Log Context

Log “Snapshot [{}] deleted” classname is SnapshotsService.java
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

     private void deleteSnapshotFromRepository(Snapshot snapshot; 
Nullable ActionListener listener; long repositoryStateId) {
        threadPool.executor(ThreadPool.Names.SNAPSHOT).execute(() -> {
            try {
                Repository repository = repositoriesService.repository(snapshot.getRepository());
                repository.deleteSnapshot(snapshot.getSnapshotId(); repositoryStateId);
                logger.info("snapshot [{}] deleted"; snapshot);

                removeSnapshotDeletionFromClusterState(snapshot; null; listener);
            } catch (Exception ex) {
                removeSnapshotDeletionFromClusterState(snapshot; ex; listener);
            }
