procfs
This package provides functions to retrieve system, kernel, and process metrics from the pseudo-filesystems /proc and /sys.
WARNING: This package is a work in progress. Its API may still break in backwards-incompatible ways without warnings. Use it at your own risk.
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.
fs, err := procfs.NewFS("/proc")
stats, err := fs.Stat()
Some sub-packages such as blockdevice, require access to both the proc and sys filesystems.
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 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.
rm -rf 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 fixtures.ttar.
