"Best monitoring tool out there"
5/5
What do you like best about Prometheus?

You can define your own metrics for your application that want to monitor. Paired up with Grafana makes it a really powerful tool. It's Alert manager is a cherry on top. Review collected by and hosted on G2.com.

What do you dislike about Prometheus?

Just the integrations are a bit tough to crack on windows. If it can be made for windows then it will become the best monitoring tool out there. On Linux it works pretty fine. Review collected by and hosted on G2.com.

What do you dislike about Prometheus?

Documention on performance parameter is not so good and lack knowledge on setting correct resources for production level traffic. We have faced issues related to dimensioning on production site because multiple queries on multiple window cause application to consume too much memory. Review collected by and hosted on G2.com.

"This is a powerful monitoring tool"
3/5
What do you like best about Prometheus?

A good monitoring tool, I have used it for the past 1 year and I have never seen any kind of problem till now. almost covered all the useful metrics that need to be monitored. at first, it is complex to implement but once these problems are solved it can be the best monitoring solution for your environment, In addition to being able to use it as a service, its requirements are not very high, this helps to keep a low budget in monitoring storage. Review collected by and hosted on G2.com.

What do you dislike about Prometheus?

You may need more than one server or service in addition to addons to complement the monitoring needs, for those new to the platform it is complicated, its different modules can confuse in its implementation Review collected by and hosted on G2.com.

"There no other choice"
4/5
What do you like best about Prometheus?

The whole design of Prometheus where goes ahead and scrapes data. Push gateways for the cases it is not possible. The easy way one can publish metrics if one is serious about consuming them. Review collected by and hosted on G2.com.

What do you dislike about Prometheus?

PromQL. There are not enough words to describe the horrificness of the language. This looks like a weird hack because someone liked to express themselves with relational algebra and not knowing enough Prolog to use it as a query language instead. Review collected by and hosted on G2.com.

Best monitoring tool I have ever seen, am using it for last 4 years never seen any kind of issues so far. Almost covered all the useful metrics which needs to be monitored.

There is no major concerns as such but I have seen few metrics are missing even in the latest versions also, for example the latency for datastores metrics for VMware is missing. Review collected by and hosted on G2.com.

Metric-based and best cloud Native tool support, Best monitoring tool which I am using for months and continuing. It provide execellent insights from a variety of matrics. Review collected by and hosted on G2.com.

What do you dislike about Prometheus?

PromQL is something if you don't know you will face issues. It you are at initial stage you need to have good hands-on to get the things done. But before that thing can be frustrating. Review collected by and hosted on G2.com.
