数据库性能工具

    使用方法

    在下面的例子，sdbtop 使用配置文件为“/opt/sequoiadb/conf/samples/sdbtop.xml”，监控主机名为 hostname1，端口服务名为 11810，用户名为 test，密码为 test 的数据库集群中的一个节点。

    接着进入主窗口：

    1. refresh= 3 secs           sdbtop 1.0       snapshotMode: GLOBAL
    2. displayMode: ABSOLUTE     Main Window      snapshotModeInput: NULL
    3. hostname: hostname1                        filtering Number: 0
    4. servicename: 11810                         sortingWay: NULL sortingField: NULL
    5. usrName: test                              Refresh: F5, Quit: q, Help: h
