It will also detail how, when certain conditions are met, these tools initiate more complex performance tasks to monitor programs." +tags: +- eBPF +- Profiling +- Tracing +--- + +# Background + +In previous articles, We have discussed how to use SkyWalking and eBPF for performance problem detection within [processes](/blog/2022-07-05-pinpoint-service-mesh-critical-performance-impact-by-using-ebpf) and [networks](blog/diagnose-service-mesh-network-performance-with-ebpf). +However, there are still two outstanding issues: + +1. **Task initiation time**: It's often challenging to quickly determine which processes require performance monitoring when problems occur. +Typically, manual intervention is required to identify processes and the types of performance analysis necessary. +We need a faster way to detect which processes require performance analysis. +2. **Resource consumption of tasks**: When tasks are initiated, they may consume more system resources to analyze more extensive performance issues. +We need a method to manage resource consumption and understand which processes necessitate performance analysis. Review Comment: My point is, if profiling tasks are continuously started for a particular process by default, it might consume a significant amount of system resources, affecting overall system performance. Continuous analysis can help mitigate this resource consumption -- This is an automated message from the Apache Git Service.
