3.6 Web-based monitoring<br />
• Comes stock with CGI-based web interface tools for <strong>UPS</strong> monitoring and management, including graphical status displays.<br />
• Custom status web pages may be generated with the CGI programs, since they use templates to create the pages. This allows<br />
you to have status pages which fit the look and feel of the rest of your site.<br />
3.7 Free software<br />
• That’s free beer and free speech. Licensed under the GNU General Public License version 2 or later.<br />
• Know your systems - all source code is available for inspection, so there are no mysteries or secrets in your critical monitoring<br />
tools.<br />
3.8 <strong>UPS</strong> management and control<br />
• Writable variables may be edited on higher end equipment for local customization<br />
• Status monitoring can generate notifications (email/pager/SMS/. . . ) on alert conditions<br />
• Alert notices may be dampened to only trigger after a condition persists. This avoids the usual pager meltdown when something<br />
happens and no delay is used.<br />
• Maintenance actions such as battery runtime calibration are available where supported by the <strong>UPS</strong> hardware.<br />
• Power statistics can be logged in custom formats for later retrieval and analysis<br />
• All drivers are started and stopped with one common program. Starting one is as easy as starting ten: upsdrvctl start.<br />
• Shutdowns and other procedures may be tested without stressing actual <strong>UPS</strong> hardware by simulating status values with the<br />
dummy-ups pseudo-driver. Anything which can happen in a driver can be replicated with dummy-ups.<br />
3.9 Monitoring diagrams<br />
These are the most common situations for monitoring <strong>UPS</strong> hardware. Other ways are possible, but they are mostly variants on<br />
these four.<br />
Note<br />
these examples show serial communications for simplicity, but USB or SNMP or any other monitoring is also possible.<br />
3.9.1 "Simple" configuration<br />
One <strong>UPS</strong>, one computer. This is also known as "Standalone" configuration.<br />
This is the configuration that most users will use. You need at least a driver, upsd, and upsmon running.
