审计解析器工具用于查询 Ozone 的审计日志。它会在指定的路径下创建一个 sqlite 数据库，若数据库已存在则不再创建。

这个数据库只包含了一个名为 `audit` 的表，定义如下：

CREATE TABLE IF NOT EXISTS audit (
datetime text,
level varchar(7),
logger varchar(7),
user text,
ip text,
op text,
params text,
result varchar(7),
exception text,
UNIQUE(datetime,level,logger,user,ip,op,params,result))

用法：
{{< highlight bash >}}
ozone auditparser <数据库文件的路径> [命令] [参数]
{{< /highlight >}}

将审计日志加载到数据库：
{{< highlight bash >}}
ozone auditparser <数据库文件的路径> load <审计日志的路径>
{{< /highlight >}}
Load 命令会创建如上所述的审计表。

运行一个自定义的只读查询：
{{< highlight bash >}}
ozone auditparser <数据库文件的路径> query <双引号括起来的 select 查询>
{{< /highlight >}}

审计解析起自带了一些模板（最常用的查询）

运行模板查询：
{{< highlight bash >}}
ozone auditparser <数据库文件的路径 template <模板名称>
{{< /highlight >}}

Ozone 提供了以下模板：

|模板名称|描述|SQL|
|----------------|----------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------|
|top5users|Top 5 users|select user,count(*) as total from audit group by user order by total DESC limit 5|
|top5cmds|Top 5 commands|select op,count(*) as total from audit group by op order by total DESC limit 5|
|top5activetimebyseconds|Top 5 active times, grouped by seconds|select substr(datetime,1,charindex(',',datetime)-1) as dt,count(*) as thecount from audit group by dt order by thecount DESC limit 5|
