Notifiers

Overview

Post LoadDensity run summaries to Slack and Microsoft Teams over their incoming-webhook URLs. Network I/O is pluggable so tests can inject a fake poster.

Slack (Block Kit)

from je_load_density import post_slack_summary

post_slack_summary(
    webhook_url="https://hooks.slack.com/services/T000/B000/XXXX",
    title="Smoke run",
)

The payload is a Block Kit message — header + 4-field section (requests, failures, failure rate, p95 latency). post_slack_summary defaults to the current build_summary() if no summary is passed.

Teams (MessageCard)

from je_load_density import post_teams_summary

post_teams_summary(
    webhook_url="https://outlook.office.com/webhook/...",
    title="Smoke run",
)

Uses the legacy MessageCard schema (widely supported by Office 365 webhooks).

Datadog DogStatsD

from je_load_density import start_statsd_sink, stop_statsd_sink

start_statsd_sink(host="dogstatsd", port=8125, prefix="loaddensity")
# … run actions …
stop_statsd_sink()

Three packets per request: requests:1|c, request.latency:N|ms, response.size:N|h, all tagged with method / name / outcome. Pure UDP, no SDK dependency.
