This helps to keep the system responsive by not blocking the top -half for too long, which could lead to missed interrupts. - -Monitoring `/proc/softirqs` is useful for: - -- **Performance tuning**: A high rate of softirqs could indicate a performance issue. For instance, a high - rate of network softirqs (`NET_RX` and `NET_TX`) could indicate a network performance issue. - -- **Troubleshooting**: If a system is behaving unexpectedly, checking the softirqs could provide clues about - what is going on. For example, a sudden increase in block device softirqs (BLOCK) might indicate a problem - with a disk. - -- **Understanding system behavior**: Knowing what types of softirqs are happening can help you understand what - your system is doing, particularly in terms of how it's interacting with hardware and how it's handling - interrupts. - - - - -This collector is supported on all platforms. - -This collector supports collecting metrics from multiple instances of this integration, including remote instances. - - -### Default Behavior - -#### Auto-Detection - -This integration doesn't support auto-detection. - -#### Limits - -The default configuration for this integration does not impose any limits on data collection. - -#### Performance Impact - -The default configuration for this integration is not expected to impose a significant performance impact on the system. - - -## Metrics - -Metrics grouped by *scope*. - -The scope defines the instance that the metric belongs to.
