comment syslog-ng mongodb plugin configuration
MongoDB itself will have some options along those lines in 2.6 but not sure if there is any way to translate what is currently there for syslog. You can see the options in this (complete) feature request already in the 2.5.2 dev release: jira.mongodb.org/browse/SERVER-7965

comment How good is this MongoDB/EC2 setup?
Map Reduce will generally be a read on the database, and as to how much of the data will be read in, that will depend on how specific you make the query that feeds it - if you don't use criteria (like last 15 minutes based on a timestamp or similar) then it will run over all the data and likely be horribly slow (even if indexed). If you are selective and have the aforementioned timestamp field indexed, then you are more likely to see decent performance. There are too many variables to say one way or another here - I would recommend testing on a reasonable sample set first to get a baseline

comment How good is this MongoDB/EC2 setup?
Again, it would generally depend on the working set size, not the on-disk storage - I have seen single nodes with terabytes of data, but a working set that is significantly slower. It's all about the amount of the data you are trying to pull off the disk and how quickly you want to do that - storage concerns in terms of volume are purely a matter of making sure you have enough disk to store the data you want. Asking if a database can handle X data is about the same as asking if an OS or a filesytem can handle X data - unless you are hitting a limit it's really not a meaningful question.
