// NewGoCollector returns a collector that exports metrics about the current Go
|
||||
// process. This includes memory stats. To collect those, runtime.ReadMemStats
|
||||
// is called. This requires to “stop the world”, which usually only happens for
|
||||
// garbage collection (GC). Take the following implications into account when
|
||||
// deciding whether to use the Go collector:
|
||||
//
|
||||
// 1. The performance impact of stopping the world is the more relevant the more
|
||||
// frequently metrics are collected. However, with Go1.9 or later the
|
||||
// stop-the-world time per metrics collection is very short (~25µs) so that the
|
||||
// performance impact will only matter in rare cases. However, with older Go
|
||||
// versions, the stop-the-world duration depends on the heap size and can be
|
||||
// quite significant (~1.7 ms/GiB as per
|
||||
// https://go-review.googlesource.com/c/go/+/34937).
|
||||
//
|
||||
// 2. During an ongoing GC, nothing else can stop the world. Therefore, if the
|
||||
// metrics collection happens to coincide with GC, it will only complete after
|
||||
// GC has finished. Usually, GC is fast enough to not cause problems. However,
|
||||
// with a very large heap, GC might take multiple seconds, which is enough to
|
||||
// cause scrape timeouts in common setups. To avoid this problem, the Go
|
||||
// collector will use the memstats from a previous collection if
|
||||
// runtime.ReadMemStats takes more than 1s. However, if there are no previously
|
||||
// collected memstats, or their collection is more than 5m ago, the collection
|
||||
// will block until runtime.ReadMemStats succeeds. (The problem might be solved
|
||||
// in Go1.13, see https://github.com/golang/go/issues/19812 for the related Go

# procfs
|
||||
|
||||
This procfs package provides functions to retrieve system, kernel and process
|
||||
metrics from the pseudo-filesystem proc.
|
||||
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.

[](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, current 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()
|
||||
```
|
||||
|
||||
## Building and Testing
|
||||
|
||||
The procfs library is normally built as part of another application. However, when making
|
||||
changes to the library, the `make test` command can be used to run the API test suite.
|
||||
|
||||
### 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 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`.
