The data is stored locally on disk for each Prometheus server, so data is not replicated on new managers or if you schedule Prometheus to run on a new node. Metrics are not kept longer than 24 hours.
> **Warning**: Upgrading UCP from 3.0.x to 3.1.x causes loss of metrics data.
## Deploy Prometheus on worker nodes
To deploy Prometheus on worker nodes in a cluster:
1. Begin by sourcing an admin bundle.
2. Verify that ucp-metrics pods are running on all managers.
```
$ kubectl -n kube-system get pods -l k8s-app=ucp-metrics -o wide
NAME READY STATUS RESTARTS AGE IP NODE
ucp-metrics-hvkr7 3/3 Running 0 4h 192.168.80.66 3a724a-0
```
3. Add a Kubernetes node label to one or more workers. Here we add a label with key "ucp-metrics" and value "".
```
$ kubectl label node 3a724a-1 ucp-metrics=
node "noah-3a724a-1" labeled
```
