Sentiment score
6.6
Nagios XI enhances efficiency and time management but concerns about increased costs affect ROI perception across organizations.
The return is more of value and savings in preventing costly downtime, making the savings of about $60,000 which we would have lost without LogicMonitor, and in IT staff efficiency, we save approximately 15 hours a week.

Scalability Issues

Sentiment score
7.7
LogicMonitor efficiently scales with growth, offering cloud-based expansion, role-based access, and automation for diverse business needs.
Sentiment score
7.1
Nagios XI is scalable for small to medium environments but faces challenges in large infrastructures and cloud adaptability.
They are not licensed, so you could deploy one collector or 1,000 collectors for the same cost.
Sr. Systems Engineer at a financial services firm with 201-500 employees
LogicMonitor's scalability absolutely meets our organization's growth needs.
Observability Engineer at Universal Music Group
LogicMonitor is pretty good at scaling things when it comes to monitoring AWS infrastructure because I can see that it scales very well for us.
Site Reliability Engineer at a comms service provider with 501-1,000 employees
If the user interface isn’t presenting data well, it becomes difficult to manage when scaling.

Stability Issues

Sentiment score
8.2
LogicMonitor's stability, reliable alerts, and minimal maintenance ensure high user satisfaction and allow focus on business systems.
Sentiment score
7.3
Nagios XI is stable, but large deployments may experience performance issues, database problems, and minor network dependencies.

It is very stable.
Network and Security Engineer at a educational organization with 1,001-5,000 employees
 

Room For Improvement

LogicMonitor users want better visualization, streamlined alerts, automation, enhanced monitoring, role-based permissions, and more appealing pricing options.
Nagios XI's interface is outdated, lacks scalability, needs better cloud integration, APIs, automation, and improved documentation.
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.
Site Reliability Engineer at a comms service provider with 501-1,000 employees
I wish the user interface would be customizable to allow users to create personal context-specific workspaces to hide irrelevant data, rather than trying to have a one-size-fits-all interface.
IT Infrastructure Engineer at Ethical Trade SErvices Africa
The container monitoring seems to be really behind compared to some bespoke cloud-native monitoring solutions that are designed around Kubernetes, containers, and ephemeral environments.
Sr. Systems Engineer at a financial services firm with 201-500 employees
Many tools have poor user interfaces, making them hard to manage and navigate.
Network and Security Engineer at a educational organization with 1,001-5,000 employees
The GUI could be improved. It's a bit too basic.

Setup Cost

LogicMonitor offers competitive pricing and value, though clouds licensing can be challenging for larger environments or small businesses.
Nagios XI provides cost-efficient enterprise-level monitoring with reasonable pricing, appreciated for its features and open-source options.
For small businesses that want to utilize LogicMonitor and are just starting out with limited customers, a pricing model targeted to this segment would be beneficial, perhaps at three or two dollars per device per month.
Network Security Engineer at a consultancy with 10,001+ employees
I experienced no issues with pricing, setup cost, and licensing; it was very transparent, and the licensing model is very clear and easy to understand.

We are using the free, open-source version.

The pricing for the Nagios XI product is good and better than other solutions.

Valuable Features

LogicMonitor offers customizable dashboards, real-time visualization, and advanced alerting for proactive network management and efficient issue resolution.
Nagios XI provides customizable, flexible, and scalable IT infrastructure monitoring with real-time alerts and extensive plugin support.
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.
IT Infrastructure Engineer at Ethical Trade SErvices Africa
Our SLAs and SLOs were averaging about 10 to 15 failed SLAs and SLOs that were over the time allotted to get those resolved, and those are now down to about two to three per week.
Observability Engineer at Universal Music Group
When talking about the statistics, it has helped us reduce downtime to about 40 to 50% because without LogicMonitor, we used to know about the downtime only when the application was actually down.
Site Reliability Engineer at a comms service provider with 501-1,000 employees
Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.
Network and Security Engineer at a educational organization with 1,001-5,000 employees
The alerting system is very effective.

Anshuman Thakur - PeerSpot reviewer
Site Reliability Engineer at a comms service provider with 501-1,000 employees
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.

Simplifies setup and requires user interface enhancement
Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried. Typically, setting up a monitoring system on Linux involves cloning files from GitHub, building it, and installing many dependencies, but with Nagios XI, it wasn't like that. Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
I have researched a quite a few network monitoring tools which can be used for various monitoring purposes of not only the servers, but the intermediate routers as well. There are majorly three types of these softwares. Ones which are completely open-source, you can do almost anything you want…
