Network application performance monitoring: Storage to the user
This article is part of the October 2011 Vol. 2, No. 5 issue of Network Evolution
The bitter truth of application performance management is that mitigating performance problems can be easier than identifying them. Many organizations deploy application delivery optimization (ADO) tools and compression or application acceleration to improve application performance based on user complaints (read: “Help! Our file shares don’t work!”). But WAN-level performance problems can mask the underlying difficulty of proactively identifying such problems. And, of course, if the performance problem is rooted deeper in the data center, WAN-level fixes will not help. The answer to being proactive lies in a patchwork of application performance monitoring tools that will start at storage I/O and provide visibility at every step on the network to the remote end user. Application performance monitoring in the SAN: What you need to watch In the SAN, systems both read and write blocks of data from and to bulk storage. IT professionals should be watching a few basic metrics related to application performance, chiefly I/O operations ...
