Lesi sihloko sizoxoxa ngephrojekthi , ezofunda izingodo ze-nginx, izithumele kuqoqo le-Clickhouse. Ngokuvamile i-ElasticSearch isetshenziselwa amalogi. I-Clickhouse idinga izinsiza ezimbalwa (isikhala sediski, i-RAM, i-CPU). I-Clickhouse ibhala idatha ngokushesha. I-Clickhouse icindezela idatha, okwenza idatha ekudiski ihlangane nakakhulu. Izinzuzo zeClickhouse zingabonakala kumaslayidi angu-2 embikweni
Ukuze ubuke izibalo ngamalogi, masidale ideshibhodi ye-Grafana.
Ubani onendaba, wamukelekile ngaphansi kwekati.
Faka i-nginx, i-grafana ngendlela evamile.
Faka iqoqo le-clickhouse nge-ansible-playbook evela .
Ukudala i-database namatafula ku-Clickhouse
Kulokho Imibuzo ye-SQL yokudala imininingwane namathebula e-nginx-log-collector ku-Clickhouse ichaziwe.
Senza isicelo ngasinye ngokuvula iseva ngayinye yeqoqo le-Clickhouse.
Inothi elibalulekile. Kulo mugqa, i-logs_cluster kufanele kufakwe igama le-cluster yakho kusuka kufayela le-clickhouse_remote_servers.xml phakathi kwe-"remote_servers" kanye "ne-shard".
ENGINE = Distributed('logs_cluster', 'nginx', 'access_log_shard', rand())Ukufaka nokumisa i-nginx-log-collector-rpm
I-Nginx-log-collector ayinayo i-rpm. Lapha yenzela i-rpm. rpm izokwakhiwa kusetshenziswa
Faka iphakheji ye-rpm nginx-log-collector-rpm
yum -y install yum-plugin-copr
yum copr enable antonpatsev/nginx-log-collector-rpm
yum -y install nginx-log-collector
systemctl start nginx-log-collectorHlela ukuhlela /etc/nginx-log-collector/config.yaml:

Ukulungiselelwa kwe-nginx okujwayelekile:

Njenge-emulator yeseva ye-HTTP sizoyisebenzisa kusukela
I-nodejs-stub-server ayinayo i-rpm. Lapha yenzela i-rpm. rpm izokwakhiwa kusetshenziswa
Faka iphakheji ye-nodejs-stub-server ekukhuphukeni komfula nginx rpm
yum -y install yum-plugin-copr
yum copr enable antonpatsev/nodejs-stub-server
yum -y install stub_http_server

Ukuhlola kwenziwa kusetshenziswa ibhentshimakhi ye-Apache.
Yifake:
yum install -y httpd-toolsSiqala ukuhlola sisebenzisa ibhentshimakhi ye-Apache kusuka kumaseva ayi-5 ahlukene:

Ngeke uthole ideshibhodi kusizindalwazi esisemthethweni saseGrafana.
Ngakho-ke, sizokwenza ngesandla.
Ungathola ideshibhodi yami elondoloziwe .
Udinga futhi ukudala i-variable yetafula nokuqukethwe nginx.access_log.
Izicelo Eziphelele ze-Singlestat:

Ukuze ukhiphe idatha njengophaya, udinga ukufaka i-plugin bese ulayisha kabusha i-grafana.

Isiphetho:
Ngethemba ukuthi umphakathi uzobandakanyeka ekuthuthukiseni/ukuhlola nokusebenzisa i-nginx-log-collector.
Futhi uma othile esebenzisa i-nginx-log-collector, uzokutshela ukuthi ulondoloze kangakanani idiski, i-RAM, i-CPU.
