Provider Monitoring

There are several services running on the Provider VM that are central to the operation of the Provider and VMware Data Services Manager. VMware Data Services Manager collects health data for each Provider in your installation, and for each core service running in the Provider VM.

Note: You can monitor the health of the Provider only via the VMware Data Services Manager API. It is your responsibility to choose a tool and to configure it to monitor the VMware Data Services Manager console endpoint.

Querying Provider Health

Invoke the /appliance/providerhealth endpoint of the VMware Data Services Manager API to query the health (UP or DOWN) of the Provider node:

GET https://<provider-ip-address>/appliance/providerhealth

Note: You must add the Provider Authorization --header as a Bearer token when you make the request.

Sample response excerpt:

{
    "id": "8a6cf2d7-187f-41b1-96f3-adbd74d5af20",
    "nodeId": "7fd97971-f6b8-4f04-b931-231a55dc3a48",
    "status": "UP",
    "createdTime": 1614692472208
},

VMware Data Services Manager returns the Provider node health in the response status.

Querying the Status of Provider Core Services

The /appliance/status endpoint of the VMware Data Services Manager API returns the status (ACTIVE, INACTIVE, FAILED) of the core services running on the Provider node:

GET https://<provider-ip-address>/appliance/status

Sample response excerpt:

{
    "postgres": "ACTIVE",
    "rabbitMQ": "ACTIVE",
    "provider": "ACTIVE",
    "monitoring": "ACTIVE",
    "apms": "ACTIVE",
    "updateManager": "ACTIVE"
    "rclone": "ACTIVE"
}

Troubleshooting

If you find that a Provider node is DOWN, restarting an INACTIVE or FAILED core service on the Provider VM may rectify the situation.

The table below identifies the mapping between each /appliance/status response parameter and the (VM OS) service name:

providerhealth Response Parameter	Description	VM OS Service Name
postgres	Internal vPostgres database	vpostgresql
rabbitMQ	RabbitMQ service	rabbitmq-server
provider	Provider service	provider
monitoring	Monitoring service	monitoring
apms	Appliance management service	apms
updateManager	Update manager service	update-manager
rclone	rclone service	rclone

Procedure

Perform the following procedure for a Provider node with DOWN status:

Get the status of the services running on the Provider.
```
GET https://<provider-ip-address>/appliance/status
```
Examine that reponse, and identify any services with INACTIVE or FAILED status.
SSH into the Provider VM.

Restart each affected service. For example:

user@providervm$ systemctl restart update-manager.service

Check the Provider service status again.
```
GET https://<provider-ip-address>/appliance/status
```
Ensure that all services are in the ACTIVE state.
