The Threads category provides status information about the threads that are in use by the server. Each thread is a separate execution path within a process. For example, the DB Event thread is an execution path within the ClearSCADA Database Server process. The threads allow the process to perform multiple tasks simultaneously.
The status of each thread is categorized as:
- Id—The number that is used by ClearSCADA to identify the thread.
- Desc—A description of the thread.
- Exec Count—The number of times the thread has executed.
- State—The current state of the thread.
- If the State of the thread is Waiting, the thread is healthy.
- If the State of the thread is consistently (i.e. for minutes or hours) any state except Waiting, there is a problem and you should contact Schneider Electric.
- Run Time—The total amount of time that has elapsed since the thread started.
- User Time—The total amount of time that the CPU has spent executing the thread in user mode.
- Kernel Time—The amount of time the thread has spent in the operating system.
