Its API may still break in +backwards-incompatible ways without warnings. Use it at your own risk. + +[![Go Reference](https://pkg.go.dev/badge/github.com/prometheus/procfs.svg)](https://pkg.go.dev/github.com/prometheus/procfs) +[![CircleCI](https://circleci.com/gh/prometheus/procfs/tree/master.svg?style=svg)](https://circleci.com/gh/prometheus/procfs/tree/master) +[![Go Report Card](https://goreportcard.com/badge/github.com/prometheus/procfs)](https://goreportcard.com/report/github.com/prometheus/procfs) + +## Usage + +The procfs library is organized by packages based on whether the gathered data is coming from +/proc, /sys, or both. Each package contains an `FS` type which represents the path to either /proc, +/sys, or both. For example, cpu statistics are gathered from +`/proc/stat` and are available via the root procfs package. First, the proc filesystem mount +point is initialized, and then the stat information is read. + +```go +fs, err := procfs.NewFS("/proc") +stats, err := fs.Stat() +``` + +Some sub-packages such as `blockdevice`, require access to both the proc and sys filesystems. + +```go + fs, err := blockdevice.NewFS("/proc", "/sys") + stats, err := fs.ProcDiskstats() +``` + +## Package Organization + +The packages in this project are organized according to (1) whether the data comes from the `/proc` or +`/sys` filesystem and (2) the type of information being retrieved. For example, most process information +can be gathered from the functions in the root `procfs` package. Information about block devices such as disk drives +is available in the `blockdevices` sub-package. + +## Building and Testing + +The procfs library is intended to be built as part of another application, so there are no distributable binaries. +However, most of the API includes unit tests which can be run with `make test`. + +### Updating Test Fixtures + +The procfs library includes a set of test fixtures which include many example files from +the `/proc` and `/sys` filesystems. These fixtures are included as a [ttar](https://github.com/ideaship/ttar) file +which is extracted automatically during testing. To add/update the test fixtures, first +ensure the `fixtures` directory is up to date by removing the existing directory and then +extracting the ttar file using `make fixtures/.unpacked` or just `make test`. + +```bash +rm -rf testdata/fixtures +make test +``` + +Next, make the required changes to the extracted files in the `fixtures` directory. When +the changes are complete, run `make update_fixtures` to create a new `fixtures.ttar` file +based on the updated `fixtures` directory. And finally, verify the changes using +`git diff testdata/fixtures.ttar`. -- cgit v1.2.3
