This is arguably the most important asset that a monitoring solution can offer, although it is also easy to overlook. Ideally, you will want to opt for a setup that is able to scale to suit the size of the server infrastructure you are responsible for.
This list from SentryOne covers a range of criteria for evaluation monitoring tools and scalability sits at the top of the agenda, signifying its significance.
Scalability is not just important in terms of allowing you to be flexible and continue to use the same monitoring solution as you add more instances and resources; it also helps out in terms of cost-effectiveness.
Analyzing wait statistics
This is a minimum requirement that you should expect to see from the best SQL monitoring tools since wait statistics are a great indicator of where problems with your database currently lie. Being able to drill down into the data and receive alerts when issues are detected will make it simpler for you to fix flaws and boost server performance.
Even if a monitoring tool is packed with impressive features and boasts of its wide-ranging capabilities, this could all be irrelevant if you cannot easily and intuitively interact with its interface.
For this reason, a well-designed dashboard and a clear, concise way of displaying analytical information and performance stats should be seen as a must-have.
It is also worth noting that the best monitoring tools all share the feature of making the interface available in a web browser, rather than requiring the use of a separate, locally installed application. This not only helps with compatibility but also means that you can keep tabs on the server and make changes from almost anywhere using any device.
Another valuable asset of a solid, reliable SQL monitoring tool is its ability to showcase how server storage is performing in real-time. This will let you check up to see if this element is behaving as it should, or whether there is some kind of bottleneck that is stifling the overall effectiveness of the infrastructure.
One additional benefit that only the top tier monitoring platforms will offer the ability to predict how your storage needs will change and grow in the future. This allows you to make assessments of when it is best to invest in upgrades so that problems will not emerge as you reach the limit of your current capacity.
The responsiveness and consistency of your SQL database will be partly determined by how well optimized your indexes are, and regular defragmentation is a part of ensuring that this is handled adequately.
With the right monitoring software, you will be able to defragment indexes with ease while not needing to rely on some separate software solution to take care of this important duty.
Resolving deadlocks is another primary part of a DBA’s role, so choosing a monitoring suite that can automate aspects of this will make a lot of sense.
