Zabbix server tweaks #240

Closed davidelang closed 8 months ago

davidelang commented 5 years ago

things we needed to do for performance

increase postgesql max connections and shared buffers as per https://stackoverflow.com/questions/30778015/how-to-increase-the-max-connections-in-postgres

adjust poller numbers per https://blog.zabbix.com/monitoring-how-busy-zabbix-processes-are/457/

lots of template tweaks

set auto-registration actions

Linux (including OpenWRT) systems can auto-register themselves, routers and switches need to be manually added. the zabbix_agentd.conf should have a metadata tag that says what type of system it is (AP, server, sign, self-reg, etc

we installed the lldp module from https://share.zabbix.com/network_devices/l2-discovery-module-for-lldp there does not seem to be a practical difference between the two templates (we need to look at that more)

in 17x we did not setup users or security.

openwrt agent config: https://github.com/socallinuxexpo/scale-network/blob/master/openwrt/files/etc/zabbix_agentd.conf

ansible agent config mirrors the openwrt and correctly sets HostMetadata: https://github.com/socallinuxexpo/scale-network/blob/master/ansible/roles/zabbixagent/templates/zabbix_agentd.conf.j2

Closing this since we are moving away from Zabbix.
