[프로메테우스/ 그라파나] Cosmos-Exporter 설치 및 설정(prometheus, grafana)

Cosmos-Exporter 설치

[Cosmos-exporter]
https://github.com/solarlabsteam/cosmos-exporter/releases/

위 링크에 가서 최신 버전을 다운받아 폴더에 wget 으로 설치

• wget https://github.com/solarlabsteam/cosmos-exporter/releases/download/v0.3.0/cosmos-exporter_0.3.0_Linux_x86_64.tar.gz

• tar xvfz cosmos-exporter-*

• ./cosmos-exporter
  (에러 뜰 수도 있음, denom 설정 해줘야 함.)

Background 에서 프로세스가 돌아가도록 설정해주기

• sudo cp ./cosmos-exporter /usr/bin
• sudo vim /etc/systemd/system/cosmos-exporter.service

[Unit]
Description=Cosmos Exporter
After=network-online.target

[Service]
User=root <username으로 설정>
TimeoutStartSec=0
CPUWeight=95
IOWeight=95
ExecStart=cosmos-exporter \
        --bech-prefix=xpla \
        --denom=XPLA \
        --denom-coefficient=1000000000000000000
Restart=always
RestartSec=2
LimitNOFILE=800000
KillSignal=SIGTERM

[Install]
WantedBy=multi-user.target

ExecStart 옵션을 저렇게 지정해주어야 denom 에러가 뜨지 않는다. cosmos 코인 각각 설정값이 다름.

• sudo systemctl enable cosmos-exporter
• sudo systemctl start cosmos-exporter
• sudo systemctl status cosmos-exporter

9300번 port가 열려있는지 확인.

sudo journalctl -u cosmos-exporter -f --output cat
( 실시간 로그 확인 )

프로메테우스 서버

• vim prometheus.yml
