Eli nqaku liza kuxubusha iprojekthi , eyakufunda iilog ze nginx, ithumele kwiClickhouse cluster. Ngesiqhelo i-ElasticSearch isetyenziswa kwiilog. I-Clickhouse ifuna izixhobo ezimbalwa (indawo yediski, i-RAM, i-CPU). Clickhouse ubhala idatha ngokukhawuleza. I-Clickhouse icinezela idatha, eyenza i-data kwidiski idibanise ngakumbi. Izibonelelo zeClickhouse zingabonwa kwiislayidi ezi-2 ezivela kwingxelo
Ukujonga ucazululo ngeelog, masenze ideshbhodi yeGrafana.
Ngubani okhathalayo, wamkelekile phantsi kwekati.
Faka nginx, grafana ngendlela eqhelekileyo.
Faka i-clickhouse cluster ene-ansible-playbook evela .
Ukwenza isiseko sedatha kunye neetafile kwiClickhouse
Kule Imibuzo yeSQL yokudala oovimba beenkcukacha kunye neetafile zenginx-log-umqokeleli kwiClickhouse zichaziwe.
Senza isicelo ngasinye ngokujika kumncedisi ngamnye weClickhouse cluster.
Inqaku elibalulekileyo. Kulo mgca, logs_cluster kufuneka endaweni yegama lakho leqela elisuka kwi clickhouse_remote_servers.xml ifayile phakathi kwe "remote_servers" kunye ne "shard".
ENGINE = Distributed('logs_cluster', 'nginx', 'access_log_shard', rand())Ukufakela kunye nokuqwalasela i-nginx-log-collector-rpm
I-Nginx-log-umqokeleli ayinayo i-rpm. Apha yenza i-rpm kuyo. rpm iya kwakhiwa kusetyenziswa
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 ulungelelwaniso /etc/nginx-log-collector/config.yaml:

Njengomenzi weseva yeHTTP esiya kuyisebenzisa ukusuka
I-nodejs-stub-server ayinayo i-rpm. Apha yenza i-rpm kuyo. rpm iya kwakhiwa kusetyenziswa
Faka iphakheji ye-nodejs-stub-server kumsinga we-nginx rpm
yum -y install yum-plugin-copr
yum copr enable antonpatsev/nodejs-stub-server
yum -y install stub_http_server
systemctl start stub_http_serverUvavanyo loxinzelelo
Uvavanyo lwenziwa kusetyenziswa i-Apache benchmark.
Yifake:
yum install -y httpd-toolsSiqala ukuvavanya sisebenzisa i-Apache benchmark ukusuka kwiiseva ezi-5 ezahlukeneyo:
while true; do ab -H "User-Agent: 1server" -c 10 -n 10 -t 10 http://vhost1/; sleep 1; done
while true; do ab -H "User-Agent: 2server" -c 10 -n 10 -t 10 http://vhost1/; sleep 1; done

while true; do ab -H "User-Agent: 5server" -c 10 -n 10 -t 10 http://vhost1/; sleep 1; doneUkumisela iGrafana
Awuyi kufumana dashboard kwiwebhusayithi esemthethweni yaseGrafana.
Ngoko ke, siya kuyenza ngesandla.
Ungafumana ideshibhodi yam egciniweyo .
Kufuneka kwakhona wenze i-table variable kunye nomxholo nginx.access_log.
I-Singlestat iyonke yezicelo:
SELECT
1 as t,
count(*) as c
FROM $table
WHERE $timeFilter GROUP BY t
Izicelo Ezingaphumelelanga ze-Singlestat:
SELECT
1 as t,
count(*) as c
FROM $table
WHERE $timeFilter AND status NOT IN (200, 201, 401) GROUP BY t
Singlestat Failing Percent:
SELECT
1 as t, (sum(status = 500 or status = 499)/sum(status = 200 or status = 201 or status = 401))*100 FROM $table
WHERE $timeFilter GROUP BY t
Singlestat Avg Ixesha lokuphendula:
SELECT
1, avg(request_time) FROM $table
WHERE $timeFilter GROUP BY 1
Ixesha leMpendulo enkulu ye-Singlestat:
SELECT
1 as t, max(request_time) as c
FROM $table
WHERE $timeFilter GROUP BY t
Bala ubume:
$columns(status, count(*) as c) from $table
Ukukhupha idatha njengepayi, kufuneka ufake i-plugin kwaye uphinde ulayishe i-grafana.
grafana-cli plugins install grafana-piechart-panel
service grafana-server restartImo yePie TOP 5:
SELECT
1, /* fake timestamp value */
status,
sum(status) AS Reqs
FROM $table
WHERE $timeFilter
GROUP BY status
ORDER BY Reqs desc
LIMIT 5
Ngapha koko ndiya kunika izicelo ngaphandle kwesikrini:
Bala i-http_arhente_yomsebenzisi:
$columns(http_user_agent, count(*) c) FROM $tableIxabiso Elilungileyo/elibi:
$rate(countIf(status = 200) AS good, countIf(status != 200) AS bad) FROM $tableixesha lempendulo:
$rate(avg(request_time) as request_time) FROM $tableIxesha lokuphendula lomlambo (ixesha lokuphendula lomlambo wokuqala):
$rate(avg(arrayElement(upstream_response_time,1)) as upstream_response_time) FROM $tableUbume boBala beTheyibhile kuzo zonke iivhosts:
$columns(status, count(*) as c) from $tableImbono jikelele yedeshbhodi
Ukuthelekisa i-avg () kunye ne-quantile ()
i-avag()
umyinge()
Isiphelo:
Ngethemba ukuba uluntu luya kubandakanyeka ekuphuhliseni / kuvavanyo kunye nokusebenzisa i-nginx-log-collector.
Kwaye xa umntu ephumeza nginx-log-umqokeleli, uya kukuxelela ukuba ugcine kangakanani idiski, RAM, CPU.
