Icinga2: What type of clustered timeseries database is supported?

Hello,

currently we are using Icinga2 in combination with a single InfluxDB instance.
Since we had some downtimes on that InfluxDB-node, we want to implement a time series DB HA cluster.

Timescale does support that, InfluxDB does not seem to have HA.
But as far as I am informed icinga2 does not support timescaleDB right know?

Confirmed. And adding it isn’t planned, yet.

What is the best open source practice when replication of a time series db is required?

Using influxdb with influxdb-relay?
