Vercel

Vercel (Syslog integration)  -->  OpenTelemetry Collector (syslog receiver)  -->  Mezmo OTEL Source (otlphttp exporter)

​

Set Up the OpenTelemetry Collector

1. Log in to the Mezmo Web App, create (or open) a Pipeline, and add an OpenTelemetry Source. Note the ingestion key — you’ll use it as apikey.
2. Download the otelcol-contrib distribution, which includes the syslog receiver, from the OpenTelemetry website.
3. Create a config.yaml and run the Collector somewhere reachable from Vercel’s infrastructure over the public internet:

receivers:
  syslog:
    protocol: rfc5424
    tcp:
      listen_address: "0.0.0.0:514"

exporters:
  otlphttp/mezmo:
    endpoint: "https://logs.mezmo.com/otel"
    compression: gzip
    headers:
      apikey: "<YOUR_INGESTION_KEY>"

service:
  pipelines:
    logs:
      receivers: [syslog]
      exporters: [otlphttp/mezmo]

4. Start the Collector:

./otelcol-contrib --config /path/to/config.yaml

​

Configure the Vercel Integration

1. In the Vercel dashboard, add the Mezmo integration as an Add-on.
2. When prompted for a Syslog URL, enter the address and port where your OTel Collector’s syslog receiver is publicly reachable.
