MQTT telegraf InfluxDB only getting data-points every 10 seconds

Telegraf

Hello,

According to what I’ve read until now, the inputs.mqtt_consumer should be pushing messages through as it receives them (in my case the topic of interest is publishing about once per second).
However InfluxDB only shows a data-point every 10 seconds, and I would very much like to store all data-points this topic throws.
I’ve dropped every “interval” setting I could find to 1 second but and restarted more times than I care to count, yet this doesn’t seem to change anything.
Could someone point me in the right direction?

Edit: I’m beginning to think that this is an InfluxDB issue.
Because I’ve just implemented a workaround in nodeRed and, I’m still getting the same 10 second interval between data-points, while seeing nodeRed pushing data every second.

Nevermind…
It turns out InfluxDB defaults to 10 second window period in the data explorer.
Once I set this to custom 1s, my problems were gone.
