Hello naren951,
You can check, if the corresponding assets exist in the chunk:
chunk.point_cloud, chunk.depth_maps, chunk.dense_cloud, chunk.model, chunk.elevation, chunk.orthomosaic, chunk.tiled_model.
then access it's meta information:
chunk.meta, chunk.point_cloud.meta, chunk.dense_cloud.meta and etc. it contains the information about the processing parameters used and time spent on the corresponding processing stage.
