DuckCorp Infrastructure: work

Added by Marc Dequènes about 4 years ago

  • [recently] Zabbix:
    • created a proxy on ELwing to unload Daneel a bit (will be necessary when the server is put outside in the future anyway)
    • tweaked settings a bit and tried to reduce load on Daneel
    • moved extra MIBs in a more proper location (impact because the SMI setting was not enough and the SNMP had to be adapted too)
  • Elwing:
    • worked on having local services use the main IP and not the ppp IP (impact on Zabbix)
    • firewall: protected the Zabbix trapper from outside, as Zabbix does not implement any auth
  • MariaDB: increased partition size a bit (we should check if the recent increase is legitimate)

DuckCorp Infrastructure: work

Added by Marc Dequènes about 4 years ago

  • Zabbix:
    • HistoryCacheSize 8MB->32MB (necessary after adding more items)
    • forced HK global retention to ease its work: 3d history (most were 7d, very high amount of data) and 3y trends (most were 1y, very reasonable amount of data)
    • increased DB partition 15GB->30GB
  • Monit: removed everywhere
  • Toushirou: removed quota tools (unused)
  • MariaDB: fixed systemd state (after recent migration from MySQL)
  • dico.dc.o:
    • Memcached: stop trying to use HugePages, as it now fails to start with systemd
    • Dicod: dictd symlink was ignored by systemd and dicod was disabled, then enabled and started
