## Troubleshooting features for CRE
24+
25+
We do include utility pods to peek into KOTS Admin Console underlying database and object storage (Minio).
26+
27+
### rqlite
28+
29+
For database, to peek into `rqlite` database, you can use the following command:
30+
31+
```bash
32+
kubectl port-forward svc/rqlite-ui-service 3000:80
33+
```
34+
35+
And go to http://localhost:3000 to browse the database.
36+
37+
![rqlite-ui](img/rqlite-ui.png)
38+
39+
### Minio
40+
41+
For object storage, to peek into `minio` object storage, you can use the following command:
42+
43+
First, get the WebUI port from `kotsadm-minio-0` pod:
44+
45+
```log
46+
kubectl logs kotsadm-minio-0
47+
...
48+
WebUI: http://10.42.0.11:<port>> http://127.0.0.1:<port>
49+
```
50+
51+
Next, port forward to the WebUI port:
52+
53+
```bash
54+
kubectl port-forward svc/kotsadm-minio <port>:<port>
55+
```
56+
57+
And go to http://localhost:<port> to browse the object storage.
58+
59+
The username is `admin` and the password is the secretkey in `kotsadm-minio` secret.
