context.log.metric is always undefined

[dixitsuneel]

In the dev environment, when I look at the context.log.metric it comes out to be undefined.

Can you guys please correct the documentation and provide the correct way to track the metric.

@mike-urnun-msft Is there any update on this?

Hi @dixitsuneel

Apologies for delay in response. This section of the documentation that discusses the use of context.log.metric method seems to have been published in an error. Although, the Functions team is working on this feature and you may track & inquire about it here: Azure/azure-functions-nodejs-worker#147

In the meantime, please explore using the Application Insights SDK instead for your NodeJS Functions runtime as explained here: https://docs.microsoft.com/en-us/azure/azure-functions/functions-monitoring#custom-telemetry-in-javascript-functions

Lastly, we are proceeding to assign this issue to the author to review further and take the right course of action for the said section of this documentation. If there are further questions regarding this matter, please don't hesitate to reach out and we will gladly continue the discussion.
