Highlights

Datadog and Prometheus are IT service monitoring tools designed to give businesses insight into the performance of their hardware and software stacks. Datadog is a single-pane-of-glass solution with monitoring, alerting, data analysis, and visualization capabilities. Prometheus is a free open-source tool focused solely on monitoring and alerting. On TrustRadius, Datadog is used primarily by mid-sized companies, while Prometheus is primarily used by large enterprises.

Features

Although both Datadog and Prometheus have similar core functionality, their user experience and implementation are significantly different.

Datadog is a professionally-supported product with plenty of visual analysis and quality-of-life features. Users on TrustRadius appreciate that it allows them to monitor performance, manage alerts, add and remove monitored resources, and analyze data from a single centralized application. Its data analysis tools in particular give customers multiple ways to view, manipulate, and understand the metrics generated by Datadog. The platform has a wealth of functionality available, and a wide array of officially-supported extensions add helpful features. A professional support team and strong user community help customers resolve any problems they may encounter.

Prometheus, on the other hand, is a free open-source tool that focuses exclusively on monitoring and alerting. As a standalone application, Prometheus has a simple initial setup. It stores all scraped metrics in a database that can be searched with a query language to retrieve and evaluate performance data. Prometheus is extremely customizable, with several community-supported integrations and the freedom to create and tweak alerting rules as needed.

Limitations

Datadog and Prometheus won’t be the right solution for every business, as they have significantly different user experiences. Make sure you consider the limitations of each platform before committing to one or the other. 

According to reviewers on TrustRadius, Datadog can be overwhelming for new users. Its large array of functionality can be useful, but it can also be intimidating for new users. Overall, the platform requires significant user training and customization. Even experienced users have reported difficulty navigating the platform. Some features and edge cases lack sufficient documentation, necessitating a customer support ticket or a request for help from the community. Although Datadog’s price point is reasonable when compared to licensed competitor software, customers still have to pay per host, per GB of log data, or per log event. For smaller organizations, Datadog may very well be overkill.

In comparison, Prometheus offers a classic open-source experience—for better or for worse. Users must be prepared to write code, create configuration files, and operate without a GUI. New users will also have to spend plenty of time learning how to use Prometheus. Since it is an open-source software with no professional support, users will need to rely on community documentation and support, which may be sparse or take time to get results from. Additionally, Prometheus relies on third-party applications for data visualization and analysis, requiring users to manually configure the dataflow from a monitored application to Prometheus, and then from Prometheus to other software. Finally, Prometheus has no built-in authentication or authorization features, relying on other tools to provide access security.

Pricing

Datadog offers several per-month pricing models designed to adapt to various operation scales and requirements. These models include pricing per host, per million log events, per function, per GB of analyzed log files, and per session. For more details on the available plans and pricing, refer to the Datadog pricing page.

Prometheus is open-source and can be downloaded for free.

Datadog

Datadog is a no-brainer for any environment that relies on multiple servers. Even for one server, it's so much better to use for monitoring and alert capability than anything else I remember looking at before we started using Datadog. Teams can even use it to track their progress of investigating an alert so multiple people aren't unknowingly looking into the same exact issue unnecessarily.

Prometheus

In an environment where there is just not one product that can monitor all aspects, Prometheus can step in. It can be used to monitor physical, virtual, containers, just about anything. With it being open source, the community comes together and has created several exporters to get data from almost anything imaginable.

Pros

Datadog

  • APIs, the ability to interact with the data we pull into data dog is key. We port the information over to Servicenow, so the ability to pull everything into DataDog, then Servicenow, is a key component of our success here at Wayfair.
  • Simple Interface - clean, useful, effective. Allows users to use DataDog for one reason, get work done.
  • Lightweight agent on hosts

Prometheus

  • Inbuilt database.
  • Amazing visualization.

Cons

Datadog

  • User interface could be improved in some areas, looking for host information and the agent install link takes a bit of time.
  • Configuration of the agent is generally done via a config file which is a pro and a con. It would be nice to have some UI to configure various agent options.
  • Billing isn't entirely straightforward, they could use more reports to figure out the source of your monthly costs.

Prometheus

  • PromQL can be difficult to learn at first.

The user interface is quite intuitive with the exception of the network map. As a deployer of software, it is trivial to setup.

The support team usually gets it right. We did have a rather complicate issue setting up monitoring on a domain controller. However, they are usually responsive and helpful over chat. The downside would be I don’t think they have any phone support. If that is important to you this might not be a good fit.

Alternatives Considered

Datadog

We are still trying other products, but people still like Datadog. After setting up a dashboard, it's great for monitoring instances on Datadog. Also, the DevOps team had a good time setting up Datadog. It means Datadog was way easier to set up compared to those others.

Prometheus

We evaluated Datadog and New Relic but cost-wise, these 2 are very expensive. Prometheus does require more leg work to match the feature sets but other than time, the cost is free. Pairing with Grafana, Prometheus can pretty much match features with the big players and still remain free.

Return on Investment

Datadog

  • One of our critical production databases went down a couple of weeks back. Just because we had the Datadog monitoring enabled for that database, Datadog sent the alerts to PagerDuty and we were instantly notified via pager and email alert. We could act right away and bring up the database within a few mins.
  • Ability to create custom screenboards have allowed us to track the critical and warning alerts in front of our eyes all the time
Rajeshh Raghavan | TrustRadius Reviewer

Prometheus

  • It's free, but overall positive.
  • Just view the dashboard in the morning and you know everything about your system.
