Datadog: Time Trend metric reporting as Gauge with no units

Grafana k6 OSS Support
1

I have a custom Trend metric with time, for example:

export let request_latency = new Trend("request_latency", true);

which reports in the k6 summary report as:

request_latency.....: avg=163.13ms min=136ms    med=140ms    max=482ms    p(90)=144ms    p(95)=245.39ms

When it is reported to Datadog, it is reported as a Guage with no time units in the metadata:

If it were just one of these Trends it would be easy to edit the metrics in Datadog from the screen above and add milliseconds as the unit. However, I have many of these metrics and to retroactively go through and add time units would be a huge pain.

Any suggestions would be greatly appreciated!

Additional Info:

K6 v0.36
Datadog Agent running with:

docker run -d \
    --name datadog \
    -v /var/run/docker.sock:/var/run/docker.sock:ro \
    -v /proc/:/host/proc/:ro \
    -v /sys/fs/cgroup/:/host/sys/fs/cgroup:ro \
    -e DD_SITE="datadoghq.com" \
    -e DD_API_KEY=<> \
    -e DD_DOGSTATSD_NON_LOCAL_TRAFFIC=1 \
    -p 8125:8125/udp \

FWIW, I’m aware of the the summaryTimeUnit option, but K6 is already labelling the units correctly in the summary for that metric

export const options = {
  summaryTimeUnit: 'ms',
};
