></p>
</div>
<div>
<p class="MsoNormal"><font face="Verdana" size="1"><span style="font-size: 9.0pt;font-family: Verdana , sans-serif;">If you wait some amount of time before restarting, say 5-10 minutes, the problem won't appear and everything will be fine. I also sync'ed on the server directly after making a check blue and before restarting (to avoid data not being written to disk for some strange reason), which unfortunately did not help.</span></font></p>
</div>
<div>
<p class="MsoNormal"><font face="Verdana" size="1"><span style="font-size: 9.0pt;font-family: Verdana , sans-serif;">Environment is xymon 4.3.27 on Debian jessie. Xymon has been updated to 4.3.28 because of this problem lately, with the problem appearing in 4.3.28, too. This server has just been upgraded from Debian wheezy to Jessie a few weeks ago. On wheezy xymon 4.3.27 was in use but didn't show this behaviour.</span></font></p>

</div>
<div>
<p class="MsoNormal"><font face="Verdana" size="1"><span style="font-size: 9.0pt;font-family: Verdana , sans-serif;">Did anybody notice such an odd behaviour or maybe have any thoughts regarding possible causes?</span></font></p>
