UPSSTATS.HTML(5)

NAME

upsstats.html - HTML template for web-based Network UPS Tools upsstats

DESCRIPTION

This file, and a similarly structured upsstats-single.html for certain use-cases, are used by upsstats.cgi(8) to generate NUT CGI status pages. Certain commands are recognized, and will be replaced with various status elements on the fly.

As a bit of a safety check, the file must start with @NUT_UPSSTATS_TEMPLATE@ command.

For details about configuring some popular web servers to run NUT CGI programs, please see the upsset.conf(5) page.

Note

This template file should be placed in the NUT configuration location. If you use a dedicated copy of that directory or one not discovered by the binaries relocated into your web server’s cgi-bin locations (such as with NUT for Windows builds, defaulting to seek in locations relative to each binary), consider exporting the NUT_CONFPATH environment variable from the web server.

Note

On platforms with required program file name extensions, like Windows, you may have to use e.g. a *.cgi.exe extension for the programs in HTML template files (UPSSTATSPATH, UPSIMAGEPATH).

FORMATTING

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 HTML entity @ to prevent it from being treated as a start character.

BLOCK CONTROL

Some commands begin blocks — sections of the template that will be included, excluded, or repeated depending on certain parameters.

BLOCK CONTROL - ITERATION

@FOREACHUPS@

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.

@ENDFOR@

Ends a FOREACHUPS block.

BLOCK CONTROL - MATCHING SPECIFIC CASES

@IFSUPP var@*

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 matches value.

Note
You can use @IFEQ upsstats.use_celsius (0|1)@ to check for the current setting of @TEMPC@ or @TEMPF@ toggle.

@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.

@ENDIF@

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).

@IFSUPP ambient.humidity@
@IFSUPP ambient.temperature@
This UPS knows both ambient temperature and humidity.
@ELSE@
@IFSUPP ambient.humidity@
This UPS only knows ambient humidity.
@ELSE@
@IFSUPP ambient.temperature@
This UPS only knows ambient temperature.
@ELSE@
This UPS knows nothing, how annoying.
@ENDIF@

OTHER COMMANDS

@NUT_UPSSTATS_TEMPLATE [args]@

The template file MUST start exactly with @NUT_UPSSTATS_TEMPLATE@ or @NUT_UPSSTATS_TEMPLATE Some text@ so that upsstats.cgi(8) is not coerced into showing arbitrary files.

Currently the command and its arguments are otherwise ignored; templates shipped with NUT use the argument values "default" and "single" effectively as a comment for debugging/troubleshooting.

@UPSSTATSPATH filename@

URI to the upsstats.cgi(8) program placed into HTML references. Default is the program’s name, making it a link relative to the currently displayed page in the browser.

May have to include the platform-specific program file name extension, like @UPSSTATSPATH upsstats.cgi.exe@

@UPSIMAGEPATH filename@

URI to the upsimage.cgi(8) program placed into HTML references. Default is the program’s name, making it a link relative to the currently displayed page in the browser.

May have to include the platform-specific program file name extension, like @UPSIMAGEPATH upsimage.cgi.exe@

@AMBTEMP@

Insert the ambient temperature in the current temperature scale.

@DATE format@

Insert the current date and time. The format string is passed to strftime, so almost anything is possible. See strftime(3) for possible values.

@DEGREES@

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 myups@localhost.

@HOSTDESC@

Insert the host’s description from hosts.conf(5).

@HOSTLINK@

Insert a HTML link to upsstats.cgi(8) with the "host" variable set to the current UPS. This is only useful within a FOREACHUPS block.

@TREELINK [Link text]@

Insert a HTML link to upsstats.cgi(8) with the "host" variable set to the current UPS and "treemode" enabled to show all data points as an HTML page. This is primarily useful within a FOREACHUPS block, but also as an upsstats-single.html footer. If some "Link text" is not provided, it defaults to "All data".

@TREELINK_JSON [Link text]@

Insert a HTML link to upsstats.cgi(8) with the "host" variable set to the current UPS and "treemode" enabled to show all data points as a JSON document. This is primarily useful within a FOREACHUPS block, but also as an upsstats-single.html footer. If some "Link text" is not provided, it defaults to "JSON".

@IMG varname @

Insert an IMG SRC to upsimage.cgi(8) for one of these status variables:

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(8). 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

ok_zone_min_col

minor scale color for the normal ("ok") zone

neutral_zone_maj_col

major scale color for the neutral zone

neutral_zone_min_col

minor scale color for the neutral zone

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 — e.g. 0xff0000 is red, 0x00ff00 is green, and 0x0000ff is blue.

Examples:

@IMG battery.charge@
@IMG battery.charge back_col=0xff00ff bar_col=0xaabbcc@
@IMG input.voltage ok_zone_maj_col=0x123456@

@REFRESH@

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.

@STATUS separator@, @STATUS@

Expand the abbreviations in the ups.status variable — OL becomes "On line", OB becomes "On battery", and so on. Reported values are separated by the specified optional separator (<br/> if not specified), which starts at the next character after the "STATUS<space>" (e.g. a @STATUS @ directive might be used to avoid any separation, or @STATUS @ to separate by spaces.

@STATUSCOLOR@

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 red.

@VAR varname@

Insert the current value of the status variable varname on the host being monitored, or "Not supported".

@RUNTIME@

Inserts the current runtime, in hh:mm:ss format.

@TEMPC@

Use the Celsius scale for temperature data (default).

@TEMPF@

Use the Fahrenheit scale for temperature data.

@UPSTEMP@

Insert the UPS temperature in the current scale.

@BATTTEMP@

Insert the battery temperature in the current scale.

@UTILITYCOLOR@

Obsoleted. Use IFBETWEEN instead (see example in upsstats.html).

@VERSION@

Insert the version number of the software.

OTHER TEMPLATES

upsstats.cgi(8) will also open a file called upsstats-single.html if you call it with host= set in the query URL. That file uses the same rules and techniques as documented here.
