I just recognized a surpricingly behaviour of the Windows agent. I opened a file inside C:\ProgramData\icinga2\var\lib\icinga2\api\zones
and for other reason I did a reload of icinga2 at the master. The result was a incomplete staging of zones (without any error indication).
For another test I just opened the Windows explorer and navigate to C:\ProgramData\icinga2\var\lib\icinga2\api\zones
and with that the staging fails completely (again without any error indication).
Therefore, I’d assume during reload of the agent the directory C:\ProgramData\icinga2\var\lib\icinga2\api\zones
is deleted and re-created?
