Environment

VCF Operations for Networks 9.0.0

Cause

Process was reading a stale policy file, restarting the service allows the process to read the correct policy file.

Resolution

1. Validate status of steaming service from rdb

get_policy -cid 0 -ns features -key enableNSXTStreamingMetrics

arkin> get_policy -cid 0 -ns features -key enableNSXTStreamingMetrics
Customer ID: 0
{
  "features": {
    "enableNSXTStreamingMetrics": true
  }
}

get_policy -ns features -key enableNSXTStreamingMetrics

 

arkin> get_policy -ns features -key enableNSXTStreamingMetrics
Customer ID: 10000
{
  "features": {
    "enableNSXTStreamingMetrics": true
  }
}

 

2. If enabled, restart NSX Metric Server with:
/home/ubuntu/build-target/grpc-telemetry-server/stop-grpc-nsx-metric-server.sh
