Overview

All Agent traffic is sent over SSL. The destination is dependent on the Datadog service and site. To see destinations based on your Datadog site, click the DATADOG SITE selector on the right.

Installation

Add the following domains to your inclusion list to allow for Agent installation:

• install.datadoghq.com
• yum.datadoghq.com
• keys.datadoghq.com
• apt.datadoghq.com

All other Agent data

<VERSION>-app.agent.
For example, Agent v7.31.0 reports to 7-31-0-app.agent.. You must add *.agent. to your inclusion list in your firewall(s).
Since v6.1.0, the Agent also queries Datadog’s API to provide non-critical functionality (For example, display validity of configured API key):
Agent v7.18.0 or 6.18.0 and later: api.
Agent < v7.18.0 or 6.18.0: app.

Agent flare

<VERSION>-flare.agent.
For example, Agent v7.31.0 sends flare data to 7-31-0-flare.agent.. You must add *.agent. to your inclusion list in your firewall(s).

Static IP addresses

All of these domains are CNAME records pointing to a set of static IP addresses. These addresses can be found at https://ip-ranges..

The information is structured as JSON following this schema:

{
    "version": 1,                          // <-- incremented every time this information is changed
    "modified": "YYYY-MM-DD-HH-MM-SS",     // <-- timestamp of the last modification
    "agents": {                            // <-- the IPs used by the Agent to submit metrics to Datadog
        "prefixes_ipv4": [                 // <-- list of IPv4 CIDR blocks
            "a.b.c.d/x",
            ...
        ],
        "prefixes_ipv6": [                 // <-- list of IPv6 CIDR blocks
            ...
        ]
    },
    "api": {...},                          // <-- the IPs used by the Agent for non-critical functionality (querying information from API)
    "apm": {...},                          // <-- the IPs used by the Agent to submit APM data to Datadog
    "logs": {...},                         // <-- the IPs used by the Agent to submit logs to Datadog
    "process": {...},                      // <-- the IPs used by the Agent to submit process data to Datadog
    "orchestrator": {...},                 // <-- the IPs used by the Agent to submit container data to Datadog
    "remote-configuration": {...},         // <-- the IPs used by the Agent to retrieve its dynamic configuration
    "synthetics": {...},                   // <-- the source IPs used by Synthetic workers (not used by the Agent)
    "synthetics-private-locations": {...}, // <-- the IPs used by Synthetics Private Locations workers to submit data to Datadog (not used by the Agent)
    "webhooks": {...}                      // <-- the source IPs used by Datadog to connect to 3rd party infrastructure over HTTP (not used by the Agent)
}

Each section has a dedicated endpoint, for example:

• https://ip-ranges./logs.json for the IPs used to receive logs data over TCP.
• https://ip-ranges./apm.json for the IPs used to receive APM data.

Inclusion

Add all of the ip-ranges to your inclusion list. While only a subset are active at any given moment, there are variations over time within the entire set due to regular network operation and maintenance.

Open ports

Open the following ports to benefit from all the Agent functionalities:

Outbound

Inbound

Used for Agent services communicating with each other locally within the host only.

Configure ports

If you need to change an inbound port because the default port is already in use by an existing service on your network, edit the datadog.yaml configuration file. You can find most of the ports in the Advanced Configuration section of the file:

## @param expvar_port - integer - optional - default: 5000
## @env DD_EXPVAR_PORT - integer - optional - default: 5000
## The port for the go_expvar server.
#
# expvar_port: 5000

## @param cmd_port - integer - optional - default: 5001
## @env DD_CMD_PORT - integer - optional - default: 5001
## The port on which the IPC api listens.
#
# cmd_port: 5001

## @param GUI_port - integer - optional
## @env DD_GUI_PORT - integer - optional
## The port for the browser GUI to be served.
## Setting 'GUI_port: -1' turns off the GUI completely
## Default is:
##  * Windows & macOS : `5002`
##  * Linux: `-1`
##
#
# GUI_port: <GUI_PORT>

The APM receiver and the DogStatsD ports are located in the Trace Collection Configuration and DogStatsD Configuration sections of the datadog.yaml configuration file, respectively:

## @param dogstatsd_port - integer - optional - default: 8125
## @env DD_DOGSTATSD_PORT - integer - optional - default: 8125
## Override the Agent DogStatsD port.
## Note: Make sure your client is sending to the same UDP port.
#
# dogstatsd_port: 8125

[...]

## @param receiver_port - integer - optional - default: 8126
## @env DD_APM_RECEIVER_PORT - integer - optional - default: 8126
## The port that the trace receiver should listen on.
## Set to 0 to disable the HTTP receiver.
#
# receiver_port: 8126

Using proxies

For a detailed configuration guide on proxy setup, see Agent Proxy Configuration.

Data buffering

If the network becomes unavailable, the Agent stores the metrics in memory. The maximum memory usage for storing the metrics is defined by the forwarder_retry_queue_payloads_max_size configuration setting. When this limit is reached, the metrics are dropped.

Agent v7.27.0 or later stores the metrics on disk when the memory limit is reached. Enable this capability by setting forwarder_storage_max_size_in_bytes to a positive value indicating the maximum amount of storage space, in bytes, that the Agent can use to store the metrics on disk.

The metrics are stored in the folder defined by the forwarder_storage_path setting, which is by default /opt/datadog-agent/run/transactions_to_retry on Unix systems, and C:\ProgramData\Datadog\run\transactions_to_retry on Windows.

To avoid running out of storage space, the Agent stores the metrics on disk only if the total storage space used is less than 80 percent. This limit is defined by forwarder_storage_max_disk_ratio setting.
