isochron-daemon8

Usage

Overview

This command starts a long-running process that listens for connections from an isochron orchestrator. The daemon can receive further instructions from the orchestrator.

Options

-h, --help

prints the short help message and exits

-l, --log-file <PATH>

after becoming a daemon, the program can redirect its standard output and standard error to the text file specified here. Optional, defaults to /dev/null.

-p, --pid-file <PATH>

after spawning a daemon process, the main program overwrites the text file provided here with a single line containing a decimal number representing the process ID of the daemon. Optional, defaults to no PID file being created.

-P, --stats-port <NUMBER>

specify the TCP port on which the daemon program is listening for incoming connections. This socket is used for management and statistics. Optional, defaults to port 5000.

-S, --stats-address <NUMBER>

specify the IP address on which the daemon program is listening for incoming connections. This socket is used for management and statistics. Supports binding to a given network device using the address%device syntax (example: --stats-address ::%vrf0). Optional, defaults to ::, with a fallback to 0.0.0.0 if IPv6 is not available.

Examples

To start and then stop a daemon and view its log file:

isochron daemon \
    --log-file isochron.log \
    --pid-file isochron.pid \
    --stats-port 5001
tail -F isochron.log &
kill $(pidof tail)
kill $(cat isochron.pid)
