Hi,
I have a C9800-40 controller that does not send all configured telemetry data to our Telegraf/InfluxDB. Some subscriptions are sent, some not. This worked flawlessly for a few days, then some subscriptions stopped working without any change on our side. Some other subscriptions are continuing sending data.
I would like to restart the pubd process on the controller but don't know how to achieve this without reloading the whole box. Is there any command that I don't know about?
Thanks
Robin

I managed to solve the issue and it wasn't at all a problem with the C9800 controllers!
The problem was in out InfluxDB itself. From Telegraf, I got lots of the following errors:
E! [outputs.influxdb] E! [outputs.influxdb] Failed to write metric (will be dropped: 400 Bad Request): partial write: max-series-per-database limit exceeded: (1000000) dropped=348
So I enabled TSI on our InfluxDB and from then on, all data did it into the database.
Cheers

Hi,
CSCvy37351 seems to fit my issue. I will upgrade from 17.6.3 to 17.6.4 during the night an we will see what happens afterwards.
Thank you for the hint!

Upgrade did not help, the issue is persisting. I will do further investigations as soon as I have some time for it. I will keep the forum updated.
