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.

Pros

"Prometheus is a scalable and flexible tool that I can deploy on any cloud platform."
"The most valuable features of Prometheus are the many functions available. The functions are helpful for understanding the behavior of applications and infrastructure."
"I like its lightweight configuration functions."
"Prometheus gives us high availability automatically."
"The scalability of Prometheus is very good."
"Prometheus is an open-source product that helps mold and improve it per our requirements. It is a lightweight solution that gives you many different metrics you can use in your application. The product offers complete granularity of your infrastructure. It integrates seamlessly with other tools like Grafana, which offers dashboard visibility. Prometheus is an extensively used product. I haven't seen any organization that is not using it."
"The dashboard is very valuable."
"The most valuable features of Prometheus for metrics collection and monitoring are its stability, robustness, and rich set of features."
"The most valuable features include user time tracking and the ability to analyze application load times."
"The most valuable features include user time tracking and the ability to analyze application load times."
"The initial setup of Splunk Real User Monitoring (RUM) was easy."
 

Cons

"A slight alteration to the user interface should be made to increase efficiency and streamline the process. Currently, we are utilizing Prometheus to gather and compile metrics and then utilizing Grafana to display them in the form of a graph. However, I believe that Prometheus has the capability to handle both of these tasks on its own, with perhaps the addition of a supplementary plugin. By doing so, the need for utilizing two separate applications will be eliminated."
"The setup could be made easier for new users because it requires a bit of advance knowledge or experience."
"Prometheus can be initially difficult for users since it has its query language, PromQL. The minimalistic interface is complicated to understand. They need to improve their interface so that users who don't know PromQL can also use it. You can only leverage the tool when you know PromQL."
"The scalability must be improved."
"The simplicity of the query language could be improved. The current query language is not easy to work with."
"The solution's error handling part could be improved."
"The UI and GUI are areas of concern in the product."
"Its stability could be even better."
"It would be beneficial to have more enhanced features with capabilities to adapt more integrated applications. Improvements in dashboard configuration, customization, and artificial intelligence functionalities are desired."
"The initial setup of Splunk Real User Monitoring (RUM) was easy. The solution is deployed on-premises."
"There is room for improvement in customer support due to delays and standard feedback responses."
 

Pricing and Cost Advice

"We use the solution's open-source version."
"It is an open-source tool."
"The product is free."
"The solution is free of cost."
