Caution

Grafana Alloy is the new name for our distribution of the OTel collector. Grafana Agent has been deprecated and is in Long-Term Support (LTS) through October 31, 2025. Grafana Agent will reach an End-of-Life (EOL) on November 1, 2025. Read more about why we recommend migrating to Grafana Alloy.

squid_config

The squid_config block configures the squid integration, which is an embedded version of a forked version of the Squid_exporter. This integration allows you to collect third-party Squid metrics.

Full reference of options:

yaml 
  # Enables the Squid integration, allowing the Agent to automatically
  # collect metrics for the specified Squid instance.
  [enabled: <boolean> | default = false]

  # Sets an explicit value for the instance label when the integration is
  # self-scraped. Overrides inferred values.
  #
  # The default value for this integration is the configured host:port of the connection string.
  [instance: <string>]

  # Automatically collect metrics from this integration. If disabled,
  # the Squid integration is run but not scraped and thus not
  # remote-written. Metrics for the integration are exposed at
  # /integrations/squid/metrics and can be scraped by an external
  # process.
  [scrape_integration: <boolean> | default = <integrations_config.scrape_integrations>]

  # How often should the metrics be collected? Defaults to
  # prometheus.global.scrape_interval.
  [scrape_interval: <duration> | default = <global_config.scrape_interval>]

  # The timeout before considering the scrape a failure. Defaults to
  # prometheus.global.scrape_timeout.
  [scrape_timeout: <duration> | default = <global_config.scrape_timeout>]

  # Allows for relabeling labels on the target.
  relabel_configs:
    [- <relabel_config> ... ]

  # Relabel metrics coming from the integration, lets you drop series
  # that you don't care about from the integration.
  metric_relabel_configs:
    [ - <relabel_config> ... ]

  # How frequently the WAL is truncated for this integration.
  [wal_truncate_frequency: <duration> | default = "60m"]

  #
  # Exporter-specific configuration options
  #

  # The address used to connect to the Squid instance in the format
  # of <HOST>:<PORT>.
  # i.e. "localhost:3128"
  [address: <string>]

  # The username for squid instance.
  [username: <string>]

  # The password for username above.
  [password: <string>]
