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,…

Empowers efficient database monitoring and performance troubleshooting with powerful workload analysis

I find it extremely helpful to use Foglight to triage any database issues, specifically performance issues using what Foglight calls PI investigator. It is a very powerful workload analysis tool that helps me understand where bottlenecks are. It allows me to see performance issues as end users report them. It can save time and effort when doing root cause analysis. It enables me to obtain information quicker and easier compared to manually compiling it. Foglight provides us with a near-real-time activity database. It's not 100% real-time. It has less than a minute latency. It allows us to see performance issues as end-users report them. We started seeing benefits pretty much immediately. We use Foglight to display intensive databases. However, it's not something we monitor regularly. It's only something we kind of dig into as we troubleshoot and triage issues. It does help us determine potential IT help issues. When we use Foglight, we find it helps drill down holistically into potential bottlenecks. It helps us to see what is going on in the database. Foglight allows us to monitor multiple database platforms. We use, for example, Oracle, SQL Server, Postgres, Amazon Redshift, and SAP HANA. It gives us insight into our entire landscape of production workloads in near real-time. The solution saves costs when performing root cause analysis. It can save time and effort when doing root cause analysis. It allows us to obtain information quicker and easier than by manually compiling information.

Quotes from Members

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

Pros

"The ability to go back and look at historical data is the most valuable feature."

"SQL DM made troubleshooting much easier and allowed multiple people to look into an issue with confidence."

"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."

"Monitors and alerts on our mission critical instances in real-time on a 24/7 basis."

"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."

"One of the hardest things to do in database management is to evaluate performance deviation across time. The adaptive baseline that Quest is using is by far the most helpful. That doesn't necessarily mean I use it on a daily basis, but it is something that I have not been able to find in any other tool, at the same level."

"We can visualize all the different types of DB servers that we are monitoring in a single pane of glass. It uses a 360-degree overview of the database, for each of those databases that we are monitoring. That includes what kind of resource utilization is happening and what kind of DB parameters are getting monitored, as well as the different types of DB parameters that are being offered for each database type."

"The most valuable feature is the in-depth capability SQL Performance Investigator provides. It allows you to drill down to the smallest detail that occurs on our platform. It does a highly detailed and atomic follow-up of what one wants to look for in relation to time and our different instances."

"Foglight is also able to help the DBAs proactively fix problems before they become an issue. It provides them with real-time activity screens that help in this regard. The DBAs are able to go to these screens and look at what's happening in real time, and that buys them time. It helps them see problems ahead of time and find solutions to them."

"We went from basically 30% coverage of our production environment to 100% coverage."

"Its reporting capabilities are immense."

"The alarms alert proactively if there are any potential or ongoing issues with the databases that we support. That means we can take preventive or corrective action before the issue becomes a big issue. And the SQL PI features enable us to drill down into performance issues in our databases so that we can improve performance, which is important."

"The profiler allows us to look at the profiles of the database queries that are being run over time. It allows us to go back to our customers and say that these are some of the queries causing them some headaches. It gives us the opportunity to provide suggestions on how to improve their experience."

Cons

"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."

"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."

"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."

"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."

"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."

"They can improve checking the status of the CPU, memory, and IO utilization from each task."

"When we decided to go with Foglight, a lot of people stopped using the diagnostics part because it was very intimidating... They still won't use it because they feel it's too intimidating. They will open something up and not know what to do. It's not very user-friendly. You have to click on a lot of stuff to find the information."

"It would be amazing if they could enable the "Performance Investigator" functionality across all database platforms."

"One thing that I would like, and it's probably something that I could set up internally, is something other than a dashboard which I have to look at to know that a server is down. I'd like bells and whistles to go off... If I look at the dashboard I know there's a server down. But if I'm not looking at it, if I'm looking at some other problem, I want to know about it. You can do that, you can use SMSs and alerts to your phone, and I could set it up to handle that, but it would be nice if, out-of-the-box, Foglight did that."

"I get a lot of alerts that, while important, are not critical. Then I have to dig in and figure out how to turn alerts off, but not the logging. I want to be able to go back, once we get the other big issues out of the way, and start fine-tuning some of those other areas, but I don't necessarily want to receive an email for all of them."

"The monitoring capabilities for Postgres should be at par with SQL Server. This is the area where we push back on our Quest representative."

"The monitoring capabilities for Postgres should be at par with SQL Server. This is the area where we push back on our Quest representative. We want more insights into Postgres."

"I would like the rule development code to be made available so we don't always have to be referred to professional services for custom solutions. For example, if we want to exclude certain databases from a particular rule, we shouldn't have to go to support and to professional services for that solution. If the code and syntax were available, we have resources that could quickly turn something like that around."

"The version that I'm using is not the latest version, so there might have been some improvement, but the OS monitoring is a bit lacking, and the high-availability option is a bit complicated to set up and it doesn't work all the time."

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 price of Foglight could be a little more competitive in Chile, and it should be lowered for long-time customers— at least by 20 percent. Sometimes the price is a limitation. We have seven instances and nearly 5 million users. If Quest Foglight could reduce its prices for the clients that have been with it for a long time, we would be able to have more instances."

"Compared to the other tools on the market, Foglight is okay in terms of pricing and licensing."

"Pricing is very reasonable. We were able to construct a pretty easy contract with Quest, who were very easy to work with and very amenable to what we are trying to do. It worked out well for us."

"The price is worth it, if you have the time to go through the information."

"It is cost-effective. With our EA, it is really based on the scale of our database environment. We found the Quest team to be reasonable and flexible when it comes to pricing and scaling of licenses."

"This is like the "Cadillac" of performance monitoring software. It's not cheap... I am currently with a company that I was able to convince that the product is worth the cost."
