prosafe-exporter 0.4.7

Prometheus metrics exporter for NETGEAR switches of the Smart Managed Plus series.

prosafe_exporter_python

Open metrics exporter for NETGEAR switches of the Smart Managed Plus series to provide data to databases such as Prometheus or InfluxDB.

What is the purpose?

NETGEAR switches of the Smart Managed Plus series do not provide a standards conform interface for providing statistics of traffic and other information. There is no support for monitoring protocols such as SNMP. Still these switches are deployed in large numbers in professional and private environments where monitoring of the switches is highly desired. A common solution for monitoring is to store the data in a Prometheus database and visualize and alert with tools such as Grafana. prosafe_exporter_python provides a tool that colelcts the data from the switches webinterface and provides it using the OpenMetrics format that can be directly used in Prometheus or Influx scrape jobs.

Exported Metrics

metric	description	labels
prosafe_switch_info	Information about the switch exposed as labels	hostname, product_name, switch_name, serial_number, mac_adresse, bootloader_version, firmware_version, dhcp_mode, ip_adresse, subnetmask, gateway_adresse
prosafe_receive_bytes_total	Incoming transfer in bytes	hostname, port
prosafe_transmit_bytes_total	Outgoing transfer in bytes	hostname, port
prosafe_error_packets_total	Transfer error in packets	hostname, port
prosafe_link_speed	Link speed in Mbps	hostname, port
prosafe_max_mtu*	Maximum MTU	hostname, port

* not available in all firmware versions

Usage

Setup a config.yml

global: 
  retrieve_interval: 20.0
  retries: 10
  host: "0.0.0.0"
  port: 9493
switches: 
  - hostname: "192.168.0.100"
    password: "password123"
  - hostname: "192.168.0.200"
    password: "password123"

Run with:

prosafe_exporter path/to/your/config.yml

In prometheus configure a scrape job, e.g. like this:

scrape_configs:
 - job_name: 'prosafe_switches'
    static_configs:
      - targets:
        - "prosafe_exporter:9493"
    metrics_path: /probe
    scrape_interval: 60s

In InfluxDB configure a scrape job like this: Influx scrape configuration

Docker

prosafe_exporter is also available as a stand-alone docker container from DockerHub

Query Example for Grafana

Outgoing data rate of port 1 on 192.168.0.123 is below.

rate(prosafe_transmit_bytes_total{instance="192.168.0.123", port="1"}[1m])

Grafana Screenshot

This is how the data could look like in Grafana with an example configuration:

Tested Switches

The following Switches are continously tested with real hardware:

• GS108Ev3
• GS108PEv3

Other Devices can be regression tested with prerecorded datasets. If you want to contribute with data from a switch not listed, please contact me or open an issue.

Tested Firmware

• V2.06.14GR
• V2.06.14EN
• V2.06.03EN

If you want to contribute with data from a switch not listed here, please contact me or open an issue.

Reporting Issues

Please feel free to open an issue at GitHub Issue page to report problems you found.

Known Issues

• May not work with older firmware, not all firmware versions are tested
• Does not work with Japanese firmware
