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

"LogicMonitor gives us visibility into issues that we didn't even know existed."
"LogicMonitor basically gives you the ability to monitor the infrastructure side of your application ecosystem."
"We have very fine-tuned alerting that lets us know when there are issues by identifying where exactly that issue is, so we can troubleshoot and resolve them quickly. This is hopefully before the customer even notices. Then, it gives us some insight into potential issues coming down the road through our environmental health dashboards."
"LogicMonitor helped reduce the length of an outage of a facility because of the identification of a fiber cut, so my company was able to be on top of that faster, so in that respect, the product gave us less than one year's worth of ROI."
"The concept of developing a dashboard template for ourselves, then cloning it for every single customer, and only having to change one piece of information, is a godsend. That's one of the strengths. We can develop a template that fits every customer and just change the information that is presented."
"Because we are now a structured managed services organization using one common platform for observability, we have seen significant benefits from using LogicMonitor."
"Whenever we reach out to our customers, we give LogicMonitor as a dashboard to them so they don't need to monitor the hardware side separately. For example, if my service is running on their hardware X, that means they don't need to monitor hardware X and our services too. LogicMonitor has the capability of monitoring their hardware as well as our services. This is how LogicMonitor helps us."
"What I appreciate about LogicMonitor is that it has a number of data sources and data points, which they call LogicModules."
"Nagios Fusion version 12.8 excels in user-friendly GUI design, cost-effectiveness, and ease of deployment."
"It is easier for client installation, and the configurations are doable even for a newcomer in the field."
"It's very easy to manage and monitor it."
"Being open source lets us customize it for our monitoring needs, saving us money."
 

Cons

"This is one thing that is a pain and flaw with LogicMonitor."
"Reporting limitations exist with the product. When trying to create a dashboard that is useful for day-to-day monitoring, the native reporting is not that intuitive."
"If you only want to use LogicMonitor in the cloud, there's a better tool available."
"LogicMonitor's reporting capabilities definitely could use an improvement. We have made do with the dashboarding and done what we can to make that work for our customers. However, there are definitely customers who would like a PDF or some kind of report along those lines, where we have been utilizing other tools to provide them. The out-of-the-box LogicMonitor reporting is the only thing that we have been less than impressed with."
"The reporting capabilities are within average."
"I'd like to see more automation in the tool, especially around remediation."
"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 main area for improvement is that if LogicMonitor's UI were a bit more user-friendly, that would be more useful."
"Nagios Fusion should include a 'remember me' option when logging in, so we don't need to enter a username and password every time."
"Adding application performance monitoring to the product alongside infrastructure monitoring would make it a more complete and useful solution."
"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."
"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."
 

Pricing and Cost Advice

"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."
"The tool's pricing falls into the middle range."
"I know we are saving at least several hundred thousand dollars in that we're not buying Cisco Prime."
"It can handle scaling. It is like any other cloud service. There is a cost associated with scaling, so we currently don't monitor all of our environments. We monitor just the customer-facing production environments. It would be nice if we could monitor our dominant environments, but we will have to pay a lot more due to the scaling issue. So, there's a balance there between what we would like and what we are willing to pay for."
"As a managed services provider, the licensing model that LogicMonitor provides us is excellent. We are able to scale up and scale down as needed. The pricing is reasonable for the amount of features and support that they provide."
"We have definitely seen ROI with LogicMonitor. We used to provide 24/7 IT support for our users. We have since been able to change to operating just within normal business hours for IT support, and LogicMonitor was a large part of being able to accomplish that."
"It is pretty expensive, but we now need one less full-time engineer. With on-prem, we used to have one more engineer in our department. That engineer has now moved to another department. Our capacity is better with this product than the previous one. It is easy for us to manage the sites. You have to choose between the standard account and the premium account. With the premium account, you get a lot more than the standard one, and you can also buy some extra features. It is a good thing to look at them because you would probably want to buy them. You should take your time and negotiate the price. They are easy. Like all cloud providers, they are able to discuss the price and if necessary, change the price."
"The licensing side of things with LogicMonitor, is quite simple. It is one license per device. Recently, you have additional licenses with things, like LM Cloud, which does confuse things a bit. Because it's very hard to estimate how many licenses you're going to need until you're monitoring it, so it's quite hard through that process to give a customer price to say, "This is how much this services will cost.""
"The pricing is quite reasonable, especially when compared to the broader market."
