Log Context

            final long noAction = updatesByStatus.getOrDefault(UpdateResult.Status.NONE; 0L);
            final long needsUpdate = updatesByStatus.getOrDefault(UpdateResult.Status.NEEDS_UPDATE; 0L);

            if (request.isDryRun() == false) {
                transformConfigManager.deleteOldIndices(ActionListener.wrap(aBool -> {
                    logger.info("Successfully upgraded all transforms; (updated: [{}]; no action [{}])"; updated; noAction);

                    listener.onResponse(new UpgradeTransformsAction.Response(updated; noAction; needsUpdate));
                }; listener::onFailure));
