## Overview
|
|
|
|
For better tracking and debugging Milvus, the script `export-milvus-log.sh` is provided for exporting all Milvus logs at once. For those pods that have been restarted, this script can export the logs of the running pods and the logs of the previously pods.
|
|
|
|
> Note: This script only works with Milvus installed on k8s cluster.
|
|
>
|
|
>For milvus installed with helm-chart, if `log.persistence.enabled` is set to true (default false), the tool cannot be used to export milvus logs and the log files can be found directly under the path specified by `log.persistence.mountPath`.
|
|
>
|
|
> For Milvus installed with docker-compose, you can use `docker-compose logs > milvus.log` to export the logs.

## 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 `-d`.
|
|
|
|
```shell
|
|
./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 -d ./logs -e -m -p
|
|
```
|
|
|
|
4. Export the logs of milvus and Kafka components.
|
|
|
|
```
|
|
./export-milvus-log.sh -i my-release -n milvus -d ./logs -k
|
|
```
|
|
|
|
5. Export the logs for only latest 24h.
|
|
|
|
```
|
|
./export-milvus-log.sh -i my-release -s 24h
|
|
```
