Prometheus.io Process Collector [](https://hex.pm/packages/prometheus_process_collector) [](https://travis-ci.org/deadtrickster/prometheus_process_collector.erl)
=====
Collector which exports the current state of process metrics including cpu, memory, file descriptor usage and native threads count as well as the process start and up times.
Uses /proc, **Linux-only**.
Example scrape:
```
# TYPE process_open_fds gauge
# HELP process_open_fds Number of open file descriptors.
process_open_fds 11
# TYPE process_max_fds gauge
# HELP process_max_fds Maximum number of open file descriptors.
process_max_fds 20000
# TYPE process_start_time_seconds gauge
# HELP process_start_time_seconds Start time of the process since unix epoch in seconds.
process_start_time_seconds 1469491524
# TYPE process_uptime_seconds gauge
# HELP process_uptime_seconds Process uptime in seconds.
process_uptime_seconds 18
# TYPE process_threads_total gauge
# HELP process_threads_total Process Threads count.
process_threads_total 18
# TYPE process_virtual_memory_bytes gauge
# HELP process_virtual_memory_bytes Virtual memory size in bytes.
process_virtual_memory_bytes 2785275904
# TYPE process_resident_memory_bytes gauge
# HELP process_resident_memory_bytes Resident memory size in bytes.
process_resident_memory_bytes 57053184
# TYPE process_cpu_seconds_total counter
# HELP process_cpu_seconds_total Process CPU seconds total.
process_cpu_seconds_total{kind="utime"} 2.46
process_cpu_seconds_total{kind="stime"} 5.44
```
Usage
-----
You can register this collector manually using `prometheus_process_collector/0,1` or use `default_collectors` env entry for `prometheus`.
With [Prometheus Plugs](https://github.com/deadtrickster/prometheus-plugs) - just add prometheus_process_collector dependency to top-level project (i.e. [like here](https://github.com/deadtrickster/prometheus-plugs-example/edit/master/mix.exs)).
