tor_exporter

Small Prometheus exporter for the tor daemon written in Go. Forked from squeed/prometheus-tor.

Usage

tor_exporter (--tor.control-socket /var/run/tor/control | --tor.control-port localhost:9051)

The default port for serving the metrics is 9105, can be changed with flag: --web.listen-address.

Docker

A docker image is also provided.

docker run -d -p 9105:9105 -v /var/lib/tor/control_auth_cookie:/var/lib/tor/control_auth_cookie:ro,z \
martinohansen/tor_exporter --tor.control-port example:9051

Installation

The typical way of installing in Go should work.

go install

Metrics exposed

• tor_connection_circuits - the number of open circuits
• tor_connection_streams - the number of open streams
• tor_connection_orconns - the number of open ORConns
• tor_traffic_read_bytes, tor_traffic_written_bytes - cumulative inbound and outbound traffic

To-do

• Let's cheat and assume the CircuitID is sequential. Instant counter!
