==Setting UPS Variables==
In order to set UPS variables it is necessary to have enabled a user with administrative privileges as above first.
In the examples below, it is assumed your UPS name is '''UPS''', that it is local, that the administrative user is '''admin''' and password '''admin'''. You can verify your UPS name via:
upsc -l
To view a complete list of the UPS variables, both informational and modifiable
upsc UPS
To determine the modifiable variables for your UPS, their current settings and their available setting values execute the command:
upsrw UPS
You can now modify the variables you wish using a command similar to the following (Note the order of the arguments is important, and you may need quotes around the value being set, "20"):
upsrw -s battery.charge.low=20 -u admin -p admin UPS
Where the value after '''-s''' should be one of the parameters identified by the '''upsrw ups''' command. You can of course verify your changes using
upsrw UPS
or
upsc UPS
After you are done, clean up by disabling the '''upsd''' administrative user '''admin''':
{{Warning box|Make sure you understand the meaning or the UPS variables and their available setting options. Verify that your changes meet your intended behaviour!}}
More information on upsrw can be found at:
- Manual page: man upsrw
====Issuing UPS Commands====
In order to issue UPS commands it is necessary to have enabled a user with administrative privileges as above first.
In the examples below, it is assumed your UPS name is '''UPS''', that it is local, that the administrative user is '''admin''' and password '''admin'''. You can verify your UPS name via:
upsc -l
To view a complete list of available commands for your UPS:
upscmd -l UPS
You can now issue a command to the UPS with similar to the following:
upscmd -u admin -p admin UPS test.battery.start
Where the command '''test.battery.start''' is a valid command for your UPS as previously determined by '''upscmd -l UPS'''. Depending upon the command issued you may get broadcast messages and emails relating to and confirming what the UPS is doing.
After you are done, clean up by disabling the '''upsd''' administrative user '''admin''':
{{Warning box|Before issuing any commands verify what they do for your particular UPS via the relevant documentation and ensure that the command meets your intended behavioural requirement!
Issuing commands could shutdown your server unexpectedly!}}

===UPS Variables and Commands===
In some cases you may wish to modify variables on the actual UPS such as the Low Charge/LOWBATTERY setting. This requires the use of the '''upsrw''' command and UPS administrative privileges.
You may also want to control the UPS directly from the command line by issuing UPS commands. This requires use of the '''upscmd''' command and UPS administrative privileges.
{{Warning box|In general, the UPS data should be left protected and changes to it or issuing of commands well thought out. If you wish to make data changes or issue commands then the administrative privileges can be enabled as below and should then be disabled.}}
====UPS Administrative Privileges====
You should check your new password ( AdminPass ) to run '''upserw''' & '''upscmd'''. Of course, you could change your password for a easier one to use.

The access of the ups is controled by database properties, three possible choice.
==== UPS access ====
localhost: the ups access is only from the local machine ( UPS master ).
private: the ups is accessable from your local network as per define in server-manager panel.
The access of the ups is controled by database properties. The default propertie is set to localhost and give permission to run '''upsrw''' & '''upscmd''' from localhost only if administrative privileges is set to enabled as above. No slave ups could be connected in this mode. Three choices is available to set access.
public:
* localhost: the ups access is only from the local machine ( UPS master ).
* private: the ups access is from your local machine and local network as per define in server-manager panel.
* public: the ups access is similar to localhost.
To set access properties in the database ( example: localhost )

/usr/sbin/upsd -c reload
In localhost or public mode ( no remote access ), access to your ups is ( UPS name is '''UPS''' )
UPS@localhost
In private mode, access to your ups is ( UPS name is '''UPS''' )
In order to set UPS variables it is necessary to have enabled a user with administrative privileges as above first.
UPS@localhost or UPS@192.168.1.1 ( ups master IP )
slave ups get access with UPS@192.168.1.1 ( ups master IP )
==Setting UPS Variables==
In order to set UPS variables it is necessary to have enabled the administrative privileges as above first and you get the possibility to run command from slave ups if access is set to private as above.

=Configure Nut-cgi Monitor Scripts=
The nut-cgi rpm contains scripts that can be run via the webserver to monitor the UPS(s).
===Dowload and install===
You have to enable the '''[[epel]]''' repositories.
yum install --enablerepo=epel nut-cgi
Edit file /etc/ups/hosts.conf and add.
MONITOR UPS@localhost "local UPS"
The nut-cgi rpm contains three cgi scripts. The rpm does not install them correctly for SME however so the following modifications are needed.
mkdir -p /opt/nut-cgi-bin
chown root:www /opt/nut-cgi-bin
mv /var/www/nut-cgi-bin/upsstats.cgi /opt/nut-cgi-bin
mv /var/www/nut-cgi-bin/upsset.cgi /opt/nut-cgi-bin
mv /var/www/nut-cgi-bin/upsimage.cgi /opt/nut-cgi-bin
chown root:www /opt/nut-cgi-bin/*
chmod 750 /opt/nut-cgi-bin/*
mkdir -p /etc/e-smith/templates-custom/etc/httpd/conf/httpd.conf
cd /etc/e-smith/templates-custom/etc/httpd/conf/httpd.conf
Now edit and create a new file 92nutupscmon with the following content
{
$OUT = "";
my $allow = 'all';
my $pass = '0';
my $satisfy = 'all';
my $name = $nut{'Name'} || 'NUT UPS Daemon Monitoring';

Configure databases and expand the template

/sbin/e-smith/expand-template /etc/httpd/conf/httpd.conf
{{Note box|The above sets access to the scripts to ''local'' ip addresses only. See the [[Web_Application_RPM#New_DB_settings]] for further info and settings}}
Restart the web server
sv t httpd-e-smith
===Usage of Nut-cgi Scripts===
Now go to http://yourdomain.tld/nut to see the statistics and information for the UPS at localhost.
By editing /etc/ups/hosts.conf and adding additional network UPS details, nut-cgi can be used to monitor more than one UPS. By the modification above, only the localhost is monitored.
=Aditional Information=
There are template fragments in /etc/e-smith/templates/etc/ups that control the config files located in /etc/ups. The default settings should be OK for most situations.
