10/07/2024, 4:54 PMThis looks fine to me. Are you not seeing
requests_countz
Zack
10/07/2024, 5:06 PMI'm not. perhaps I need to have this running at the same time?
const sdk = new NodeSDK({
traceExporter: exporter,
instrumentations: [getNodeAutoInstrumentations()],
resource: new Resource({
[SemanticResourceAttributes.SERVICE_NAME]: "event-processor", // Replace with your service name
}),
});
sdk.start();
I do have an agent running through kubernetes that is sending logs but perhaps these are separate requirements.

10/07/2024, 5:49 PMYou only need to do one of the things
• You are setting up the SDK all by yourself here https://signoz-community.slack.com/archives/C06T3T7QESD/p1728314831723769?thread_ts=1728314737.228039&cid=C06T3T7QESD
• You are using a little wrapper here https://signoz-community.slack.com/archives/C06T3T7QESD/p1728320806562709?thread_ts=1728314737.228039&cid=C06T3T7QESD.

10/08/2024, 1:31 PMCan you try using ConsoleExporter in dev and check it writes metrics to stdout?
