mysql proxy issue: backend servers "State" is "Unknown"

[Mike Wong]

Not sure if anyone cares to help me or not. But I just setup mysql proxy running 0.8.3 on two mysql servers running master and slave configuration. I follow several instructions on the web to have it configured. when I used the admin monitoring to SELECT * FROM backends;

It showd that all of my backend servers are in "unknown" state:

mysql> SELECT * FROM backends;
+-------------+------------------+---------+------+------+-------------------+
| backend_ndx | address | state | type | uuid | connected_clients |
+-------------+------------------+---------+------+------+-------------------+
| 1 | 172.16.10.94:3306 | unknown | rw | NULL | 0 |
| 2 | 172.16.10.93:3306 | unknown | ro | NULL | 0 |
+-------------+------------------+---------+------+------+-------------------+
2 rows in set (0.00 sec)

Here is my config file:

# MySQL Proxy's configuration file (mysql-proxy.cnf)

[mysql-proxy]
daemon = true
proxy-address=172.16.10.45:4040
admin-lua-script = /opt/mysql-proxy-0.8.3/lib/mysql-proxy/lua/admin.lua
