grafana_af2c

self-hosting grafana for monitoring:

• Server data (e.g disk usage)
• presence monitoring (subscribers to all platform, activity and shit) for the AF2C
• for communes

dependencies (for debian): what I've installed:

• docker-clean/stable,now 2.0.4-5 all [installed]
• docker-compose/stable,now 1.29sudo docker-compose up.2-3 all [installed]
• docker-doc/stable,now 20.10.24+dfsg1-1 all [installed]
• docker-registry/stable,now 2.8.2+ds1-1 amd64 [installed]
• docker.io/stable,now 20.10.24+dfsg1-1+b3 amd64 [installed]
• docker/stable,now 1.5-2 all [installed]

1. we need to set up alone grafana. we will use docker-compose for this 1.1 prepare working directory for grafana and configs for it mkdir grafana-docker

   1.2 prepare docker-compose.yaml touch docker-compose.yml

   1.3 edit docker-compose.yml (I will give docker-compose.yml) DISCLAIMER: we will use bind mounts

   1.4 everything is ready? then we start up container sudo docker-compose up and connect with localhost (by default it should be localhost:3000)

2. because we start with monitoring what's going on our own server, we will deploy prometheus and node_exporter now. let's start with node_exporter becasue this is the source of data about our server

   2.1 add docker config for node exporter

   2.2 add docker config for prometheus

HUGE DISCLAIMER ABOUT NETWORKING: technically, every application has own container which mean it also has its own networking rules. for tests, I connected it together that:

1. turn on containers: docker-compose up -d
2. list working containers: docker ps
3. inspect them: docker inspect
4. look for "NetworkSettings" and sub-category Networks
5. look for value in "IPAddress" because this is our "localhost" for particular container
6. take this value and get access to container with this pattern http://:assigned_port
