Tcpdump for Everyone – Debugging Network Issues With Pcap-Release
Network issues can be hard to track down. This is especially true on distributed systems like Cloud Foundry, where apps are spread across multiple hosts and networks. Investigating such problems usually requires operator-level access to the platform, which makes it hard to scale and expensive. In this talk, we present "pcap-release", a solution that allows app developers to capture ingress and egress traffic of their apps across all app instances with an easy-to-use CLI. The tool also allows capturing network traffic from BOSH deployments for operators. The resulting pcap files can then be opened in popular tools like Wireshark for further analysis.
The goal of this talk is to gain community awareness and collect valuable feedback. We feel that the pcap-release project can provide lots of value to Cloud Foundry, because it makes it very easy for both operators and developers to capture network traffic from multiple hosts without any overhead.
