Kosmo 🏛️⚕️

25/11/08 - I named this one Kosmo as a reference to the Greek island Kos ( https://en.wikipedia.org/wiki/Kos ) because Hippocrates of Kos - https://en.wikipedia.org/wiki/Hippocrates was 'the father of medicine'. It's physically in Virginia, but the internet is also kinda cosmic 🪐.

Analytics​

Log import misc/log-analytics/import_logs.py, builds visits web-server logs with no JavaScript at all.

cron's PATH is /usr/bin:/bin, and nginx lives in /usr/sbin. So nginx -s reopen fails with "command not found" under cron while working perfectly from an interactive sudo — and it fails after the log has been moved aside. Set PATH explicitly at the top of any script cron runs. Found by using the panel's Run Now rather than waiting for the schedule to fire, which is worth doing on every new scheduled task for exactly this reason.

Import exactly once, or not at all. import_logs.py has no memory of what it has read; run it twice on one file and every visit is counted twice with no error. So the script moves the log aside, tells nginx to reopen, and waits until no process still holds the moved file before reading it — draining workers can keep a descriptor open for minutes on HTTP/2 keepalive. A fixed sleep is not enough. It also refuses outright if the log contains anything outside its intended scope, so a broken config stops the import instead of importing the wrong data.

notes​

  • MultiSites.getAll omits a site with no archived data for the period — absent, not zero. Both conditions matter: a site that exists but has no visits is missing, and a site with live visits is still missing until the next archive run. Live.getCounters reads the raw tables, so the pair distinguishes "not archived yet" from "not tracking".

  • Excluded IPs are global as well as per-site, on separate admin screens. Clearing a per-site list does nothing if the address is in the global one — which presents as "tracking is broken" when it is working exactly as configured. Exclusion matches the full IP before anonymisation, so IP masking does not break it.

  • Today's archive is considered fresh for 900s. Re-archiving inside that window is skipped and reports look stale. Scheduling the import ten minutes before the archive cron avoids ever meeting this.

  • A new site's default report date is yesterday, so day one looks empty until you move the date picker.
