"We can manage the entire system across the network and troubleshoot the pain points."
"Datadog provides tracing and logging, whereas Dynatrace focuses on tracing, and Splunk is more of a logging tool. Datadog's advantage is that we don't need two tools."
"For us to have visibility into our app stack and the hardware we run has been highly beneficial."
"By moving to Datadog, we did not need to manage our own monitoring infrastructure anymore."
"Its logs are most valuable."
"The interface and the integrations make it so easy to connect to the cloud or to the on-premise environment."
"The many dozens of integrations that the solution brings out of the box are excellent."
"Datadog agents act as an integration to different services, providing easy access and management."
"APM is great and has provided low-effort out-of-the-box observability for various services."
"The notifications are definitely one of the most valuable features of Nagios Core. We know what to look for and what to expect when things are down."
"Provides timely notifications."
"Alert calls occur anytime a service goes down or a matrix is difficult and that helps us to quickly restore service and transfer work."
"The most valuable feature is the performance parameters of the system."
"The application performance monitoring feature is valuable."
"Other products are good but from the configuration point of view Nagios is really very lightweight. The price is really good in my opinion. Another important thing is that my Nagios engine still works with Dual core 8GB ram for the last 10 years."
"We use the product to monitor server applications."
"Key features include the GUI interface, its notification capabilities, and the real-time reporting."
"The Wi-Fi side needs improvement."
"I'm not sure if Datadog can monitor K8s deployments in real-time. For instance, being able to see a deployment step by step visually. This would be helpful if there were any incidents during the deployment."
"Some of the interface is still confusing to use."
"We need more advanced querying against logs."
"The solution should provide alerts for cloud outages."
"We would like to see some versioning system for the Synthetic Tests so that we could have a backup of our tests since they are time-consuming to make and very easy to damage in a moment of error."
"Datadog isn't as mature as some of the established players like Dynatrace or Splunk. It's a new product, so they are constantly releasing new features, and I don't have much to complain about."
"Once agents are connected to the Datadog portal, we should be able to upgrade them quickly."
"Datadog could always lower the price!"
"The UI is a little outdated and graphics could be displayed in a better way."
"Nagios Core does not have a graphic display."
"The core version is no match for the XI version."
"I believe Nagios Core will need to provide an option for big data platforms in the future."
"I would like to see more training videos."
"It would be nice if the company offered a sales or contract manager that was dedicated to our company so that we would have some sort of link to Nagios, and if we had issues or questions, we'd be able to contact them directly."
"Would benefit from aggregations if a particular server goes down."
"Nagios Core can improve the graphical interface, it would make things a little easier."
