1、 1. F5设备关键信息采集1.1 CPU占用率获取命令行：#tmstat在最顶上已行即是CPU占用率通过SNMP系统进行获取的方式采集以下值total cycles (sysStatTmTotalCycles - .1.3.6.1.4.1.3375.2.1.1.2.1.41)idle cycles (sysStatTmIdleCycles - .1.3.6.1.4.1.3375.2.1.1.2.1.42)和sleep cycles(sysStatTmSleepCycles-.1.3.6.1.4.1.3375.2.1.1.2.1.43). 大约每隔10秒钟执行一次以上采集动作2. 对每一个值，
2、计算其增量针对两次获取到的结果，示例如下DeltaTmTotalCycles = sysStatTmTotalCycles2 - sysStatTmTotalCycles1DeltaTmIdleCycles = sysStatTmIdleCycles2 - sysStatTmIdleCycles1DeltaTmSleepCycles = sysStatTmSleepCycles2- sysStatTmSleepCycles13然后根据以下公式计算CPU利用率：CPUusage=(DeltaTmTotalCycles - (DeltaTmIdleCycles +DeltaTmSleepCycle
3、s) / DeltaTmTotalCycles) *100最终的CPUusage则为该时段的平均CPU占用率。1.2 内存占用率的获取命令行：#b memory显示结果的第一行包括系统的总内存数量和当前已经使用的内存数量SNMP：通过OID sysStatMemoryUsed (.1.3.6.1.4.1.3375.2.1.1.2.1.45) 获取测试命令及输出：rootbigip4:Active config # snmpwalk -c public -v2c localhost -On .1.3.6.1.4.1.3375.2.1.1.2.1.45.1.3.6.1.4.1.3375.2.1.1
