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.

This is documentation for the next version of Agent. For the latest stable release, go to the latest version.

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>]
