Summary
In a traditional computing scenario where hosts are involved, infrastructure monitoring is the core of monitoring. Hosts include both bare-metal and virtual machines. With the increased use of microservices to deploy applications, the container has become an important element in building infrastructure. Datadog provides features that support both host- and container-level monitoring. The Datadog feature of aggregating processes from the hosts makes comparing runtime environments at the host level easy. Though no infrastructure is involved, Datadog can be used to monitor serverless computing resources such as AWS Lambda functions. In this chapter, you learned how various components of the infrastructure that run a software application system are monitored using Datadog. These infrastructure components could be in traditional data centers or public clouds, and they could be virtual machines or containers.
Though useful metrics can be published to Datadog or generated by it...
