Grafana

Grafana is integrated in the Intelligence Center to display OpenTSDB data and Elasticsearch data.

Please refer to https://grafana.com//) for Grafana installation Please refer to https://docs.grafana.org/installation/configuration/ for Grafana configuration

Application groups in UAV correspond to organizations in grafana. The user of UAV is granted with the same access permission to application groups as to organizations in Grafana.

AppHub and Grafana Mapping

Finish steps below after installing Grafana and keep it connected to AppHub:

1. Adjust Grafana Configuration

Disallow sign-out, disallow registration, default org setting, default org access permission configuration, and menu access permission of ordinary users. Below are references:

2. Grafana Creates Exclusive API User for AppHub

Sign in Grafana with Admin account (refer to Grafana configuration file for the username and password of Admin) for user operation

Create API user

Edit API user

Check Admin permissions

3. Configure AppHub web.xml

param-value of param-name (uav.apphub.sso.grafana.connection.info): 
{
"api.url": "http://127.0.0.1:3000",
"web.url": "http://127.0.0.1:3000",
"datasource.opentsdb.url": "http://127.0.0.1:4243",
"datasource.elasticsearch.url": "http://127.0.0.1:9200",
"authorization.loginId": "apiuser",
"authorization.loginPwd": "apiuser",
"authorization.register.defPwd": "1q@W3e",
"authorization.register.sleep.time": "2000"
}

Fields: 

"api.url": Grafana access address for API call
"web.url": login address (such as domain name) of Grafana after authorization
"datasource.opentsdb.url": OpenTSDB access address for dashboard creation
"datasource.elasticsearch.url": ES access address for dashboard creation
“authorization.loginId”: exclusive API user account of Grafana
"authorization.loginPwd": exclusive API password of Grafana
"authorization.register.defPwd": uniform and default user password of Grafana for automatic registration
"authorization.register.sleep.time": time intervals between threads when AppHub accesses Grafana API. Asynchronous invocation requires requests to be accomplished with interactions.

Initialize Dashboards

Application clusters of UAV correspond to dashboards of Grafana. Initialize dashboards of application clusters in the Intelligence Center management page.
