[Orca-users] Re: Orca not pick up new logs (was Re: plot ambien t and cpu temperature on E450)

[Blair Zajac]

Since Orca reads the input data files every "interval" seconds, it
can warn the sysadmin when it sees that the file has not been
updated in "late_interval" number of seconds.  This warning can be
used to check if the process has died and restart it.

In your case, if your measurement is not consistent with the
"interval" of 300 seconds, say if you measure every 600 seconds, then
you need to change the "interval" parameter.  If you do measure every
300 seconds with some variation, then either lower the variation or
increase the "late_interval".  In your case, the "late_interval" is
330 seconds:

    late_interval	interval + 30
