Agenda
======

* New infra status page (https://status.documentfoundation.org , powered by cachetHQ)
+ https://redmine.documentfoundation.org/issues/1079#note-20
+ Meant to give users a quick overview (HTTP status and response time
only), not to replace the more comprehensive internal infra metrics
+ Atom & RSS feeds, email subscription
→ best not to subscribe using a TDF-hosted address!
+ 24 HTTP sites monitored at the moment; more can be added later
+ Metrics and outages are automatically filled using the cachet API and
https://github.com/CastawayLabs/cachet-monitor; scheduled maintenance can
be added too, and text/status can be edited manually to inform the
community about our progress in solving an issue
+ Current limitations:
- no v4/v6 distinction; ideally the component state would change to
“outage” if IPv6 (resp. v4) connectivity is broken, assuming there is
an AAAA (resp. A) record
- while traffic is not routed privately, DNS queries are; better to use
upstream DNS servers instead, and use gustl for .tdf only
→ solutions: use systemd-{networkd,resolved}, or a local caching
recursive resolver
- would be nice to get SMTP & IMAP status codes, too
+ TODO: add a CNAME + 301 redirect for status.libreoffice.org
+ TODO: subscribe IZBot to the feed. Can cachet push updates to it? Brett:
don't think so
+ Officially announce the page at LibOCon, but folks can subscribe already
* Prometheus alert system (Brett)
+ Merged and deployed; only email notifications for now (no SMS)
* Prometheus: downgraded node-exporter from stretch-backports to stretch on
the monitoring box
* Upgrades:
+ Question: status of tb31.libreoffice.org? (last Ubuntu — 14.04.5 LTS —
box, would like to align on our current — Debian 9.4 — baseline instead)
+ 37 boxes still on Debian Jessie (24 prod boxes incl. 3 hypervisors), need
to be updated before the end of year ideally
- some of these require more work (not based on the Jessie baseline), eg
dashboard (vm167)
- tentative plan: migrate the dashboard to vm213 (fresh Stretch VM)
during LibOCon
+ upgraded gerrit to stretch last week (got rid of salt states gerrit vs.
gerrit.prod), improved systemd unit files
* Single Sign On
+ Auth method switched from SilverStripe's own backend to SAML 2.0 on the
LibreOffice & TDF websites (SS3/newdesign)
+ Working on the migration for the blog's (WordPress) auth backend now
* Next call: Tuesday October 16 2018 at 18:30 Berlin time (16:30 UTC).
