# Docker Based Latency Monitor
Docker container which tracks latency of one or many hosts and reports to InfluxDBv2.
Docker container(s) which tracks latency of one or many hosts and reports to InfluxDBv2.
## Description
@@ -17,26 +17,45 @@ It´s based on python3 an makes usage of following python libraries:
- configparser
- time
You can use it in *standalone* or *full stack* mode.
**Standalone:**
- Just the latency-monitor container which sends data to an external InfluxDB2 Server
**Full Stack:**
- Traefik container as Proxy (full TLS support)
- InfluxDB2 container, fully setup and ready to take data
- Grafana container, fully setup and connected (but without dashboards)
- latency-monitor container sending data to the InfluxDB2 container
## Requirements
- Docker (CE)
- Docker-Compose
- InfluxDB Version >= 2
- pythonping needs root privileges so same for the container
## Configuration (GENERAL)
Configuration can be passed via ENV **OR** configuration file.
In case of using the ENV option you are just able to monitor **ONE** target for more targets please use the configuration file.
Also some influx connection options are just configurable via config file but normally they are not needed.
Per default the python influx connector will cache all replies and sends them bundled every 30 seconds to the Influx DB.
The container will be build at 1st start.
### Behaviour
Per default the used python influxdb connector will cache all replies and sends them bundled every 30 seconds to the Influx DB.
Actually the latency-monitor container is build on demand, a dockerhub image is on the roadmap...
You can find everything under *./Docker_Build/* and in the python program itself [latency_monitor.py](./Docker_Build/latency_monitor.py)
## Requirements
-----
- Docker
- Docker-Compose
- InfluxDB Version >= 2
- pythonping needs root privileges so same for the container

## Config File
-----
### Config File
**Instead** of using the ENV variables you can use a config file.
**Keep in mind it´s a OR decision not a AND**
See [template_config.ini](./Docker_Build/template_config.ini)
See [./latency-monitor/config.ini](./latency-monitor/config.ini)
Rename the file to *config.ini* make your changes and add it as a volume mount to the container:
### Docker-Compose Style
#### Docker-Compose Style
uncomment:
```
volumes:
- /YOUR_PATH/config.ini:/app/config.ini
# - ./latency-monitor/config.ini:/app/config.ini:ro # UNCOMMENT IF NEEDED

-----
-----
## Configuration (Standalone)
1st thing to do is creating the *docker-compose.yml* from [docker-compose-standalone.yml](./docker-compose-standalone.yml):
```
cp docker-compose-standalone.yml docker-compose.yml
```
### Variables
Below paragraph:
```
####################################################
# LATENCY-MONITOR
####################################################
```
in the **.env** file *(env needs to be renamed to .env)* configure following variables:
- YOUR_ORGANIZATION
- YOUR_BUCKET_NAME
- YOUR_ADMIN_TOKEN
- YOUR_MONITORED_TARGET
- YOUR_MONITORED_TARGET_TIMER
- YOUR_MONITORED_TARGET_LOCATION
### Lets go
```
docker-compose up -d latency-monitor
```
should do the job

## Compose Files
## Configuration (Full-Stack)
### FULL-STACK
### Easy peasy automatic mode
1st thing to do is creating the *docker-compose.yml from [docker-compose-full_stack.yml](./docker-compose-full_stack.yml):
Have a look at [./setup-full_stack.sh](./setup-full_stack.sh)
Just create a valid *.env* File by:
```
cp docker-compose-full_stack.yml docker-compose.yml
cp env .env
```
#### Certificate
and edit it to your needs.
*Traefik* will act as a proxy and ensures the usage of TLS so it needs your certificate and key file.
within the *docker-compose.yml* you will find:
After everyting within *.env* is in order just do:
```
- ./traefik/mycert.crt:/certs/cert.crt:ro
- ./traefik/mycert.key:/certs/privkey.key:ro
./setup-full_stack.sh
```
so please place your certificate file as *./traefik/mycert.crt* and the key file as *./traefik/mycert.key*.
Everything should be right in place now.
Thats it
Just the certificates are missing look [here](#certificate)
Now run it and mybe pick a example dashboard for grafana from [here](#grafana-dashboard-examples)
