阿里云API监控

使用阿里云API-SDK获取阿里云Redis的监控指标

    print(json.loads(monitor_history).get(start_time).get(metric)) # start_time


if __name__ == "__main__":
    get_metric('Keys')  # Key总数量，即实例存储的一级Key总数。Counts
    get_metric('CpuUsage')  # CPU使用率。%
    get_metric('InFlow')  # 入流量速率。KBps
    get_metric('OutFlow')  # 出流量速率。KBps
    get_metric('UsedMemory')  # 数据占用的内存。Bytes
    get_metric('memoryUsage')  # 内存使用率。%
