Vault(1.3.0) not emitting telemetry

My Vault installation(1.3.0) isn’t emitting metrics. Given below is my config stored under /etc/vault.d/telemetry.json. How I can debug the issue?

{
"telemetry": {
        "statsd_address": "127.0.0.1:8125",
        "disable_hostname": true
    }
}

Please note that I have statsd server running on localhost:8125 using Telegraf StatsD input plugin, and routing the statsd output to a file using Telegraf File output plugin, and I don’t see any telemetry data in the output. Other metrics (e.g. CPU) are showing fine.

I even tried dogstatsd_addr but didn’t work either.

Given below is Telegraf config:

[[inputs.statsd]]
protocol = "udp"
service_address = ":8125"
delete_gauges = true
delete_counters = true
delete_sets = true
delete_timings = true
percentiles = [50.0, 90.0, 99.0, 99.9, 99.95, 100.0]
metric_separator = "_"
datadog_extensions = true
allowed_pending_messages = 10000
percentile_limit = 1000


[[outputs.file]]
files = ["stdout", "/var/log/metrics.out"]
data_format = "wavefront"
