OpenTelemetry

Most recent version: v0.0.1

See the changelog of this Sink here.

Overview

The OpenTelemetry Data sink allows Onum to send data in OpenTelemetry Protocol, including Metrics, Traces, and Logs.

Configuration

Now you need to specify how and where to send the data, and how to establish a connection with your database.

Metadata

Enter the basic information for the new Data sink.

Parameters	Description
Name*	Enter a name for the new Data sink.
Description	Optionally, enter a description for the Data sink.
Tags	Add tags to easily identify your Data sink. Hit the Enter key after you define each tag.

---

Metrics

Decide whether or not to include this Data sink info in the metrics and graphs of the Home area.

Configuration

Now add the configuration to establish the connection.

Parameter	Description
Protocol*	Choose the desired protocol to send your data: gRPC HTTP
Endpoint*	Enter the endpoint to send your data.
Port*	Specify the required port.
Use gzip Compression	Set this option to true if you want to compress your data in gzip format.
Send timeout in ms	Set the milliseconds to wait for data to be successfully transmitted before terminating the attempt.
Send Traces*	Set this option to true if you want to send Traces to your OpenTelemetry account. If you select the HTTP sending protocol, you'll be prompted to optionally include your HTTP Traces Path.
Send Metrics*	Set this option to true if you want to send Metrics to your OpenTelemetry account. If you select the HTTP sending protocol, you'll be prompted to optionally include your HTTP Metrics Path.
Send Logs*	Set this option to true if you want to send Logs to your OpenTelemetry account. If you select the HTTP sending protocol, you'll be prompted to optionally include your HTTP Logs Path.

Depending on the type(s) of data you're sending (Traces, Metrics, and/or Logs), your events must have a specific set of information in OpenTelemetry format. Check an example for every data type below:

Batch Configuration

Set this option to true and fill the following options to establish batch configuration:

Parameters	Description
Minimum amount of data points to be sent	Set the minimum amount of data points used to send the batch. Does not establish a real maximum, just a trigger. The default value is 8192.
Sizer*	Decide whether to set the limit in bytes or items.
Min size of the batch	Set the minimum capacity of the batch.
Max size of the batch	Set the maximum capacity of the batch. It must be higher than the minimum set above. The default value is 0 and there's not a maximum limit.

Parameters	Description
Certificate*	This is the predefined TLS certificate.
Private Key*	The private key of the corresponding certificate.
CA Chain*	The path containing the CA certificate
Minimum TLS Version*	Minimum TLS version to use for your connection.
