The Solution Rating System
|
|
| With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating. - The Grade of the Solution
- The Zone Rank of the Expert Providing the Solution
- The Number of Author and Expert Comments
- The Number of Experts Contributing
- The Feedback of the Community
Your Input Matters Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site. If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support. Thank you! |

Asked by FerrousHombre in Computer Servers, Probability & Statistics
I need to come up with 4-6 metrics (charts, essentially) that will help our organization monitor the "health" of a system that processes large amounts of data. This system is mission critical, and issues on it tend to cascade out to connected systems, so metrics that would indicate an imminent failure of some kind or a significant trend toward a resource bottleneck would be a big plus. I've found some metrics examples online by digging through a lot of irrelevant chaff, but I'm uncertain how informative they would be. The system is comprised of servers arranged in complementary pairs (#1's load fails over to #2, #3 fails to #4, etc.) with some minor load balancing, and the system as a whole pulls data in through queues, processes it, then sends it out to other systems.
Any suggestions?
Please indicate what type of charts or metrics you use, how long you've used them, and how informative or helpful you feel they have been.
