Logging

Events logging consists of logging events as they happen. For example,

successful startup, power fail, battery failure, system shutdown, ...

See the manual section on customizing event handling (see

Customizing Event Handling) for more details.

Implementation Details

In order to ensure that the data logged to syslog() can be directed to diﬀerent

ﬁles, I have assigned syslog() levels to each of our four types of data as

follows:

1. 1. DEBUG logging has level LOG

DEBUG

2. 2. DATA logging has level LOG

INFO

3. 3. STATUS logging has level LOG

NOTICE

4. 4. EVENTS logging has levels LOG WARNING, LOG ERR,

LOG CRIT, and LOG ALERT

It should be noted that more work needs to be done on the precise deﬁnitions

of each of the levels for EVENTS logging. Currently, it is roughly broken

down as follows:

LOG WARNING general information such as startup, etc.

LOG ERR an error condition detected, e.g. communications problem with

the UPS.

LOG CRIT a serious problem has occurred such as power failure, running

on UPS batteries, ...

LOG ALERT a condition that needs immediate attention such as pending

system shutdown, ...

The default Facility for syslog() logging is DAEMON, although this can be

changed with the FACILITY directive in apcupsd.conf. In the following

example, we should the facility as local0.
