Pléifidh an t-alt seo an tionscadal , a léifidh logaí nginx agus iad a sheoladh chuig braisle Clickhouse. De ghnáth úsáidtear ElasticSearch le haghaidh logaí. Éilíonn Clickhouse níos lú acmhainní (spás diosca, RAM, LAP). Taifeadann Clickhouse sonraí níos tapúla. Déanann Clickhouse sonraí a chomhbhrú, rud a fhágann go bhfuil na sonraí ar an diosca níos dlúithe fós. Tá na buntáistí a bhaineann le Clickhouse le feiceáil i 2 shleamhnán ón tuarascáil
Chun anailísíocht a fheiceáil bunaithe ar logaí, cruthóimid painéal do Grafana.
Aon duine a bhfuil suim acu, fáilte romhat chuig cat.
Suiteáil nginx, grafana ar an mbealach caighdeánach.
Suiteáil braisle clickhouse ag baint úsáide as ansible-playbook ó .
Bunachair sonraí agus táblaí a chruthú i Clickhouse
Sa chás seo Déantar cur síos ar cheisteanna SQL maidir le bunachair shonraí agus táblaí a chruthú do nginx-log-collector i Clickhouse.
Déanaimid gach iarratas ceann ar cheann ar gach freastalaí i mbraisle Clickhouse.
Nóta tábhachtach. Sa líne seo, ní mór logs_cluster a chur in ionad d'ainm braisle ón gcomhad clickhouse_remote_servers.xml idir "remote_servers" agus "shard".

Tá súil agam go mbeidh an pobal páirteach i bhforbairt/tástáil agus úsáid nginx-log-collector.
Agus nuair a chuireann duine nginx-log-collector i bhfeidhm, inseoidh siad duit cé mhéad a shábháil siad ar dhiosca, RAM, agus LAP.
