This includes collecting the data, and displaying graphs. This page is closely related to APC SmartUps SU-700 - Linksys EA3500 - LuCI graphs, which is worth reviewing as well, especially if you run into difficulties. Note that the collected data will be lost after a reboot of the router. To save the data, you need to put it on an external device, like a USB flash drive. Connecting both the UPS and a flash drive to a USB hub, which is then connected to the router, works fine for me. Plug in UPS, and connect the cable from the UPS to the router USB port. This is a custom cable that comes with the UPS. in the router command line or LuCI web pages, install packages: apcupsd, collectd-mod-apcups and kmod-usb-hid for command line, the commands are: opkg update opkg install kmod-usb-hid opkg install apcupsd opkg install collectd-mod-apcups On the router command line, verify that the USB HID driver is installed and working with command and response: # ls -la /dev/usb crw------- 1 root root 180, 96 Jul 13 14:34 hiddev0 If you don't see a line for hiddev#, then something is wrong with the install of kmod-usb-hid. Resolve this, before proceeding. The next step is to customize the apcupsd config file. Details of the options can be found at http://www.apcupsd.org/manual/manual.html, in the section “Configuration Directive Reference”. On the router command line, go to the /etc/apcupsd directory, and edit it # cd /etc/apcupsd # vi use the dd command to delete all the lines in the file use the i command to set the VI editor into “insert” mode. Copy and paste this text into the editor: ## apcupsd.conf v1.1 ## UPSNAME myups UPSCABLE usb UPSTYPE usb DEVICE /dev/usb/hid/hiddev[0-15] LOCKFILE /var/lock ONBATTERYDELAY 6 BATTERYLEVEL 5 MINUTES 3 TIMEOUT 0 ANNOY 300 ANNOYDELAY 60 NOLOGON disable KILLDELAY 0 NETSERVER on NISIP 0.0.0.0 NISPORT 3551 EVENTSFILE /var/log/apcupsd.events # max kilobytes EVENTSFILEMAX 10 UPSCLASS standalone UPSMODE disable # ===== Configuration statements to control apcupsd system logging ======== # Time interval in seconds between writing the STATUS file; 0 disables STATTIME 0 # Location of STATUS file (written to only if STATTIME is non-zero) STATFILE /var/log/apcupsd.status LOGSTATS off # Time interval in seconds between writing the DATA records to # the log file. 0 disables.

Note the STATUS : ONLINE If you don't have “ONLINE”, then something is wrong Restart the LuCI statistics data collection: # /etc/init.d/luci_statistics restart In the router web interface, go to Statistics, Graphs, APC UPS You should see the graphs, with data starting on the right side. If not, wait a minute, refresh your browser and you should start to see data being written. Troubleshooting If you don't have APC UPS graphs at this point, here are some things to check: There should be a tab for APC UPS on the General Plugins page at:http://192.168.1.1:88/cgi-bin/luci/admin/statistics/collectd/general /var/etc/collectd.conf should have a section for apcups:LoadPlugin apcups <Plugin apcups> Host localhost Port "3551" </Plugin> If it does not, you can regenerate /var/etc/collectd.conf with this command: /usr/bin/stat-genconfig > /var/etc/collectd.conf If you still don't have APC UPS graphs, you may not have the patches that added luci-statistics support for the apcups plugin: https://github.com/openwrt/luci/pull/1227. The best fix for this is to upgrade to a version that does. This website uses cookies. By using the website, you agree with storing cookies on your computer.
