That is. I need to monitor 5000 servers with metricbeat and I need help to know how many nodes and hardware is recommended. Thank You! ---

Presumably, that would depend on how much log output these 5000 servers generate. 1 log line per minute isnt very much. 1 log line per second is noticable 5 log lines per second is "heavy" πŸ™‚ ---

It’s about 5 or more log lines per second 😱 ---

The only real answer here is to [benchmark](https://esrally.readthedocs.io/en/stable/) your workload yourself. It's [definitely possible to index over 100,000 log lines per second](https://elasticsearch-benchmarks.elastic.co/index.html#tracks/http-logs/nightly/default/30d) on a [fairly small](https://elasticsearch-benchmarks.elastic.co/index.html#) cluster, but the details very much depend on the workload and the hardware you have available. ---
