Datadog

Datadog is an observability platform for cloud-scale applications. Integrating your Render services and databases with Datadog can provide your applications with fine-tuned metrics, monitoring, and automated alerting.

Getting Started

Sign up for a Datadog account, if you don’t already have one. Then create or retrieve an API key from your Datadog organization settings page.

Setting up Postgres monitoring

While creating a Postgres database, enter your Datadog API key in the respective field, as shown below. Adding an API key will enable a Datadog agent to run alongside your Postgres instance and report metrics to your Datadog account.

The metrics reported by the Datadog agent are all native to the Datadog platform, so you will not be charged any fees for custom metrics.

Attaching a Datadog API key is only supported for new databases. If you would like to enable this for an existing database, please reach out to support@render.com.

Available metrics

While the Render Dashboard metrics provide you with the core Postgres metrics, using Datadog can provide more detailed metrics about the Postgres instance host environment. You can also use Datadog as a centralized location for dashboards and automated alerts.

The following Datadog integrations are fully supported, and you can view all the metrics listed in the documentation linked below.

• Postgres - metrics related to your PostgreSQL instance
• Disk - metrics related to disk usage and IO for your Postgres volume
• Network - metrics related to TCP/IP network stats of instance

In addition to the above integrations, the following metrics are also reported:

Metric	Description
system.cpu.num_cores	The number of CPUs, as chosen by your database plan
system.cpu.system	The percentage of time the CPU spent running the kernel
system.cpu.user	The percentage of time the CPU spent running user space processes
system.mem.free	The amount of free RAM
system.mem.total	The total amount of physical RAM, as chosen by your database plan
system.mem.used	The amount of RAM in use

Viewing the metrics

Within Datadog, you can see the metrics on any dashboard or metrics explorer page. You will be able to filter metrics by the database-id tag equal to your Render Postgres database ID. The screenshot below is an example of some metrics you can view.

Setting up Log Streams

You can use Datadog as a logging provider for Render Log Streams, which will allow you to view and manage logs from any Render service or databases directly from your Datadog dashboard.

To set this up, follow the instructions from the log stream docs, using your Datadog API key and the endpoint that corresponds to your Datadog site:

Datadog Site	Endpoint
US	intake.logs.datadoghq.com:10516
EU	tcp-intake.logs.datadoghq.eu:443
