我们已经安装了 RHQ 监控系统http://rhq-project.org/display/RHQ/Home。从那时起，我们的程序开始变慢。它发生在每天上午 9:20~30。RHQ可以减慢系统速度吗？因为我们的管理员声称 RHQ 不能减慢系统速度 :)
系统包括：
- 开火 3.7.1
- JbossEAP 5.1
- PostgreSQL 9.0

如果它每天都在同一时间发生，请监视机器此时正在做什么。“top”、“vmstat”和“iotop”的输出可能是一个好的开始。

Check the different metrics that are being gathered by RHQ. One thought could be that several metrics are being gathered at exactly the same time (which happens to be 9:20) and that is causing a bit of a slow down.
Is the slow down on only one server or are you monitoring multiple servers?
