with the coming ElasticSearch support in Grafana and ES 2.0, ES starts to look interesting as a metrics backend.
Is anyone using it already?
What kind of performance do you see? I plan on having around 500.000 - 1.000.000 metrics/s and another 2000 logs/s. Is that something that ES can take or is it too much? My cluster is quite small, 3 servers with 2x6cores(HT), 64gb of memory(can add more) and SAS hard drives.
How do you send data to ES? Over Logstash or directly?
Is some kind of metrics down sampling planned for ES?
