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?

i am also interested in this. Do we have another alternative to influxdb ? Clickhouse/timescale/quest ..

Currently there are 4 Variants:
Graphite
InfluxDB
InfluxDB2
OpenTSDB

Graphite is pretty much in life support rn, but its working and i am very sure it will continue doing so.
InfluxDB and InfluxDB2… Well, InfluxDB3 is not a good option for most Icinga Users (Retention are 3 Days in their OSS Edition), and we just dont know when they will deprecate InfluxDB2)
About OpenTSDB, i tried it for once, but i literally never saw a setup running it.

As far as i know currently other backends are in evaluation by some Icinga Partners.

since victoria metrics is working with the icinga2 influxdb1writer this can also be used
