This guide assumes you already have influxdb and grafana up and running.
To monitor our raspberry pi we need to install telegraf and do some stuff to the config file. I tried prometheus but it didn’t give me all the info I needed, like temperatures.
Telegraf install
curl -sL https://packages.grafana.com/gpg.key | sudo apt-key add -
curl -sL https://packages.grafana.com/gpg.key | sudo apt-key add -
echo "deb https://repos.influxdata.com/debian buster stable" | sudo tee /etc/apt/sources.list.d/influxdb.list
echo "deb https://packages.grafana.com/oss/deb stable main" | sudo tee /etc/apt/sources.list.d/grafana.list
sudo apt-get update
Now that all the repository lists and their dependencies are up to date, the actual installation can happen, followed by enabling and starting the services.
sudo apt-get install -y telegraf
sudo systemctl enable telegraf
sudo systemctl start telegraf
Configure telegraf to log to the influx DB
[email protected]:~ $ sudo nano /etc/telegraf/telegraf.conf
[[outputs.influxdb]] urls = ["http://your influx server:8086"]
Collector Configuration Details
Linux and machine performance:
- CPUs (defaults to all)
- Disks (per-disk IOPS)
- Network interfaces (packets, bandwidth, errors/drops)
- Mountpoints (space / inodes)
- Temperature
#In order to monitor both Network interfaces, eth0 and wlan0, uncomment, or add the next:
[[inputs.net]]
[[inputs.netstat]]
[[inputs.file]]
files = ["/sys/class/thermal/thermal_zone0/temp"]
name_override = "cpu_temperature"
data_format = "value"
data_type = "integer"
[[inputs.exec]]
commands = ["/opt/vc/bin/vcgencmd measure_temp"]
name_override = "gpu_temperature"
data_format = "grok"
grok_patterns = ["%{NUMBER:value:float}"]To be able for telegraf to gather info about the GPU, we need to add the telegraf user into video group:
sudo usermod -G video telegraf
