I like Datadog because it is so easy use, I can easily connect to public clouds, and I have a view of observability. In my opinion it's the best tool in the market.
I like the interface so much. The interface and the integrations make it so easy to connect to the cloud or to the on-premise environment. It has so many monitors for alerting. I like all the versions and especially the APM model, on which I did a lot more testing with my applications. I have made applications for testing the tool that is in the resource. The APM is the goal for me in the Datadog.
In terms of what could be improved, Datadog does not have the feature where you can monitor external websites or check the SSL secure for websites.
I have been using Datadog for the last 14 days.
In terms of stability, I don't have any problem with its stability or the website data. They have a solid infrastructure. I don't have any problems with that.
It was simple to configure and to set up this tool.
I have less experience with Zabbix than I have with Datadog, but I don't see Zabbix as a great tool for cloud specific monitoring because I cannot connect so easily to public clouds to gain all the information that I can in Datadog, which I can easily set up.
I have used Zabbix for 20 days for my personal tests and I really don't like it.
There is something that I liked with Zabbix, though. Zabbix is better for monitoring virtual machines. That's a feature that I liked. But everything else is awful. I can't have dashboards. I do not have integrations with some ITSM systems, like Jira or OTRS. It's awful because I need to have those integrations.
I would rate Zabbix a nine from one to ten for on premises environments. For cloud platforms, I rate this tool as a five, because of the complexity required to integrate it in other platforms.
On a scale of one to ten, I would rate Datadog a nine, just because of the missing feature of checking websites.
