Kindling is an eBPF-based cloud-native monitoring tool, which aims to help users understand the app behavior from kernel to code stack. With trace profiling, we hope the user can understand the application's behavior easily and find the root cause in seconds. Besides trace profiling, Kindling provides an easy way to get an overview of network flows in the Kubernetes environment and many built-in network monitor dashboards like TCP retransmit, DNS, throughput, and TPS. Not only as a network monitor, but Kindling is also trying to analyze one detail RPC call and get the following information, which can be found in network Explore in Chrome. The usage is the same as network exploration in Chrome, with which users can tell which part to dig into to find the root cause of the problem in the production environment.
Features
- The exact thread which executed the trace span is highlighted
- Documentation available
- The logs printed by each thread are collected and correlated to the relative thread with its timestamp
- The code execution flame graph is correlated to the time series where the CPU is busy
- The network-related metrics are correlated to the time series where the network syscalls are executing
- The file-related metrics are correlated to the time series where the file syscalls are executing
