As a backend developer, I always need to monitor something — the state machine in the database, records count, message queue lag, custom application metrics, system performance, progress of my deployment scripts.
For a long time, I was trying to find a tool that could do keep everything in one place, alert me on a trigger, and be as fast and nimble as a local development tool. Heavy production monitoring systems can't help with such tasks; I needed a swiss army knife — something that could be configured in a minute and give me results right away.
