Hi, I'm building a monitoring system for HBase and want to set up default alerts (threshold or anomaly) on 2-3 key metrics everyone who uses HBase typically wants to alert on, but I don't yet have production-grade experience with HBase.
Importantly, alert rules have to be generally useful, so can't be on metrics whose values vary wildly based on the size of deployment. In other words, which metrics would be most significant indicators that something went wrong with your HBase? I thought the best place to find experienced HBase users, who would find answering this question trivial, would be here. Thanks very much, Mark
