+## Grafana password
+Custom password could be sent via grafana charts values:

+```

+Currently Grafana allow you to expose ingress via helm charts. Below code need to be added in Grafan config section to the values.yaml:
+
+```
+grafana
+  ingress:
+    enabled: true
+    path: /
+    hosts:
+      - grafan-jmeter.example.com
+```
+
+## Access grafana via port-forwarding
+
+```
+kubectl port-forward service/HELM_RELEASE_NAME-grafana 30080:80
+
+```
+`HEAL_RELEASE_NAME` was provided during stack deploy ( helm `-n` option). Grafana should be enabled via [localhost url](http://localhost:30080)
