No data after a few minutes with rsyslog 8.2108.0 or more recents versions

Hi,

Seems with 8.2108.0 they did some change on impstats module and this exporter isn't working properly anymore.

If i open the endpoint on Prometheus i only see this:

Any idea on how to fix it?

Hi! Thank you for your report.. I'll try to check it this weekend!

[mvrk69]

I have my impstats interval at 10s, if i change it to 60s seems to work a bit better, but still from time to time looses data for almost 2h.

I have another server running rsyslog 8.2106 without any problem, so seems the problem started with 8.2108

Attaching my config.
impstats.conf.txt

And the prometheus graphics when i changed the interval to 60s.
