We really like influx and heavily use the dimensioning feature in the TSD. Are there any influx like alternatives that are cheaper? I am willing to allocate $3,000 - $5,000 dollars (per annum) for this.
If you are positive that you need a cluster, here are my suggestions: * Recently Elasticsearch has become a lot better at time series data, so it might be worth a try. * My second bet would be Cassandra. Look at these slides for more info: http://de.slideshare.net/patrickmcfadin/time-series-with-apa... Not sure if this is supported by Grafana, though. * Another one would be Prometheus which also works with Grafana. Personally I'm not a big fan of its query language. Also clustering support is pretty limited there (and mostly needs to be handled by the client).
Will look more into Cassandra. Since it scales really well, it could well be worth investing time and money.
