ROI

Sentiment score
7.0
Azure Monitor offers cost-effectiveness and proactive visibility, with pay-as-you-go flexibility and potential savings despite mixed ROI feedback.
Sentiment score
6.6
Nagios XI enhances efficiency and time management but concerns about increased costs affect ROI perception across organizations.
 

Customer Service

Sentiment score
6.1
Azure Monitor support is generally positive, with high-priority users obtaining quicker responses, while others report variable experiences.
Sentiment score
6.5
Nagios XI support is mixed; praised for responsiveness but criticized for high cost, complex licensing, and delayed responses.
Users end up getting no resolution from their team because they're outsourced vendors, and they don't have deeper expertise over any of the products they are referring to.
However, the second-line support is good.
 

Scalability Issues

Sentiment score
7.7
Azure Monitor efficiently scales across industries, integrating well with services, and reliably supports growing infrastructure and application needs.
Sentiment score
7.1
Nagios XI is scalable for small to medium environments but faces challenges in large infrastructures and cloud adaptability.
If the user interface isn’t presenting data well, it becomes difficult to manage when scaling.
 

Stability Issues

Sentiment score
8.3
Azure Monitor is stable and reliable with high ratings, but could improve in alerting compared to competitors.
Sentiment score
7.3
Nagios XI is stable, but large deployments may experience performance issues, database problems, and minor network dependencies.
Azure Monitor is working fine, yet I face a costing issue as if there are a lot of logs collected in the workspace or in the center, it becomes very costly.
It is very stable.
 

Room For Improvement

Azure Monitor requires better integration, user experience, automation, alerting, support, cost clarity, and improved interface and performance monitoring.
Nagios XI's interface is outdated, lacks scalability, needs better cloud integration, APIs, automation, and improved documentation.
The cost skyrockets once you start using it, and there are complaints that the actual cost of the Kubernetes cluster was less than the cost they were incurring for Azure Monitor.
If Azure Monitor can independently add one gigabyte, two gigabytes, or five gigabytes at least to log storage, I can fix the logs without syncing with Log Analytics Workspace and Sentinel.
Many tools have poor user interfaces, making them hard to manage and navigate.
The GUI could be improved. It's a bit too basic.
 

Setup Cost

Azure Monitor's flexible pricing is generally competitive, but costs can rise due to storage and integration needs.
Nagios XI provides cost-efficient enterprise-level monitoring with reasonable pricing, appreciated for its features and open-source options.
When I export logs into the application, workspace, log analytic workspace, and into Sentinel to read reports, I need to add storage, which increases the cost.
We are using the free, open-source version.
The pricing for the Nagios XI product is good and better than other solutions.
 

Valuable Features

Azure Monitor provides seamless integration, robust security, dynamic alerting, and efficient reporting, enhancing user satisfaction with scalability and cost-effectiveness.
Nagios XI provides customizable, flexible, and scalable IT infrastructure monitoring with real-time alerts and extensive plugin support.
The ease of access in Azure is significant because it's native to the platform and easy to integrate.
Resource monitoring is essential.
Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.
The alerting system is very effective.

Muhammad Usman Khawar - PeerSpot reviewer
Native integration simplifies monitoring but documentation and cost improvements are needed
The ease of access in Azure is significant since it's native to the platform and easy to integrate. It has no maintenance overhead, and users don't have to navigate to another portal to get their desired result. It's the handiness that it has, rather than the features. The interpretation from the logs and injection requires custom runbooks. While it's complex, many services provide native insights and workbooks. It does the basic job quite efficiently. They added new kinds of metrics with more integrations to send out metrics. They have even added support for third-party tools that can be integrated. Azure Monitor is working on improvements and becoming more mature. Azure Monitor is stable and scalable. Azure Monitor is evolving with new workbooks and dashboards.
Amir  Said - PeerSpot reviewer
Effective alerting enhances network monitoring experience with an easy setup
We love Nagios XI due to the fact that JPS Web is very useful. JPS monitors the modem and performs switching, monitoring the computer, and performing switching. We implement some applications and traffic monitoring. The alerting system is very effective. For instance, if we have an alarm on some RAM storage if the traffic is cut or dropped.
