Ukuthumela izingodo ze-Nginx json kusetshenziswa i-Vector ku-Clickhouse ne-Elasticsearch

Vector, eklanyelwe ukuqoqa, ukuguqula nokuthumela idatha yelogi, amamethrikhi nemicimbi.

→ I-Github

Njengoba ibhalwe ngolimi lwe-Rust, ibonakala ngokusebenza okuphezulu nokusetshenziswa okuphansi kwe-RAM uma kuqhathaniswa nama-analogues ayo. Ngaphezu kwalokho, kunakekelwa kakhulu imisebenzi ehlobene nokunemba, ikakhulukazi, amandla okugcina imicimbi engathunyelwanga ku-buffer kudiski futhi ujikeleze amafayela.

Ngokwezakhiwo, iVector iyirutha yomcimbi eyamukela imilayezo evela koyedwa noma ngaphezulu imithombo, ngokuzikhethela usebenzisa le milayezo izinguquko, futhi uzithumele koyedwa noma ngaphezulu amapayipi amanzi.

I-Vector ithatha indawo ye-filebeat ne-logstash, ingasebenza kuzo zombili izindima (yamukele futhi ithumele izingodo), imininingwane eyengeziwe kuzo. isayithi.

Uma ku-Logstash iketango lakhiwe njengokufakwayo → isihlungi → okukhiphayo bese kuba kuVector imithombo → uyashintsha → uyacwila

Izibonelo zingatholakala emibhalweni.

Lo myalelo uwumyalelo obuyekeziwe ovela Vyacheslav Rakhinsky. Imiyalo yoqobo iqukethe ukucutshungulwa kwe-geoip. Lapho ihlola i-geoip kunethiwekhi yangaphakathi, i-vector inikeze iphutha.

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

Uma noma ubani edinga ukucubungula i-geoip, bheka iziqondiso zoqobo ezivela Vyacheslav Rakhinsky.

Sizomisa inhlanganisela ye-Nginx (Finyelela amalogi) → Vector (Client | Filebeat) → Vector (Server | Logstash) → ngokuhlukile ku-Clickhouse futhi ngokuhlukene ku-Elasticsearch. Sizofaka amaseva angu-4. Nakuba ungakwazi ukuyidlula ngamaseva ama-3.

Uhlelo lufana nalokhu.

Khubaza i-Selinux kuwo wonke amaseva akho

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

Sifaka i-emulator yeseva ye-HTTP + izinsiza kuwo wonke amaseva

Njenge-emulator yeseva ye-HTTP sizoyisebenzisa nodejs-stub-server kusukela UMaxim Ignatenko

I-Nodejs-stub-server ayinayo i-rpm. kuyinto yenzela i-rpm. rpm izokwakhiwa kusetshenziswa Fedora Copr

Engeza i-antonpatsev/nodejs-stub-server repository

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

Faka i-nodejs-stub-server, i-Apache benchmark kanye ne-screen multiplexer kuwo wonke amaseva

yum -y install stub_http_server screen mc httpd-tools screen

Ngilungise isikhathi sokuphendula se-stub_http_server kufayela le-/var/lib/stub_http_server/stub_http_server.js ukuze kube namalogi amaningi.

var max_sleep = 10;

Masiqalise i-stub_http_server.

systemctl start stub_http_server
systemctl enable stub_http_server

Ukufakwa kwe-Clickhouse kuseva 3

I-ClickHouse isebenzisa isethi yemiyalo ye-SSE 4.2, ngakho-ke ngaphandle kokuthi kucaciswe ngenye indlela, ukusekelwa kwayo kuphrosesa esetshenzisiwe kuba imfuneko yohlelo eyengeziwe. Nawu umyalo wokuhlola ukuthi iphrosesa yamanje iyayisekela yini i-SSE 4.2:

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

Okokuqala udinga ukuxhuma inqolobane esemthethweni:

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

Ukufaka amaphakheji udinga ukusebenzisa imiyalo elandelayo:

sudo yum install -y clickhouse-server clickhouse-client

Vumela i-clickhouse-server ukuthi ilalele ikhadi lenethiwekhi efayeleni /etc/clickhouse-server/config.xml

<listen_host>0.0.0.0</listen_host>

Ukushintsha izinga lokungena kusuka ekulandeleni kuya ekulungiseni iphutha

lungisa

Izilungiselelo zokucindezelwa okujwayelekile:

min_compress_block_size  65536
max_compress_block_size  1048576

Ukuze wenze kusebenze ukucindezelwa kwe-Zstd, kwelulekwe ukuthi ungathinti ukulungiselelwa, kodwa usebenzise i-DDL.

Angikwazanga ukuthola indlela yokusebenzisa ukucindezela kwe-zstd nge-DDL ku-Google. Ngakho ngayishiya injalo.

Ozakwethu abasebenzisa ukucindezela kwe-zstd ku-Clickhouse, sicela wabelane ngeziyalezo.

