Can you suggest some sort of freeform monitoring tool?
I have been trying Graphite, which allows you to add any metrics you like, and graph them on the spot. You don't have to define a new host, service, whatever. If all you want is to graph something, you send data, and you can immediately graph it.
I'm looking for a more sophisticated of that. Features I'm looking for:
- Setting alert thresholds
- Adding more metadata to the metrics (app, host, unit, ...)
- Have a web front end to manipulate all those things
- Rules can be made to add metadata automatically depending on the name of the metric.
It seems most systems out there, other than Graphite, all expect a lot of up front work to add metrics, and I'm looking to avoid that. If I think a metric is worth keeping later, I'll categorize it later.
