Checkmk Raw Edition 2.4.0p7
Ubuntu 24.04.2 LTS
I have followed the guide to add my AWS infrastructure to my Checkmk. This all works fine with no issues. I have also manually added hosts which works and I can see the monitoring data ok. After a while however (30 minutes, or 60 minutes, it seems random) Checkmk seems to lose access to the data, and I see this in my service problems:
I this is a vanilla install of Checkmk Raw 2.4, and is the first thing I have configured in the server. I have removed it all and re-added 3 times, but eventually it seems to lose the connection.
Any assistance would be appreciated! Thanks
