Hi,
Please enable debug_connection = true
in your s7comm config and provide the complete logs. I would like to see the full set of attempts made and the final shutdown, not just the first debug connection message.
In general, telegraf will fail to start up if it fails to connect to a device. This is the expected behavior as it makes it very clear that something is wrong to the user. It could be a bad password, connection, etc. We have added some connection error retry logic to some plugins and could possibly add this here, but I would like to see a complete set of logs first.
Thanks

you are welcome!
after setting debug_connection = true I got the logs below:

connection error retry logic to some plugins
I think connection error retry logic for this plugins is very useful given our plant network situation, Thanks

@GitTurboy just for my understanding, do you see an error message in the log or does it stop with D! [inputs.s7comm] Connecting to ...
? In my tests I always see an error that the connection failed...

if run as a service , the log were just same as what I posted. 【and the service will stoped !】
if run as console. app, the log contains:

@GitTurboy please test the binary in PR #15655, available as soon as CI finished the tests, and let me know if this fixes the issue! You should set startup_error_behavior = "retry"
for the plugin to make the plugin retrying to connect in every gather cycle without failing.
from telegraf.
startup_error_behavior = "retry"
I have tried and All looks well. After observer several days, I will close this problem. Thank you!
from telegraf.
@GitTurboy please don't close the issue, it will automatically be closed as soon as we do merge the corresponding PR! Anyway, please let me know in here how your tests went, even though the issue might be closed already! In case of any problem feel free to reopen the issue!
