Application — Home
Tab label: Home — Default time range: Last 7 days
The Home page is the landing tab of the MS Teams Observability app. It provides a high-level summary of your Teams calling activity — use it as a daily health check before diving into details on other pages.
The time range is adjustable via the Grafana time picker (top right). All KPIs and charts recompute when the range changes.
KPI Cards
Section titled “KPI Cards”Three key performance indicators at the top of the page:
| KPI | Description | Interpretation |
|---|---|---|
| Total Calls | Number of MS Teams calls in the selected time range | Compare day-over-day. A sudden drop may indicate collection issues. |
| Healthy Calls % | Percentage of calls classified as Good (all streams within quality thresholds) | Above 95%: excellent. 80-95%: acceptable. Below 80%: investigate on Sites or Calls. |
| Unique Callers | Number of distinct users who made or received calls | Watch for trends — declining callers may indicate user adoption issues. |
Charts
Section titled “Charts”Call Health Distribution
Section titled “Call Health Distribution”A stacked bar or donut chart showing the proportion of Good, Poor, and Unclassified calls.
| Segment | Color | Meaning |
|---|---|---|
| Good | Green | All streams within quality thresholds |
| Poor | Red | At least one stream exceeded a quality threshold |
| Unclassified | Grey | Insufficient telemetry data to classify |
Use this chart to spot quality degradation at a glance over time.
