My understanding of Prometheus is that it doesn't support HA, fault-tolerant clustering either.

The recommendation from the Prometheus developers for HA and fault-tolerance/reliability is to run multiple Prometheus servers with one server scraping metrics from another server.

To do something similar in Monasca you could run multiple instances of InfluxDB using the Kafka metrics topic and multiple consumer groups to replicate all metrics to each InfluxDB server, or use the InfluxDB Relay project at, https://github.com/influxdata/influxdb-relay.

The non-clustered version of InfluxDB remains free and open-source. It is only the clustered version of InfluxDB that has now moved to a closed source license.

Hi, Monasca developers and users,

https://influxdata.com/blog/update-on-influxdb-clustering-high-availability-and-monetization/
"For our current and future customers, we’ll be offering clustering and high availability through Influx Cloud, our managed hosting offering, and Influx Enterprise, our on-premise offering, in the coming months.”


It seems like “clustering” and “high availablity” of influxDB will be available only in commercial version.
Monasca is currently leveraging influxDB as a metrics and alarm database. Beside vertical, influxDB is currently only an open source option to use.

With this update stating “influxDB open source sw version will not have clustering / ha feature”,
I would like to know if there has been any discussion among monasca community to add more database backend rather than influxDB, especially OpenTSDB.


Thank you.
