FACILITY<log-facility> The facility directive can be used to change
the system logging class or facility. The default is DAEMON. This
parameter can be useful if you wish to direct the apcupsd system
logging information to other than your system default files. See the
Logging section of this manual for additional details.
Configuration Directives for Sharing a UPS
The following directives apply to the master/slave networking mode of
apcupsd where multiple machines can be powered by the same UPS. One
machine, the master, will have a serial port connection to the UPS, and
the other machines, the slaves, will obtain their information via the network
from the master.
Note, as of version 3.10.x, the old master/slave code is by default turned
off in the configuration. You must explicitly enable it by including a
--enable-master-slave option on your ./configure command before
building the source.
In addition to the old master/slave code, there is now a new network driver
enabled with --enable-net (default disabled) that can be used to control a
slave from any version of apcupsd running NIS. This is a much more flexible
system of controlling slaves because a slave machine that also has NIS turned
on can thus act as a master for another slave with --enable-net turned
on. With this mode turned on, the slave obtains the address of the master
from the DEVICE directive, which takes the form hostname[:port] as a
consequence, none of the directives apply for this form of networking. In
addition, for this mode to work, you must specify UPSTYPE net so that
the proper driver is loaded.
The remainder of this section presents directives that apply to the old mas-
ter/slave code that must be enabled by the enable-master-slave configu-
ration option.
UPSCLASS <class of operation> [ standalone — shareslave — share-
master ] and [ netslave — netmaster ] are valid types. [ standalone —
netslave — netmaster ] are tested classes. [ shareslave — sharemaster
] classes are being tested.
The default is standalone and should be used for all machines pow-
ered by the UPS and having a serial port connection to the UPS, but
