Use standard logging instead
Unless you have a compelling reason to use this logger based on OpenCensus, you should use the standard KrakenD Logging and not this component. This component is deprecated and will be removed in the future.
Opencensus can also export data to the system logger as other exporters. If you use this component, do not not enable standard logging.
To enable OpenCensus logging, it only requires you to add the logger exporter in the opencensus module.
The following configuration snippet enables the logger:
{
"extra_config":{
"telemetry/opencensus": {
"sample_rate": 100,
"reporting_period": 0,
"exporters": {
"logger": {
"stats": true,
"spans": true
}
}
}
}
As with all OpenCensus exporters, you can add optional settings in the telemetry/opencensus level:
Fields of "telemetry/opencensus"
* required fields
| Lets you specify what data you want to export. All layers are enabled by default unless you declare this section.
| ||||||
| The number of seconds passing between reports. If duration is less than or equal to zero, it enables the default behavior of each exporter. Defaults to 0 | ||||||
| A number between 0 (no requests at all) and 100 (all requests) representing the percentage of sampled requests you want to send to the exporter. Sampling the 100% of the requests is generally discouraged when the relationship between traffic and dedicated resources is sparse. Defaults to 0 |
Then, the exporters key must contain an logger entry with the following properties:
Fields of "telemetry/opencensus": { "exporters":{} }
* required fields
