Kutumiza zipika za Nginx json pogwiritsa ntchito Vector ku Clickhouse ndi Elasticsearch

vekitala, opangidwa kuti asonkhanitse, kusintha ndi kutumiza zipika, ma metric ndi zochitika.

→ Github

Polembedwa m'chinenero cha Rust, imadziwika ndi machitidwe apamwamba komanso kuchepa kwa RAM poyerekeza ndi zofanana zake. Kuphatikiza apo, chidwi chachikulu chimaperekedwa ku ntchito zokhudzana ndi kulondola, makamaka, kuthekera kosunga zochitika zosatumizidwa ku buffer pa disk ndikusintha mafayilo.

Zomangamanga, Vector ndi rauta yamwambo yomwe imalandira mauthenga kuchokera kwa amodzi kapena angapo magwero, ngati mukufuna kugwiritsa ntchito mauthengawa kusintha, ndi kuwatumiza kwa mmodzi kapena angapo ngalande.

Vector ndi m'malo mwa filebeat ndi logstash, imatha kugwira ntchito zonse ziwiri (kulandira ndi kutumiza zipika), zambiri pa iwo. malo.

Ngati mu Logstash unyolo umamangidwa ngati cholowetsa → fyuluta → zotulutsa ndiye mu Vector ndizomwe zili magwero → amasintha → imamira

Zitsanzo zitha kupezeka m'zolembedwa.

Langizo ili ndi malangizo osinthidwa kuchokera Vyacheslav Rakhinsky. Malangizo apachiyambi ali ndi geoip processing. Poyesa geoip kuchokera pa netiweki yamkati, vekitala idapereka cholakwika.

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

Ngati wina akufunika kukonza geoip, onani malangizo oyambira kuchokera Vyacheslav Rakhinsky.

Tikonza kuphatikiza kwa Nginx (Kufikira zipika) → Vector (Client | Filebeat) → Vector (Server | Logstash) → padera mu Clickhouse komanso padera mu Elasticsearch. Tikhazikitsa ma seva 4. Ngakhale mutha kuzilambalala ndi ma seva atatu.

Chiwembu ndi chinthu chonga ichi.

Timayika HTTP seva emulator + zofunikira pa maseva onse

Monga emulator ya seva ya HTTP tidzagwiritsa ntchito nodejs-stub-server от Maxim Ignatenko

Nodejs-stub-server ilibe rpm. ndi pangani rpm kwa izo. rpm idzapangidwa pogwiritsa ntchito Fedora Copr

Onjezani chosungira antonpatsev/nodejs-stub-server

Ndinakonza nthawi yoyankha ya stub_http_server mu fayilo ya /var/lib/stub_http_server/stub_http_server.js kotero kuti panali zolemba zambiri.

Tiyeni tiyambitse stub_http_server.

Kukhazikitsa kwa Clickhouse pa seva 3

ClickHouse imagwiritsa ntchito malangizo a SSE 4.2, kotero pokhapokha atanenedwa mwanjira ina, kuthandizira kwa purosesa yogwiritsidwa ntchito kumakhala chofunikira padongosolo. Nali lamulo loti muwone ngati purosesa yamakono imathandizira SSE 4.2:

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

Choyamba muyenera kulumikiza malo ovomerezeka:

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

Kuti muyike phukusi muyenera kuyendetsa malamulo awa:

sudo yum install -y clickhouse-server clickhouse-client

Lolani clickhouse-server kuti imvetsere khadi la netiweki mufayilo /etc/clickhouse-server/config.xml

Kusintha mulingo wodula mitengo kuchokera pakufufuza kupita ku debug

Zokonda zapakatikati:

min_compress_block_size  65536
max_compress_block_size  1048576

Kuti muyambitse kukakamiza kwa Zstd, adalangizidwa kuti asakhudze kasinthidwe, koma m'malo mwake agwiritse ntchito DDL.

Sindinapeze momwe ndingagwiritsire ntchito zstd compression kudzera pa DDL mu Google. Choncho ndinazisiya zilili.

Anzanu omwe amagwiritsa ntchito zstd compression ku Clickhouse, chonde gawanani malangizowo.

Kuyambitsa seva ngati daemon, thamangani:

service clickhouse-server start

Tsopano tiyeni tipitirire kukhazikitsa Clickhouse

Pitani ku Clickhouse

Не забудте добавить юзера vector в нужную группу что бы он мог читать log файлы. Например, nginx в centos создает логи с правами группы adm.

usermod -a -G adm vector

Kukula kwa tebulo la zipika ndi 857.19 MB.

Kukula kwa data yomweyi mu index mu Elasticsearch ndi 4,5GB.

Ngati simunatchule zambiri mu vector mu magawo, Clickhouse imatenga 4500/857.19 = 5.24 kuchepera kuposa mu Elasticsearch.

Mu vector, gawo la compression limagwiritsidwa ntchito mwachisawawa.
