Loki On VictoriaMetrics
This project experimentally supports the loki protocol on the VictoriaMetrics Cluster, and the performance may be better than original loki.
More discussion can be found at VictoriaMetrics#816
Supported
- LogQL, extends MetricsQL to support filter expressions and full PromQL & MetricsQL support for querying metrics.
- Major HTTP API
/loki/api/v1/query/loki/api/v1/query_range/loki/api/v1/label&/loki/api/v1/labels/loki/api/v1/label/<name>/values/loki/api/v1/tail(websocket)/loki/api/v1/push
- Additional support for prometheus-style data writing via tcp, like
loki{component="parser",level="WARN"} "app log line"
How to build & run
$ make all
$ bin/vmstorage
$ bin/vmselect -storageNode 127.0.0.1:8401
$ bin/vminsert -storageNode 127.0.0.1:8400 -importerListenAddr 127.0.0.1:2003
Set loki datasource endpoint as http://127.0.0.1:8481/select/0/, If you call it manually, the full URL is http://127.0.0.1:8481/select/0/loki/api/v1/query_range.
Test insert logs with tcp:
$ nc 127.0.0.1 2003
loki{component="parser",level="WARN"} "app log line"
If you want to call push api to insert data, use http://127.0.0.1:8480/insert/0/loki/api/v1/push.
