how to monitor APC 2200 UPS with apcupsd icinga/nagios

Posted on by

Download and install apcupsd-3.14.10-1.el4.i386.rpm package,
if you are using serial to usb cable you should have usbutils.i686 package.
Install also lm_sensors and net-snmp net-snmp-libs packages.
In this case, I made the physical connection with serial cable between CentOS linux box and UPS APC 2200.

[root@UPS1-2200-Linux ~]# dmesg | grep tty
console [tty0] enabled
serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
00:10: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A


[root@UPS1-2200-Linux ~]# chkconfig apcupsd on


[root@UPS1-2200-Linux ~]# /etc/init.d/apcupsd start

For a link to detailed USB trouble shooting information,
please see <http://www.apcupsd.com/support.html>.

We have to configure right settings in **/etc/apcupsd/apcupsd.conf**

We can monitor our ups status through web, it is simple


yum install httpd apcupsd-cgi


[root@UPS1-2200-Linux ~]# vim +577 /etc/httpd/conf/httpd.conf

ScriptAlias /cgi-bin/ “/var/www/apcupsd/”

#
