Practical articles from the team behind XorMon, LPAR2RRD and STOR2RRD: open source, IBM Power Systems, storage, cloud, alerting and the occasional strong opinion. Clear thinking on how to watch complex infrastructure, without the noise.
Practical notes on monitoring servers, storage, cloud and everything in between.
Open source is often treated as the budget option. In infrastructure monitoring, the more interesting argument is about control: who can read the code, who can fix it, and who decides what happens next.
A single busy afternoon tells you almost nothing. Capacity decisions live in the slope of the line over weeks and months, not in yesterday peak.
Shared processor pools and entitled capacity make Power a world of its own. Generic tools blur exactly the numbers that matter here.
A fresh cluster exposes thousands of metrics on day one. Most of them are noise until you decide what a healthy cluster is supposed to look like.
An alert that fires too often is worse than no alert at all. It teaches the on-call engineer, correctly, to ignore it.
The useful version of AI in monitoring is not a black box that declares verdicts. It is a faster way to ask the data honest questions.
