mesh_metrics.sh

Description

This script allows interfacing directly with a Meshtastic node to poll repeaters for their status over the mesh network. It only requires a computer setup with Prometheus or Victoria Metrics, node_exporter (at this time), and a serial connection to a Meshtastic radio. It has no requirment for internet access.

Requirements:

• Prometheus or Victoria Metrics
• node_exporter
• Meshtastic_cli
• Meshtastic client connected via USB or via network.
• Prometheus alertmanager, used to change alerting nodes color in the geomap panel (optional).

How to use

-f </path/devfile.lst> Device list

-d </path/to/node_exporter/folder>

-i Create individual metrics file per node.

-m [serial | ip] Interface mode.

-p /dev/tyy.usbmodem[0-9] | <Host/IP>

-v Output verbose debug info

-P Password to decrypt your openssl encrpted device list.

NOTE: Arguments required are -f <path/device.lst> -p

With no output directory defined, the script prints to stdout on the screen.

./mesh-metrics.sh -f dev.lst -p /dev/tty.usbmodem0

Example using network:

./mesh-metrics.sh -f dev.lst -p 192.168.1.21 -m ip

Device file

Device file options: Only the NodeID is required to pole nodes though all the commas need to be represented on each line. All other fields are optional, though GPS coordinates are needed for the dashboard map to post points.

Use

Run via a CRON job at an interval suitable for your network. The larger the network, the dwell time should be increased to keep channel utilization values realistic and not lose metrics.

Grafana

The Dashboard geomap plugin can change the point color to red for alerting nodes which requires Prometheus alertmanager to be installed and configured. This requirement is a limitation of the geomap plugin and grafana not having any means to otherwise relay that data, or it's intirely possibile I just have not found how to get that alert data from Grafana into the Geomap plugin... (I'm still searching to reduce any extra dependancies).

TODO:

• Make make the script run stand alone with interupt and PID.
• Create Open-RC startup
• Create systemd startup
• Rewrite script in python to leaverage python meshtastic-cli.
