The ":header" variable is hex-encoded since it can be binary. So, the regex needs to match that. Since "timestamp_ns" is a string and not a number, a "timestamp-format" of "%9" should be used instead of "timestamp-divisor". Related to #1613

Sorry for the delay, thanks for kicking this off. I've pushed a change that seems to get this working. It actually took me a bit of time to figure out why the format was not working. I'll try to spend a bit of time to improve error messages. |

Summary
Motivation
relative issue: #1600
The OpenTelemetry Collector's file exporter writes log records in batched JSON Lines format, where each line contains multiple log records nested under
resourceLogs.This makes it difficult to analyze with lnav without preprocessing.
Changes
src/formats/otel_collector_log.json: Log format definition with field mappings for OTEL log records (timestamp, severity, trace_id, span_id, service.name, etc.)src/scripts/otel_collector_log-converter.sh: Converter script usingjqto flatten batched records into one-per-line formattest/logfile_otel_collector.jsonl: Test data covering various scenarios (multiple services, all severity levels, edge cases)Test plan
make checkpasseslnav -n test/logfile_otel_collector.jsonlDependencies
Requires
jqto be installed for the converter to work.
