OpenTelemetry Collector - ICMP Check Receiver

This receiver executes ICMP echo/ping requests to a list of targets and reports the results as metrics.

Features:

• List of created metrics:
  • ping_rtt: Round-trip time in milliseconds.
  • ping_rtt_min: Minimum round-trip time in milliseconds.
  • ping_rtt_max: Maximum round-trip time in milliseconds.
  • ping_rtt_avg: Average round-trip time in milliseconds.
  • ping_rtt_stddev: Standard deviation of round-trip time in milliseconds.
  • ping_loss_ratio: Packet loss ratio between 0 and 1.
• Name resolution errors will be logged as warnings and the target will be retried in the next scrape run.

Configuration

The receiver supports the following settings:

• collection_interval: The interval (duration, e.g. 1m) at which the scraper will run. See scrapehelper for all options.

• targets: A list of targets to ping.

  target:

  • target: The target to ping. This can be an IP address or hostname.
  • ping_count: The number of pings to send to the target.
  • ping_timeout: The timeout (duration, e.g. 5s) for this target. If ping_count pings are not received within this time, the execution will be stopped.

Example configuration:

receivers:
  icmpcheck:
    collection_interval: 10s
    targets:
      - target: www.amazon.de
        ping_count: 4
        ping_timeout: 5s
      - target: www.amazon.com
      - target: www.doesnot123exiiiiist.coom
      - target: api.amazon.com
      - target: api.amazon.de # request timeout
        ping_timeout: 2s
      - target: 8.8.8.8
