Resolution

Steps to Resolve
For VCF 9.0 and higher

Recommended Action:

Check the status code in the alarm description.
Remediation based on status code:

1. UNAUTHENTICATED:
   1. Use the following API to get the global collector(s)' setting and locate the one which 'collector_type' is VRNI_STREAMING.
      
      Example:
      
      GET https://{MP_IP}/policy/api/v1/infra/ops-global-config



      "operation_collectors": [
          {
              "username": "<user>",
              "password": "<password>",
              "root_certificate": "-----BEGIN CERTIFICATE-----<certificate contents>-----END CERTIFICATE-----",
              "collector_type": "VRNI_STREAMING",
              "collector_ip": "<IP>",
              "collector_port": 50000
          }
      ]

   2. Check if the "username" is configured correctly.
   3. Check if the "password" is configured correctly.
   4. Check if the "root_certificate" is configured correctly.
   5. If any of above fields are not configured correctly, using the following API to correct its value:
      
      Example:
      
      PATCH https://{MP_IP}/policy/api/v1/infra/ops-global-config
      
      

      "operation_collectors": [
          {
              "username": "<user>",
              "password": "<password>",
              "root_certificate": "-----BEGIN CERTIFICATE-----<certificate contents>-----END CERTIFICATE-----",
              "collector_type": "VRNI_STREAMING",
              "collector_ip": "<IP>",
              "collector_port": 50000
          }
      ]

       

2. UNAVAILABLE or DEADLINE_EXCEED:
   1. If there is an extra firewall between Edge node and Aria Operations for Networks streaming collector. Check if there is policy denying the traffic from TN to the collector, since the traffic requires HTTPS(443). 
   2. Using the following API to get the global collector(s)' setting and locate the one which 'collector_type' is VRNI_STREAMING.
      
      Example:
      
      GET https://{MP_IP}/policy/api/v1/infra/ops-global-config
      
      

      "operation_collectors": [
          {
              "username": "<user>",
              "password": "<password>",
              "root_certificate": "-----BEGIN CERTIFICATE-----<certificate contents>-----END CERTIFICATE-----",
              "collector_type": "VRNI_STREAMING",
              "collector_ip": "<IP>",
              "collector_port": 50000
          }
      ]

   3. Check if the "collector_port" field in the API's response is same as {metrics_target_port} in the alarm description.
   4. Check if the "collector_ip" field in the API's response is same as {metrics_target_address} in the alarm description.
   5. If any of above fields are not configured correctly, using the following API to correct its value:
      
      Example:
      
      PATCH https://{MP_IP}/policy/api/v1/infra/ops-global-config
      
      

      "operation_collectors": [
          {
              "username": "<user>",
              "password": "<password>",
              "root_certificate": "-----BEGIN CERTIFICATE-----<certificate contents>-----END CERTIFICATE-----",
              "collector_type": "VRNI_STREAMING",
              "collector_ip": "<IP>",
              "collector_port": 50000
          }
      ]
