Minutes

• Icinga Alerts (Crwilliams)
  • SUSU / MEM (Leth)
    • Is it possible to upgrade syslog-ng?
    • morse/Davetaz happy for Leth to do this
    • Actually don't upgrade because libc needs upgrading that will require all binaries to be updated which is really not a good idea.
  • SUSU / Disk /tmp/ (Leth)
    • commit-log has been cleared after copy made to auth
  • AUTH/AUTH
    • Not sure what is failing yet
  • AUTH/EAPOL-EDUROAM
    • We need to add checks over PEAP that will be provided by mike
    • Need to investigate how many protocols are actually supported by eduroam
  • All Homenode tunnels outage - OpenVPN (SSL) (Davetaz/daveruss)
    • Updating openvpn package broke all the tunnels
    • Problem caused by temporary client config files not been able to write to disk because of permissions
    • We were using a debug flag that we shouldn't be using
    • Reduced run level of OpenVPN from 3 to 2
    • Specified temp directory as /tmp so that openvpn can write to disk as nobody
    • Andrew_W said we need to update our wiki pages on OpenVPN top reflect these customisations
  • MONITOR/DISK / - Database issues?
    • Leth setup manual logrotate of syslog-ng
  • AUTH/DISK / - Database issues?
    • Davetaz moved all the mysql binary logs to the /home partition in /home/large_directories/
    • We need to change the config for mysql so that it doesn't make binary logs as we don't need them
    • Look at the mysql logging and see if we can find a way of tidying this up on the nightly backups
  • GW/DISK /
    • Leth probably gzipped some stuff
    • Some log files could probably be cleared out
    • Nagios was running on GW, just logging itself without telling anyone. This has been stopped but needs to be removed and its log files cleared up
  • 32/3089-UPS - remove from Icinga?
    • Davetaz happy for this to be removed
    • Reporting will be made directly to email and irc
    • crwilliams reckons we should log the data in icinga but not monitor or warn
  • MONITOR/DEBSUMS
    • Timing out so timeout increased.
    • Taking too long, needs to be investigated.
  • MONITOR/check_nsca* (Leth)
    • Has been flapping. Leth has now fixed both of these.
  • PACKAGE warnings not reported in the channel
    • crwilliams is not sure why this is happening.

• Cron emails (Leth)
  • Forwarding - Not enabled on GW. Other servers?
    • Davetaz will add the relay config for mail on the other servers as he has got the config sitting around
