We are evaluating elasticsearch for logging and there are many use cases where it's a perfect match. The question is should we also consider something like graphite for simple metrics (number of logins, visitors, response time, etc.)
It seems that graphite stores the data more compactly and I've seen people say the graphing is better in graphite. But it seems there might be an advantage in having all the metrics in one tool.
I'm curious what people here think and do? Do you also install graphite for these kinds of metrics or do everything with ELK?
