Exporting to the logger with OpenCensus
Opencensus can export data to the system logger as another exporter. This is not the standard KrakenD Logging, and you should not enable both.
Enabling 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
enabled_layers- Lets you specify what data you want to export. All layers are enabled by default unless you declare this section.
backendboolean- Reports the activity between KrakenD and your servicesDefaults to
false pipeboolean- Reports the activity at the beginning of the proxy layer. It gives a more detailed view of the internals of the pipe between end-users and KrakenD, having into account merging of different backends.Defaults to
false routerboolean- Reports the activity between end-users and KrakenDDefaults to
false
reporting_periodinteger- 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 sample_rateinteger- 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
