I have Grafana running in docker along with Renderer. I’ve enabled screenshots in the configuration via the environment variable.
environment:
- GF_RENDERING_SERVER_URL=http://renderer:8081/render
- GF_RENDERING_CALLBACK_URL=http://grafana:3000
- GF_UNIFIED_ALERTING_SCREENSHOTS_CAPTURE=true
- GF_LOG_FILTERS=rendering:debug
I am unable to get alerts with screenshots. The alerts are linked to a dashboard and panel.
In the defaults.ini, the configuration still shows capture = false. Is it expected?
[unified_alerting.screenshots]
# Enable screenshots in notifications. You must have either installed the Grafana image rendering
# plugin, or set up Grafana to use a remote rendering service.
# For more information on configuration options, refer to [rendering].
capture = false
What else can I check to troubleshoot this issue?
