+/**
+ * @file mm test of mariadbmon in a multimaster situation
+ *
+ * - use mariadbmon as monitor
+ * - reset master, stop slaves, stop all nodes
+ * - start 2 nodes
+ * - execute SET MASTER TO on node0 to point to node1 and on node1 to point to node0
+ * - execute SET GLOBAL READ_ONLY=ON on node0
+ * - check server status using maxadmin interface, expect Master on node1 and Slave on node0
+ * - put data to DB using RWSplit, check data using RWSplit and directrly from backend nodes
+ * - block node0 (slave)
+ * - check server status using maxadmin interface, expect node0 Down
+ * - put data and check it
+ * - unblock node0
+ * - block node1 (master)
+ * - check server status using maxadmin interface, expect node1 Down
+ * - execute SET GLOBAL READ_ONLY=OFF on node0
+ * - unblock node0
+ * - execute SET GLOBAL READ_ONLY=ON on node1
+ * - check server status using maxadmin interface, expect Master on node0 and Slave on node1
