Te tuku i nga raarangi Nginx json ma te whakamahi Vector ki Clickhouse me Elasticsearch

Vector, i hangaia hei kohikohi, huri me te tuku i nga raraunga rangitaki, inenga me nga huihuinga.

→ GitHub

Ko te tuhi i roto i te reo Rust, e tohuhia ana e te mahi nui me te iti o te kohi RAM ka whakaritea ki ona analogues. I tua atu, ka nui te aro ki nga mahi e pa ana ki te tika, ina koa, te kaha ki te penapena i nga kaupapa kaore i tukuna ki te papaa i runga i te kōpae me te huri i nga konae.

Ma te hoahoanga, he pouara takahanga a Vector ka whiwhi karere mai i tetahi, neke atu ranei pūtake, ka taea te tono mo enei karere huringa, me te tuku atu ki tetahi, ki etahi atu ranei wairere.

He whakakapinga a Vector mo te filebeat me te logstash, ka taea e ia te mahi i roto i nga mahi e rua (whiwhi me te tuku i nga raarangi), etahi atu korero mo aua mea pae.

Mena i roto i te Logstash ka hangaia te mekameka hei whakaurunga → tātari → putanga ka noho ki Vector puna → hurihuri → totohu

Ka kitea nga tauira i roto i nga tuhinga.

Ko tenei tohutohu he tohutohu hou mai i Vyacheslav Rakhinsky. Kei roto i nga tohutohu taketake te tukatuka geoip. I te wa e whakamatautau ana i te geoip mai i te whatunga o roto, i puta he hapa te vector.

Aug 05 06:25:31.889 DEBUG transform{name=nginx_parse_rename_fields type=rename_fields}: vector::transforms::rename_fields: Field did not exist field=«geoip.country_name» rate_limit_secs=30

Mena ka hiahia tetahi ki te tukatuka geoip, tirohia nga tohutohu taketake mai i Vyacheslav Rakhinsky.

Ka whirihorahia e matou te huinga o Nginx (Rautaki uru) → Vector (Kaihoko | Filebeat) → Vector (Server | Logstash) → wehe i Clickhouse me te wehe i Elasticsearch. Ka whakauruhia e matou nga kaitoro e 4. Ahakoa ka taea e koe te karo me nga kaitoro e 3.

He penei te kaupapa.

Monokia a Selinux i runga i o tūmau katoa

sed -i 's/^SELINUX=.*/SELINUX=disabled/g' /etc/selinux/config
reboot

Ka whakauruhia e matou he emulator tūmau HTTP + taputapu ki runga i nga tūmau katoa

Hei emulator tūmau HTTP ka whakamahia e matou nodejs-stub-server i Maxim Ignatenko

Nodejs-stub-server karekau he rpm. ko te reira hanga rpm mo taua mea. ka hangaia te rpm ma te whakamahi Fedora Copr

Tāpirihia te antonpatsev/nodejs-stub-server

yum -y install yum-plugin-copr epel-release
yes | yum copr enable antonpatsev/nodejs-stub-server

Tāutahia te nodejs-stub-server, Apache benchmark me te mata maha i runga i nga tūmau katoa

yum -y install stub_http_server screen mc httpd-tools screen

I whakatikahia e ahau te wa whakautu stub_http_server i roto i te kōnae /var/lib/stub_http_server/stub_http_server.js kia nui ake nga raarangi.

var max_sleep = 10;

Kia whakarewahia te stub_http_server.

systemctl start stub_http_server
systemctl enable stub_http_server

Tautanga Clickhouse i runga i te tūmau 3

Ka whakamahia e ClickHouse te huinga tohutohu SSE 4.2, no reira ki te kore e tohua, ko te tautoko mo taua mea i roto i te tukatuka i whakamahia hei whakaritenga punaha taapiri. Anei te whakahau kia tirohia mena kei te tautoko te tukatuka o naianei i te SSE 4.2:

grep -q sse4_2 /proc/cpuinfo && echo "SSE 4.2 supported" || echo "SSE 4.2 not supported"

Tuatahi me hono koe i te putunga mana:

sudo yum install -y yum-utils
sudo rpm --import https://repo.clickhouse.tech/CLICKHOUSE-KEY.GPG
sudo yum-config-manager --add-repo https://repo.clickhouse.tech/rpm/stable/x86_64

Hei whakauru i nga kohinga me whakahaere e koe nga whakahau e whai ake nei:

sudo yum install -y clickhouse-server clickhouse-client

Tukua te clickhouse-server ki te whakarongo ki te kaari whatunga kei te konae /etc/clickhouse-server/config.xml

<listen_host>0.0.0.0</listen_host>

Te huri i te taumata takiuru mai i te tohu ki te patuiro

patuiro

Tautuhinga kōpeketanga paerewa:

min_compress_block_size  65536
max_compress_block_size  1048576

Hei whakahohe i te compression Zstd, i tohutohuhia kia kaua e pa ki te whirihora, engari me whakamahi DDL.

