NoticeError(exception $exception[, IDictionary $attributes]) NoticeError(string $error_message, IDictionary $attributes)
Notice an error and report to New Relic, along with optional custom attributes.

Requirements

Compatible with all agent versions.

Compatible with all app types.

Description

Notice an error and report it to New Relic along with optional custom attributes. For each transaction, the agent only retains the exception and attributes from the first call to NoticeError(). You can pass an actual exception, or pass a string to capture an arbitrary error message.

If this method is invoked within a transaction, the agent reports the exception within the parent transaction. If it is invoked outside of a transaction, the agent creates an error trace and categorizes the error in the New Relic UI as a NewRelic.Api.Agent.NoticeError API Call.

The agent adds the attributes only to the traced error, and does not send them to New Relic Insights. To add custom attributes to Insights, see AddCustomParameter().
