Add os release collector Currently Node Exporter has a metric called `node_uname_info` which of course exposes uname info. While this is nice, it does not help if you are running different OSes which could have similar uname info. Therefore parse `/etc/os-release` or `/usr/lib/os-release` and expose a `node_os_info` metric which provide information regarding the OS release/version of the node. Also expose the major.minor part of the OS release version as `node_os_version`. Since the os-release files will not change often, cache the parsed content and only refresh the cache if the modification time changes. This `os` collector will read files outside of `/proc` and `/sys`, but the os-release file is widely used and the format is standardized: https://www.freedesktop.org/software/systemd/man/os-release.html Bug: https://github.com/prometheus/node_exporter/issues/1574 Signed-off-by: Benjamin Drung <benjamin.drung@ionos.com> 2021-08-19 12:26:53 +02:00			`NAME="Ubuntu"`
