# isochron-daemon(8)

Start an isochron program waiting for management commands

## NAME

isochron-daemon - Start an isochron program waiting for management commands

## SYNOPSIS

**isochron** daemon \[*OPTIONS*\]

## DESCRIPTION

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)
  ```
