Logaí Nginx json a sheoladh ag baint úsáide as Vector go Clickhouse agus Elasticsearch

veicteoir, atá deartha chun sonraí loga, méadracht agus imeachtaí a bhailiú, a athrú agus a sheoladh.

→ Github

Agus é scríofa sa teanga Rust, is sainairíonna é ardfheidhmíocht agus tomhaltas íseal RAM i gcomparáid lena analógacha. Ina theannta sin, tugtar aird mhór ar fheidhmeanna a bhaineann le cirte, go háirithe, an cumas imeachtaí neamhsheolta a shábháil ar mhaolán ar dhiosca agus comhaid a rothlú.

Go ailtireachta, is ródaire imeachta é Vector a fhaigheann teachtaireachtaí ó cheann amháin nó níos mó foinsí, ag cur i bhfeidhm go roghnach thar na teachtaireachtaí seo claochluithe, agus iad a chur chuig ceann amháin nó níos mó draenacha.

Is ionadach é veicteoir do bhuille comhaid agus logstash, is féidir leis gníomhú sa dá ról (logs a fháil agus a sheoladh), tuilleadh sonraí orthu Líne.

Más i Logstash a thógtar an slabhra mar ionchur → scagaire → aschur ansin i Veicteoir atá sé foinsí → transforms → doirtil

Tá samplaí le fáil sna doiciméid.

Is treoir athbhreithnithe é an treoir seo ó Vyacheslav Rakhinsky. Tá próiseáil geoip sna treoracha bunaidh. Agus geoip á thástáil ó líonra inmheánach, thug veicteoir earráid.

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

Más gá do dhuine ar bith geoip a phróiseáil, déan tagairt ansin do na treoracha bunaidh ó Vyacheslav Rakhinsky.

Déanfaimid an meascán de Nginx (logs Rochtana) a chumrú → Veicteoir (Cliant | Filebeat) → Vector (Freastalaí | Logstash) → ar leithligh i Clickhouse agus ar leithligh i Elasticsearch. Déanfaimid 4 fhreastalaí a shuiteáil. Cé gur féidir leat é a sheachbhóthar le 3 freastalaithe.

Tá an scéim rud éigin mar seo.

Díchumasaigh Selinux ar do fhreastalaithe go léir

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

Suiteáilimid aithriseoir freastalaí HTTP + fóntais ar gach freastalaí

Mar aithriseoir freastalaí HTTP úsáidfimid nódejs-stub-freastalaí ó Maxim Ignatenko

Níl rpm ag Nodejs-stub-server. Anseo cruthaigh rpm dó. rpm a thiomsú ag baint úsáide as Fedora Copr

Cuir leis an stór antonpatsev/nodejs-stub-server

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

Suiteáil nodejs-stub-server, tagarmharcáil Apache agus ilphléacsálaí teirminéil scáileáin ar gach freastalaí

yum -y install stub_http_server screen mc httpd-tools screen

Ceartaigh mé an t-am freagartha stub_http_server sa chomhad /var/lib/stub_http_server/stub_http_server.js ionas go raibh níos mó logaí ann.

var max_sleep = 10;

Seolfaimid stub_http_server.

systemctl start stub_http_server
systemctl enable stub_http_server

Suiteáil Clickhouse ar fhreastalaí 3

Úsáideann ClickHouse an tacar treoracha SSE 4.2, mar sin mura sonraítear a mhalairt, beidh tacaíocht dó sa phróiseálaí a úsáidtear ina riachtanas córais breise. Seo é an t-ordú le seiceáil an dtacaíonn an próiseálaí reatha le SSE 4.2:

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

Ar dtús ní mór duit an stór oifigiúil a nascadh:

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

Chun pacáistí a shuiteáil ní mór duit na horduithe seo a leanas a rith:

sudo yum install -y clickhouse-server clickhouse-client

Lig do clickhouse-server éisteacht leis an gcárta líonra sa chomhad /etc/clickhouse-server/config.xml

<listen_host>0.0.0.0</listen_host>

An leibhéal logála a athrú ó rian go dífhabhtú

dífhabhtaigh

Socruithe caighdeánacha comhbhrú:

min_compress_block_size  65536
max_compress_block_size  1048576

Chun comhbhrú Zstd a ghníomhachtú, moladh gan teagmháil a dhéanamh leis an gcumraíocht, ach DDL a úsáid.

