I don’t think the the host shown in your screenshot has the config with “No agent” and “No SNMP”.
You see it on the received error text. --> “[agent] Communication failed…”
Check the WATO config of this host and active any changes.
If you only set the folder properties then the host can have different explizit settings.
Please check your host inside WATO directly and if this not helps you can also do a “cmk -D hostname” to see the result on the command line.
Again - show the output of a “cmk -D hostname” from the command line of your monitoring instance.
Without the knowledge if the host is configured correctly or not, it is not possible to say anything.
Number 1 is not a system tag. It looks like the old agent tag from before 1.6
but “tcp:tcp” is set and also the “cmk-agent” tag is there. It is not important that it belongs to a different tag group. In the end this means agent is active on this host.
Yes but it is showing in Host problems in the screen please refer to the screenshot
When I open the host problems screen the server with 06 is showing as down.
That’s are an other question as before. Configure not the “Smart Ping” as host check but the classic ping like your active ping check shown in the screenshot. Without so see more information this is the only advice i can give.
If booth use the same IP it must work.
Rule “host check command”
