# Purpose and Layout
|
|
My Grafana dashboard serves as a one-stop systems monitoring frontend.
|
|
|
|
|
|
|
|
|
|
# Grafana
|
|
|
|
# InfluxDB
|
|
|
|
| Host | Database Name | Inputs |
|
|
|:-|-:|:-|
|
|
| Main Server | `jafgraf` |
|
|
| Seedbox | `seedbox` |
|
|
| NAS | `nas` |
|
|
| PiHole | `pihole` |
|
|
|
|
The full configuration files for the main server are available at: [Jafner/docker_compose/grafana-stack](https://github.com/Jafner/docker_config/tree/master/grafana-stack).
|
|
|
|
# Telegraf
|
|
Below are excerpts from the `telegraf.conf` and accompanying files for each host. All config files are based on the [config files](https://github.com/Mbarmem/Grafana.Dashboard/blob/master/docker/telegraf/telegraf.conf) from Mbarmem's repository.
|
|
|
|
## Main Server

|
|
### Getting Forge Server Tick Info
|
|
The main server's Telegraf instance gets information about my Forge server using a chain of tools. `cron` runs `docker exec e6 rcon-cli forge
|
|
```bash
|
|
#!/bin/bash
|
|
# this script converts the output of the "forge tps" command (in the form of the .forgetps file) into json for sending to influxdb
|
|
# by default it reads from stdin and outputs to a .forgetps.json file
|
|
while IFS= read -r line; do
|
|
if [ "$line" != "" ]; then
|
|
DIM=$(echo -n "$line" | awk '{print $2}')
|
|
if [ "$DIM" = "Mean" ]; then
|
|
DIM="Overall"
|
|
fi
|
|
TPT=$(echo "$line" | grep -oE 'Mean tick time: .+ms' | awk '{print $4}')
|
|
TPS=$(echo "$line" | grep -oE 'Mean TPS: .+' | awk '{print $3}')
|
|
JSON+=\{$(echo \"dim\":\"$DIM\",\"tpt\":$TPT,\"tps\":$TPS)\},
|
|
fi
|
|
#done < .forgetps # inputs from .forgetps file
|
|
done <$1 # inputs from file passed via stdin
|
|
JSON=$(echo ${JSON} | sed 's/,$//')
|
|
|
|
#echo [${JSON}] >&1 # outputs to stdout
|
|
echo [${JSON}] > .forgetps.json # uncomment this to output to file
|
|
```
|
|
|
|
```
|
|
* * * * * cd /home/joey/docker_config/grafana-stack/scripts/ && docker exec e6 rcon-cli forge tps > .forgetps && ./forgetps-to-json.sh .forgetps
