Audit Parser tool can be used for querying the ozone audit logs. This tool creates a sqlite 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 [COMMAND] [PARAM] {{< /highlight >}}
To load an audit log to database: {{< highlight bash >}} ozone auditparser load {{< /highlight >}} Load command creates the audit table described above.
To run a custom read-only query: {{< highlight bash >}} ozone auditparser query {{< /highlight >}}
Audit Parser comes with a set of templates(most commonly used queries).
To run a template query: {{< highlight bash >}} ozone auditparser template {{< /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 |
