Uptime Checks That Page Someone When More Than One Probe Fails
Application Insights Standard tests with the metric alert that makes them tell somebody. Microsoft says a test without an alert rule only notifies the portal, recommends five locations and alerting at locations minus two, and retires URL ping tests on 30 September 2026. The module follows all three, checks certificate lifetime, and lets content, not only a 200, decide what up means.

Documentation
azure-uptime-check
Uptime checks with alerts on Azure Application Insights. Works with Terraform and OpenTofu
(>= 1.6), azurerm provider >= 4.0, < 5.0.
A test without an alert rule tells nobody. Microsoft's guide: without an alert rule and action groups you only get in-portal notifications. The module creates an alert per check and refuses one with no action group unless accept_portal_only_alerts is set.
One location failing is not an outage. Microsoft recommends at least five locations and alerting at locations minus two; that is the default.
URL ping tests are gone: Microsoft retires them on 30 September 2026. These are Standard tests, which also check the TLS certificate and its remaining lifetime.
A healthy page is not always a 200. expected_status and content_match decide what up means.
Header values are plain text in the plan and state; point checks at an endpoint that needs no credentials.
Verification
Static validation runs tofu fmt, init, validate, tflint and checkov.
This module has not yet had a live test, so it is published as statically
validated with its live test pending and does not carry the live-tested mark.

azure-grafana
API keys are long-lived, unscoped bearer tokens that read every dashboard and end up in CI variables; the login page is public by default; and the Essential SKU is a single instance with no SLA. Keys off, login over a private endpoint, Standard SKU zone-redundant, fixed outbound addresses for data-source allow lists, and the identity it reads with exported for its Monitoring Reader grant.
azure-sentinel
retention_in_days defaults to 30, against intrusions usually discovered months later - so the first question, when did this start, gets silence rather than an answer. daily_quota_gb is a trap both ways and has no safe default, so the module makes you choose. And onboarding Sentinel connects no data source at all.
azure-monitor-baseline
Central Log Analytics workspace, diagnostic-settings-everywhere pattern, action groups and starter alert pack (metric + log + activity).
azure-flow-logs
enabled = false creates a flow log that logs nothing; a retention policy that is off keeps the JSON blobs until somebody deletes the storage account; and without Traffic Analytics nobody ever opens them. Every target is created enabled, retention defaults to 90 days, and Traffic Analytics is on whenever a workspace is given - raw blobs with no aggregation have to be asked for.
azure-application-insights
When the daily cap is hit everything after it is discarded until midnight and the dashboard goes flat, and the one email that says so has its own switch. Ingestion sampling stacks on the SDK's sampling and the metrics rescale. Both are refused without being named, and availability tests are created with the alerts that make an outage reach a person rather than a chart.
azure-activity-log
The subscription's Activity Log exported to a Log Analytics workspace, a storage account and/or an Event Hub, because Azure keeps it for ninety days and then forgets. All eight categories go; dropping Administrative, Security or Policy, the three an investigation asks for, is accepted by name. The workspace's retention is the workspace's setting; the years live in the storage account.
