Real-time /proc/net TCP and UDP socket connection event logger for Linux
TCP Connection Event Logger monitors live Linux kernel socket tables (/proc/net/tcp, /proc/net/tcp6, /proc/net/udp, and /proc/net/udp6) and records a timestamped history of opened, state-changed, and closed network connections. A lightweight Linux alternative to TcpLogView for network troubleshooting, service auditing, and socket lifecycle analysis.
Key features:
- Configurable Polling Engine: Polls /proc/net TCP/UDP IPv4 and IPv6 kernel tables at configurable intervals from 250 ms to 5 seconds and diffs active socket endpoints across ticks.
- Connection Lifecycle Tracking: Logs timestamped OPENED, STATE_CHANGE (such as SYN_SENT to ESTABLISHED to TIME_WAIT), and CLOSED socket events with measured connection duration.
- UID, Inode & Process Cross-Reference: Resolves socket UIDs to local usernames, records kernel socket inodes and Tx/Rx queue depths, and maps accessible /proc/<pid>/fd descriptors.
- State Distribution & Structured Export: Renders live TCP/UDP state distribution charts and exports filtered or complete connection event logs to CSV and JSON files.
