This article aims to elucidate how to leverage DeepFlow's zero-code feature based on eBPF to construct an observability solution for APISIX. On this basis, it integrates the rich data sources of existing APISIX plugins to eliminate data silos and build an all-in-one platform for comprehensive observability of the APISIX gateway. Through DeepFlow, APISIX can achieve comprehensive observability from traffic monitoring and tracing analysis to performance optimization, eliminating data dispersion and providing a centralized view. This accelerates fault diagnosis and performance tuning, making the work of DevOps and SRE teams more efficient. This article will focus on how APISIX's tracing data, metric data, access logs, and performance profiling data can be integrated with DeepFlow.
