Hi, we're using Nagflux 0.4.1, InfluxDB 1.8, and Naemon following steps here https://support.nagios.com/kb/article/nagios-core-performance-graphs-using-influxdb-nagflux-grafana-histou-802.html#Nagflux_Config.

When starting Nagflux, the db can be created in influxDB. However, no data is sent to influxDB.

We found that Nagflux keeps starting (always sees Started Nagflux) and read on the same performance data file /var/spool/nagflux/1663209466.perfdata.host which is the first one in the spool directory:

Since it's a testing Naemon, there is only 1 host with few monitors. Most of the performance data file are empty:
