Hi Paul,
$Hostname refers to a particular field in the log currently being
processed. NXLog wakes up to do stuff using <Schedule> and this is
independent from the log processing, thus fields are not available in
this context.
<Extension exec>
Module xm_exec
</Extension>
<Output out>
File '/mnt/raid0/nxlog/' + $Hostname + '.log'
<Schedule out_schedule>
When @hourly
Exec exec("/path/to/my/script.sh"); out->reopen();
</Schedule>
</Output>
script.sh would iterate on each relevant file under /mnt/raid0/nxlog/ and
could do whatever is needed.
Regards,
Botond
