(On our Jitsi instance today: https://jitsi.documentfoundation.org/infra .)

Agenda
======

* [rdm#2463] gerrit upgraded to 2.13.11, but no OS upgrade yet, and the
highstate wasn't applied either
+ Need some refactoring of the salt states (vm148 isn't using the new
baseline)
+ Any preferred time when to do the upgrade?
+ AI guilhem: upgrade any friday/saturday night
* Prometheus
+ Brett: Which version of prometheus-node-exporter are we going to
use? monitoring.df.org is using the backports version. 0.16 was
recently uploaded into backports and changes a number of metric
names.
- G. Fair point, for the baseline we should stick to Debian proper
if possible as backports don't have security support from the
Debian Security Team
- I pulled the backport sources since I wanted prometheus 2.x, and
prometheus-node-exporter bpo came with it ^^
- Do we have reasons not to downgrade?  Unlike prometheus,
prometheus-node-exporter is (should be) in baseline
- TODO downgrade
* Alert system update
+ Brett: 'prometheus' branch ready for review, it includes some alert
rules
+ AI guilhem: review and merge
* Status page:
+ CachetHQ test instance at https://vm182.documentfoundation.org/
(snakeoil cert)
+ Works fine with MariaDB 10.1 and PHP 7.0
+ Can subscribe to events by mail or RSS/atom feeds
+ Doesn't monitor directly but another service can use the API to
send metric points and automatically change state from/to
failed/operational: https://docs.cachethq.io/v1.0/docs/addons
+ AI guilhem: Deploy a prod instance next to monitoring.tdf (Need PHP
& MariaDB)
+ monitoring.tdf is hosted at filoo, most of the prod boxes are at
manitu, so different AS:es and datacenters
* IPMI
+ new ADMIN password does seem to stick
+ iKVM is a real pain to use… would rather use the serial console
`ipmitool -I lanplus -H $IP -e'&' -U ADMIN sol activate`
+ OK to start with “console=ttyS1” in the kernel command line and
start an agetty(8) on that TTY?  Cf. berta
+ Same thing for the VMs but with ttyS0: `virsh console $vmXYZ`; we
don't really need SPICE do we?
→ OK fine to stick to the console :-)
* Hypervisor upgrades:
+ charly upgraded to 9.4 on June 30, adapted the salt config for
hypervisors accordingly
+ 9.5 released on July 14, can upgrade another hypervisor this
week-end (excelsior and/or dauntless)
- cloph: can shut down vm176 & vm177 during the upgrade
* How about moving the calls to Jitsi?  OK for everyone \o/
* Next call: Tuesday August 21 2018 at 18:30 Berlin time (16:30 UTC)
