NPM's access log only describes hosts somebody visited; the host most likely to be quietly broken is the one nobody does. Probes carry a User-Agent npm_access_stats.sh drops — unmarked, this monitor would be fifty thousand requests a day in the very logs it reports on.

# PURPOSE
|
|
# ─────────────────────────────────────────────────────────────────────────────
|
|
# Probes every hostname NPM serves, from outside the proxy, once per run. Produces the uptime
|
|
# percentages and history strip on the Proxies tab, and the wobble list for the Sunday report.
|
|
#
|
|
# NPM's access log only describes hosts somebody visited. The host most likely to be quietly
|
|
# broken is the one nobody visited, and nothing was watching those at all.

# ==============================================================================================
|
|
# OPERATIONAL MODEL
|
|
# ==============================================================================================
|
|
#
|
|
# A wrapper. The work is in uptime_probe.php, which issues all probes in parallel through
|
|
# curl_multi so one pass costs about as long as the slowest domain rather than the sum.
|
|
#
|
|
# Runs every minute, injected by include/scheduler.php alongside the other background writers.
|
|
# Nothing about the storage assumes that cadence — everything is counts and time buckets.
|
|
#
|
|
# Probes carry the User-Agent Varaverk-Uptime/1.0, which npm_access_stats.sh excludes. Without
|
|
# that, this monitor becomes fifty thousand requests a day in the logs it reports on.
