[Feature request] Add ability to configure log level for instrumentConsole

[romap0]

It would be useful to have the ability to pass console log methods which will be added to breadcrumbs.

For example:

Sentry.init({
  breadcrumbConsoleLevels: ['trace', 'debug', 'info'],
});

You can use the beforeBreadcrumb hook to customize what breadcrumbs show up. https://docs.sentry.io/platforms/javascript/enriching-events/breadcrumbs/#customize-breadcrumbs

Sentry.init({
  // ...

  beforeBreadcrumb(breadcrumb, hint) {
    if (breadcrumb.category === "console") {
        // add logic to control what breadcrumbs are here
    }

    return breadcrumb;
  },
});

See what it looks like here:

sentry-javascript/packages/browser/src/integrations/breadcrumbs.ts

Lines 132 to 141 in 1d1b41c

	private _consoleBreadcrumb(handlerData: { [key: string]: any }): void {
	const breadcrumb = {
	category: 'console',
	data: {
	arguments: handlerData.args,
	logger: 'console',
	},
	level: Severity.fromString(handlerData.level),
	message: safeJoin(handlerData.args, ' '),
	};

@kamilogorek Do you think we should expand the API to add this? Not sure if it's worth the bundle size increase.

@AbhiPrasad Thanks for your reply.

beforeBreadcrumb hook can be used to filter extra console methods, but with it I can`t add a trace level.

Now as a workaround I use this after Sentry initialization:

fill(global.console, 'trace', (originalConsoleLevel) => (message, ...args) => {
  Sentry.addBreadcrumb({
    category: 'console',
    level: Sentry.Severity.Debug, // <-- there is not a trace severity, so debug is used
    message,
    data: { level: 'trace', args },
  });

  if (originalConsoleLevel) {
    Function.prototype.apply.call(originalConsoleLevel, global.console, [message, ...args]);
  }
});

@romap0 you can add trace here

sentry-javascript/packages/utils/src/instrument.ts

Line 118 in 88b96f6

['debug', 'info', 'warn', 'error', 'log', 'assert'].forEach(function(level: string): void {

and I'll happily merge it :)
