Collecting logs via LogDoc UDP

A lightweight protocol for high-frequency log delivery without connection setup overhead. Best for streaming telemetry, metrics and non-critical data where speed matters more than delivery guarantees.

logdoc-udp.conf

[udp]
# LogDoc server address
host = logdoc-server
port = 12345

# Packet size (65507 bytes max)
max_packet_size = 8192

# Message batching
batch_size = 100
batch_interval = 1s

# Data format
format = json

Sending with netcat

# Send a single log over UDP
$ echo '{"level":"INFO","message":"health check"}' | \
    nc -u logdoc-server 12345

# Stream logs from a file
$ tail -f /var/log/app.log | \
    logdoc-send --proto udp --host logdoc-server --port 12345

When to use UDP

•High-frequency telemetry and metrics where occasional message loss is acceptable

•Debug logging in dev/staging environments with minimal network load

•IoT devices and edge nodes with constrained resources
