Hastic
Hastic needs Prometheus or InfluxDB instance for getting metrics.
Build from source (Linux)
Prerequirements
- Install cargo (required version: >=1.49)
- Install node.js >=10.x
- Install yarn
- Install x86_64-unknown-linux-musl:
rustup target add x86_64-unknown-linux-musl
- musl-tools:
sudo apt install musl-tools
Build
make
Configure
Hastic can be configured using config-file or environment variables.
At first, choose which datasource you'll be using: prometheus
or influx
. Only one can be used at a time.
Config-file
- copy the config example to the release directory:
cp config.example.toml release/config.toml
- edit the config file, e.g. using
nano
:
nano release/config.toml
Environment variables
All config fields are also available as environment variables with HASTIC_
prefix
Variable name structure:
- for high-level fields:
HASTIC_<field_name>
, e.g.HASTIC_PORT
- for nested fields:
HASTIC_<category_name>__<field_name>
, e.g.HASTIC_PROMETHEUS__URL
Environment variables can be set either by exporting them (they'll be actual until a bash-session is closed):
export HASTIC_PORT=8000
export HASTIC_PROMETHEUS__URL=http://localhost:9090
export HASTIC_PROMETHEUS__QUERY=rate(go_memstats_alloc_bytes_total[5m])
or specifing them in a run command (they'll be actual only for one run):
HASTIC_PORT=8000 HASTIC_PROMETHEUS__URL=http://localhost:9090 HASTIC_PROMETHEUS__QUERY=rate(go_memstats_alloc_bytes_total[5m]) ./release/hastic
Run
cd release
./hastic
open http://localhost:4347
