The following table explains session information fields:

Table 27-5 Session Information Options

Field	Description
sessionID	Session ID generated by the graph server (PGX)
source	Descriptive string identifying the client session
user	Session owner
task_timeout_ms	Timeout to interrupt long-running tasks submitted by sessions (algorithms, I/O tasks) in milliseconds. Set to zero for infinity/no timeout.
idle_timeout_ms	Timeout of idling sessions in milliseconds. Set to zero for infinity/no timeout.
alive_ms	Session's age in milliseconds
total_analysis_time_ms	Total session's executing time in milliseconds
state	Current session of the session can be Idle, Submitted, Released or Terminating
private_graphs	Session bounded graphs
published_graphs	Published graphs pointed to from the session

Note:

The is_transient field indicates if the graph is transient. A graph is transient if it is not loaded from an external source.
