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

"We have had a fantastic experience so far; it is a fantastic product, it is definitely worth looking at, and it has definitely delivered on our requirements."
"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 helps us prevent potential downtime. It's pretty good. It generates low-level warnings that aren't necessarily preemptive but can still alert us to issues we should investigate. These warnings allow us to correlate data and identify areas where we should take action, even if the issues aren't critical."
"From the time that I started using it, I haven't had any issues with the software at all."
"LogicMonitor is very reliable compared to many other monitoring tools I have used, as each individual BGP session, IPsec tunnel, and interface is captured accurately and the logs are highly reliable."
"LogicMonitor has positively impacted our organization by allowing us to implement it for 1,200 clients or 1,200 endpoints within three months, which went very well."
"I really appreciate the reporting function because it allows me to create dashboards that will be emailed to me during the morning so that I have a complete overview of my client's health, within a specific time frame."
"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 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."
 

Cons

"The only functional area I can think of that has room for improvement would be the dashboards. They could use a refresh. It would be nice if there were more widgets and more types of widgets."
"One drawback of LogicMonitor is its licensing model, which requires an additional license for each module. For example, if you need to use Azure monitoring, you'll need an additional license on top of the base license."
"It needs better access for customizing and adding monitoring from the repository. That would be helpful. It seems like you have to search through the forums to figure out what specific pieces you need to get in for specific monitoring, if it's a nonstandard piece of equipment or process. You have to hunt and find certain elements to get them in place. If they could make it a bit easier rather having to find the right six-digit code to put in so it implements, that would be helpful."
"In terms of improvement, I suggest that the pricing could be on the higher side for smaller organizations, advanced customization has a learning curve, and alert tuning may require initial optimization to avoid too many alerts."
"The process of upgrading some of the collectors has been a little bit confusing. I need to understand that better."
"LogicMonitor should always improve AI because we are always striving for real intelligence."
"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."
"Additionally, it times out after every couple of minutes, perhaps 20 or 30 minutes."
"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."
"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."
"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."
 

Pricing and Cost Advice

"I know we are saving at least several hundred thousand dollars in that we're not buying Cisco Prime."
"The features were very valuable to us because we could consolidate them into one platform and have a good user experience with the platform, our accounts, and the support team. That was the key driver for us. That was what we were looking for. We looked for a comprehensive solution that could provide advanced features all in one platform, and LogicMonitor was the solution that we chose. It definitely has a premium price. However, you are getting what you pay for in a very effective way. That was important in our decision-making.The features were very valuable to us because we could consolidate them into one platform and have a good user experience with the platform, our accounts, and the support team.

However, you are getting what you pay for in a very effective way. That was important in our decision-making."
"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."
"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."
"The pricing can be a little aggressive. Right now, it's a bit much for smaller organizations to adopt it. But comparatively, it also provides good features."
"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."
"In terms of pricing, I would rate LogicMonitor four out of five."
"As a managed service provider, we have the highest level of licensing that they offer, so we don't have any extra fees. I believe there are some add-ons for some of the lower tiers of LogicMonitor service, but that's not something that we use with our agreement."
"The pricing is quite reasonable, especially when compared to the broader market."