Kaore i kitea e au me pehea te whakamahi i te taapiri zstd ma te DDL i Google. Na ka waiho e ahau kia rite tonu.

Ko nga hoa mahi e whakamahi ana i te zstd compression i Clickhouse, tena koa tohaina nga tohutohu.

Hei timata i te tūmau hei daemon, whakahaere:

service clickhouse-server start

Inaianei me neke taatau ki te whakatu i te Clickhouse

Haere ki Clickhouse

clickhouse-client -h 172.26.10.109 -m

172.26.10.109 — IP o te tūmau kei te whakauruhia a Clickhouse.

Me hanga he putunga raraunga vector

CREATE DATABASE vector;

Kia tirohia kei te noho tonu te papaa raraunga.

show databases;

Waihangatia he ripanga vector.logs.

/* Это таблица где хранятся логи как есть */

CREATE TABLE vector.logs

Ka tirohia kua hangahia nga ripanga. Kia whakarewa tatou clickhouse-client me te tono.

Me haere tatou ki te patengi raraunga vector.

use vector;

Ok.

0 rows in set. Elapsed: 0.001 sec.

Kia titiro tatou ki nga tepu.

show tables;

Te whakauru i te elasticsearch i runga i te tūmau 4th ki te tuku i nga raraunga rite ki a Elasticsearch hei whakataurite ki a Clickhouse

Tāpirihia he kī rpm tūmatanui

rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch

Me hanga 2 repo:

/etc/yum.repos.d/elasticsearch.repo

Tāutahia te elasticsearch me te kibana

yum install -y kibana elasticsearch

I te mea kei roto i te kape 1, me taapiri e koe nga mea e whai ake nei ki te konae /etc/elasticsearch/elasticsearch.yml:

discovery.type: single-node

Ka taea e te vector te tuku raraunga ki te elasticsearch mai i tetahi atu tūmau, me huri tatou network.host.

network.host: 0.0.0.0

Hei hono atu ki te kibana, hurihia te tawhā server.host i te kōnae /etc/kibana/kibana.yml

server.host: "0.0.0.0"

Tawhito me te whakauru elasticsearch ki te autostart

systemctl enable elasticsearch
systemctl start elasticsearch

me te kibana

systemctl enable kibana
systemctl start kibana

Te whirihora i te Elasticsearch mo te aratau node kotahi 1 shard, 0 tauira. Ko te mea pea ka mau koe i te kahui o te maha o nga kaitoro kaore koe e hiahia ki te mahi i tenei.

Mo nga taurangi a meake nei, whakahōuhia te tauira taunoa:

curl -X PUT http://localhost:9200/_template/default -H 'Content-Type: application/json' -d '{"index_patterns": ["*"],"order": -1,"settings": {"number_of_shards": "1","number_of_replicas": "0"}}' 

tāutanga Vector hei whakakapinga mo Logstash i runga i te tūmau 2

Kaua e wareware ki te taapiri i te kaiwhakamahi vector ki te roopu e hiahiatia ana kia taea e ia te panui i nga konae rangitaki. Hei tauira, ko te nginx in centos te hanga i nga raarangi me nga mana roopu adm.

usermod -a -G adm vector

Me timata te ratonga vector

systemctl enable vector
systemctl start vector

Ka taea te tiro i nga raarangi vector penei:

journalctl -f -u vector

Me whai urunga penei i roto i nga raarangi

INFO vector::topology::builder: Healthcheck: Passed.

Whakamātautau ahotea

Ka mahia nga whakamatautau ma te whakamahi i te tohu tohu a Apache.

I tāutahia te mōkihi httpd-tools ki ngā tūmau katoa

Ka timata taatau ki te whakamatautau ma te whakamahi i te tohu tohu Apache mai i nga kaitoro rereke e 4 i te mata. Tuatahi, ka whakarewahia e matou te multixer kapeka mata, katahi ka timata taatau ki te whakamatau ma te whakamahi i te tohu tohu a Apache. Me pehea te mahi me te mata ka kitea e koe i roto Tuhinga.

Mai i te tūmau tuatahi

while true; do ab -H "User-Agent: 1server" -c 100 -n 10 -t 10 http://vhost1/; sleep 1; done

Mai i te tūmau tuatahi
