Thanks @RastogiAbhijeet for opening this issue!
Can you please clarify why you need a direct reference for LogSeverity? What are you plans for using it?

Hey @losalex ,

My use case is pretty straightforward,
I want to enforce a strict type on the severity argument passed to the wrapper function I have written for the writing logs to Cloud Run stdout.

Currently the Severity enum exported by the @gooogle-cloud@logging node-module is mapping to numbers.

# Referred from the node modules
export declare enum Severity {
    emergency = 0,
    alert = 1,
    critical = 2,
    error = 3,
    warning = 4,
    notice = 5,
    info = 6,
    debug = 7
}

I can maybe also use SeverityName which can help me to get the severity names ( as I would expect ) but it does so in the lower case.

But the issue with both cases is that the severity is not properly reflected in the Cloud Log Explorer in the GCP console.

So for eg:
I pass -> 2 for critical severity, the cloud log shows it as Severity "Default".

Now if you look at this link, it will show the correct number that should be used for the severity. https://cloud.google.com/logging/docs/reference/v2/rest/v2/LogEntry#logseverity.

Another reason why I started to chase LogSeverity is because as I digged into the
LogEntry Type in the node-module, you'd see that the severity in the metadata says -> LogSeverity and not Severity.

export type LogEntry = Omit<google.logging.v2.ILogEntry, 'timestamp' | 'severity' | 'httpRequest'> & {
    timestamp?: Timestamp | null;
    severity?: LogSeverity | null;
    httpRequest?: HttpRequest | null;
};

Ofcourse, I might be looking at the wrong place but how the types are being managed so of didn't make a lot of sense.

Honestly, I would label this as a bug and hope it gets fixed.

Hope it helps. Happy to chat through it if anything above didn't make sense.

If you are interested in just the enum type, you can try something like

import { Entry } from '@google-cloud/logging';

export type LogSeverityType = Exclude<
  NonNullable<Entry['metadata']['severity']>,
  string
>;

But if you want the enum values, I am not sure if that's possible without explicit export. I asked this SO question in case it's possible.
