The SignalFx output plugin for Fluent Bit sends log-based metrics to SignalFx. Refer to the SignalFx Fluent Bit integration documentation for details.
AWS recommends that you store sensitive information (like your SignalFx Token) using secretOptions as shown in the example task definition. This is optional - it is also valid to simply specify the Token in the options map:
"logConfiguration": {
"logDriver": "awsfirelens",
"options": {
"Name": "SignalFx",
"MetricName": "com.firelens.example",
"MetricType": "counter",
"Dimensions": "ecs_cluster, container_name",
"Token": "XXXXXXXXXXXX"
}
}
