etc in sync.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">The second server, actually kept the first serves hobbit-alerts.cfg file in a holding tank. No it’s alerts file had one alert, and that was for the first one.
If the first went down, it would run a script that would copy the alerts file in place, thus making it the primary. In that alerts file, there is a rule that looks for recovery of the first server, and when that happens, a script is run that copies the backup
alert file back in place. <o:p></o:p></span></p>

<p class="MsoNormal"><span lang="DA" style="font-size:10.0pt;font-family:"Arial","sans-serif"">Hi,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="DA" style="font-size:10.0pt;font-family:"Arial","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB" style="font-size:10.0pt;font-family:"Arial","sans-serif"">Im curious how you guys have achieved to setup Xymon for HA/redundancy – so that you can do maintenance etc. on 1 Xymon server, and still keep monitoring hosts
with the other.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB" style="font-size:10.0pt;font-family:"Arial","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB" style="font-size:10.0pt;font-family:"Arial","sans-serif"">I’ve looked at the different approaches in the “Administration Guide”, but they all have pros and cons and some are rather complex.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB" style="font-size:10.0pt;font-family:"Arial","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB" style="font-size:10.0pt;font-family:"Arial","sans-serif"">The goals I have: Being able to keep monitoring with 1 xymon server down – have all data etc. sync’ed between the 2 xymon servers, so I don’t miss out on historic
data – don’t get double notifications/alerts – easy administration.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB" style="font-size:10.0pt;font-family:"Arial","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB" style="font-size:10.0pt;font-family:"Arial","sans-serif"">We currently have 4 data centres, spread around on different locations – one possibility would be to have 1 xymon server in each data centre, with the local hosts
reporting in to that server, but how do I keep on monitoring those hosts, if the local xymon server crashes?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB" style="font-size:10.0pt;font-family:"Arial","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB" style="font-size:10.0pt;font-family:"Arial","sans-serif"">Hope you can answer some of my questions.<o:p></o:p></span></p>
