pt-table-checksum show wrong DIFF
I'm try to use pt-table-checksum tool. I have Master/Slave tables, and I add some rows to the slave to check it.
pt-table-checksum --ignore-databases mysql S=/tmp/5.6.22_3306_Master/data/mysql.sock --user=SlaveUser --password=1234
produce this result:
TS ERRORS DIFFS ROWS CHUNKS SKIPPED TIME TABLE
07-21T16:47:35 0 0 8 1 0 0.008 test.Countries
07-21T16:47:35 0 0 0 1 0 0.006 test.Persons
When I run this query (SELECT * FROM percona.checksums WHERE db not like 'mysql';) on the slave I can see the difference:
How I can see the right result and the diff with pt-table-checksum?
Thanks!

Manual states it clearly:
If you wish, you can query the checksum tables manually to get a
report of which tables and chunks have differences from the master.
The following query will report every database and table with
differences, along with a summary of the number of chunks and rows
possibly affected:
SELECT db, tbl, SUM(this_cnt) AS total_rows, COUNT(*) AS chunks
FROM percona.checksums
WHERE (
master_cnt <> this_cnt
OR master_crc <> this_crc
OR ISNULL(master_crc) <> ISNULL(this_crc))
GROUP BY db, tbl;
The table referenced in that query is the checksum table, where the
checksums are stored. Each row in the table contains the checksum of
one chunk of data from some table in the server.
To get the actual differences, you'd need to run pt-table-sync --print and determine the changes by the SQL queries it generates.

I saw on the manual. But yet, shouldn't I see difference on the output table?

yes but with the above query you'll get the summary of chunks and estimated rows affected.
