CMonitor

Another container hacky monitor for sth cadvisor could not covered. CMonitor is designed for some missing metrics to cadvisor, such as process level metrics and tcp states etc.

design

CMonitor is dead simple and just:

• use docker cp to sync modules(now, they are shells);
• use docker exec to execute them and collect metrics.

limitation

CMonitor uses docker exec, docker cp to collect metrics, it's really unsafe and not predictable...

build

git clone [email protected]:Colstuwjx/cmonitor.git
cd cmonitor
docker build -t cmonitor:0.1 .

ship

docker push cmonitor:0.1

prepare configs

cp src/config/config.yml /opt/cmonitor-config.yml

run

# no TLS
docker run -itd \
    --net host \
    --restart always \
    -v /var/run/docker.sock:/var/run/docker.sock \
    -v /opt/cmonitor-config.yml:/config/config.yml \
    -e CONFIG_PATH=/config/config.yml \
    --name cmonitor \
    cmonitor:0.1

# with TLS, you need write TLS configs into cmonitor-config.yml
docker run -itd \
    --net host \
    --restart always \
    -v /var/run/docker.sock:/var/run/docker.sock \
    -v /opt/cmonitor-config.yml:/config/config.yml \
    -v /etc/pki/CA/:/etc/pki/CA/ \
    -e CONFIG_PATH=/config/config.yml \
