passenger-status - inspect Phusion Passenger's internal status SYNOPSIS
passenger-status [pid] DESCRIPTION
passenger-status looks at the current status of a Phusion Passenger installation. It will locate Phusion Passenger automatically if it is running and will give you a list of instances if there is more than one Phusion Passenger instance running. You can then select the instance by specifying the relevant PID on the command line. The general information section shows the following details: max The maximum number of application instances that Phusion Passenger will spawn. This equals the value given for PassengerMaxPoolSize in the configuration. count The number of application instances that are currently alive. This value is always less than or equal to max. active The number of application instances that are currently processing requests. This value is always less than or equal to count. inactive The number of application instances that are currently not processing requests, i.e. are idle. Idle application instances will be shutdown after a while, as can be specified with PassengerPoolIdleTime in the configuration. The value of inactive equals count - active. The applications section shows each application instance, which directory it belongs to. The sessions field shows how many HTTP client are currently being processed by that application instance.
