So many Out of the box integrations which makes monitoring almost your entire tech stack is super fast easy and easy.

For example, earlier I was part of the search team and was managing 25+ large Elasticsearch clusters and Elasticsearch as a software has its own specialized metrics which we need to monitor and get alerted.

We didn't have to do anything with Datadog(DD) as Datadog already had a Out of the box integration with Elasticsearch and documentation for same can be easily found on google for ex: https://docs.datadoghq.com/integrations/elastic/?tab=host

This made our life super easy as we can just start monitoring large system without much configuration. Review collected by and hosted on G2.com.

Out of the box integrations are good but when you need to add more metrics which are not available, it requires a effort and sometime their documents can be confusing and outdated esp. with Out of the box integration where that software is changing rapidly.

Second it can be costly if you need to monitor large systems and is tight on the budget. Review collected by and hosted on G2.com.
