将 Tomcat access log 记录到 MongoDB 的插件：Tomcat Mongo Access Log
Tomcat Mongo Access Log 是一个将 Tomcat access log 记录到 MongoDB 的插件。
使用方式和Tomcat自带的AccessLogValve基本一致，只需要简单配置就能够实现将日志存入到mongodb的功能。
例子（替换掉server.xml中原来的AccessLogValve配置）：
<!-- <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="localhost_access_log." suffix=".txt" pattern="%h %l %u %t "%r" %s %b" /> --> <Valve className="chanjarster.tomcat.valves.MongoAccessLogValve" uri="mongodb://url/to/mongodb" pattern="all" />
Attributes
MongoAccessLogValve supports the following configuration attributes of AccessLogValve :
- condition
- resolveHosts
- conditionIf
- excludes
- pattern. A little different from
AccessLogValve, see below - requestAttributesEnabled
And some attributes differs from AccessLogValve:
| Attribute | Description |
|---|---|
| uri | MongoDB's uri (See MongoClientURI API) |
| dbName | Which DB to store logs, default is tomcat |
| collName | Which collection to store logs, default is tomcat_access_logs |
| excludes | Default is ".js,.css,jpg,.jpeg,.gif,.png,.bmp,.gif,.html,.htm". Don't log the URI request matches some pattern |
| rotatable | If rotatable is on, MongoDBAccessLogValve will try to create a capped collection with the size of capSize(default is 1024, in megabytes) if the collection is not exist |
| capSize | The size of capped collection, in megabytes |
| rotateCount | Not supported |
| recordError | Default is true. MongoAccessLogValve will store exception stack traces in error key when exception throws |
Collection Indexes
While it's hard to determine which fields should be indexed, but MongoAccessLogVavle provide the following indexes when it creates the Collection, so the query performance is not guaranteed. May be it's better to determine how to create index by yourself.
{ sessionId : 1} { datetime : -1} { user : 1} { statusCode : 1} { elapsedSeconds : 1} { elapsedMilliseconds : 1} { bytesSent : 1} { url : 1} { method : 1} { url : 1, datetime : -1} { user : 1, statusCode : 1} { user : 1, datetime : -1} { user : 1, sessionId : 1, statusCode : 1, datetime : -1} { user : 1, sessionId : 1, url : 1, statusCode : 1, datetime : -1} { sessionId : 1, datetime : -1} { sessionId : 1, statusCode : 1} { sessionId : 1, statusCode : 1, datetime : -1} { sessionId : 1, url : 1, statusCode : 1, datetime : -1} Patterns
All the pattern of AccessLogValve are supported while MongoAccessLogValve save them in a JSON form.
| Pattern | Key | Description |
|---|---|---|
| %a | remoteIP | See AccessLogValve (doc) |
| %A | localIP | See AccessLogValve (doc) |

| %s | statusCode | See AccessLogValve (doc) |
| %S | sessionId | See AccessLogValve (doc) |
| %t | datetime | See AccessLogValve (doc) |
| %t{format} | datetime | Same effect as %t |

| %P | params | All the GET and POST parameters, value is in the form of { param1 : value1, param2 : value2, params3 : [value1, value2, value3] } |
| %{xxx}i | requestHeaders | Request headers { header1 : value1, header2 : value2}. See AccessLogValve (doc) |
