INTERVAL in clientlaunch.cfg

Question about the INTERVAL setting in clientlaunch.cfg:

Per the man page (for hobbitlaunch.cfg)

The *INTERVAL* keyword defines how often this command is executed. {...}
Intervals can be specified in seconds (if you just put a number there), or
in minutes (5m), hours (2h), or days (1d).

So I was trying to get netstat -s working every second.

[hiflow_net]
        ENVFILE /usr/local/hobbit/client/etc/hobbitclient.cfg
        CMD /usr/local/hobbit/client/ext/hiflow_net
        LOGFILE=/tmp/hilog
        INTERVAL 1

hobbitlaunch has a built-in safety catch, so you cannot run a
task more often than once every 5-10 seconds. That's to prevent
it from fork-bombing your system.

If you really need that, use a wrapper around your script:

   #!/bin/sh

   while 1
   do
       /usr/local/hobbit/client/ext/hiflow_net
       sleep 1
   done

and run the wrapper-script from hobbitlaunch (without any
INTERVAL setting since it keeps running).
