Cloud Solution Architect at Cloudzant
 

Customer Service

Sentiment score
6.1
Azure Monitor's customer service is praised for responsiveness, especially with premium support, but can improve on general knowledge and speed.
Sentiment score
6.5
Nagios XI support is mixed; praised for responsiveness but criticized for high cost, complex licensing, and delayed responses.
However, the second-line support is good.
Snr. Infrastructure Architect (Data Centre) at LogicEra
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.
Software Engineer (DevOps/ SRE) at Sensys LLC
I would rate the support for Azure Monitor as a seven.
Cloud Solution Architect at Cloudzant
 

Scalability Issues

Sentiment score
7.8
Azure Monitor provides scalable solutions for businesses, supports auto-scaling, integrates with tools, but requires careful cost management.
Sentiment score
7.1
Nagios XI is scalable for small to medium environments but faces challenges in large infrastructures and cloud adaptability.
With APM, you can go heavy or you can go light. It just depends on what you want, what your use case is, and how reactive you want to be to system load or resilient to failure.
Consultant at a outsourcing company with 201-500 employees
Azure Monitor is very scalable; there are no issues with scalability for different kinds of businesses.
Cloud Solution Architect at Cloudzant
If the user interface isn’t presenting data well, it becomes difficult to manage when scaling.
Network and Security Engineer at a educational organization with 1,001-5,000 employees
 

Stability Issues

Sentiment score
8.3
Azure Monitor is highly stable and reliable, though less agile, with high user ratings and potential cost concerns.
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.
Snr. Infrastructure Architect (Data Centre) at LogicEra
It is very stable.
Network and Security Engineer at a educational organization with 1,001-5,000 employees
 

Room For Improvement

Azure Monitor struggles with user-friendliness, integration, complexity, multi-cloud support, proactive monitoring, and requires enhanced usability and cost transparency.
Nagios XI's interface is outdated, lacks scalability, needs better cloud integration, APIs, automation, and improved documentation.
My perspective is more based on an Application Insights agent running on a service or an app service and sending the telemetry via the agent, and also doing the filtering of telemetry at the agent level so you are not having a ton of telemetry.
Consultant at a outsourcing company with 201-500 employees
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.
Software Engineer (DevOps/ SRE) at Sensys LLC
The challenges with Azure Monitor are that it's initially complex to set up because you need multiple components.
Cloud Solution Architect at Cloudzant
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.
Site Duty Manager at Assw
 

Setup Cost

Azure Monitor offers cost-effective variable pricing, but careful management is essential to avoid high expenses for enterprise users.
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.
Snr. Infrastructure Architect (Data Centre) at LogicEra
We are using the free, open-source version.
Site Duty Manager at Assw
The pricing for the Nagios XI product is good and better than other solutions.
Network and Security Engineer at a educational organization with 1,001-5,000 employees
 

Valuable Features

Azure Monitor provides comprehensive real-time monitoring, alerting, and analytics, enhancing security and scalability for seamless infrastructure management.
Nagios XI provides customizable, flexible, and scalable IT infrastructure monitoring with real-time alerts and extensive plugin support.
The alerting features definitely help in reducing operational downtime for my customers by allowing us to get notifications in advance and take active actions.
Cloud Solution Architect at Cloudzant
I also appreciate the ability to measure feature activity, see what types of devices they are on, follow specific use cases, and measure the amount of traffic going to a particular application.
Consultant at a outsourcing company with 201-500 employees
Resource monitoring is essential.
Snr. Infrastructure Architect (Data Centre) at LogicEra
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.

Telemetry insights have improved how I track user behavior and application performance daily
I feel Azure Monitor does a fair job. I do feel it is not a streaming service in my opinion. There are advantages to having stream messaging and logging on that level. But for what it is, I feel it does well. My perspective is more based on an Application Insights agent running on a service or an app service and sending the telemetry via the agent, and also doing the filtering of telemetry at the agent level so you are not having a ton of telemetry. I believe Azure Monitor does pretty much the same thing. I have also used tools such as New Relic, and New Relic is a much more robust tool, but that is a different product and you are going to pay for that. It is a different offering altogether. The subscription that we had at the time allowed for a couple gigabytes of telemetry during the month, and I believe that telemetry only lives for about two months. You have to experiment with it to see how much you want to pay. I was not really involved in the pricing. It was more along the lines of we were running up against our limits in terms of the amount of free telemetry or telemetry that we get with our subscription, and so we either needed to scale back or turn specific telemetry types off or do some more sampling. It is nice that those capabilities are there so that you can reduce the amount of telemetry. I cannot really speak to pricing but I do believe that it is somewhat reasonable for Azure Monitor. New Relic is pretty expensive, I believe.

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…
