## Start PVE SD
Create a [configuration file](/configuration/defaults/) with the required parameters to connect to your Proxmox VE (PVE) server before you start the service.
```Shell
prometheus-pve-sd -vv --loop-delay 900 -o /etc/prometheus/pve.json
```
## Available Labels
The following list of meta labels can be used to relabel your scrape results:
`__meta_pve_ipv4`
: Discovered IPv4 address or `False` if not found. To discover the IP address either QEMU guest agent or a cloud-init configuration is required.
`__meta_pve_ipv6`
: Discovered IPv6 address or `False` if not found. To discover the IP address either QEMU guest agent or a cloud-init configuration is required.
`__meta_pve_name`
: Name of the node.
`__meta_pve_type`
: Node type, either `qemu` or `lxc`.
`__meta_pve_vmid`
: VMID of the node.
`__meta_pve_cpu`
: Current CPU load of the node.
`__meta_pve_cores`
: Assigned CPU cores for the node.
`__meta_pve_memory`
: Assigned RAM for the node.
`__meta_pve_status`
: Current state of the node.
`__meta_pve_tags`
: A comma-separated list of tags, as set on the node. The label is not getting exported if no tags were found. (Requires PVE 6+)
`__meta_pve_groups`
: Groups discovered from the `Notes` field of the node. Need to be a valid JSON string e.g. `{"groups":["group1","group2"]}`.
## Prometheus configuration
Prometheus needs a basic file service discovery configuration to fetch system metrics from the host's discovered from PVE. Depending on the used metrics exporter the configuration need to be adjusted, using [Telegraf](https://github.com/influxdata/telegraf/#telegraf) a starter configuration might look like this:
```YAML
- file_sd_configs:
- files:
- /opt/prometheus/conf/file_sd/proxmox.json
job_name: telegraf-pve
metrics_path: /metrics
relabel_configs:
- replacement: telegraf
target_label: job
- replacement: ${1}:9273
source_labels:
- __meta_pve_name
target_label: __address__
- source_labels:
- __meta_pve_name
target_label: instance
```
### Use IP address labels
Instead of `__meta_pve_name`, it is also possible to configure Prometheus to use the address provided by `__meta_pve_ipv4` or `__meta_pve_ipv4` for connections:
```YAML
relabel_configs:
- replacement: ${1}:9273
source_labels:
- __meta_pve_ipv4
target_label: __address__
```
### Convert tags to custom labels
Tags of a node exposed by the `__meta_pve_tags` might be useful to build more complex configurations in Prometheus. As an example, an `alert` tag can be extracted to dine alerting routes based on the tag value.
**Example:**
Extract `group` and `alert` from a list of tags like this: `__meta_pve_tags="alert:team-1,group:cluster-1,node:node-1"`
```YAML
relabel_configs:
- source_labels:
- __meta_pve_tags
regex: ".*group:([\w\-_]*)"
target_label: "group"
replacement: "${1}"
- source_labels:
- __meta_pve_tags
regex: ".*alert:([\w\-_]*)"
target_label: "alert"
replacement: "${1}"
```
Use the extracted `alert` label to set an Alertmanager route:
```YAML
routes:
- receiver: "empty"
matchers:
- alert = muted
- receiver: "team-1"
matchers:
- alert = team-1
```
