Using Grafana
Navigating Dashboards
- Open metrics.o.webex.com.
- Select the WxCDI folder and the relevant device/service dashboard.
- Set a time range that includes the symptom and a known-good period before it.
- Filter from region → customer/tenant → cluster → device where those variables exist.
- Check the latest sample timestamp and compare a healthy peer.
Reading Alerts
| State | Meaning |
|---|---|
| Normal | The query condition is not currently met; still confirm data freshness |
| Pending | The condition is met but the configured pending period has not elapsed |
| Alerting | The condition and duration are met |
| No Data | The query returned no series; investigate loss of visibility |
| Error | Rule evaluation failed; validate service health independently |
Creating Panels
Use Explore first. Confirm the metric and labels across representative regions, then add the panel to an approved dashboard. Define units, legend, time range, no-data behavior, ownership, and source-control location.
Useful PromQL Queries
up{job=~".*<device_or_service>.*"}
min_over_time(up{job=~".*<device_or_service>.*"}[15m]) == 0
Inspect actual label values before adding customer, region, or device filters.
Tips & Tricks
- Avoid “Last 30 days” for first-response queries; start narrow and expand.
- A green panel with old data is not healthy evidence.
- Use dashboard/search links with the time range and filters in incident handoffs.
- Do not overwrite shared dashboards with temporary investigation panels.
