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).
|
|
