✔ Installed grafana-piechart-panel successfully 
</code></pre>
<p>But whenever i visit my dashboard, unable to see plugin. Is there any addintional things to done ? please guide. any help will be appreciated.</p>

<p>You will need to run <code>service grafana-server restart</code>.</p>
<p>If you're using <a href="https://github.com/grafana/helm-charts/tree/main/charts/grafana" rel="nofollow noreferrer">this</a> grafana helm chart, you might as well just add the plugins you need in the <code>plugins</code> parameter. See <a href="https://github.com/grafana/helm-charts/blob/grafana-6.32.12/charts/grafana/values.yaml#L482" rel="nofollow noreferrer">this</a></p>
<p>This will help you in automating stuff and not rely on manual <code>kubectl exec</code> runs post chart installation.</p>
