It does exactly what you described.
That's one option.
I use a custom system, with perl and bash scripts collecting data and
saving to rrd databases. php script displaying the images.
Using this on a box with 5 interfaces (3 ethernet, 1 openvpn tunnel, 1
ppp session).

Hello
I have a freebsdbox firewall . also I have some internet customers.
I want to save how much data they used in a table ( such as mysql
table ) for each ip address.
Apache2, php5 and mysql5.5 work on the box.
How can I do it ? any script or tool.
Thanks
How can i save in table using ntop ? is there any document ?

Read the man pages. There are sql export options that you can specify on run.
I could not see any sql options on the man file of ntop.
Where is it?
Whoops, my mistake. I was reading the NetFlow documentation and going
off vague memories of older versions of Ntop.
Ntop saves data in RRD files. There are PHP libraries to parse this
data [1]. You could theoretically scrape the RRDs and put them in a
SQL DB, but they may be useful enough on their own if you can parse
them correctly. (Note: I have never personally parsed RRDs manually.
This info was pulled from a simple Google search. YMMV.)

Here's a tricky one:
Versions: I'm using PostgreSQL 9.0.7 and PHP 5.3.8.
First, I have a table bob with two columns: bobid (integer) and bobtext
(text). The bobid field defaults to a sequence called bob_seq which is just
a simple counter (1,2,3 etc.)
I can do an INSERT query into bob:
INSERT INTO bob (bobtext) VALUES ('Hello Bob') RETURNING bobid;
and get the value the sequence has given me for bobid: this works fine using
both the psql tool and pg_query in PHP.
I can also do an UPDATE query in the same vein:
UPDATE bob SET bobtext='Hello Bob revisited' WHERE bobid=x RETURNING bobid;
where x is a valid bobid value for an existing record in the table. This
returns the value of bobid for the updated record which should be the same as
x and again it works in the psql tool and in pg_query.
Next, I have a VIEW based on bob, called fred. It is simply defined as
CREATE VIEW fred AS (
SELECT * FROM bob
);
I have two rules on fred which allow me to alter the view.
The first is used for INSERT into fred, which translates them into INSERT into
bob:
CREATE OR REPLACE RULE fred_insert AS
ON INSERT TO fred
DO INSTEAD
INSERT INTO bob (bobtext) VALUES (NEW.bobtext) RETURNING *
;
The second is used for UPDATE on fred, which translates to creating a new
record in bob and deleting the old record:
CREATE OR REPLACE RULE fred_update AS
ON UPDATE TO fred
DO INSTEAD (
INSERT INTO bob (bobtext) VALUES (NEW.bobtext) RETURNING *;
DELETE FROM bob WHERE bobid=OLD.bobid;
)
;
Note that these rules both return all of the fields of the newly inserted bob
records back up the chain to be accessible to the original query.
Now, I can insert into fred knowing that the rule will handle it:
INSERT INTO fred (bobtext) VALUES ('Hello Fred') RETURNING bobid;
and that should return the new bobid value of the inserted record (from the
bob_seq sequence). It still works in the psql tool and in pg_query.
I should also be able to exercise the update rule on fred:
UPDATE fred SET bobtext='Hello Fred revisited' WHERE bobid=x RETURNING bobid
where x is a valid bobid value for an existing record in the table.
This should insert a new row with a new bobid from the sequence and the new
bobtext value, delete the row with bobid=x, and return the bobid for the
new row.
Here's the punchline (at last):
It works in the psql tool.
It doesn't work in pg_query.

bobtext value, delete the row with bobid=x, and return the bobid for the
new row.
Here's the punchline (at last):

It doesn't work in pg_query.
?php
$result = pg_query(UPDATE fred SET bobtext='Hello Fred revisited' WHERE
bobid=42 RETURNING bobid); // Assume there is a record with bobid==42
if ($result pg_numrows($result))
{
echo pg_numrows($result).PHP_EOL;
echo pg_fetch_result($result, 0, 0).PHP_EOL;
)
?
Tells me there that although the $result resource is valid, there are no rows
and therefore no result to fetch (PHP Warning: pg_fetch_result(): Unable to
jump to row 0 on PostgreSQL result ...)
So: why is the return from the UPDATE rule different to the return from the
INSERT rule in PHP pgsql?
Thanks for taking the time...
Cheers
Pete
