// 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

// collected memstats, or their collection is more than 5m ago, the collection

// deprecated and should be replaced by seconds. (3) The size of the request is
// calculated in a separate goroutine. Since this calculator requires access to
// the request header, it creates a race with any writes to the header performed
// during request handling. httputil.ReverseProxy is a prominent example for a
// handler performing such writes. (4) It has additional issues with HTTP/2, cf.

@ -9,3 +9,45 @@ backwards-incompatible ways without warnings. Use it at your own risk.
[![GoDoc](https://godoc.org/github.com/prometheus/procfs?status.png)](https://godoc.org/github.com/prometheus/procfs)
[![Build Status](https://travis-ci.org/prometheus/procfs.svg?branch=master)](https://travis-ci.org/prometheus/procfs)
[![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, 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`.

# 1.2.0
This new release introduces:
* A new method `SetReportCaller` in the `Logger` to enable the file, line and calling function from which the trace has been issued
* A new trace level named `Trace` whose level is below `Debug`
* A configurable exit function to be called upon a Fatal trace
* The `Level` object now implements `encoding.TextUnmarshaler` interface
# 1.1.1
This is a bug fix release.
* fix the build break on Solaris
* don't drop a whole trace in JSONFormatter when a field param is a function pointer which can not be serialized
# 1.1.0
This new release introduces:
* several fixes:
* a fix for a race condition on entry formatting
* proper cleanup of previously used entries before putting them back in the pool
* the extra new line at the end of message in text formatter has been removed
* a new global public API to check if a level is activated: IsLevelEnabled
* the following methods have been added to the Logger object
* IsLevelEnabled
* SetFormatter
* SetOutput
* ReplaceHooks
* introduction of go module
* an indent configuration for the json formatter
* output colour support for windows
* the field sort function is now configurable for text formatter
* the CLICOLOR and CLICOLOR\_FORCE environment variable support in text formater
# 1.0.6
This new release introduces:
* a new api WithTime which allows to easily force the time of the log entry
which is mostly useful for logger wrapper
* a fix reverting the immutability of the entry given as parameter to the hooks
a new configuration field of the json formatter in order to put all the fields
in a nested dictionnary
* a new SetOutput method in the Logger
* a new configuration of the textformatter to configure the name of the default keys
* a new configuration of the text formatter to disable the level truncation
# 1.0.5
* Fix hooks race (#707)
* Fix panic deadlock (#695)
# 1.0.4
* Fix race when adding hooks (#612)
* Fix terminal check in AppEngine (#635)

To ensure this behaviour even if a TTY is attached, set your formatter as follows:
```go
log.SetFormatter(&log.TextFormatter{
DisableColors: true,
FullTimestamp: true,
})
```
#### Logging Method Name
If you wish to add the calling method as a field, instruct the logger via:
```go
log.SetReportCaller(true)
```
This adds the caller as 'method' like so:
```json
{"animal":"penguin","level":"fatal","method":"github.com/sirupsen/arcticcreatures.migrate","msg":"a penguin swims by",
"time":"2014-03-10 19:57:38.562543129 -0400 EDT"}
```
```text
time="2015-03-26T01:27:38-04:00" level=fatal method=github.com/sirupsen/arcticcreatures.migrate msg="a penguin swims by" animal=penguin
```
Note that this does add measurable overhead - the cost will depend on the version of Go, but is
between 20 and 40% in recent tests with 1.6 and 1.7. You can validate this in your
environment via benchmarks:
```
go test -bench=.*CallerTracing
```
