# fluent-plugin-mongo-slow-query

It will be helpful to find out the slow operations of MongoDB and ayalyze the query prototype.

The usage is almost same as **in_tail**.

```$ fluent-gem install fluent-plugin-mongo-slow-query```

## Configuration

```

    type mongo_slow_query

    path /path/to/mongodb/logfile

```

## Description

- **time** local time of host that the MongoDB instance is running on

- **op** operation, for example: query update remove getmore command

- **ns** namespace, concatenation of the database name and the collection name

- **detail** the deatils of operation

- **query** the prototype of query, it is an empty string when *op* is command

    for example:

    { ts: { $gt: 1411029300, $lt: 1411029302 } => { ts.$gt, ts.$lt }  

    it's convenient to statistics the similar slow queries with the same prototype and build indexes

- **ms** time used, unit: millisecond

- **nscanned** number of documents scanned

- **nmatched** number of documents matched

- **nmodified** number of documents modified

- **reslen** response length
