Hi,
@r.sander My knowledge of python is quite poor so can I ask you for more information? from what i can see this script is official. there’s no documentation?
For more information I mean an example of using this script.
On the internet I find only a pdf of 2015.
link: https://checkmk.de/download/2015-Konferenz-Treasures.pdf
In which two examples are made:
Set a downtime
./downtime -v -d 10 -c “Check_MK Conference demo” -S DIWWGYFHXGUVLXJQAJKD
sdtcsynomd1
Remove a downtime
./downtime -r -v -d 10 -S DIWWGYFHXGUVLXJQAJKD sdtcsynomd1
but, I get the following error:
@ways I try to see your script. thank you 
thx you all.
Dario.
