-> If you need to export the logs of etcd, minio, and pulsar components, you need to add the parameters -e, -m, -u.

 ## Usage
 
 1. Milvus instance name is required to be specified
-
+If Milvus installed by helm, export logs by followings:
 ```shell
 ./export-milvus-log.sh -i my-release
 ```
+If Milvus installed by Milvus operator, flag `-o` is required to export the logs:
+```shell
+./export-milvus-log.sh -i my-release -o
+```
 
 > This command will generate a directory named milvus-log in the current directory.
 > For a pod that have not been restarted, the command will generate a log named ${podname}.log for the pod and store it in `milvus-log`.
 > For a pod that has been restarted, this command will generate a log named ${podname}.log and a log ${podname}-pre.log for the pod.
 
-2. If your milvus is not installed in the k8s default namespace, please specify namespace with `-n`. You can also customize the log storage path with `-p`.
+2. If your milvus is not installed in the k8s default namespace, please specify namespace with `-n`. You can also customize the log storage path with `-d`.
 
 ```shell
-./export-milvus-log.sh -i my-release -n milvus -p ./logs
+./export-milvus-log.sh -i my-release -n milvus -d ./logs
 ```
 
 3. Export the logs of milvus, etcd, minio, and pulsar components.
 
 ```shell
-./export-milvus-log.sh -i my-release -n milvus -p ./logs -e -m -u
+./export-milvus-log.sh -i my-release -n milvus -d ./logs -e -m -p
 ```
 
 4. Export the logs of milvus and Kafka components.
 
 ```
-./export-milvus-log.sh -i my-release -n milvus -p ./logs -k
+./export-milvus-log.sh -i my-release -n milvus -d ./logs -k
 ```
 
 5. Export the logs for only latest 24h.
