# Start services and validate

After initialization is completed and all the services are installed, OpenIAM starts automatically. However, there is a need to conduct health checks and validation.

### Monitor the startup process

Containers may take 8–15 minutes to start. The UI typically starts last.

To check services, use the OpenIAM CLI as follows.

```bash
openiam-cli status
```

Example output:

```
Openiam Status report
[OK] - openiam-esb - Service working. Application status: [ UP ]
[OK] - workflow - Service working. Application status: [ UP ]
...
[OK] - openiam-reportviewer - Service working. Application status: [ UP ]
```

Verify `nginx`:

```bash
systemctl status nginx
```

Logs:

* OpenIAM logs:

```bash
cd /usr/local/openiam/logs
cd /usr/local/openiam/ui/logs/
```

* Infrastructure logs:

Check `/var/log` or run:

```bash
journalctl -u <service name>
```

### Validate the startup

Validate that the UI is up:

```bash
curl -k -I -L http://127.0.0.1/idp/login
```

Expected example response:

```bash
HTTP/1.1 200
Date: Fri, 21 Feb 2025 21:49:04 GMT
Server: Apache/2.4.61 (Red Hat Enterprise Linux) OpenSSL/3.2.2
...
Content-Length: 4970
Set-Cookie: SESSION=...
```

An HTTP 200 response indicates that the application is up and ready for login.

### OpenIAM CLI and useful commands

Run the CLI without arguments to see usage:

```bash
openiam-cli
```

Example output:

{% code overflow="wrap" %}

```bash
Usage: /usr/bin/openiam-cli {start|stop|status|init|log|log <service_name>|list-connectors|list-source-adapters}
```

{% endcode %}

Common commands:

* Check status:

```bash
openiam-cli status
```

* Check service logs:

```bash
openiam-cli log openiam-esb
```

* Stop OpenIAM:

```bash
openiam-cli stop
```

* Start OpenIAM:

```bash
openiam-cli start
```

Health checks:

* ESB:

```bash
curl http://localhost:9080/openiam-esb/actuator/health
```

* UI:

```bash
curl -k http://localhost:9080/idp/actuator/health
```
