Log Context

Log “Reverting to snapshot ‘” classname is TransportRevertModelSnapshotAction.java.
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

         AnomalyDetectorsIndex.createStateIndexAndAliasIfNecessary(client; state; createStateIndexListener);
    }

    private void getModelSnapshot(RevertModelSnapshotAction.Request request; JobResultsProvider provider; Consumer handler;
                                  Consumer errorHandler) {
        logger.info("Reverting to snapshot '" + request.getSnapshotId() + "'");

        provider.getModelSnapshot(request.getJobId(); request.getSnapshotId(); modelSnapshot -> {
            if (modelSnapshot == null) {
                throw new ResourceNotFoundException(Messages.getMessage(Messages.REST_NO_SUCH_MODEL_SNAPSHOT; request.getSnapshotId();
                        request.getJobId()));
