OpenTelemetry

Send data using OpenTelemetry

Last9 is fully OpenTelemetry compatible. OpenTelemetry is an open-source observability framework. It provides a standardized way to collect and export telemetry data — metrics, logs, and traces — from your applications and infrastructure.

If you are instrumenting code for the first time, we recommend using OpenTelemetry. You can either run OpenTelemetry Collector or send the telemetry directly from applications using the SDKs. Last9 supports both gRPC and HTTP endpoints for OpenTelemetry.

Using OTel Collector

If your code is already instrumented using Prometheus, statsD, Influx, Jaeger, Zipkin, etc, please refer to OpenTelemetry Collector documentation. OTel Collector supports sending metrics, logs, and trace data irrespective of source.

Using OTel SDKs

Logs from Kubernetes Cluster

Obtain OTLP Endpoint & Credentials

Visit the Integrations page
Select OpenTelemetry
Copy the Endpoint URL and the Authorization Header

Obtain OTLP Credentials

Integration guides use two placeholders for these values. Replace them with what you copied:

Placeholder	Value from Integrations → OpenTelemetry
`$last9_otlp_endpoint`	The Endpoint URL, for example `https://otlp-aps1.last9.io:443`
`$last9_otlp_auth_header`	The full Authorization Header value, including the `Basic` prefix: `Basic <base64-credentials>`

For example, OTEL_EXPORTER_OTLP_HEADERS="Authorization=$last9_otlp_auth_header" becomes OTEL_EXPORTER_OTLP_HEADERS="Authorization=Basic <base64-credentials>".

Replace the placeholders before you run a snippet. They look like shell variables, so a shell expands any you leave in to an empty string and the exporter fails to connect or gets 401 Unauthorized. For shell snippets, you can instead set them first:

export last9_otlp_endpoint="<endpoint-url>"
export last9_otlp_auth_header="Basic <base64-credentials>"

Last9’s OTLP compatible endpoint formats are as follows:

HTTP

https://otlp.last9.io #for US-EAST-1 region
https://otlp-aps1.last9.io #for AP-SOUTH-1 region

gRPC

otlp.last9.io:443 #for US-EAST-1 region
otlp-aps1.last9.io:443 #for AP-SOUTH-1 region
