seq-log-transport

Watch and ship json structured log files to seq server

Getting started

Deno must be installed on the system

deno install --unstable-kv --allow-env --allow-net --allow-read --allow-write --allow-sys -n seq-log-transport https://cdn.jsdelivr.net/gh/ball6847/seq-log-transport@b78b186/main.ts

Create a config file

sources:
- /app/logs/*.jsonl

seq:
  server: http://seq:5341
  token: your-seq-token-here

# optional watcher.interval (default: 1000ms)
# watcher:
#   interval: 1000

Run the cli

seq-log-transport -c config.yml

The log files will be watched for changes line-by-line as json and ship to destination seq server

JSON attribute format

The cli requires each log entry to contain the following field

datetime for using as timestamp, can be any value that javascript Date object accept
level any string that will be passed as log level, for example INFO, DEBUG, ERROR
message this will be passed as messageTemplate (feel free to adjust the template here)

Anything else will be passed as log properties that can be used for messageTemplate or can be used later to query the logs on Seq admin ui

TODO

implement field mappings for datetime, level and message, as this might not always be in of our control.
graceful shutdown to stop watching and flush all pending messages to seq before exit
