Several years back, when I was working for a company that sold high performance appliances, we received a report from a customer that performance was atrocious and nowhere near our indicated throughput by several times over. Obviously we needed to work out what was going on. To the tools mobile!
Thankfully the appliances had the ability (with the customer’s permission) to dial home to our engineering centre for us to be able to get access to the machine using a variety of tunnelling methods. Using some custom pre-installed tools we were able to verify that the appliance was configured correctly and that the level of performance that we expected was possible. However based on the statistics that the appliance collected it was obvious that the customer wasn’t seeing this performance at their install site.
We had reached the limits of our pre-installed tools designed to debug these sorts of issues, so now we had to investigate deeper.