Níorbh fhéidir liom a fháil amach conas comhbhrú zstd a úsáid trí DDL in Google. Mar sin d'fhág mé é mar atá.

Comhghleacaithe a úsáideann comhbhrú zstd i Clickhouse, roinn na treoracha le do thoil.

Chun an freastalaí a thosú mar dheamhan, rith:

service clickhouse-server start

Anois, a ligean ar bogadh ar aghaidh go dtí a bhunú Clickhouse

Téigh go dtí Clickhouse

clickhouse-client -h 172.26.10.109 -m

172.26.10.109 - IP an fhreastalaí ina bhfuil Clickhouse suiteáilte.

Déanaimis bunachar sonraí veicteoir a chruthú

Suiteáil elasticsearch ar an 4ú freastalaí chun na sonraí céanna a sheoladh chuig Elasticsearch chun comparáid a dhéanamh le Clickhouse

Cuir eochair phoiblí rpm leis

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

Cruthaimis 2 repo:

Suiteáil elasticsearch agus kibana

yum install -y kibana elasticsearch

Ós rud é go mbeidh sé i gcóip amháin, ní mór duit an méid seo a leanas a chur leis an gcomhad /etc/elasticsearch/elasticsearch.yml:

discovery.type: single-node

Ionas gur féidir le veicteoir sonraí a sheoladh chuig elasticsearch ó fhreastalaí eile, déanaimis network.host a athrú.

network.host: 0.0.0.0

Chun nascadh le kibana, athraigh an paraiméadar server.host sa chomhad /etc/kibana/kibana.yml

server.host: "0.0.0.0"

Sean agus áirítear elasticsearch i autostart

systemctl enable elasticsearch
systemctl start elasticsearch

agus kibana

systemctl enable kibana
systemctl start kibana

Elasticsearch á chumrú do mhód aon-nóid 1 shard, 0 macasamhail. Is dócha go mbeidh braisle agat de líon mór freastalaithe agus ní gá duit é seo a dhéanamh.

Le haghaidh innéacsanna amach anseo, nuashonraigh an teimpléad réamhshocraithe:

Agus an athsholáthar Filebeat a chumrú sa chumraíocht /etc/vector/vector.toml. Is é seoladh IP 172.26.10.108 seoladh IP an fhreastalaí loga (Vector-Server)

Ná déan dearmad an veicteoir úsáideora a chur leis an ngrúpa cuí ionas gur féidir leis comhaid loga a léamh. Mar shampla, nginx i centos cruthaíonn sé logaí le cearta grúpa riarthóra.

usermod -a -G adm vector

Cuirimis tús leis an tseirbhís veicteora

systemctl enable vector
systemctl start vector

Is féidir logaí veicteoirí a fheiceáil mar seo:

journalctl -f -u vector

Ba chóir go mbeadh iontráil mar seo sna logaí

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

Tástáil Strus

Déanaimid tástáil ag baint úsáide as tagarmharcáil Apache.

Suiteáladh an pacáiste httpd-tools ar gach freastalaí

Cuirimid tús le tástáil ag baint úsáide as tagarmharcáil Apache ó 4 fhreastalaithe éagsúla ar an scáileán. Ar dtús, seolann muid an t-ilphléacsóir críochfoirt scáileáin, agus ansin cuirimid tús le tástáil ag baint úsáide as tagarmharc Apache. Conas a bheith ag obair le scáileán is féidir leat a Airteagal.

Ón 1ú freastalaí

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

Ón 2ú freastalaí

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

Ón 3ú freastalaí

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

Ón 4ú freastalaí

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

Is é 857.19 MB méid tábla na logaí.

Is é méid na sonraí céanna san innéacs in Elasticsearch ná 4,5GB.

Mura sonraíonn tú sonraí sa veicteoir sna paraiméadair, glacann Clickhouse 4500/857.19 = 5.24 uair níos lú ná i Elasticsearch.

I veicteoir, úsáidtear an réimse comhbhrú de réir réamhshocraithe.
