Sometimes you would like to see how well your system is performing, but this information is hard to extract from all the data available to you. The processor usage, queue lengths and message rates, database transaction times and numbers - they do not tell the full story. You, as the developer of the system, know best what parts of the system and what processes should be monitored - and how. Youw would like to measure the number of business operations performed and time taken. But how to collect this information from multiple machines and present it in a graphical form? There are many options, however here I will show how to do this using the Seq log collector.
