![]() ![]() I don't want another sar-metrics-as-line-graphs product that's somewhat better than the others. (This is often attributed to Henry Ford, although he probably never said it.) This reminded me of the quote: If I had asked people what they wanted, they would have said faster horses. ![]() I asked one monitoring vendor why they hadn't included latency heat maps, and their answer was that they build what customers ask for, and not enough customers had asked. Many of their products include some form of server or instance analysis capabilities, however, most are just sar metrics. Gartner has previously estimated these industries to be $1.8 billion and $1 billion respectively. The performance monitoring industry has dozens of companies focused on application performance monitoring, and on network performance monitoring and diagnostics. For vendors, this shows what's actually interesting and required. Last week I spoke at Monitorama in Portland on Netflix instance analysis requirements and desirables. There are many more operating system metrics, analysis capabilities, and visualizations that are possible, and should be included in Linux instance analysis tools. These are useful and do solve problems, but today they are the basics. If you haven't used the sar(1) tool, you are likely familiar with its metrics: load averages, CPU utilization, disk IOPS, disk average latency, etc. It's usually the same old sar metrics as line graphs. Most instance analysis and monitoring products of today are neither interesting nor are solving new problems.
