APC SmartUPS daemon for Linux
Posted by Planet Malaysia on August 30, 2006
Recently we bought a new APC UPS SmartUPS 2200. Originally APC UPS came together with PowerChute Business Edition Basic software.
Basically you have to install “The PowerChute Business Edition Agent” on the Linux machine which is compatible with Red Hat 7.3, Red Hat 8.0, Red Hat 9.0, SuSE 8.0, SuSE 8.1, SuSE 8.2, Turbolinux 7.0, and Turbolinux 8.0 according to the readme file in the CD.
Launch the PowerChute Business Edition for Linux installer by entering the absolute path to the pbe_agent_redhat_jvm.bin file.
/media/cdrom/Linux/pbe_agent_linux_jvm.binAn RPM package of the PowerChute Business Edition Agent for Linux is also available.
rpm ivh /media/cdrom/Linux/pbeagent-xxx.i386.rpm
Once the powerchute business edition agent has been installed, you must configure the Agent for login information and the UPS type. This is handled by running the config.sh script located within the PowerChute Business Edition installation directory.
This utility allows you to create an account name and password, and to configure the UPS by entering the communication type and communication port. After completing the configuration, you may start the PowerChute Business Edition Agent.
But I found this ’solution’ is not good in Linux environment because you have to install PowerChute Business Edition Server & Console for allow connect to any Linux Server installed with PowerChute Business Edition agent.
Check here for more screen shot.
Anyway, there is an open source of APC UPS daemon for Linux release under GPL license.
Apcupsd can be used for power mangement and controlling most of APC’s UPS models on Unix and Windows machines. Apcupsd works with most of APC’s Smart-UPS models as well as most simple signalling models such a Back-UPS, and BackUPS-Office. During a power failure, apcupsd will inform the users about the power failure and that a shutdown may occur. If power is not restored, a system shutdown will follow when the battery is exhausted, a timeout (seconds) expires, or runtime expires based on internal APC calculations determined by power consumption rates.
There are 3 types of configuration:
1)Standalone Configuration
2)Typical Master/Slave Configuration
3)Multi-UPS Configuration
The configuration here is for Typical Master/Slave Configuration ( few servers connect to 1 physical UPS & only master server connect with serial cable)
Download latest apcupsd from SourceForge
Installation from Source:
Run ./configure --enable-master-slave --enable-cgi
make
make install
A Simple Master Configuration
vi /etc/apcupsd/apcupsd.conf
UPSCABLE smart
UPSTYPE apcsmart
DEVICE /dev/ttyS0
LOCKFILE /var/lock
UPSCLASS netmaster
UPSMODE net
NETTIME 10
NETPORT 6666
SLAVE slave1.yournetwork.com
SLAVE slave2.yournetwork.com
A Simple Slave Configuration
vi /etc/apcupsd/apcupsd.conf
UPSCABLE ether
UPSTYPE apcsmart
LOCKFILE /var/lock
UPSCLASS netslave
UPSMODE net
NETPORT 6666
MASTER master.mynetwork.com
Start the apcupsd service
/etc/init.d/apcupsd start OR service apcupsd start
The main difference from the master configuration is that you have specified UPSCABLE ether and UPSCLASS netslave.
In this configuration, the shutdown will be initiated by the master. It is also possible to specify BATTERYLEVEL, MINUTES, and TIMEOUT configuration directives in the Slave machine that will cause the slave to shutdown before the master. This can often be useful if the slave is less important than the master and you wish to reduce battery power consumption so that the master can remain up longer during a power outage.

Setting up and Testing the CGI Programs
Before using multimon and the other CGI programs, first ensure that apcupsd is configured to run the Network Information Server. This is done by setting NETSERVER on in /etc/apcupsd/apcupsd.conf.
Edit the hosts file /etc/apcupsd/hosts.conf & add the name of the hosts you want to monitor and a label string for them.
MONITOR 127.0.0.1 “master.yournetwork.com”
MONITOR 192.168.1.2 “slave1.yournetwork.com”
MONITOR 192.168.1.3 “slave2.yournetwork.com”
Copy “multimon.cgi “, “upsimage.cgi”, “upsfstats.cgi”, “upsstats.cgi” from /etc/apcupsd to /var/www/cgi-bin/
Restart Apache.
