Before using this handler for logging you will need to create a capped collection on the mongodb server.
You can do this using the following commands in the mongo shell:
> use mongolog
> db.createCollection('log', {capped:true, max:100000})
... and you are ready. Running stats() on log collection should show something like this:
> db.log.stats()
{"ns" : "mongolog.log" , "count" : 0 , "size" : 0 ,
"storageSize" : 8192 , "nindexes" : 0 , "capped" : 1 ,
"max" : 10 , "ok" : 1}
import logging
from mongolog.handlers import MongoHandler
log = logging.getLogger('demo')
log.setLevel(logging.DEBUG)
log.addHandler(MongoHandler.to(db='mongolog', collection='log'))
log.debug('Some message')

"Mongo is a high-performance, open source, schema-free document-oriented database."
It can eficiently store arbitrary JSON objects. You can read more at http://www.mongodb.org/
- MongoDB inserts can be done asynchronously
- old log data automatically LRU's out thanks to capped collections
- it's fast enough for the problem
- document-oriented / JSON is a great format for log information
