O lenei tusiga o le a talanoaina le poloketi , lea o le a faitau ogalaau nginx, auina atu i latou i le Clickhouse cluster. E masani ona fa'aoga ElasticSearch mo ogalaau. Clickhouse e manaʻomia le itiiti ifo o punaoa (vaavaʻa vaʻa, RAM, PPU). O le Clickhouse e tusia faʻamatalaga vave. O le Clickhouse e faʻapipiʻi faʻamaumauga, lea e faʻapipiʻi atili ai faʻamaumauga i luga o le disk. Fa'amanuiaga ole Clickhouse e mafai ona va'aia ile 2 fa'ata'ita'iga mai le lipoti
Ina ia va'ai au'ili'iliga e ala i ogalaau, se'i o tatou faia se dashboard mo Grafana.
O ai e popole, fa'afeiloa'i i lalo o pusi.
Faʻapipiʻi nginx, grafana i le auala masani.
Fa'apipi'i le kulupu clickhouse ma le ansible-playbook mai .
Fausia se faʻamaumauga ma laulau ile Clickhouse
I lena O fesili SQL mo le fatuina o faʻamaumauga ma laulau mo nginx-log-collector i Clickhouse o loʻo faʻamatalaina.
Matou te faia talosaga taʻitasi i luga o sapalai taʻitasi o le Clickhouse cluster.
Fa'amatalaga taua. I lenei laina, e tatau ona sui le logs_cluster i lou igoa fuifui mai le faila clickhouse_remote_servers.xml i le va o le "remote_servers" ma le "shard".
