Query Service
Query service is the interface between frontend and databases. It is written in Golang. It will have modules for all supported databases. Query service is responsible to:
- parse the request from Frontend
- create relevant Clickhouse queries (and all other supported database queries)
- parse response from databases and handle error if any
- clickhouse response in the format accepted by Frontend
Complete the clickhouse setup locally.
- Comment out the query-service and the frontend section in
signoz/deploy/docker/clickhouse-setup/docker-compose.yaml - Change the alertmanager section in
signoz/deploy/docker/clickhouse-setup/docker-compose.yamlas follows:
alertmanager:
image: signoz/alertmanager:0.23.4
volumes:
- ./data/alertmanager:/data
expose:
- "9093"
ports:
- "8080:9093"
# depends_on:
# query-service:
# condition: service_healthy
restart: on-failure
command:
- --queryService.url=http://172.17.0.1:8085
- --storage.path=/data
- Run the following:
cd signoz/
If you are using x86_64 processors (All Intel/AMD processors) run sudo make run-x86
If you are on arm64 processors (Apple M1 Macs) run sudo make run-arm
Backend Configuration
-
Open ./constants/constants.go
- Replace
const RELATIONAL_DATASOURCE_PATH = "/var/lib/signoz/signoz.db"
withconst RELATIONAL_DATASOURCE_PATH = "./signoz.db".
- Replace
-
Query Service needs below
envvariables to run:
export ClickHouseUrl=tcp://localhost:9001
export STORAGE=clickhouse
export ALERTMANAGER_API_PREFIX=http://localhost:9093/api/
Build and Run locally
cd pkg/query-service
go build -o build/query-service main.go
ClickHouseUrl=tcp://localhost:9001 STORAGE=clickhouse build/query-service --prefer-delta=true
Frontend Configuration for local query-service.
- Set the following environment variables
export FRONTEND_API_ENDPOINT=http://localhost:8080
- Run the following
cd signoz\frontend\
yarn install
yarn dev
Note:
If you use go version 1.18 for development and contributions, then please checkout the following issue. https://github.com/SigNoz/signoz/issues/1371
