Posted How Do We Measure Computer Resources? on Application Performance Engineering Hub. It looks like an important issue for the high-tech industry for me – it is a pity that it continues to be unnoticed.
When I created my site as a collection of performance-related links and documents in 2004, I grouped links somewhat arbitrary, just to avoid “analysis paralysis”, hoping to get back soon and polish as needed. It is interesting that I haven’t changed much in grouping for these seven years (definitely many things changed, many changes are long time due, but with main grouping of information I wasn’t able to improve much). Whatever links I added, they mainly fit one (or few) existing category. And just now I realized that we have a new information category – Application Performance Management – which doesn’t fit in any existing category. I had a category for APM tools from the beginning – they were around for a while – but not for generic APM information (something beyond talking about just tool features). And finally I put together a list of great information sources into a new group, Application Performance Management:
Application Performance, Scalability, and Architecture blog from Dynatrace
Seriti Consulting Blog the Web Operations and Management Specialists, by Stephen Thair
Many of them existed for a while, but it looks like the quantity finally got into a new quality and we see a new discipline emerging (instead of a marketing term to promote a special kind of tools). It is definitely related that with new technologies, such as virtualization and cloud computing, traditional resource monitoring is not enough anymore and there is a need monitor on application and service levels. Some mentioned above blogs are from tool vendors, but they provide great content far beyond discussing the tools.
