# Download Bunny.net access logs and produce a capability frequency report.
|
||||
#
|
||||
# This is the only way to see CDN-cached request frequency — the origin
|
||||
# Prometheus metrics only see cache misses. A weekly cron run pushing the
|
||||
# output to Grafana covers >99% of analysis needs without real-time overhead.
|
||||
#
|
||||
# What this script answers:
|
||||
# - Which capabilities are queried most often (all requests, including hits)?
|
||||
# - Which device class / protocol combinations are active?
|
||||
# - What is the cache hit ratio per endpoint?
|
||||
# - Which full query string combinations are most common?
|
||||
#
|
||||
# Usage:
|
||||
# BUNNYNET_API_KEY=your-key PULL_ZONE_ID=12345 ./scripts/query-report.sh
|
||||
# BUNNYNET_API_KEY=your-key PULL_ZONE_ID=12345 DAYS=30 ./scripts/query-report.sh
|
||||
#
|
||||
# Output:
|
||||
# Human-readable report to stdout.
|
||||
# With PROMETHEUS_PUSH_URL set, also pushes counters to a Prometheus
|
||||
# Pushgateway (e.g. your dedicated analytics Grafana stack) so the weekly
|
||||
# numbers become a time-series rather than a point-in-time dump.
