Monitoring has reduced downtime and now enables proactive alerts across cloud workloads
When it comes to the improvement of LogicMonitor, I think there are a few points that can be improved. The first one is alert tuning, which takes time. It requires effort when trying to understand it for the first time. The defaults do not always match our workload patterns, so I have to adjust the thresholds to reduce noise and avoid alert fatigue. While the dashboards are solid, I sometimes wish that the UI was a bit more intuitive when drilling down quickly during an incident. There are many options and finding the exact view where I can identify the exact problem takes a few extra clicks. When an alert comes and I click on a LogicMonitor alert, it takes time to understand what the alert actually is and to go through the data points. The alert page specifically could be better. The alert tuning part can also be made more simple. The first area that could be better is alert clarity and routing. Sometimes alerts do not include enough immediate context, so I still have to spend a few minutes correlating data across views. Adding more actionable details directly in the alert would make the response even faster. LogicMonitor sometimes gives false alerts as well. For example, if an EC2 instance is down, it will not determine whether the EC2 instance has been deliberately turned off or if it is actually not responding. At that time, it will give false alerts. The clearing of alerts is also an issue. Once an issue is fixed, the alert should be cleared, but it takes a little time for that alert to be cleared. Another improvement that would be helpful is simpler customization for complex dashboards. It is powerful, but building highly tailored dashboards, especially across multiple environments, can feel heavy and time-consuming. I would also appreciate a stronger out-of-the-box AWS correlation, such as automatically grouping related issues across EC2, EBS, and ALBs in a way that reads as a single incident story. This would reduce the mental overhead during outages. Grouping incidents together, such as all the EC2 alerts, all the EBS alerts, or all the load balancer alerts would be beneficial. Overall, none of these are blockers, just some improving areas. There could be smarter anomaly detection out of the box that can catch unusual but important behavior without manual tuning of every threshold. Better tagging and dynamic grouping for EC2 instances would also be helpful. Cleaner alert de-duplication so a single underlying issue does not generate multiple redundant alerts would improve the system. More guided root cause workflows would be beneficial, such as providing the most likely causes based on correlated metrics. Faster search navigation across devices, dashboards, and alerts during incidents would also improve the platform.

A suitable choice for unified and efficient infrastructure monitoring across diverse environments providing user-friendly GUI, cost-effectiveness, and versatility
We use it for this specific client, they've deployed multiple instances of it across various locations to facilitate monitoring. To effectively monitor their infrastructure, it seems necessary to implement additional monitoring solutions for all three types of devices they have Nagios Fusion…

Quotes from Members

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

Pros

"Having a suite of modules that do all the work for you rather than having to set up loads of things yourself and it be there straight away ready to go is mind-blowing."
"The solution’s overall reporting capabilities are pretty powerful compared to ones that I have used previously. It seems like it has a lot of customizations that you can put in, but some of the out-of-the-box reports are useful too, like user logon duration and website latency. Those type of things have been helpful and don't require a lot of, if any, changes to get useful content out of them. They have also been pretty easy to implement and use."
"It is a really solid tool for the on-premises, physical and virtual infrastructure; I have had nothing but good things to say about it, and it has been a pleasure using it for those use cases."
"LogicMonitor has positively impacted our organization by especially improving service reliability and user experience, and the dynamic alerting and root cause analysis have helped us fix issues before they cause a full-blown outage or degrade performance for end users."
"LogicMonitor improved on-premises infrastructure monitoring in several ways. One key feature was dynamic resource allocation, although we didn't utilize it much in our system. The main functionalities we benefited from were email alerts, network mapping, and dashboards."
"LogicMonitor really improved our workflow as a company."
"One thing that's very valuable for us is the technical knowledge of the people who work with LogicMonitor. We looked at several products before we decided to use LogicMonitor, and one of the key decision-making points was the knowledge of the things that they put in the product. It provides real intelligence regarding the numbers that you see on the product, which makes it easy for us technical people to troubleshoot. Other products don't provide you with such information. You see a value going up, but you don't know what it means. LogicMonitor provides such information. For instance, if a value goes up, it says that it is probably because your disk area was too low."
"LogicMonitor is good for getting a full view of your topologies. They have LiveMaps, which give you a visual representation of your infrastructure."
"Nagios Fusion version 12.8 excels in user-friendly GUI design, cost-effectiveness, and ease of deployment."
"Being open source lets us customize it for our monitoring needs, saving us money."
"It's very easy to manage and monitor it."
"It is easier for client installation, and the configurations are doable even for a newcomer in the field."

Cons

"The topology mapping is all based on the dynamic discovery of devices that could talk to each other. There is no real manual way that you can set up a join between two devices to say, "This is how this network is actually set up." For example, if you have a device, and you're only pinning that device and not getting any real intelligent information from it, then it can't appear on the map with other devices. Or if it can appear, then it won't show you which devices are actually joined to it."
"Role-based permissions could be better and updating modules could be smoother."
"We are working with LogicMonitor to get flexibility to see the absolute running numbers, rather than doing an average. They can keep the average for customers who want it, but there should be a way to at least show the real numbers, which are coming every second on the screen."
"The ease of use with data source tuning could be improved. That can get hairy quickly."
"We would like to see more functionality around mapping of topologies, in terms of networks."
"LogicMonitor has a very steep learning curve."
"The dashboards can be improved; they are good, but there is a pain point, because to show things to management, to explain pain points to other customers, and to show them exactly where we can do better, the dashboarding could be better."
"One thing I would like to see is parent/child relationships and the ability to build a "suppression parent/child.""
"Nagios Fusion should include a 'remember me' option when logging in, so we don't need to enter a username and password every time."
"Nagios Fusion should include a 'remember me' option when logging in, so we don't need to enter a username and password every time."
"There are some bugs, although not that many. There are some situations where the solution is not stable but the number of problems is not very high."
"Adding application performance monitoring to the product alongside infrastructure monitoring would make it a more complete and useful solution."
"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."
"There are some bugs, although not that many. There are some situations where the solution is not stable but the number of problems is not very high."
 

Pricing and Cost Advice

"It's affordable. The price we get per license is a lot cheaper than what we were getting with some of the other tools. There are other monitoring tools out there that are cheaper, but what you get with LogicMonitor, out-of-the-box, makes it worth the cost."
"The license is annual, and I'm not fully aware of what it costs. We have a through-cycle that we go through, and they've been generous with us going above our limit. They're not strict on it. At the end of the year, they got us to renew. We always add some cushion for what we expect. Also, if you need custom monitoring or design work, you can pay them for consulting services."
"We pay for the enterprise tech support."
"We are on an enterprise license plan, we are paying $7.75 per device a month. That is for a commitment of 350 devices. Anything that is over the 350 is charged at 1.2 times the rate; 1.2 times $7.75 would be the overage charge. We are looking at increasing our commitment to either 450 or 500 devices. It changes our pricing if we go to 450 devices, bringing it from $7.75 down to $7.70. If we go for 500 devices, it brings it from $7.75 down to $7.50. We will probably factor in the volume discount drop from $7.75 to $7.50 in our decision of whether we uplift or not. We also have some cloud monitors, which are about $500 a month."
"In terms of pricing, I would rate LogicMonitor four out of five."
"The tool's pricing falls into the middle range."
"It's an enterprise-grade solution and competitively priced compared to the other solutions that are out there... Our organization is not huge, but LogicMonitor is worth every penny that we pay for it. I've never heard anyone say, "I'm not sure that we're getting good value for money from this product." It's integral to our business."
"The solution is not expensive."
"The pricing is quite reasonable, especially when compared to the broader market."
