Setting up monitors
In a generic monitoring system, a monitor is usually tied to metrics or events, and Datadog covers these and much more. There are multiple monitor types based on the data sources defined in Datadog. Some of the most important ones include the following:
- Metric: As mentioned at the beginning of this chapter, metrics are the most common type of information used to build monitors. A metric type monitor is based on the user-defined thresholds set for the metric value.
- Event: This monitors the system events tracked by Datadog.
- Host: This checks whether the Datadog agent on the host reports into the Datadog Software as a Service (SaaS) backend.
- Live process: This monitors whether a set of processes at the operating system level are running on one or a group of hosts.
- Process check: This monitors whether a process tracked by Datadog is running on one or a group of hosts.
- Network: These monitors check on the status of the TCP/HTTP endpoints. ...
