Thanks, but it seems that i am to stupid…
Strange thing is that the config of the container is showing:
"org.opencontainers.image.description": "Check_MK is a leading tool for Infrastructure & Application Monitoring",
"org.opencontainers.image.vendor": "Mathias Kettner GmbH",
So Version 1.5.0p18. That could be the former version, but after login it definitvely shows p24. And there is no volume attached.
Maybe i am faster with creating the monitors from scratch, but would like to understand why the monitors are gone.
Tried a lot of unused volumes in a new container but also without any luck.
I am using docker on a synology and have installed portainer for a while. I know i have modified something in the network area of the conainer and needed to replace it. So maybe within this process a new image was pulled, but then i should be able to use the old one…
