My bandwidth to ISP is not stable, sometimes fast, simetimes slow.
I need to isolate the network by connecting directly from ISP router to my laptop only but for the moment the bandwidth is normal.
Is there any open source network monitoring software or tool that can send me and alert if download bandwidth is less than xx Kbytes/sec ?
My issue is sometimes I get 20 Mbps , sometimes 5Mbps (from particular site which doesn't have bandwidth throttling set or limit) hence I wanna get notified as soon as bandwidth slow down to 5Mbps.
So that once I get notified by email alert that bandwidth to xxx.xxx.xxx.xxx site slow down to 5Mbps, I can isolate the network to find out what is causing.
