If it's difficult to identify the cause, please send a Flare.

First, change the log_level in datadog.yaml from info to debug.

플랫폼	PATH
AIX	`/etc/datadog-agent/datadog.yaml`
Linux	`/etc/datadog-agent/datadog.yaml`
macOS	`~/.datadog-agent/datadog.yaml`
Windows	`%ProgramData%\Datadog\datadog.yaml`

###########################
## Logging Configuration ##
###########################

## @param log_level - string - optional - default: info
## @env DD_LOG_LEVEL - string - optional - default: info
## Minimum log level of the Datadog Agent.
## Valid log levels are: trace, debug, info, warn, error, critical, and off.
## Note: When using the 'off' log level, quotes are mandatory.
#
log_level: 'debug'

Restart the Agent.

OS		Command
Linux	CentOs/Redhat	`sudo systemctl restart datadog-agent` `sudo restart datadog-agent`
Linux	Ubuntu/Debian	`sudo service datadog-agent restart`
Windows		Run the following command in cmd: `"%ProgramFiles%\Datadog\Datadog Agent\bin\agent.exe" status` Datadog Agent Manager > Restart Agent Right-click the Datadog icon in the Windows tray > Restart
Kubernetes		`kubectl delete pod <AGENT POD NAME>`

Wait 5–10 minutes after restarting, then send the Flare:

플랫폼	Command
Linux	`sudo datadog-agent flare <CASE_ID>`
Windows	Run the following command in cmd: `"%ProgramFiles%\Datadog\Datadog Agent\bin\agent.exe" flare <CASE_ID>` Datadog Agent Manager > Flare > Enter Case ID and Email, then Submit
Kubernetes	`kubectl exec -it <POD_NAME> -- agent flare <CASE_ID>`

- The Case ID entered in the Flare must be the ticket number from Datadog.
Before sending the Flare, register the issue on the Support Portal and obtain a ticket number.
- Enter the email as monitoring_admin@sk.com.

After the Flare is successfully sent, change the log_level back to info and restart the Agent.
If Flare sending fails, attach the generated Flare file to the ticket on the Support Portal.
