Correlating logs to traces

Correlating Logs to Traces

Log entries sent by logpusher can be correlated with any OpenTelemetry spans / traces (if you need an easy way to generate spans and traces, try tracepusher).

Adding Trace ID and Span ID

Your OpenTelemetry platform of choice needs two pieces of information to tie the log line to the span:

  1. The span ID
  2. The trace ID

These are added as additional commands when you use logpusher:

./logpusher \
  --endpoint http(s)://OTEL-COLLECTOR-ENDPOINT:4318 \
  --content "This is my log line" \
  --trace-id "TRACE-ID-GOES-HERE" \
  --span-id "SPAN-ID-GOES-HERE"
