Example of how to log all of the EE hooks 'fired' on a request. You need to enable WP_DEBUG and WP_DEBUG_LOG for this to write the hooks to /wp-content/debug.log

ee_hooks_log.php

<?php

//Debug function to easily write various vars to the log.
if ( ! function_exists('write_log')) {
   function write_log ( $log )  {
      if ( is_array( $log ) || is_object( $log ) ) {
         error_log( print_r( $log, true ) );
      } else {
         error_log( $log );
      }
   }
}

//Add all of the EE hooks into arrays used for logging later.
add_action('all', function(){ 
    global $AHEE, $FHEE, $EEHooks;

    $cf = current_filter();
    
    $AHEE = is_array( $AHEE ) ? $AHEE : array();
    $FHEE = is_array( $FHEE ) ? $FHEE : array();
    $EEHooks = is_array( $EEHooks ) ? $EEHooks : array();

    if ( strpos($cf, 'AHEE__') === 0 ) {
        if(! in_array($cf, $AHEE) ) {
            //Split out AHEE's
            $AHEE[] = $cf;
            //Add every hook to an array.
            $EEHooks[] = $cf;
        }
    } elseif ( strpos($cf, 'FHEE__') === 0 ) {
        if(! in_array($cf, $FHEE) ) {
            //Split out AHEE's
            $FHEE[] = $cf;
            //Add every hook to an array.
            $EEHooks[] = $cf;
        }
    }
});

//Log all of the EE hooks fired on this request.
add_action('shutdown', function(){
    global $AHEE, $FHEE, $EEHooks;
    
    if( !empty($AHEE) || !empty($FHEE) ) {
        write_log(
            array(
                'AHEE (Actions Hooks)' => $AHEE,
                'FHEE (Filter Hooks)' => $FHEE,
                'All EE hooks' => $EEHooks
            )
        ); 
    }
});
