AQL Event and Flow Query CLI Guide

1USING THE AQL QUERY CLI

You can use the AQL Event and Flow Query Command Line Interface (CLI) to

access flows and events stored in the Ariel database. This document provides

information on accessing and using the AQL query CLI including:

•About the AQL Query CLI

•Accessing the AQL Query CLI

•Using the Describe Statement

About the AQL

Query CLI The AQL event and flow query CLI allows you to access raw flows and events

stored in the Aerial database. The AQL query CLI includes syntax that is a subset

of the SQL92 standard and provides support for two tables: events and flows.

Note: The AQL CLI does not provide support for joining tables.

The AQL Event and Flow Query CLI functions in the following modes:

•Interactive mode - Using a simple shell, you can enter queries interactively

and view the results in a standard output. At the query prompt, any valid AQL

statement is accepted. If time is not specified (using -start and -end

options), the last minute is assumed as the time range. You can also access

previous commands by using your up arrow. This is the default mode.

•Non-interactive mode - You can enter the non-interactive mode by adding the

-execute <AQL query> parameter to the command. The -execute

command must be followed by a valid AQL query surrounded by double quotes.

AQL Event and Flow Query CLI Guide

6USING THE AQL QUERY CLI

The non-interactive mode does not include a prompt allowing you to redirect the

output to a file with a regular UNIX pipe syntax. By default, the results are sent

to a standard output.

Accessing the AQL

Query CLI To access the AQL query CLI:

Step 1 Log in to STRM, as root.

Step 2 Enter the following command:

/opt/qradar/bin/arielClient

The Query prompt appears.

CLI Options Table 1-1 lists the supported CLI options:

Table 1-1 AQL CLI Options

Option Description

-range <first

record> <last

record>

Limits the number of records sent to the output within the

specified range. This is useful for viewing a selection of

records generated by an ordered query. For example, if you

wish to view the first ten records, you must specify -range 1

10.

-debug Generates debugging output during execution.

-start <time>,

-end <time> Specifies the start and end time of the query.

Where <time> specifies the time. You must specify the time

as either a UNIX timestamp or a date using the following

format: yyyy/mm/dd-hh:mm:ss.

For example:

/opt/qradar/bin/arielClient - start

2007/08/11-01:15:00 -end 2007/08/11-01:17:00

-exectime <time

limit> Specifies the maximum period of time, in seconds, a single

query may continue processing.

-execute <AQL

query> Allows you to enter non-interactive mode that allows you to

process a query that is sent to standard output. If you do not

include this option, the command is entered in interactive

mode. You must include your query in double quotes.

-f <output

format> Allows you to specify the output format for the query results.

The table format is an ASCII drawing of a multi-column table

while the CSV format provides a comma separated list.

Where <output format> indicates the output format. The

options are table or csv.

-remote

<host:port> Specifies that you wish to connect to a specific Ariel query

host and port.

AQL Event and Flow Query CLI Guide

Using a Select Statement 7

For example:

If you wish to enter a command in interactive mode:

/opt/qradar/bin/arielClient -start 2007/08/11-01:15:00 -end

2007/08/11-01:17:00 -exectime 60

/opt/qradar/bin/arielClient

/opt/qradar/bin/arielClient -start 2007/08/11-01:15:00 -end

2007/08/11-01:17:00 -f csv

If you wish to enter a command in non-interactive mode:

/opt/qradar/bin/arielClient -start 2007/08/11-01:15:00 -end

2007/08/11-01:17:00 -exectime 60 -execute "select * from flows

where sourceIP = '231.12.37.17' and protocol != 'TCP.tcp_ip'"

Using a Select

Statement You can use a select statement that includes one or more fields of a flow or event.

You can also use an asterisk (*) to denote all columns. All field names are case

sensitive, however, the terms select and from are not case sensitive. The

supported fields include:
