Prometheus Infra Cost

[Shivali Chauhan]

Hi Team,

Could you please help me on Prometheus cost.

How much it will cost for 400 servers for system monitoring for 1 year data retention.

Regards,

Shivali Chauhan

There is no cost for the Prometheus software.

The hardware cost will depend on what you are using (AWS, Azure, VMware,
etc.) and the number of metrics you are storing.

1 year data retention for 400+ servers needs a bit of design before assessing tye cost. There is the metrics size, the number of prometheus instances, federated prometheis and of course your remote storage (assuming 1 year retention is the company policy thus you need to rethink storage security and replication etc )

It highly depends on how much data you ingest per server. Just monitoring basic node metrics is pretty cheap. But monitoring a dozen services per node can require more Prometheus instances.

At a minimum, you probably want to have two instances for HA.

Without a lot more detailed information on what exactly you want to monitor, it's hard to determine exactly.

It could be anywhere between 150:1 and 1000:1 monitoring to node ratio.

Thank you for the information. 

Could you please little bit explain me 150:1 and 1000:1 monitoring to node ratio.

That part
