 ## Startup logs
 
-Tracer startup logs capture all obtainable information at startup and log it as `DATADOG TRACER CONFIGURATION`, `DATADOG TRACER DIAGNOSTICS`, or `DATADOG CONFIGURATION` to simplify searching within your logs.
+Tracer startup logs capture all obtainable information at startup and log it as `DATADOG TRACER CONFIGURATION`, `DATADOG TRACER DIAGNOSTICS`, `DATADOG ERROR`, or `DATADOG CONFIGURATION` to simplify searching within your logs.
 
 Some languages log to a separate file depending on language conventions and the safety of accessing `Stdout` or equivalent. In those cases, the location of logs are noted in the language tab below. Some languages don't log diagnostics entries, also noted below.
 
 `CONFIGURATION` logs are a JSON formatted representation of settings applied to your tracer. In languages where an Agent connectivity check is performed, the configuration JSON will also include an `agent_error` key, which indicates whether the Agent is reachable.
 
-`DIAGNOSTICS` log entries, in the languages that produce them, happen when the tracer encounters an error during application startup. If you see `DIAGNOSTICS` log lines, confirm from the indicated log that settings and configurations are applied correctly.
+`DIAGNOSTICS` or `ERROR` log entries, in the languages that produce them, happen when the tracer encounters an error during application startup. If you see `DIAGNOSTICS` or `ERROR` log lines, confirm from the indicated log that settings and configurations are applied correctly.
 
 If you do not see logs at all, ensure that your application logs are not silenced and that your log level is at least `INFO` where applicable.
