The directory can grow large when remote storage is unavailable for extended periods of time and if `-remoteWrite.maxDiskUsagePerURL` isn't set.
If you don't want to send all the data from the directory to remote storage, simply stop `vmagent` and delete the directory.
* If you see `skipping duplicate scrape target with identical labels` errors when scraping Kubernetes pods, then it is likely these pods listen multiple ports.
Just add the following relabeling rule to `relabel_configs` section in order to filter out targets with unneeded ports:
```yml
- action: keep_if_equal
source_labels: [__meta_kubernetes_pod_annotation_prometheus_io_port, __meta_kubernetes_pod_container_port_number]
```
* If you see `skipping duplicate scrape target with identical labels` errors when scraping Kubernetes pods, then it is likely these pods listen multiple ports or they use init container.
To determinate duplicated targets during service discovery you can use followin pattern:
```yml
...
- job_name: my-app
metrics_path: /metrics
scheme: http
kubernetes_sd_configs:
- role: pod
namespaces:
names:
- kube-system
relabel_configs:
- action: keep
regex: my-app
source_labels: [__meta_kubernetes_pod_label_app]
- action: labelmap
regex: __meta_(.*)
```
To filter out targets with init container add the following relabeling rule to `relabel_configs` section:
```yml
- action: keep
regex: false
source_labels: [__meta_kubernetes_pod_container_init]
```
To filter out targets with unneeded ports add the following relabeling rule to `relabel_configs` section:
```yml
- action: keep_if_equal
source_labels: [__meta_kubernetes_pod_annotation_prometheus_io_port, __meta_kubernetes_pod_container_port_number]
```
