DESCRIPTION
Onionprobe is a tool for testing and monitoring the status of Tor Onion Services sites.
It can run a single time or continuously to probe a set of onion services endpoints and
paths, optionally exporting to Prometheus.

Test and monitor onion services
optional arguments:
-h, --help show this help message and exit
-c CONFIG, --config CONFIG
Read options from configuration file. All command line parameters can be specified inside a YAML file. Additional command line parameters override those set in the configuration file.
-v, --version show program's version number and exit
--circuit_stream_timeout CIRCUIT_STREAM_TIMEOUT
Sets how many seconds until a stream is detached from a circuit and try a new circuit

--rounds ROUNDS Run only a limited number of rounds (i.e., the number of times that Onionprobe tests all the configured endpoints). Requires the "loop" option to be enabled. Set to 0 to disable this limit.
--shuffle, --no-shuffle
Shuffle the list of endpoints at each probing round (default: True)
--sleep SLEEP Max random interval in seconds to wait between each round of tests
--socks_port SOCKS_PORT

FILES

LIMITATIONS
Onionprobe currently has the following limitations:
1. Only works for Onion Services websites, i.e, those served via either HTTP or HTTPS.
2. Currently Onionprobe probes runs in a single thread.
3. For other limitations, check the list of issues available at the Onionprobe source code
repository.
SEE ALSO
The README file distributed with Onionprobe contains the full documentation.
