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.

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,…

Lets you know when your jobs are taking longer than average and allows you to go back in history and find out what was happening at certain times
To be able to go back in history and find out what was happening at certain times is the most valuable feature of the product. Another thing that's good about the product is that it will let you know when your jobs are taking longer than average so that you can foretell that there's going to be an issue coming up. Your SQL agent job is taking longer.

Quotes from Members

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

Pros

"The PI module allows [my colleague] to identify which new indexes or modified indexes are going to make the biggest impact."
"The ability to monitor multiple database platforms streamlines our database operations. The single pane of glass is what we were really after when we picked Foglight. We knew we wanted something that could monitor cross-platform because it does save a lot of time to use the same tool. The one thing that I like with Foglight is that we don't have to install anything locally, like agents, directly on the database servers. That was also a big seller because it simplifies things."
"Foglight's Change Tracking capabilities are another huge feature. It is wonderful to be able to do that. People don't realize the amount of information that Foglight gathers from a given server or instance. It gets down to the version of SQL, the disk array, everything that's there. Any change that's made, any upgrade to SQL, shows up on the dashboard almost immediately. You don't know how much time you save just having a tool in your back pocket that does that for you."
"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."
"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."
"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."
"The real-time activity screens are also helpful... if there is something that is running slowly, we can eliminate the database as being an issue and perhaps look at the server, network activity, or something outside of the realm of the database as being the issue."
"Its reporting capabilities are immense."
"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."
"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."
"The ability to go back and look at historical data is the most valuable feature."
"Memory and CPU utilization features are good."
"SQL DM made troubleshooting much easier and allowed multiple people to look into an issue with confidence."
"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."
"Monitors and alerts on our mission critical instances in real-time on a 24/7 basis."
"This solution has identified blocking, deadlock, memory pressure, and high CPU consumption issues."
"To be able to go back in history and find out what was happening at certain times is the most valuable feature of the product."
 

Cons

"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."
"Foglight does have a component that allows you to look at things in real time, but it's not as friendly or as efficient in terms of responsiveness as Quest Spotlight is. Foglight might be lacking in this department."
"Quest must release a Spanish version. That's critical because not everyone speaks English in Latin America. It's an excellent product, so it's super important that they offer the application and customer service in Spanish."
"The data model needs improvement when it comes to creating custom reports. That is an area where it needs a bit of improvement. Foglight gathers a lot of information around our databases as part of its monitoring. While I know all this information is in there, trying to pull the metric we want out for custom reports is sometimes hard to find. One nice thing about Foglight is that you can create custom dashboards, which you can easily convert to reports. We would be doing a lot more of that if it weren't for the challenging data model."
"The system is not that stable. We have been facing a lot of issues. We built a new store environment of Foglight, an environment for monitoring the Lowe's store servers, which are all Db2 servers. The objective is to monitor 800 Db2 servers in each Foglight instance. Up to 150 Db2 servers, the environment was working fine. The moment it crossed 150 or 160, we started having a lot of stability issues."
"The monitoring capabilities for Postgres should be at par with SQL Server. This is the area where we push back on our Quest representative."
"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'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."
"They can improve checking the status of the CPU, memory, and IO utilization from each task."
"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."
"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."
"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."
"It would helpful if SQL DM could mark when changes are made within the program."
"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."
"If we can get details on wait types from system views, it will help identify a more detailed root cause."
"There could be some more metrics on the high availability to let us know when there are issues synchronizing between the hosts."
 

Pricing and Cost Advice

"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."
"The price is worth it, if you have the time to go through the information."
"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."
"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."
"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."
"Compared to the other tools on the market, Foglight is okay in terms of pricing and licensing."
"The pricing is reasonable, it's comparable with the competitors."
"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."
"It's fairly expensive."
