HOWTO: UPS with Gentoo Linux using NUT with MRTG Statistics
1.) Introduction
I use the Mustek Powermust USB 2000VA UPS
This UPS is supported by nut version >= 2.0.1
Important Notice:
I recommend you to use the "powermust" driver, as the "mustek" driver doesn't support 24V
UPSes and then you get as battery.value always 100% charge.
Besides, the "powermust" driver has more features.
2.) Install necessary packages
| Code: | | emerge nut apache2 mrtg |
Add apache to your default runlevel if you don't have done it yet:
| Code: | | rc-update add apache2 default |
Notice: If you also have a Mustek UPS it might be necessary to use the ~x86 version of nut
because at the moment the latest stable version of nut in the portage tree is version 2.0.0-r1
and this version of nut doesn't support the Mustek UPS series.
So you might do
| Code: | | echo "www-apps/nut ~x86" >> /etc/portage/package.keywords |
before merging nut!
If you don't have installed a cron daemon install one, e.g.: emerge vixie-cron
3.) Configure nut
Notice: The following configuration files are adapted for a Mustek UPS, if you use another
UPS you will need to change this files for your UPS!
My UPS is connected to COM1 (/dev/ttyS0).
The configuration files of nut are located under /etc/nut!
Index of ups.conf:
[server]
driver = powermust
port = /dev/ttyS0
Index of upsd.conf:
ACL all 0.0.0.0/0
ACL localhost 127.0.0.1/32
ACCEPT localhost
REJECT all
Index of upsd.users:
[admin]
password = yoursecretpassword
actions = SET
instcmds = ALL
[monuser]
password = yoursecretpassword
allowfrom = localhost markus
Index of upsmon.conf:
RUN_AS_USER root
MONITOR server@localhost 1 monuser yoursecretpassword master
MINSUPPLIES 1
SHUTDOWNCMD "/sbin/shutdown -h +0"
POLLFREQ 5
POLLFREQALERT 5
HOSTSYNC 15
DEADTIME 15
POWERDOWNFLAG /etc/killpower
RBWARNTIME 43200
NOCOMMWARNTIME 300
FINALDELAY 5
Index of upssched.conf:
CMDSCRIPT /usr/local/ups/bin/upssched-cmd
Start the daemons an add them to the default runlevel:
| Code: | /etc/init.d/upsd start
/etc.init.d/upsmon start
rc-update add upsd default
rc-update add upsmon default |
Test if you are able to check the status of your UPS:
| Code: | | upsc server@localhost |
You should get a output like this:
battery.charge: 75.0
battery.voltage: 25.4
battery.voltage.nominal: 24.0
driver.name: powermust
driver.parameter.port: /dev/ttyS0
driver.version: 2.0.2
driver.version.internal: 1.1
input.voltage: 228.6
input.voltage.fault: 228.1
input.voltage.maximum: 234.4
input.voltage.minimum: 227.6
output.frequency: 50.1
output.voltage: 225.7
output.voltage.target.battery: 220.0
ups.delay.shutdown: 2
ups.delay.start: 3
ups.load: 9.0
ups.mfr: Mustek
ups.model: PowerMust
ups.serial: unknown
ups.status: OL
Notice: If your ouput is different you might have to need change your mrtg config files - see next chapter!
4.) Configure MRTG
Create the directory /etc/mrtg/ups/:
| Code: | | mkdirhier /etc/mrtg/ups/ |
Download this tar archive and extract it in this directory: index.tar
| Code: | cd /etc/mrtg/ups/
tar xvf index.tar |
Make all *.sh-files executable:
You might have to adapt this files for your system!
Create the index.html file:
| Code: | /usr/bin/indexmaker \
--output=/var/www/localhost/htdocs/ups/index.html \
--title="USV Status" --sort=name --enumerate \
/etc/mrtg/ups/voltage.cfg \
/etc/mrtg/ups/batteryvoltage.cfg \
/etc/mrtg/ups/batterycharge.cfg \
/etc/mrtg/ups/load.cfg \
/etc/mrtg/ups/frequency.cfg \
/etc/mrtg/ups/status.cfg \ |
Create the directory /etc/cron.mrtg an create a file named ups.sh with this content...
#!/bin/sh
/usr/bin/mrtg /etc/mrtg/ups/voltage.cfg
/usr/bin/mrtg /etc/mrtg/ups/batteryvoltage.cfg
/usr/bin/mrtg /etc/mrtg/ups/batterycharge.cfg
/usr/bin/mrtg /etc/mrtg/ups/status.cfg
/usr/bin/mrtg /etc/mrtg/ups/load.cfg
/usr/bin/mrtg /etc/mrtg/ups/frequency.cfg
... and make it executable:
Execute this script (/etc/cron.mrtg/ups.sh) at least three times (don't care about the warnings)!
Run the command crontab -e and add this line to update the statistics every 5 minutes:
*/5 * * * * /bin/run-parts /etc/cron.mrtg 1> /dev/null
5.) Testing
Now open your web browser and open the page http://yourserver/ups
Your should now see your statistics, here a picture of mine: http://www.layr.at/markus/images/linux/ups/ups.jpg
6.) Sending an email when UPS is offline (Optitional)
I use ssmtp to send my an email via my yahoo account to an another email-address of an ISP
which allows forwarding emails to sms, so I get a sms to my mobile phone when the UPS is offine.
Configure ssmtp (/etc/ssmtp/ssmtp.conf):
root=youraddress@isp.com
mailhub=smtp.mail.yahoo.com
rewriteDomain=yahoo.de
FromLineOverride=YES
Create a file named upsmail.sh in your home directory (root) with this content...
if [ "`upsc server@localhost ups.status|grep OL`" == "" ]
then
echo "Subject: USV OFFLINE" > /tmp/usv.msg
echo "" >> /tmp/usv.msg
upsc server@localhost |grep "battery.charge" >> /tmp/usv.msg
upsc server@localhost |grep "battery.voltage:" >> /tmp/usv.msg
upsc server@localhost |grep "input.voltage" |grep "input.voltage:" >> /tmp/usv.msg
upsc server@localhost |grep "output.voltage" |grep "output.voltage:" >> /tmp/usv.msg
upsc server@localhost |grep "ups.status" >> /tmp/usv.msg
cat /tmp/usv.msg | /usr/sbin/ssmtp -au yourusername -ap yourpassword tothisaddress@isp.com
fi
... and make it executable: | Code: | | chmod 755 upsmail.sh |
Run the command
and add this line to executes this script every 5 minutes:
*/5 * * * * /root/usvmail.sh
Now you should get an email if your UPS is offline, I use the sms.at gateway to send my this emails as sms.

Great Howto!!!
Works fine.
But it seems that the tar-Archive is corrupt. The file batterycharge.cfg inside looks like an archive...
Could you post the content of the file? Or please correct the archive.
Thx,
Nighty

Hello,
I know that's a verry old threat, but anyone have the archive . Link is dead.
Or just a model of config.
Thanks you very much. |

Hello,
I fixed the link.
The name of the driver has changed to megatec (I use sys-power/nut-2.0.5-r2 now). |

Hi sbranz,
You mean that you want the PC to start up after the ups had shutdown and when the line power is restored.
Yes this is possible. You set it in the bios of your pc.
You find someting like "Power State After AC Loss" in the settings.
And you may have "On", "Off", "Last State"
Set it to "last state" because if you have it off and don't want it to start, setting it to
"on" would start the PC after a power loss.
This info is in the doc's of nut also.
But you must have setup nut right so it does a shutdown return on power loss.
Regards
Kjell |
