log

Hackage version Build Status

A set of libraries that provide a way to record structured log messages with multiple back ends.

Supported back ends:

  • Standard output
  • Elasticsearch
  • PostgreSQL

The log-base library provides only the basic scaffolding and the stdout back end. Additional back ends are provided by log-elasticsearch and log-postgres.

Example

{-# LANGUAGE OverloadedStrings #-}

module Main where

import Log
import Log.Backend.ElasticSearch

main :: IO ()
main = do
  let config = defaultElasticSearchConfig {
        esServer  = "http://localhost:9200",
        esIndex   = "logs",
        esMapping = "log"
        }
  withElasticSearchLogger config $ \logger ->
    runLogT "main" logger $ do
      logTrace_ "foo"
