Suricata Input Plugin

This plugin reports internal performance counters of the Suricata IDS/IPS engine, such as captured traffic volume, memory usage, uptime, flow counters, and much more. It provides a socket for the Suricata log output to write JSON stats output to, and processes the incoming data to fit Telegraf's format.

Configuration

[[input.suricata]]
  ## Data sink for Suricata stats log.
  # This is expected to be a filename of a
  # unix socket to be created for listening.
  source = "/var/run/suricata-stats.sock"

  # Delimiter for flattening field keys, e.g. subitem "alert" of "detect"
  # becomes "detect_alert" when delimiter is "_".
  delimiter = "_"

Metrics

Fields in the 'suricata' measurement follow the JSON format used by Suricata's stats output. See http://suricata.readthedocs.io/en/latest/performance/statistics.html for more information.

All fields are numeric.

Suricata configuration

Suricata needs to deliver the 'stats' event type to a given unix socket for this plugin to pick up. This can be done, for example, by creating an additional output in the Suricata configuration file:

- eve-log:
    enabled: yes
    filetype: unix_stream
    filename: /tmp/suricata-stats.sock
    types:
      - stats:
         threads: yes
