# How to include a Binlog server setup with MaxScale SQL routers
Since MaxScale 2.2 it's possible to use a replication setup
which includes Binlog Server, MaxScale MySQL monitor and SQL routers
such as ReadConnection and ReadWriteSplit.
The required action is to add the binlog server to the MySQL
monitor server list only if _master_id_ identity is set.
Example for binlog server setup with master_id=2222
```
[BinlogServer]
type=service
router=binlogrouter
router_options=server-id=93,,,,master_id=2222
```
MaxScale configuration with SQL routers:
```
[binlog_server]
type=server
address=192.168.100.100
port=8808
[MySQL Monitor]
type=monitor
module=mysqlmon
servers=server5,server2,server1,binlog_server
```
Binlog Server is then seen as a Relay Master without the Slave status:
```
MaxScale> show servers
Server 0x65c920 (binlog_server)
Server: 192.168.100.100
Status: Relay Master, Running
Protocol: MySQLBackend
Port: 8808
Server Version: 10.1.17-log
Node Id: 2222
Master Id: 10124
Slave Ids: 1, 104
Repl Depth: 1
Server 0x65b690 (server5)
Server: 127.0.0.1
Status: Master, Running
Protocol: MySQLBackend
Port: 10124
Server Version: 10.1.24-MariaDB
Node Id: 10124
Master Id: -1
Slave Ids: 2222
Repl Depth: 0
```
If Binlog Server is monitored and no explicit identity is made by using _master_id_,
then it's not shown as a Relay Master but just as Running server and its slaves
are listed in the Master details (including binlog server id):
```
Server 0x65c910 (binlog_server)
Server: 192.168.100.100
Status: Running
Protocol: MySQLBackend
Port: 8808
Server Version: 10.1.17-log
Node Id: 93
Master Id: 10124
Slave Ids:
Repl Depth: 1
Server 0x65b680 (server5)
Server: 127.0.0.1
Status: Master, Running
Protocol: MySQLBackend
Port: 10124
Server Version: 10.1.24-MariaDB
Node Id: 10124
Master Id: -1
Slave Ids: 1, 104 , 93
Repl Depth: 0
```
**Note**: even without the _master_id_ router option, it's always worth monitoring
the Binlog Server in order to show all servers included in the replication setup.
