Prometheus 监控思科交换机因为领导比较青睐 Prometheus 开源监控,因为鄙人自身也是网络专业出身,所以便希望能用 prometheus 监控公司的交换机,公司大量的交换机在业务区,比较繁杂,虽然日常监控都可以用 Solarwinds 和 Opmanager 进行日常网络行为监控管理,但是 Solarwinds 界面比较比较有上古世纪的感觉,Opmanager 又比较卡,对服务器硬件配置稍微高了点,而且没有比开源 Prometheus 的更方便管理、进行修改配置等操作。况且现在 prometheus 有较多的公司正在使用,可搜集的资料较多,但相对来说,监控交换机的这方面, snmp_exporter 的发展就相对较为缓慢一点,不过相信我们越来越多的人使用,终究会更加完善。
