Gapcmon a Linux GUI monitor for APCUPSD A Gtk2/GLib2 GUI application used to monitor UPS devices controlled by the APCUPSD package.  The program uses the NIS interface from apcupsd to collect event and status information for display to the end-user.  Because of this great interface, this program can be executed on any OS supported machine and use the network socket interface to connect back to apcupsd.  Of course apcupsd must be compiled with nis support  (i.e. ./configure --enable-nis --enable-gapcmon ...).   The general design model for gapcmon assumes the user has one or more UPSs attached to one or more tcpip/hosts with network connectivity to/from the gapcmon workstation.  Gapcmon provides a Preferences panel to capture the hostname, port, and polling cycle for that UPS; along with an "enable" checkbox to indicate if the monitor for this configuration should be active.  Gapcmon collects status and event information for each enabled UPS configuration and presents it to the user via a Detailed Information window. GAPCMON is licensed under the GPL version 2. FEATURES FreeDesktop.org Spec for Notification Area Icons. Unlimited support for multiple UPSs. Historical Graph of five data points are charted.  A total of 40 points are maintained on the graph. The data points are LINEV, BATTV, BCHARGE, LOADPCT, and TIMELEFT. Clicking an notification icon will cause the information window for that monitor to become visible or be hidden, if its already visible. Monitor tooltips are available when hovering the mouse over the icon, and contain a quick summary of the ups status. Icons are dynamically added or removed when enabled in preferences. Icon changes to reflect the operational state of the UPS. where state is (online, onbattery, charging, not communicating, no cable) History graph supports popup tooltip for data point under the mouse pointer, showing dataseries name, color, time, and value. Configuration of the tcpi/ip hostname, tcp port number, and whether that monitor is currently enabled is provided via a central Preferences page. background thread for all network io to keep user interface responsive. Monitor information window { notebook layout with four tabs } History Historical Line Graph tracking VAC, battery charge, batt voltage, ups load, and time remaining.  Data collection for this chart is ten times the regular refresh time in seconds, and displays 40 collection cycles on screen.

Preferences configuration page allows user to specify the hostname, port, and refresh interval in seconds of the server/workstation running apcupsd with NIS configured. Glossary Quick help text About Program version and information panel Requirements     Gtk2/Glib-2.4 runtime support.     APCUPSD installed and configured to NIS support.         { get at http://apcupsd.sourceforge.net  }     * the following packages may need to be installed to build program and       for runtime of binaries on some platforms.     gapcmon            {gtk version 2.4 is minimum package level required}         glib-devel          gtk-devel         gconf2                                  Distribution Method     Source RPM    gapcmon-{version}-{release}.src.rpm     Binary RPM    gapcmon-{version}-{release}.i686.rpm     Source tar    gapcmon-{version}.tar.bz2 Install Info     Configure Source with     for gapcmon :             '# ./configure --prefix=/usr '                 Then compile with 'make clean all', then 'sudo make install'     Binary RPM install with this command 'rpm -ivh gapcmon-{version}-{release}.i686.rpm'     Both methods result in '/usr/bin/gapcmon'     being installed according to your system defaults for prefix.      Note: the configure step requires the parm 'prefix=/usr'. Instructions     1. look in gnome menus for the "Applications" group, then select "APCUPSD monitor"         - or enter '# gapcmon' on the command line.     2. To configure.         - select "Preferences" tab,         - enter hostname and port, choose refresh interval in seconds.         - be sure to click or unclick enable to activate the selection.     3. If you clicked the "enable" checkbox for a monitor, then its           information window is now active and recording status for that UPS. Known Bugs  NONE: ...
