Remote write queue size not increasing

Exporters and Metrics
1

Hey I’m trying to explore methods to prevent data loss when the endpoint is down so i’m using remote_write_queue with prometheus remote write exporter in opentelemetry in gateway mode on a Virtual Machine. My endpoint is a Victoria Metrics database on a LKE cluster.

Config used:

.
.
.
processors:
  batch:
    send_batch_size: 10
    timeout: 5s
    send_batch_max_size: 15
  memory_limiter:
    check_interval: 1s
    limit_percentage: 90
    spike_limit_percentage: 16

exporters:
  logging:
    verbosity: normal
  prometheusremotewrite/1:
    endpoint: "http://victoriametrics.com/insert/0/prometheus/"
    remote_write_queue:
      enabled: true
      num_consumers: 2
      queue_size: 20
service:
  pipelines:
    metrics/1:
      receivers: [otlp, prometheus,hostmetrics] 
      processors: [batch,memory_limiter,metricstransform]
      exporters: [logging,prometheusremotewrite/1]

These are the set of processors and exporters that i am using. When the Victoria Metrics endpoint is down, the queue size should increase right? However, I haven’t seen any increase in the queue size.

Please let me know under what cases or config will I be able to see the remote write queue size increase.

Thank you
