Defending Network Performance [#APM / @CompuwareAPM]

The view from the network provides both context & accuracy relative to performance & availability problems in your environment

Defending Network Performance with Packet Level Detail

My favorite war room accusation is: "It's always the network at fault!" Whether you're the one taking the blame or the one pointing the finger likely has everything to do with which seat you occupy in that war room. I suppose that comes with the territory, because at the same time there seems to be a consensus that the network is vital to understanding that holistic "Big Picture" on how application delivery is experienced by your end users. I suppose we'll have to live with those accusations, but we don't have to take the blame. Here's how you can defend yourself.

The view from the network provides both context and accuracy relative to performance and availability problems in your environment. Collecting a combination of network-based performance information and data obtained from points in the application delivery chain will provide you with the fastest path to the root cause of an issue. This collective view coupled with fault domain isolation analytics will point you to the areas to focus on. Some application problems require a deeper view that might look into the application logic and execution, while others with a network focus require that same level of detail but at a packet level. Knowing how and when to determine this quickly is the key to minimizing the impact.

Conventional wisdom will tell you that back in the "olden days" this was easy because there were certain inalienable truths:

  • Networks were slower
  • Traffic volumes were lower
  • Applications were less complex.

If only that was the case today!

Packet Level Data Is the Key
Packet level data is often sought out as the source of the truth; however, in practice this is often believed to be unobtainable. The best available approach, it would seem, is to summarize that data. But as network engineers we know that summarizing data is not going to give us what we need. Since by either summarizing or selectively sampling at this level you're very likely to either miss the key packet or at best blend contributing factors - "the packets never lie." And that's exactly what's needed to obtain definitive proof.

If we believe that the answer lies in that packet level data, then our objective should really be to provide that packet level data, even when faced with the growing complexities and obstacles that impede the traditional approaches.

The first issue is one simply of load. The increase in interface speeds coupled with the sheer amount of data in flight these days means that simply setting a packet collector into a promiscuous mode on the network will at best present you with extremely large amounts of data. Then, assuming you can collect everything, it requires significant effort and time to even locate the conversation and find the packet conditions of interest.

The trick to overcoming large quantities of data is to capture packets specifically in the context of the conversation (e.g., source and destination) that you're investigating.

Using a "high-level" report view allows you to "frame" the traffic of interest.

Right Packet at the Right place at the Right Time
The next issue is collecting the packets at the right points in the transmission path. After all, one of the reasons you might be looking at the packet level is to understand the inflight packet and traffic behavior.
