Ask HN: What are the differences between Influxdb+Grafana and ELK?

[vukers]

I've been looking into both stacks and it seems like they are both capable of visualizing and analyzing your collected metrics. Are there specific use-cases for each that differentiate the two?

Elasitcsearch is really a document database of sorts. Think of using it to store logs or messages.

InfluxDB is a time series database. Think of using it to store periodic measurement data (generally samples or point in time measurements).

For a complete solution you really need both of them.
