upsstats.html - HTML template for Network UPS Tools upsstats
This file is used by upsstats.cgi(8) to generate status pages. Certain
commands are recognized, and will be replaced with various status
elements on the fly.
Commands can be placed anywhere on a line, but must start and end with
@. Any extra characters before or after the commands will be passed
through unchanged. It is allowed to use more than one command on a
single line, as long as each command has its own start and end
character. If you need to use the @ sign, use @ to prevent it from
being treated as a start character.
Some commands begin blocks - sections of the template that will be
included, excluded, or repeated depending on certain parameters.
BLOCK CONTROL - ITERATION
Starts a block that will be repeated for each MONITOR directive
in the hosts.conf(5). This is how you can generate pages that
monitor all of your systems simultaneously.
Ends a FOREACHUPS block.
BLOCK CONTROL - MATCHING SPECIFIC CASES
Starts a block that will only be printed if the variable var is
supported by the current UPS. This is generally used to
suppress "not supported" messages by avoiding the label and
variable call entirely.
@IFEQ var value@
Starts a block if the value returned from the variable var
@IFBETWEEN varlow varhigh varvalue@
Starts a block if the value returned by the variable varvalue is
between the values returned by the variables varlow and varhigh.
@ELSE@ If the previous IF-command did not match, perform this instead.
Ends an IF/ELSE-block.
BLOCK CONTROL - ADVANCED EXPRESSIONS
Even though the parser is pretty limited, it's still possible to create
rather advanced expressions. The key to this is the fact that multiple
block control commands are AND:ed. This is illustrated with an example
(more examples are available in upsstats.html).
This UPS knows both ambient temperature and humidity.
This UPS only knows ambient humidity.
This UPS only knows ambient temperature.
This UPS knows nothing, how annoying.
Insert the ambient temperature in the current temperature scale.
Insert the current date and time. The format string is passed
to strftime, so almost anything is possible. See strftime(3)
for possible values.
Insert the entity for degrees (°) and either C or F
depending on the current temperature scale.
@HOST@ Insert the designation of the host being monitored, like
Insert the host's description from hosts.conf(5).
Insert a link to upsstats.cgi with the "host" variable set to
the current UPS. This is only useful within a FOREACHUPS block.
@IMG varname [extra]@
Insert an IMG SRC to upsimage.cgi(8) for one of these status
battery.charge - Battery charge - a percentage
battery.voltage - The charge on the battery in volts
input.frequency - Incoming utility frequency (Hz)
input.voltage - Incoming utility voltage
input.L1-L2.voltage - Incoming voltage, L1-L2 (3phase)
input.L2-L3.voltage - Incoming voltage, L2-L3 (3phase)
input.L3-L1.voltage - Incoming voltage, L3-L1 (3phase)
output.frequency - Outgoing utility frequency (Hz)
output.voltage - Outgoing voltage (from the UPS)
output.L1-L2.voltage - Outgoing voltage, L1-L2 (3phase)
output.L2-L3.voltage - Outgoing voltage, L2-L3 (3phase)
output.L3-L1.voltage - Outgoing voltage, L3-L1 (3phase)
output.L1.power.percent - UPS load, L1 (3phase)
output.L2.power.percent - UPS load, L2 (3phase)
output.L3.power.percent - UPS load, L3 (3phase)
ups.load - UPS load - percentage
ups.temperature - UPS temperature
extra is where you can put additional definitions. Right now
the valid definitions are colors for various parts of the bars
drawn by upsimage.cgi. Possible color names are:
back_col - background color
scale_num_col - scale number color
summary_col - summary color (number at the bottom)
ok_zone_maj_col - major scale color for the normal
ok_zone_min_col - minor scale color for the normal
neutral_zone_maj_col - major scale color for the neutral
neutral_zone_min_col - minor scale color for the neutral
warn_zone_maj_col - major scale color for the warning zone
warn_zone_min_col - minor scale color for the warning zone
bar_col - the color of the bar in the middle
All colors are hex triplets - 0xff0000 is red, 0x00ff00 is
green, and 0x0000ff is blue.
@IMG battery.charge back_col=0xff00ff bar_col=0xaabbcc@
@IMG input.voltage ok_zone_maj_col=0x123456@
Insert the META header magic for refreshing the page if that
variable has been set by the browser. This needs to be in the
HEAD section of the page.
Expand the abbreviations in the ups.status variable - OL becomes
"On line", OB becomes "On battery", and so on.
Insert red, green, or yellow color triplets depending on the
severity of the current UPS status. Normal operations are
green, warnings like voltage trim/boost or "off" are yellow, and
other events like being on battery or having a low battery are
Insert the current value of the status variable varname on the
host being monitored, or "Not supported".
Inserts the current runtime, in hh:mm:ss format.
Use the Celsius scale for temperature data (default).
Use the Fahrenheit scale for temperature data.
Insert the UPS temperature in the current scale.
Insert the battery temperature in the current scale.
Obsoleted. Use IFBETWEEN instead (see example in upsstats.html).
Insert the version number of the software.
upsstats.cgi(8) will also open a file called upsstats-single.html if
you call it with "host=" set in the URL. That file uses the same rules
and techniques documented here.
