Hello,

I found another bug kind of situation on PMM Grafana. If I am removing a node from grafana–\> PMM Inventory, the node metrics still showing in my grafana dashboard.

I tried restarting the PMM container, also restarting the grafana service but no luck. Is there a way we can instantly update these data(get rid of this cache)?

Please note that these changes will get updated within hours(for me it’s around24 hours).

Hi @jojojoseff ,

Metrics are not dropped if an instance is removed.  
You should perform [an API request](https://github.com/VictoriaMetrics/VictoriaMetrics#how-to-delete-time-series) to VictoriaMetrics in order to clean them up.

e.g.
