Tom,

oh yes, that’s a good point to start with.

Unfortunately i did run the trimhistory command several times since the server’s setup, but your idea brings me a step forward.

Sometimes it’s the simple things you don’t think about.

Thank you!

Christian

Christian,

    Perhaps the closest you might get would be to look for the oldest history log for each device on your Xymon server.  Something like this:

[xymon@xymon1 ~]$ ls -t data/histlogs/HP-OfficejetPro7740/conn/ | tail -1

Tue_May_18_15:24:24_2021

So I first started monitoring the conn test of my HP-OfficejetPro7740 printer on May 18, 2021.

Hi to the list,

i’m working with xymon since 2008 and i thought i can help myself out whereever it’s necessary.

Now we are in the situation that we need kind of a query to show the first occurance of a system configured in xymon (currently 956 monitored devices and services).

Looking through the man-pages i didn’t find any helpful hint, neither using command-line nor using any xymon report tool.

Due to the fact that we have different types of configured systems (linux servers configured as xymon client, linux servers that are pulled using xymon rclient, windows systems running either BBWin or PowerShell client) it’s hard to find a way to get such a list.

Looking through every single monitored system, then looking in any graph history to see if this is beginning within the last 576 days, this is not an option for us.

Further i’m aware of the fact, that -for many systems- this begins with the xymon server’s rollout.

Does anyone of you have an idea or a hint?

Regards from Germany

Christian
