User's Manual UPS control system

/sbin/apcnisd
The advantage of running the network information server standalone is that
if for some reason, a client causes the network server to crash, it will not
affect the operation of apcupsd.
apcupsd System Logging
The apcupsd philosophy is that all logging should be done through the sys-
log facility (see: man syslog). This is now implemented with the exceptions
that STATUS logging, for compatibility, with prior versions is still done to
a file, and EVENTS logging can be directed to a “temporary” file so that
it can be reported by the network information server.
Logging Types
apcupsd splits its logging into four separate types called:
1. DEBUG
2. DATA
3. STATUS
4. EVENTS
Debug logging consists of debug messages. Normally these are turned on
only by developers, and currently there exist very few of these debug mes-
sages.
Logging
Data logging consists of periodically logging important data concerning the
operation of the UPS. See the Data Logging (see DATA Logging) section of
this manual for more details.
Logging
Status logging consists of logging all available information known about your
UPS as a series of ASCII records. This information is also made available
by the apcupsd network information server.
