[[configuration-general-options]] == Specify general settings You can specify settings in the +{beatname_lc}.yml+ config file to control the general behavior of {beatname_uc}. This includes: * <> that control things like the maximum random delay to apply to the startup of a metricset. * <> that are supported by all Elastic Beats. [float] [[configuration-global-options]] === Global Metricbeat configuration options These options are in the `metricbeat` namespace. [float] ==== `metricbeat.max_start_delay` The maximum random delay to apply to the startup of a metricset. Random delays ranging from [0, _max_start_delay_) are applied to reduce the thundering herd effect that can occur if a fleet of machines running Metricbeat are restarted at the same time. Specifying a value of 0 disables the startup delay. The default is 10s. [source,yaml] ---- metricbeat.max_start_delay: 10s ---- include::../../libbeat/docs/generalconfig.asciidoc[]
