passenger-status - inspect Phusion Passenger’s internal status
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
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.
pid The process ID of the Phusion Passenger instance you want to
