Hologres:Grafana

Prerequisites

Before you begin, make sure you have:

• A running Hologres instance

• The public endpoint of your Hologres instance — go to the Hologres console, open the instance details page, and copy the endpoint from the Network Information section

• An AccessKey ID and AccessKey secret — see Create an AccessKey pair

• The name of the Hologres database you want to query

• Grafana installed — see the Grafana installation guide

Connect Hologres to Grafana

1. Log on to Grafana. In the navigation pane on the left, click Add new connection, select Data Source, and then click PostgreSQL.

   

2. On the PostgreSQL Connection page, fill in the connection parameters.

   

   Parameter	Description
   Host URL	The public endpoint of your Hologres instance.
   Database name	The name of the Hologres database.
   Username	The AccessKey ID of your Alibaba Cloud account.
   Password	The AccessKey secret of your Alibaba Cloud account.
   TLS/SSL Mode	Determines whether a secure SSL/TLS connection is negotiated with the server. Set based on whether SSL is enabled for your endpoint.
   Version	Set to 11. This tells Grafana which PostgreSQL-compatible functions are available in the query builder.

   For all other parameters, see the Grafana PostgreSQL data source documentation.

3. Click Save & Test at the bottom of the page. A Database Connection OK message confirms the connection is successful.

What's next

After connecting Hologres to Grafana, you can:

• Build queries and visualize your Hologres data using the Grafana query editor

• Create dashboards and panels to monitor your data in real time

• Use template variables to build dynamic, reusable dashboards

• Set up alerts based on your Hologres data

For details on these operations, see the Grafana getting started guide.
