Procstat Input Plugin

The procstat plugin can be used to monitor the system resource usage of one or more processes. The procstat_lookup metric displays the query information, specifically the number of PIDs returned on a search

Processes can be selected for monitoring using one of several methods:

  • pidfile
  • exe
  • pattern
  • user
  • systemd_unit
  • cgroup
  • win_service
# Monitor process cpu and memory usage
  ## PID file to monitor process
  pid_file = "/var/run/"
  ## executable name (ie, pgrep <exe>)
  # exe = "nginx"
  ## pattern as argument for pgrep (ie, pgrep -f <pattern>)
  # pattern = "nginx"
  ## user as argument for pgrep (ie, pgrep -u <user>)
  # user = "nginx"
  ## Systemd unit name, supports globs when include_systemd_children is set to true
  # systemd_unit = "nginx.service"
  # include_systemd_children = false
  ## CGroup name or path
  # cgroup = "systemd/system.slice/nginx.service"

  ## Windows service name
  # win_service = ""

  ## override for process_name
  ## This is optional; default is sourced from /proc/<pid>/status
  # process_name = "bar"

  ## Field name prefix
  # prefix = ""

  ## When true add the full cmdline as a tag.
  # cmdline_tag = false

  ## Mode to use when calculating CPU usage. Can be one of 'solaris' or 'irix'.
  # mode = "irix"

  ## Add the PID as a tag instead of as a field.  When collecting multiple
  ## processes with otherwise matching tags this setting should be enabled to
  ## ensure each process has a unique identity.
  ## Enabling this option may result in a large number of series, especially
  ## when processes have a short lifetime.
  # pid_tag = false

  ## Method to use when finding process IDs.  Can be one of 'pgrep', or
  ## 'native'.  The pgrep finder calls the pgrep executable in the PATH while
  ## the native finder performs the search directly in a manor dependent on the
  ## platform.  Default is 'pgrep'
  # pid_finder = "pgrep"
Windows support

Preliminary support for Windows has been added, however you may prefer using the win_perf_counters input plugin as a more mature alternative.
