Audit Parser tool can be used for querying the ozone audit logs.
This tool creates a sqllite database at the specified path. If the database
already exists, it will avoid creating a database.
The database contains only one table called `audit` defined as:
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))
Usage:
{{< highlight bash >}}
ozone auditparser <path to db file> [COMMAND] [PARAM]
{{< /highlight >}}
To load an audit log to database:
{{< highlight bash >}}
ozone auditparser <path to db file> load <path to audit log>
{{< /highlight >}}
Load command creates the audit table described above.
To run a custom read-only query:
{{< highlight bash >}}
ozone auditparser <path to db file> query <select query enclosed within double quotes>
{{< /highlight >}}
Audit Parser comes with a set of templates(most commonly used queries).
To run a template query:
{{< highlight bash >}}
ozone auditparser <path to db file> template <templateName>
{{< /highlight >}}
Following templates are available:
|Template Name|Description|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|
