While the PMM team works hard on our PMM 2.0 release, we have been working on a few things in the background which we’d like to show off ! In particular we have developed a new dashboard that displays metrics related to memory usage on Linux systems. The dashboard leverages information collected by node_exporter. The graphs take advantage of /proc filesystem files, specifically:
- meminfo: Provides information about distribution and utilization of memory. This varies by architecture and compile options.
- vmstat: Provides information about block IO and CPU activity in addition to memory.
