Abstract
Description
使用 | 利用率 | 差错 | 响应 | 解释 |
N | N | N | N | 各种情况都是正常的或者容差设置得过于宽松。 |
N | N | N | A | 如果只有响应时间是异常高的话,同时其它各种情况都是正常的,则响应延迟可能是由外部***所引起的,例如,因为外部数据库的响应过慢而使得应用程序的运行也慢。 |
N | N | A | N | 异常差错是由下游的异常差错、不合适的配置或者误触发/非法的请求所引起的。 |
N | N | A | A | 引起重试的差错也引起响应的延迟。 |
N | A | N | N | 异常低的利用率同时其它各种情况正常可以表征为“干运行”,在这种情况下,事务处理可以在不需要作任何重负载的条件下完成异常高的利用率同时其它各种情况正常则表示在资源管理配置中存在着错误,例如设置了一个10Meg的以太网而不是100。 |
N | A | N | A | 超过“拐点”的利用率会引起非线性响应下降。在这种情况下,根原因是错误配置的资源管理而不是使用所引起的。 |
N | A | A | N | 异常差错率会增加利用率,即使该使用是正常的,特别是,如果嵌入机制的重试。异常内部差错率可能是由异常高的利用率所引起的,特别是在处理应力的内部机制引起差错从而停止请求时。 |
N | A | A | A | 因为重试逻辑,异常差错率会增加利用率和响应时间 |
A | N | N | N | ***中的异常使用可以由异常外部条件所引起的最终上游异常使用所引起的。异常低使用也是有问题的症状;可能上游节点已死去。 |
A | N | N | A | 可能没有连接好。 |
A | N | A | N | 一个异常高的使用和差错率可能是一个滥用/擅自存取的指示符 |
A | N | A | A | 如果利用率是异常或者如果差错是异常的话,响应可能是一个异常。 |
A | A | N | N | 异常使用会引起异常利用率。这仍是在拐点之前,并因此不在影响响应时间或差错。 |
A | A | N | A | 如果利用率是异常的话,则响应时间可能是异常的。超过“拐点”的利用率会引起非线性响应下降。 |
A | A | A | N | 异常使用引起异常利用率和差错。这仍是在雷达的检测之下,并且还不会影响响应,但是会引起对以后响应的影响。 |
A | A | A | A | 各种情况都是异常的。这可能是特征并不是初始的或者容差设置过小。 |
