UPSSTATS.CGI(8)

NAME

upsstats.cgi - Web-based UPS status viewer

SYNOPSIS

upsstats.cgi

Note	As a CGI program, this should be invoked through your web server. If you run it from the command line, it will either complain about unauthorized access or spew a bunch of HTML at you.

DESCRIPTION

upsstats.cgi uses template files to build web pages containing status information from UPS hardware. It can repeat sections of those template files to monitor several devices simultaneously, or focus on a single UPS.

These templates can also include references to upsimage.cgi(8) for graphical displays of battery charge levels, voltage readings, and the UPS load.

ACCESS CONTROL

upsstats will only talk to upsd(8) servers that have been defined in your hosts.conf(5). If it complains that "Access to that host is not authorized", check that file first.

TEMPLATES

The web page that is displayed is actually a template containing commands to upsstats which are replaced by status information.

The default file used for the overview of devices is upsstats.html.

When monitoring a single UPS, the file displayed is upsstats-single.html.

The format of these files, including the possible commands, is documented in upsstats.html(5).

JSON OUTPUT

In addition to processing HTML templates, upsstats.cgi can be invoked as a JSON API by adding the json parameter to the query string (e.g., ?json or &json).

When this parameter is present, the CGI script bypasses all HTML template parsing and instead returns a JSON object.

The structure of the JSON output depends on whether the host parameter is also provided:

Multi-host (Default): If no host parameter is specified, the script returns a single JSON object containing an "devices" key. This key holds an array, with each element in the array being a JSON object representing a monitored UPS.
Single-host Mode: If a host parameter is provided (e.g., ?host=myups@localhost&json), the script returns a single JSON object for that UPS (it will not be wrapped in an "devices" array).

In both modes, each UPS object includes:

host: The UPS identifier (e.g., "myups@localhost")
desc: The host description from ``hosts.conf``
status_raw: The raw status string (e.g., "OL")
status_parsed: An array of human-readable status strings (e.g., ["Online"])
vars: An object containing the full tree of all available variables for that UPS (e.g., "battery.charge": "100", "ups.model": "…")
