Channel finder service
----------------------

Channelfinder run's on fel02. Fel02 is a VM running on a DELL R530 server
(Bld. E, Groundfloor, Server room, labeld FEL0X) as part of a esx-cluster.
It gives an overview of all PV's, IOC's used at the FEL experiment. PV'a are
searchable. Based on a mongodb database.

To collect al PVs from all known (ioc list is hardcoded in findPVs) IOCs the
script 'findPVs' must be run. It can not be used in a cron job. If some PV's
are not available it might hang. On all requested IOC's fel02's ssh key must be
registered (.ssh/authorized_keys).

The script reads the /srv/ioc/log/Database/$IOC.dbl file which gets written on
IOC reboot (on load of db files).
