Networking Tools#
There are several service programs that can assist in visualizing or mapping an AREDN® network, as well as for viewing local RF conditions near your node. Some of these programs are discussed below.
Manage Extra Static Routes#
There may be cases when you need to create extra static routes to control the flow of network traffic through your node. You can maintain your extra routes by entering them into the /etc/aredn_include/static_routes file. You must login to your node at the command line and use the vi editor to manage the routes in this file. A helpful example is provided in the file, and you can view the OpenWRT Static Routes page for additional information about managing static routes.
AREDN® Prometheus Exporter#
Prometheus is an open-source monitoring and alerting toolkit which collects and stores metrics as time series data. At given intervals it can collect metrics from AREDN® nodes having the prometheus-exporter package installed. Prometheus evaluates rule expressions, displays the results, and can trigger alerts when specified conditions are detected.
AREDN® metrics in the prometheus-exporter package include the following:
Node details (name, model, firmware, description, Lat/Lon, grid square, band, channel, width, frequency, SSID)
Memory, storage, CPU, and networking metrics
RF metrics (signal, noise, MSC rate, TX/RX packets/rates)
LQM metrics
OLSR link info
In order for Prometheus to pull metrics from a node it will use the following target URL: http://<NODE>.local.mesh/cgi-bin/metrics and metrics are returned by the node as standard text/plain content. Minimal node resources are required to support Prometheus data collection since the node only uses minimal resources whenever this URL is queried.
The AREDN® prometheus-exporter simply makes these metrics available for Prometheus to pull. For additional information about Prometheus itself, visit their website here. The following image shows Prometheus metrics for an AREDN® node being displayed by the Grafana visualization application.
KN6PLV Mesh Map#
Tim KN6PLV created these programs to discover and visualize your mesh network. They can be installed on one of your LAN-attached computers that is running a web server. This software is available for download here: KN6PLV NewMeshMap. Once you have followed the install instructions and have a working mapper, you will be able to view your mesh network in a web browser (as shown in the example below).
