memcached_exporter_config

The memcached_exporter_config block configures the memcached_exporter integration, which is an embedded version of memcached_exporter. This allows for the collection of metrics from memcached servers.

Note that currently, an Agent can only collect metrics from a single memcached server. If you want to collect metrics from multiple servers, you can run multiple Agents and add labels using relabel_configs to differentiate between the servers:

yaml
memcached_exporter:
  enabled: true
  memcached_address: memcached-a:53
  relabel_configs:
  - source_labels: [__address__]
    target_label: instance
    replacement: memcached-a

Full reference of options:

yaml
  # Enables the memcached_exporter integration, allowing the Agent to automatically
  # collect system metrics from the configured memcached server address
  [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 inferred from
  # memcached_address.
  [instance: <string>]

  # Automatically collect metrics from this integration. If disabled,
  # the memcached_exporter integration will be run but not scraped and thus not
  # remote-written. Metrics for the integration will be exposed at
  # /integrations/memcached_exporter/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, allowing to drop series
  # from the integration that you don't care about.
  metric_relabel_configs:
    [ - <relabel_config> ... ]

  # How frequent to truncate the WAL for this integration.
  [wal_truncate_frequency: <duration> | default = "60m"]

  # Monitor the exporter itself and include those metrics in the results.
  [include_exporter_metrics: <bool> | default = false]

  #
  # Exporter-specific configuration options
  #

  # Address of the memcached server in host:port form.
  [memcached_address: <string> | default = "localhost:53"]

  # Timeout for connecting to memcached.
  [timeout: <duration> | default = "1s"]
