Review summaries and opinions

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

ROI

Sentiment score

Azure Monitor offers cost-effectiveness and proactive visibility, with pay-as-you-go flexibility and potential savings despite mixed ROI feedback.
Sentiment score
8.5
Prometheus Group is free and cost-effective, offering substantial savings and efficient monitoring compared to AWS native services.
Using open-source Prometheus saves me money compared to AWS native services.
 

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
4.0
Prometheus Group support relies on comprehensive documentation and active community forums, praised for their helpfulness and accessibility.
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.
Prometheus does not offer traditional technical support.
 

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
6.9
Prometheus Group efficiently scales from small to large enterprises, supporting extensive user bases with minimal maintenance required.
Prometheus is scalable, with a rating of ten out of ten.
 

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
8.9
Prometheus Group is praised for stability and frequent updates, despite occasional performance issues tied to infrastructure.
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.
Deploying it on multiple instances or using Kubernetes for automatic management has enhanced its stability.
 

Room For Improvement

Azure Monitor requires better integration, user experience, automation, alerting, support, cost clarity, and improved interface and performance monitoring.
Prometheus Group's setup and query language are challenging; improvements needed in UI, documentation, integrations, security, error handling, and pricing.
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.
 

Setup Cost

Azure Monitor's flexible pricing is generally competitive, but costs can rise due to storage and integration needs.
Prometheus Group is cost-effective due to its open-source nature, preferred over more expensive solutions like New Relic or Datadog.
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.
Prometheus is cost-effective for me as it is free.
 

Valuable Features

Azure Monitor provides seamless integration, robust security, dynamic alerting, and efficient reporting, enhancing user satisfaction with scalability and cost-effectiveness.
Prometheus Group offers robust API integrations, customizable dashboards, scalability, and adaptability, ensuring efficient monitoring across diverse environments.
The ease of access in Azure is significant because it's native to the platform and easy to integrate.
Resource monitoring is essential.
It allows me to save money by avoiding costs associated with AWS native services like CloudWatch or Amazon Prometheus.

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.

Free to use and provides valuable monitoring capabilities
Prometheus is a scalable and flexible tool that I can deploy on any cloud platform. It is free to use and provides valuable monitoring capabilities. It allows me to save money by avoiding costs associated with AWS native services like CloudWatch or Amazon Prometheus. The ability to deploy on any cloud platform or environment, including Kubernetes, is a major advantage.
