The latest News and Information on IT Networks and related technologies.
First, let me say that I know AWS doesn’t promise anything about network performance as it relates to packets. At best, they leave it as a multivariate calculus problem for the reader — inclusive of CPU performance, code optimization, MTU, and current network congestion under the VLANs. But still, I was curious to see if there was any correlation to Amazon’s published “Network Performance” and the actual packets per second metric I tested.
Rapidly increasing IT complexity, customer expectations around application availability and performance, and the importance of supporting new digital initiatives and services, taken together, are placing unprecedented demands on Network Operations Centers (NOCs) and IT Operations teams inside large, complex organizations like yours.
Remember the customer who reported a hard-coded packet per second (PPS) limit in AWS? His use case was a reverse-proxy server to a very active database cluster, complete with heartbeats, keep-alive connections, and a heavy load of queries and traffic. When the network throughput was sustained for an hour or so, the throughput would drop despite increasing demand.
A customer of ours reported a limit on number of packets in Amazon’s EC2 instances. According to the report, it didn’t happen on all instance types, and didn’t happen all the time. Also, it was unrelated entirely to bandwidth or MTU. According to the report, packet transmission rates were limited the same as CPU on t2/t3 instances — each instance earns credits which, when exhausted, cause throttling.
Today we welcome David Morris, a System Centre Engineer for one of the world's largest law firms, who has written a special guest blog about the Solarwinds community MP. A must read for anyone who has Solarwinds and Microsoft System Center Operations Manager (SCOM). We'd like to thank David for taking the time to write up this fantastic piece of content - it's another great example of the SCOM community hard at work.
“What kind of integrations do you have with PRTG?” Yesterday, one of our favourite German customers asked us that question. And today we post our answer in a blog post! And without further ado, we’ll let our technical colleague Tom Morriss take centre stage.
