　　The event types are a controlled set, defined by Supervisor itself. 　　There is no way to add an event type without changing 　　itself. This is typically not a problem, 　　though, because metadata is attached to events that can be used by 　　event listeners as additional filter criterion, in conjunction with 　　its type. 　　Event types that may be subscribed to by event listeners are 　　predefined by supervisor and fall into several major categories, 　　including “process state change”, “process communication”, and 　　“supervisor state change” events. Below are tables describing 　　these event types. 　　In the below list, we indicate that some event types have a “body” 　　which is a a token set. A token set consists of a set of characters 　　with space-separated tokens. Each token represents a key-value pair. 　　The key and value are separated by a colon. For example: 　　processname:cat groupname:cat from_state:STOPPED 　　Token sets do not have a linefeed or carriage return character at 　　their end. 　　The base event type. This event type is abstract. It will never be 　　sent directly. Subscribing to this event type will cause a subscriber 　　to receive all event notifications emitted by Supervisor. 　　Name: 　　Subtype Of: N/A 　　Body Description: N/A 　　This process type indicates a process has moved from one state to 　　another. See for a description of the states 　　that a process moves through during its lifetime. This event type is 　　abstract, it will never be sent directly. Subscribing to this event 　　type will cause a subscriber to receive event notifications of all the 　　event types that are subtypes of . 　　Name: 　　Subtype Of: 　　Body Description 　　All subtypes of have a body which is a token set. 　　Additionally, each subtype’s token set has a default 　　set of key/value pairs: , , and 　　. represents the process name which 　　supervisor knows this process as. represents the name of 　　the supervisord group which this process is in. is the 　　name of the state from which this process is transitioning (the new 　　state is implied by the concrete event type). Concrete subtypes may 　　include additional key/value pairs in the token set. 　　Indicates a process has moved from a state to the STARTING state. 　　Name: 　　Subtype Of: 　　Body Description 　　This body is a token set. It has the default set of key/value pairs 　　plus an additional key. represents the number of 　　times this process has entered this state before transitioning to 　　RUNNING or FATAL (it will never be larger than the “startretries” 　　parameter of the process). For example: 　　processname:cat groupname:cat from_state:STOPPED tries:0 　　Indicates a process has moved from the state to the 　　state. This means that the process has successfully 　　started as far as Supervisor is concerned. 　　Name: 　　Subtype Of: 　　Body Description 　　This body is a token set. It has the default set of key/value pairs 　　plus an additional key. represents the UNIX 　　process id of the process that was started. For example: 　　processname:cat groupname:cat from_state:STARTING pid:2766 　　Indicates a process has moved from the state to the 　　state. This means that the process did not successfully 　　enter the RUNNING state, and Supervisor is going to try to restart it 　　unless it has exceeded its “startretries” configuration limit. 　　Name: 　　Subtype Of: 　　Body Description 　　This body is a token set. It has the default set of key/value pairs 　　plus an additional key. represents the number of 　　times this process has entered this state before transitioning to 　　or (it will never be larger than the 　　“startretries” parameter of the process). For example: 　　processname:cat groupname:cat from_state:STOPPED tries:0 　　Indicates a process has moved from either the state or the 　　state to the state. 　　Name: 　　Subtype Of: 　　Body Description 　　This body is a token set. It has the default set of key/value pairs 　　plus an additional key. represents the UNIX process 　　id of the process that was started. For example: 　　processname:cat groupname:cat from_state:STARTING pid:2766 　　Indicates a process has moved from the state to the 　　state. 　　Name: 　　Subtype Of: 　　Body Description 　　This body is a token set. It has the default set of key/value pairs 　　plus two additional keys: and . 　　represents the UNIX process id of the process that exited. 　　represents whether the process exited with an expected 　　exit code or not. It will be if the exit code was unexpected, 　　or if the exit code was expected. For example: 　　processname:cat groupname:cat from_state:RUNNING expected:0 pid:2766 　　Indicates a process has moved from the state to the 　　state. 　　Name: 　　Subtype Of: 　　Body Description 　　This body is a token set. It has the default set of key/value pairs 　　plus an additional key. represents the UNIX process 　　id of the process that was started. For example: 　　processname:cat groupname:cat from_state:STOPPING pid:2766 　　Indicates a process has moved from the state to the 　　state. This means that Supervisor tried 　　number of times unsuccessfully to start the process, and gave up 　　attempting to restart it. 　　Name: 　　Subtype Of: 　　Body Description 　　This event type is a token set with the default key/value pairs. For 　　example: 　　processname:cat groupname:cat from_state:BACKOFF 　　Indicates a process has moved from any state to the state 　　(indicates an error in ). This state transition 　　will only happen if itself has a programming 　　error. 　　Name: 　　Subtype Of: 　　Body Description 　　This event type is a token set with the default key/value pairs. For 　　example: 　　processname:cat groupname:cat from_state:BACKOFF 　　An event type raised when the 　　method is called on Supervisor’s RPC interface. The and 　　are arguments of the RPC method. 　　Name: 　　Subtype Of: 　　Body Description 　　type:type 　　data 　　An event type emitted when a process writes to stdout or stderr. The 　　event will only be emitted if the file descriptor is not in capture 　　mode and if or 　　config options are set to . This event type is abstract, it 　　will never be sent directly. Subscribing to this event type will 　　cause a subscriber to receive event notifications for all subtypes of 　　. 　　Name: 　　Subtype Of: 　　Body Description: N/A 　　Indicates a process has written to its stdout file descriptor. The 　　event will only be emitted if the file descriptor is not in capture 　　mode and if the config option is set to 　　. 　　Name: 　　Subtype Of: 　　Body Description 　　processname:name groupname:name pid:pid channel:stdout 　　data 　　Indicates a process has written to its stderr file descriptor. The 　　event will only be emitted if the file descriptor is not in capture 　　mode and if the config option is set to 　　. 　　Name: 　　Subtype Of: 　　Body Description 　　processname:name groupname:name pid:pid channel:stderr 　　data 　　An event type raised when any process attempts to send information 　　between and 　　tags in its output. This event type is abstract, it will never be 　　sent directly. Subscribing to this event type will cause a subscriber 　　to receive event notifications for all subtypes of 　　. 　　Name: 　　Subtype Of: 　　Body Description: N/A 　　Indicates a process has sent a message to Supervisor on its stdout 　　file descriptor. 　　Name: 　　Subtype Of: 　　Body Description 　　processname:name groupname:name pid:pid 　　data 　　Indicates a process has sent a message to Supervisor on its stderr 　　file descriptor. 　　Name: 　　Subtype Of: 　　Body Description 　　processname:name groupname:name pid:pid 　　data 　　An event type raised when the state of the 　　process changes. This type is abstract, it will never be sent 　　directly. Subscribing to this event type will cause a subscriber to 　　receive event notifications of all the subtypes of 　　. 　　Name: 　　Subtype Of: 　　Body Description: N/A 　　Indicates that has started. 　　Name: 　　Subtype Of: 　　Body Description: Empty string 　　Indicates that is stopping. 　　Name: 　　Subtype Of: 　　Body Description: Empty string 　　An event type that may be subscribed to for event listeners to receive 　　“wake-up” notifications every N seconds.
