Hi @andreas-doehler,
We have the notification inside this path:
/opt/omd/sites/checkmk/local/share/check_mk/notifications
but I could see no file inside notifications
[root@sekatecheckmk ~]# cd /opt/omd/sites/checkmk/local/share/check_mk/
[root@sekatecheckmk check_mk]# ls
agents alert_handlers checkman checks inventory locale mibs notifications pnp-rraconf pnp-templates reporting web
[root@sekatecheckmk check_mk]# cd notifications/
[root@sekatecheckmk notifications]# ls
[root@sekatecheckmk notifications]#
