[Twisted-Python] Announcing Eliot 0.7: Logging for complex and distributed systems (with nice Twisted support)

[Itamar Turner-Trauring]

Imagine you have a client that sends a request to a server and gets back
a 500 error. What caused it? If you're using Eliot you can trace the
logs across processes: 

$ cat server.log client.log | python eliottree.py 
e076ca50-9abc-44b2-95d8-85cf6956bc33
 +-- main at 1/started
 |-- process: client
 `-- timestamp: 2015-04-28 16:50:00.379033
 +-- eliot:remote_task at 2,2,1/started
 |-- process: server
 `-- timestamp: 2015-04-28 16:50:00.389533
 +-- http_request at 2,1/started
 |-- process: client
 |-- timestamp: 2015-04-28 16:50:00.379096
 |-- x: 8
 `-- y: 0
 +-- divide at 2,2,2,1/started
 |-- process: server
 |-- timestamp: 2015-04-28 16:50:00.389674
 |-- x: 8
 `-- y: 0
 +-- divide at 2,2,2,2/failed
 |-- exception: exceptions.ZeroDivisionError
 |-- process: server
 |-- reason: integer division or modulo by zero
 `-- timestamp: 2015-04-28 16:50:00.389724
