The following table explains session information fields:
Table 14-5 Session Information Options
Field | Description |
---|---|
sessionID |
Session' ID generated by PGX server. |
source |
Descriptive string identifying the client session. |
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:
Theis_transient
field indicates if the graph is transient. A graph is transient if it is not loaded from an external source.
