# Glances can't start --export prometheus with the -w
Your current Glances systemd service is trying to start both the **Web UI** (`-w`) and the **Prometheus exporter** (`--export prometheus`) at the same time, but Glances doesn’t natively support running both in a single process.
### **Solution: Run Two Separate Instances of Glances**
You'll need to create **two systemd service files**, one for the Web UI and another for the Prometheus Exporter.
#### Create a Service for Glances Web UI
Run
```bash
sudo nano /etc/systemd/system/glances.service
```
Paste
```bash
[Unit]
Description=Glances Web UI
After=network.target
[Service]
Type=simple
ExecStart=/usr/local/bin/glances -w
Restart=on-failure
[Install]
WantedBy=multi-user.target
```
Save and exit.
#### Create a Service for Glances Prometheus Exporter
run
```bash
sudo nano /etc/systemd/system/glances-prometheus.service
```
paste
```bash
[Unit]
Description=Glances Prometheus Exporter
After=network.target
[Service]
Type=simple
ExecStart=/usr/local/bin/glances --export prometheus
Restart=on-failure
[Install]
WantedBy=multi-user.target
```
Save and exit.
#### Reload Systemd and Start Services
```bash
sudo systemctl daemon-reload
sudo systemctl enable glances-prometheus
sudo systemctl start glances-prometheus
```
Verify That Both Are Running
```shell
systemctl status glances-web glances-prometheus
```
Now, you can access:
- **Web UI** at `http://:61208`
- **Prometheus metrics** at `http://:9091/metrics`
This should work smoothly.
