Varnish Cache Monitoring
Optional: Enable cache hit ratio and backend health metrics
If you have Varnish Cache installed, the agent can automatically monitor cache performance. To enable Varnish monitoring, the agent user needs read access to Varnish's shared memory file (used by varnishstat).
# Add the agent user to the varnish group
sudo usermod -aG varnish nginx
# Restart the agent to apply permissions
sudo systemctl restart amplify-agent
Why is this needed? The Varnish shared memory file (/var/lib/varnish/*/_.vsm) is readable by the varnish group. Adding the agent user to this group allows it to read statistics without elevated privileges.
