In your checkData method you could do something like this:

import { timer, of } from 'rxjs';
import { switchMap, catchError } from 'rxjs/operators';

checkData() {
    return timer(0, 10000)
        .pipe(
           switchMap(_ => this.http.get('my url')),
           catchError(error => of(`Bad request: ${error}`))
        );
}

Then your subscribe will get the result of the http call every 10 seconds.
