Prometheus Reviews in March 2025: User Ratings, Pros & Cons

Prometheus - The Alerting Way

What do you like best? The Best thing I liked about Prometheus is that It comes with it's own Prom Query Language. Once we learn Prom Query Language, we can write any query to define alerting rules. Also it comes with many aggregate functions which can be used to filter and apply mathematical calculations on the alerts. It comes with wide variety of alerting metrics. Example for Virtual machines and also for Kubernetes Clusters. What do you dislike? There is very minimum things to ...

Blazing fast, reliable & free TSDB

What do you like best? It works on the pull model. This helps the TSDB to decide at what rate it wants to pull the data from the clients. What do you dislike? It only supports HTTP APIs to pull the data into the DB. I wish it could add more methods like S3 pull etc. Recommendations to others considering the product: Its reliable and free to use. There is great community support. Fully configurable to pull data from various sources via API calls and rate at which the data is ...

Amazing open source tool for monitoring, very customizable

What do you like best? Approach and philosophy, auto discovery. What do you dislike? Not very easy to start with the product. Learning curve. Recommendations to others considering the product: Try it ! Best monitoring solution in 2020. What problems are you solving with the product? What benefits have you realized? Auto discovery for auto scaled machine in AWS for example.

The monitoring way of the future

What do you like best? The entire product stack is open source. Far more flexible than traditional monitoring solutions like Nagios. A wide variety of Prometheus metric exporters already in the community, and many open source products are natively incorporating Prometheus exporters. What do you dislike? Prometheus developers and export developers have punted on security by leaving implementation up to other products. I get that they want to focus on the core of the product, but ...

What do you like best? It is very simple to use and has no external dependencies. It has a powerful query language to retrieve and evaluate metrics. What do you dislike? Using it little bit difficult. Routing from different ports is difficult.

Using for database for storing run-time data.

Prometheues from dev to prod

What do you like best? i like that its really light weighted and is compatible to collect data from many exporters What do you dislike? i dont like the alert manager part , its really complex and we find difficulties to configure using equations and promQL stuff What problems are you solving with the product? What benefits have you realized? gathering multiple metrics from different apps/infra and store them in a time series db

Extremely good opensoucre monitoring tool

What do you like best? Detailed monitoring of any metrics can be measured. What do you dislike? The learning curve is bit steep and also there is no unique identifier for alerts generated by the Alertmanager. Recommendations to others considering the product: Prometheus is an essential tool for companies operating in the cloud and it's free, however the learning curve is bit steep and it might need some time to configure the system properly. What problems are you solving with ...

A Deep Well of Metrics

What do you like best? The depth and granularity of the metrics made available by Prometheus are better than any monitoring tool I have used to date. The configuration documentation is long but covers everything in great detail. There was not an issue creating the service accounts, setting user permissions or building our first configuration files. What do you dislike? This is not an easy setup. It's not insurmountable and the documentation is good but the configurations of user ...

Decent tool for the cloud immutable infrastructure monitoring and alerting

What do you like best? Easy redeployable, very fast database (even the giant queries are running super-fast), concept of the services monitoring instead of the instances monitoring. Really adequate queries syntax, simple alerting, in-house integration with the Grafana. It's already has the exporters for more-or-less whatever technology you are using. Even if there are no exporters for your specific system or needs, you are always able to write your own one on the whatever language you ...

Very flexible monitoring system that works well with K8s

What do you like best? Prometheus is the industry standard for monitoring. There are a lot of plugins and works well with other hybrid solutions like Google Stackdriver What do you dislike? The setup process / learning curve is pretty steep. What problems are you solving with the product? What benefits have you realized? We were building a monitoring system for our kubernetes clusters. It is very flexible and can pull data out in various ways.