Ukuze uqale iseva njenge-daemon, sebenzisa:

service clickhouse-server start

Manje ake siqhubekele phambili ekusetheni i-Clickhouse

Iya ku-Clickhouse

clickhouse-client -h 172.26.10.109 -m

172.26.10.109 — IP yeseva lapho iClickhouse ifakwe khona.

Ake sakhe isizindalwazi se-vector

Ukufaka i-elasticsearch kuseva yesi-4 ukuthumela idatha efanayo ku-Elasticsearch ukuze iqhathaniswe ne-Clickhouse

Engeza ukhiye we-rpm osesidlangalaleni

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

Masidale ama-repo angu-2:

autorefresh=1
type=rpm-md

Faka i-elasticsearch ne-kibana

yum install -y kibana elasticsearch

Njengoba izoba kukhophi engu-1, udinga ukwengeza okulandelayo kufayela /etc/elasticsearch/elasticsearch.yml:

discovery.type: single-node

Ukuze leyo vector ikwazi ukuthumela idatha ku-elasticsearch kwenye iseva, ake sishintshe network.host.

network.host: 0.0.0.0

Ukuze uxhume ku-kibana, shintsha ipharamitha ye-server.host efayeleni /etc/kibana/kibana.yml

server.host: "0.0.0.0"

Okudala futhi kufaka phakathi i-elasticsearch ku-autostart

systemctl enable elasticsearch
systemctl start elasticsearch

futhi kibana

systemctl enable kibana
systemctl start kibana

Ilungiselela i-Elasticsearch yemodi yenodi eyodwa shard engu-1, i-replica engu-0. Kungenzeka ukuthi uzoba neqoqo lenombolo enkulu yamaseva futhi awudingi ukwenza lokhu.

Ukuze uthole izinkomba zesikhathi esizayo, buyekeza isifanekiso esizenzakalelayo:

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"}}'

Futhi ulungiselele ukushintshwa kwe-Filebeat ku-config /etc/vector/vector.toml. Ikheli lasesizindeni se-inthanethi 172.26.10.108 ikheli lasesizindeni se-inthanethi leseva yelogi (Vector-Server)

data_dir = "/var/lib/vector"

[sources.nginx_file]
  type                          = "file"
  include                       = [ "/var/log/nginx/access.json.log" ]
  start_at_beginning            = false
  fingerprinting.strategy       = "device_and_inode"

[sinks.nginx_output_vector]
  type                          = "vector"
  inputs                        = [ "nginx_file" ]

  address                       = "172.26.10.108:9876"

Ungakhohlwa ukwengeza umsebenzisi we-vector eqenjini elidingekayo ukuze akwazi ukufunda amafayela okungena. Isibonelo, i-nginx ku-centos idala amalogi anamalungelo eqembu le-adm.

usermod -a -G adm vector

Ake siqale isevisi ye-vector

systemctl enable vector
systemctl start vector

Amalogi weVector angabukwa kanje:

journalctl -f -u vector

Kufanele kube khona okufakiwe okufana nalokhu kulogi

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

Ukuhlolwa Kwengcindezi

Ukuhlola kwenziwa kusetshenziswa ibhentshimakhi ye-Apache.

Iphakheji yamathuluzi we-httpd ifakwe kuwo wonke amaseva

Siqala ukuhlola sisebenzisa ibhentshimakhi ye-Apache kusuka kumaseva angu-4 ahlukene esikrinini. Okokuqala, sethula i-multiplexer yetheminali yesikrini, bese siqala ukuhlola sisebenzisa ibhentshimakhi ye-Apache. Indlela yokusebenza ngesikrini ongayithola isihloko.

Kusuka kuseva yoku-1

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

Kusuka kuseva yoku-2

while true; do ab -H "User-Agent: 2server" -c 100 -n 10 -t 10 http://vhost2/; sleep 1; done

Kusuka kuseva yoku-3

while true; do ab -H "User-Agent: 3server" -c 100 -n 10 -t 10 http://vhost3/; sleep 1; done

Kusuka kuseva yoku-4

while true; do ab -H "User-Agent: 4server" -c 100 -n 10 -t 10 http://vhost4/; sleep 1; done

Ake sihlole idatha ku-Clickhouse

Iya ku-Clickhouse

Ake sithole ukuthi zingakanani izingodo ezithathwe eClickhouse.

Usayizi wetafula lamalogi ngu-857.19 MB.

Usayizi wedatha efanayo kunkomba ku-Elasticsearch ngu-4,5GB.

Uma ungayicacisi idatha ku-vector kumapharamitha, i-Clickhouse ithatha 4500/857.19 = izikhathi ezingaphansi kuka-5.24 kune-Elasticsearch.

Ku-vector, inkambu yokucindezela isetshenziswa ngokuzenzakalelayo.
