MongoDB dla administratora
0 likes691 views
This document discusses using MongoDB as a log collector. It provides examples of storing log data from syslog-ng in MongoDB collections, including filtering and parsing logs. It also gives examples of analyzing the log data through map-reduce to find top IP addresses and provides ideas for other uses like CAPTCHAs, error localization, and analytics.

- 13. MongoDB „Capped collections are fixed sized collections that have a very high performance auto-FIFO age-out feature (age out is based on insertion order). They are a bit like the "RRD" concept if you are familiar with that.” „In addition, capped collections automatically, with high performance, maintain insertion order for the documents in the collection; this is very powerful for certain use cases such as logging.” > db.createCollection("mycoll", {capped:true, size:100000}) > db.createCollection("messages", {capped: true, size:10000000, autoIndexId:true})
