Simple Python script that can convert Elasticsearch JSON output (based on Log4j events logged via Logstash) to human readable text

es2txt.py

#!/usr/bin/python

import sys
import json

jsonData = json.load(sys.stdin)

for hit in jsonData["hits"]["hits"]:
  source = hit["_source"]
  print "{0} {1:<5} - <{2}> {3}.{4}.({5}): {6}".format(source["@timestamp"], source["priority"], source["thread"], source["class"], source["method"], source["file"], source["message"])
  if "stack_trace" in source:
    print "{0}".format(source["stack_trace"])
