Pros
"The solution is useful to collect huge metrics.""The solution helps us to scale our products and services, and it helps me by gathering those metrics.""The most valuable features of Prometheus for metrics collection and monitoring are its stability, robustness, and rich set of features.""The product has an easy-to-understand interface.""It is highly valuable as it serves as the foundation for our infrastructure monitoring tools.""The solution offers an easy way to install and scratch values.""The good thing is it integrates well with the Grafana dashboard. It comes with a UI where you see everything as a graph.""It is a stable solution...Based on the feedback I have received from my colleagues in our company's IT department, the setup phase of the solution is relatively easy."

"Splunk's advantage is its search capability. Its search is notably faster. With Splunk, I can search easily on keywords. That is great.""It has reduced the time to resolution, time to investigate, and time to troubleshoot for debugging issues.""Splunk Enterprise Security offers two valuable features: the Common Information Model and arrangement modules.""I have also been able to take advantage of some of the more complex statistical capabilities when analyzing logs.""We did not encounter any issues with scalability. It is almost seamless to add new index (storage) or search (used to analyze the data) nodes to the cluster.""Our clients are easily able to modify and evolve their implementations.""Splunk incorporates a lot of elements that help to reduce security risks. For it to reach certain compliance, we need to have some security insight. Splunk is a very good SIEM, it’s a top solution, but the best feature is its cost of visibility. We have all the most important features to detect vulnerabilities or risks.""It helped us consolidate all our solutions into an easy tool to use for various employees."

Cons
"Its documentation could be clearer to understand.""The scalability must be improved.""Its stability could be even better.""The simplicity of the query language could be improved. The current query language is not easy to work with.""The solution has shortcomings regarding security monitoring-oriented features to support custom use cases, like out-of-the-box test scenarios and threat-related use cases of its users.""There isn’t much clarity regarding the issues that happen at the server end. It is a push model and from the client’s point of view, it needs to look better and solve remote issues.""One potential area for improvement would be fixing the occasional glitches and bugs.""The product must improve its documentation."

More Prometheus Cons →

"We would like more integrations with other cloud products, not just AWS, e.g., Azure.""A lot of people are averse to using new tools so if they make it even more user-friendly than it already is, I think that could go a long way.""There can be a bit of complexity around some fields during the initial setup.""The configuration could be better.""There is improvement needed when importing from some types of data sources.""I find that the learning curve for Splunk is relatively lengthy.""The UI can be improved. Dashboards and reports can be better in terms of graphics.""We'd like Splunk to reduce false positives."
