Datadog Traceroute
Datadog Traceroute produce traceroute results reflecting real traffic paths.
Support Matrix for IPv4
Linux
| Protocol-Variant | Supported | Traceroute CLI |
|---|---|---|
| ICMP | Yes | traceroute -I |
| UDP | Yes | traceroute |
| TCP SYN | Yes | tcptraceroute |
| TCP SACK | Yes |
Windows
Windows Server:
| Protocol-Variant | Supported | Traceroute CLI |
|---|---|---|
| ICMP | Yes | tracert |
| UDP | Yes | |
| TCP SYN | Yes | |
| TCP SACK | Yes (req. win driver) |
Windows Client:
| Protocol-Variant | Supported | Traceroute CLI |
|---|---|---|
| ICMP | Yes (req. win driver) | tracert |
| UDP | Yes (req. win driver) | |
| TCP SYN | Yes (req. win driver) | |
| TCP SACK | Yes (req. win driver) | |
| TCP SYN SOCKET | Yes |
Note: Default firewall on windows can block the ICMP responses when not using Windows Driver. Note2: TCP syn_socket is only useful for Windows Client without Windows Driver.
macOS
| Protocol-Variant | Supported | Traceroute CLI |
|---|---|---|
| ICMP | Yes | traceroute -I |
| UDP | Yes | traceroute |
| TCP SYN | Yes | tcptraceroute |
| TCP SACK | Yes |
IPv6 Support
IPv6 is only partially supported.
Note: Windows driver is needed for all protocol-variant for IPv6s on server versions.
Publishing Changes
After merging changes to main create a release by:
-
Navigate to the Releases page
-
Click "Draft a new release"
-
You can "Select a tag" using the dropdown or "Create a new tag"
When creating a new tag, make sure to include the
vprefix. For example, if the last release was v0.1.29, your release should be v0.1.30. -
The release title should be the same as the version tag
-
Use "Generate release notes" to fill in the release description
-
Click "Publish release"
This will create a git tag that can now be referenced in other repos. This will trigger go-releaser that will add installable artifacts to the release.
