ddflare Extension
The ddflare extension component allows inclusion of otel-agent data in the datadog-agent flare. A flare can be triggered by the core agent process, or remote-config.
The ddflare extension also provides the relevant metadata for otel-agent configuration and inventory tracking in Fleet Automation. This metadata is periodically collected by the core-agent which then submits that data to the backend.
Extension Configuration
The datadogextension will be added automatically by the converter component. If you opted out of the converter, or you want to change the defaults, you are able to configure the extension as so:
Collector config:
extensions:
datadog:
port: 7777
Agent Config:
otel-agent:
enabled: true
flare_port: 7777
The port is the location in which the otel-agent will expose the data required to build the flare. The core agent then fetches the data from this port.
Data collected by flare
Configurations
The flare will collect both the provided collector config and the enhanced config (enhanced via converter).
The provided collector configs can be found in otel/otel-flare/customer.cfg and the enhanced config can be found in otel/otel-flare/customer.cfg.
Environment variables
The flare will collect all environment variables, and these can be found in otel/otel-flare/environment.json.
Extension data
The flare also adds data collected from extensions. These extensions are added automatically by the converter component. The data collected is from extensions:
- health_check: Found in
otel/otel-flare/health_check.
Contains a JSON of the latest health check, for example:
{"status":"Server available","upSince":"2024-08-14T14:54:00.575804+02:00","uptime":"28.470434291s"}
- pprof: Found in
otel/otel-flare/pprof
Contains a allocs (dd-autoconfigured_debug_pprof_allocs), heap (dd-autoconfigured_debug_pprof_heap) and cpu (dd-autoconfigured_debug_pprof_profile) profile. Profiles can be opened with the pprof tool, e.g.
go tool pprof -http=: otel/otel-flare/pprof/dd-autoconfigured_debug_pprof_heap.dat
- zpages: Found in
otel/otel-flare/zpages
Contains extension (dd-autoconfigured_debug_extensionz), feature (dd-autoconfigured_debug_featurez), pipeline (dd-autoconfigured_debug_pipelinez), service (dd-autoconfigured_debug_servicez) and trace (dd-autoconfigured_debug_tracez) data. The data is in html format, and can be input in a html viewer.
Logs
The flare will collect the otel-agent logs which can be found in logs/otel-agent.log.
Raw data
The raw response can be found in otel-response.json. This corresponds to the data that is exposed at the datadog extensions port.
Data collected for inventory
The ddflare extension submits a variety of metadata for fleet automation including version, command, configuration. You can find more information about the Inventory Agent Payload in comp/metadata/inventoryotel/README.md.
