Maqaalkani wuxuu ka hadli doonaa mashruuca , kaas oo akhrin doona nginx logs oo u diri doona kooxda Clickhouse. Caadiyan ElasticSearch waxa loo isticmaalaa loga Clickhouse wuxuu u baahan yahay ilo yar (meel bannaan oo disk ah, RAM, CPU). Clickhouse si dhakhso leh ayey u diiwaan gelisaa xogta Clickhouse waxay cufanaysaa xogta, taasoo ka dhigaysa xogta ku jirta diskka xitaa mid cufan. Faa'iidooyinka Clickhouse waxay ka muuqdaan 2 bog oo ka mid ah warbixinta
Si loo eego falanqaynta ku salaysan diiwaanka, waxaanu u samayn doonaa dashboard-ka Grafana.
Qof kasta oo danaynaya, ku soo dhawoow bisad
Ku rakib nginx, grafana habka caadiga ah.
Ku rakibida kutlada guriga iyadoo la isticmaalayo buug-ciyaareed la awoodi karo .
Abuuritaanka xogta iyo miisaska gudaha Clickhouse
Taas Su'aalaha SQL ee abuurista xog-ururinta iyo miisaska nginx-log-collector ee Clickhouse ayaa lagu sifeeyay.
Waxaan codsi kasta mid mid ugu samaynaa server kasta oo ku jira kooxda Clickhouse.
Qoraal muhiim ah. Sadarkan, logs_cluster wuxuu u baahan yahay in lagu beddelo magaca kooxdaada laga soo bilaabo faylka clickhouse_remote_servers.xml ee u dhexeeya "remote_servers" iyo "shard".

Вывод:
Waxaan rajeynayaa in bulshadu ka qayb qaadan doonto horumarinta/tijaabinta iyo adeegsiga nginx-log-collector.
Oo marka qof uu fuliyo nginx-log-collector, waxay kuu sheegi doonaan inta ay ku kaydiyeen diskka, RAM, iyo CPU.
