Offers effective monitoring of resources but lacks the ability to connect to an AWS instance and write custom queries.
We use it mainly for monitoring, including CPU, memory, and disk space, and for troubleshooting purposes We've set up alerts to notify us when performance deviates from the baseline we've configured for each resource. So, whenever that happens, we get an alert and can investigate immediately. So,…

Facilitating on-the-spot troubleshooting with detailed root cause analysis
Spotlight provides valuable features such as the ability to get alerted and drill down to a very granular level to find out where actual problems are coming from. The drill-down feature helps with isolation, root cause analysis, and determining next steps. It aids in preventing potential issues by allowing us to make correctable changes internally within SQL Server. When needed, it also helps address external influences affecting system design. Additionally, the historical data analysis is helpful for long-term capacity planning.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Monitors and alerts on our mission critical instances in real-time on a 24/7 basis."
"The best part of SQL DM is the ability to customize alerts and counters. This allows our team to find an issue then alert on the issue at a granular level."
"The ability to go back and look at historical data is the most valuable feature."
"Memory and CPU utilization features are good."
"The most valuable features are disk space projections for planning, and also the Snapshotting ability, to look back in time, to see what was going on the server at a particular time. It's basically the output of an sp_who2."
"We're able to diagnose issues prior to their actually becoming issues. Without the alerting, we wouldn't have a clue as to what was going to happen. With the alerting, it gives us a heads-up that a specific threshold has been met, and we need to take specific action."
"SQL DM made troubleshooting much easier and allowed multiple people to look into an issue with confidence."
"I consider the solution very scalable."
"Spotlight provides valuable features such as the ability to get alerted and drill down to a very granular level to find out where actual problems are coming from."
"Its dashboards are most valuable. The drill-down of the dashboards is useful."
"Spotlight provides valuable features such as the ability to get alerted and drill down to a very granular level to find out where actual problems are coming from."
"The tool is a SaaS product where I just need to type a URL and start with the design process. I can integrate all elements of source control like GitHub, GitLab, etc. The tool also supports authentication-related provisions like SSH."
 

Cons

"The initial setup gives too many user rights to the server, so you have to put a user that is part administrator's group - that's the preferred way - on each server, which is kind of a risk. You want to do least privilege and you're not doing that."
"I'm going to do an upgrade which may resolve my issues, but one area for improvement is its ability to handle the amount of data that we collect with it. We're likely one of the largest installations, with over 300 servers being collected with this product, and sometimes there are gaps. That would really be my only concern, in terms of how the data is collected and stored, for consistency."
"I would absolutely love to create customized dashboards but, unfortunately, they don't provide me the information that I need to create the report. The report I need is the detail or the transaction detail that's happening on those Snapshots. I'd like to be able to go back through time and search for things. I don't have that functionality, which is very disappointing. That's pretty bad and frustrating because I could query it and find out so much information about what's hitting my environment and when, but instead, they want control over it and to not give me that information. So it's encrypted. I can't pull it out and that is really bothersome."
"They can improve checking the status of the CPU, memory, and IO utilization from each task."
"It would helpful if SQL DM could mark when changes are made within the program."
"We don't find that it helps us with performance monitoring and diagnostics. We find that SentryOne does that better. Also, in terms of alerts, we had to customize them dramatically so that we didn't get alerted on every little thing."
"One thing I'd like to see is the ability to view the execution plan and have the system automatically recommend potential query optimizations, especially at the query level."
"One improvement could be the inclusion of suggestions for missing indexes or better analysis of how indexes are utilized and how execution plans are used, similar to what other products offer."
"One improvement could be the inclusion of suggestions for missing indexes or better analysis of how indexes are utilized and how execution plans are used, similar to what other products offer."
"Some customizations of the dashboard, such as having backup reports, would be useful."
"There's no reporting with this tool, and there really should be. They should add that into future releases."
"The software does not support webhooks. It doesn't support advanced versions of APIs. The tool also doesn't support advanced versions of specifications. The change that we do in one part of the model is not reflected throughout the specification. There are also some mutations in the clones. I am not able to do a local source control with the product as well."
 

Pricing and Cost Advice

"We were upgraded to Premium Support without their actually asking us, when we were quoted. Then I asked for Standard Support and that they had to re-quote us that. But they don't do that by default. They upcharge you by default, which I didn't think was very nice, without even asking."
"The pricing is reasonable, it's comparable with the competitors."
"The tool is cloud-based. It is priced well."
"Its cost was somewhere in the middle."
