Issue/Introduction
Grafana displays duplicate data for the same instance as shown in the screenshot below.
And you set the Manually configure for the Grafana UI route.
Resolution
This is a known issue in current healthwatch versions and will be fixed in v2.3.2. Please schedule to upgrade to this fix version if possible.
We have another two temporary workarounds if you cannot wait for the upgrade.
Set Automatically configure in TAS for VMs for Grafana UI route: If you are installing Healthwatch on an Ops Manager foundation with TAS for VMs installed, Healthwatch automatically configures a route for the Grafana UI in TAS for VMs. VMware recommends selecting this option when available. You access the Grafana UI by navigating to https://grafana.sys.DOMAIN in a browser window, where DOMAIN is the system domain you configured in the Domains pane of the TAS for VMs tile. For more information, see the TAS for VMs documentation.
