With the rise of Linux servers and systems, it is crucial to monitor the performance and health of our platforms. The latest version, Linux 6.13, introduces an innovative feature to track the number of suspended tasks since system startup. This new indicator brings a significant dimension to server management, providing administrators with valuable data to optimize the operation of their systems. Let’s discover together this functionality and its usefulness in a professional environment.
Understanding suspended tasks
Suspended tasks are processes that are not running as expected, either due to a missing resource or a dependency. Identifying the origin of these tasks can be complex. Thanks to Linux 6.13, it is now possible to obtain precise information on these incidents:
- Waiting time
- Committed system resources
- Potential impacts on performance
The suspended task counter
New feature introduced in Linux 6.13 allows access to a counter via virtual file system /proc/sys/kernel/hung_task_detect_count. This allows you to see the number of suspended tasks since the last startup and helps detect possible problems.
Using this counter allows:
- A quick analysis of the system status
- Better understand application performance
- Identification of hardware or software problems
