Can you confirm what version of docker and the docker python package you have installed? I can't replicate this.
Also what is the output of docker ps -a
Sure
The output of (echo fetch docker_status ; echo quit) | ./muninlite &>muninlite.log
:
# munin node at mypc
running.value 1
running.extinfo adoring_einstein (firefox:latest, 2024-02-17T23:35:33.797114657Z)
unhealthy.value 0
unhealthy.extinfo
paused.value 0
paused.extinfo
created.value 0
created.extinfo
restarting.value 0
restarting.extinfo
removing.value 0
removing.extinfo
exited.value 0
exited.extinfo
dead.value 0
dead.extinfo
.
The error, the above output produces is:
2024/02/18 01:20:09 [WARNING] 7 lines had errors while 9 lines were correct (43.75%) in data from 'fetch docker_status' on mypc/192.168.1.31:4949
Notes about above output:
