Tuuina atu Nginx json ogalaau e faʻaaoga ai le Vector ile Clickhouse ma Elasticsearch

Veʻa, fuafuaina e aoina, suia ma auina atu faʻamaumauga faʻamaumauga, metrics ma mea tutupu.

O le tusia i le gagana Rust, o loʻo faʻaalia i le maualuga o le faʻatinoga ma le maualalo o le RAM faʻatusatusa i ana analog. E le gata i lea, e tele le gauai e totogi i galuega e fesoʻotaʻi ma le saʻo, aemaise lava, le mafai ona faʻasaoina mea e leʻi tuʻuina atu i se paʻu i luga o le disk ma sui faila.

Faʻataʻitaʻiga, Vector o se mea e fai ai le router e maua mai feʻau mai le tasi pe sili atu punavai, e fa'atatau ile fa'aoga i luga o nei fe'au suiga, ma auina atu i se tasi pe sili atu alavai.

Vector o se sui mo le filebeat ma logstash, e mafai ona galue i vaega uma e lua (maua ma auina atu ogalaau), nisi faʻamatalaga i latou saite.

Afai i Logstash o loʻo fausia le filifili e fai ma faʻaoga → faamama → faʻapipiʻi ona i ai lea i Vector punaoa → suiga → sisi

E mafai ona maua faʻataʻitaʻiga i totonu o faʻamaumauga.

O lenei faatonuga o se faatonuga toe teuteu mai Vyacheslav Rakhinsky. O fa'atonuga muamua o lo'o iai le geoip processing. A'o su'e le geoip mai se feso'ota'iga i totonu, na tu'uina atu e le vector se mea sese.

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

Afai ei ai se tasi e manaʻomia le faʻaogaina o le geoip, ona vaʻai lea i faʻatonuga muamua mai Vyacheslav Rakhinsky.

O le a matou faʻapipiʻiina le tuʻufaʻatasiga o Nginx (Access logs) → Vector (Client | Filebeat) → Vector (Server | Logstash) → vavae ese i Clickhouse ma eseʻese i Elasticsearch. O le a matou faʻapipiʻi 4 servers. E ui lava e mafai ona e pasia i le 3 servers.

O le polokalame e pei o lenei.

Matou te faʻapipiʻi se HTTP server emulator + utilities i luga o sapalai uma

I le avea ai o se emulator server HTTP o le a matou faʻaaogaina nodejs-stub-server от Maxim Ignatenko

Nodejs-stub-server e leai se rpm. o fai le rpm mo ia. rpm o le a fausia faʻaaoga Fedora Copr

Faʻaopoopo le faleoloa antonpatsev/nodejs-stub-server

Fa'apipi'i Clickhouse luga ole server 3

ClickHouse faʻaaogaina le SSE 4.2 faʻatonuga seti, o lea seʻi vagana ua faʻamaonia, lagolago mo ia i totonu o le faʻaogaina o loʻo faʻaaogaina e avea ma se manaʻoga faʻaopoopo. O le poloaiga lenei e siaki pe o loʻo lagolagoina e le gaosiga o loʻo iai nei le SSE 4.2:

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

Muamua e tatau ona e faʻafesoʻotaʻi le fale teu oloa:

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

Ina ia faʻapipiʻi afifi e te manaʻomia le faʻatinoina o tulafono nei:

sudo yum install -y clickhouse-server clickhouse-client

Fa'ataga clickhouse-server e fa'alogo ile kata feso'ota'iga ile faila /etc/clickhouse-server/config.xml

<listen_host>0.0.0.0</listen_host>

Suia le tulaga o le logging mai le fa'asologa i le debug

Fa'atonu fa'apipi'i:

min_compress_block_size  65536
max_compress_block_size  1048576

Ina ia faʻagaoioia le Zstd compression, sa fautuaina e aua neʻi paʻi i le config, ae faʻaaoga le DDL.

Sa le mafai ona ou mauaina pe faʻapefea ona faʻaogaina le zstd compression e ala ile DDL ile Google. O lea na ou tuua ai e pei ona i ai.

Paʻaga o loʻo faʻaogaina le zstd compression i Clickhouse, faʻamolemole faʻasoa faʻatonuga.

Ina ia amata le server o se daemon, tamoʻe:

service clickhouse-server start

Sei o tatou agai i luma i le setiina o le Clickhouse

Alu ile Clickhouse

Aua ne'i galo e fa'aopoopo le tagata fa'aoga vector i le vaega mana'omia ina ia mafai ona ia faitau faila ogalaau. Mo se faʻataʻitaʻiga, o le nginx i centos e fatuina ogalaau ma aia tatau a vaega.

usermod -a -G adm vector

Sei o tatou amata le tautua vector

systemctl enable vector
systemctl start vector

Vector logs e mafai ona vaʻaia e pei o lenei:

journalctl -f -u vector

E tatau ona i ai se faʻamatalaga faʻapea i totonu o ogalaau

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

Su'ega Fa'atiga

O suʻega e faia e faʻaaoga ai le faʻailoga a Apache.

O le httpd-tools package na faʻapipiʻiina i luga o sapalai uma

Matou te amata faʻataʻitaʻiga e faʻaaoga ai le Apache benchmark mai 4 'auʻaunaga eseese i le mata. Muamua, matou te faʻalauiloaina le telexer mata, ona matou amata suʻe lea e faʻaaoga ai le Apache benchmark. E fa'afefea ona galue ma lau mata e mafai ona e mauaina i totonu tusiga.
