Verify SFM Telemetry Flow

View Collected SFM Telemetry Data using VictoriaMetrics UI (VMUI) - Cluster Mode Deployment

To view the SFM telemetry data that is streamed to VictoriaMetrics, do the following:

1. Run the following command to verify that the VictoriaMetrics pod is running:

   kubectl get pods -n telemetry -o wide | grep vm
   

2. Run the following command to verify that that all the services of VictoriaMetrics cluster are running:

   kubectl get service -n telemetry -o wide | grep vm
   

3. Note the External IP and port number of the vmselect service. The external IP and port number will be used to access the VictoriaMetrics UI (VMUI).

4. Access the VMUI in a web browser using:

   https://<external vmselect loadbalancer IP>:8481/select/0/vmui
   

5. Filter and view telemetry metrics using queries in VMUI. For example, the following query displays transceiver DOM temperature values:

transceiver_dom_temperature_value

The following are some of the key metrics that can be queried:

• transceiver_dom_temperature_value - Monitors optical transceiver temperature for hardware health

• queue_tx_pkts - Tracks transmitted packets per queue for performance monitoring

• queue_drop_pkts - Counts dropped packets per queue to identify congestion issues

• queue_tx_bits_per_second - Measures queue throughput in bits per second

• ifcounters_in_octets - Monitors incoming data volume in bytes per interface

• ifcounters_out_octets - Monitors outgoing data volume in bytes per interface

• ifcounters_in_pkts - Counts incoming packets per interface

• ifcounters_out_pkts - Counts outgoing packets per interface

• ifcounters_in_errors - Tracks input errors per interface for fault detection

• ifcounters_out_errors - Tracks output errors per interface for fault detection
