If you’re looking into time-series based monitoring&#x2F;alerting, I’ve been delighted with <a href="http:&#x2F;&#x2F;prometheus.io&#x2F;" rel="nofollow">http:&#x2F;&#x2F;prometheus.io&#x2F;</a>.<p>I’m mentioning this because I previously tried to use OpenTSDB for monitoring (back when prometheus and others didn’t exist), and found it too cumbersome to run (not packaged in Debian, requires an underlying HBase instance, etc.) for my taste. Many more recently created projects, such as Prometheus, come pre-packaged in a Docker container and can run on a single host — often they’re even a single binary.
