Modifying an Sensor

To modify an sensor, you must have the administrative privileges on the sensor you would like to modify. The following tables describe the fields you may edit as an administrator.

To modify an App:

Click the "Admin" tab.
Click the "Sensor Admin" tab.
If there are Apps available to modify, you will see a table of Apps. Click on the name of the Sensor you would like to modify.
Click the "Sensor Edit" tab.
You will now see the fields you may modify, and the current value for each. Make the necessary changes to any or all of the fields.
Click the "Modify App" button. A success or failure message will display on the page.

Mandatory Fields

Field Name	Description
Sensor Name	The name used to describe the sensor within SCInterface.
Address	The hostname or IP address of the machine on which the sensor resides. Must match the output of the hostname command on that machine.
Port	The port on which the sensor will be available for connections.
SC Host	The name of the SC that will control this sensor. This SC must reside on the same machine as the sensor.
SConnector Type	The SConnector type of the new sensor.
Base Path	The path to the directory where the sensor executable resides (such as"/home/appUser/"). If the directory does not exist and you would like to create it, check the create checkbox.
Owner	The name of the owner for the sensor. The owner will receive support tickets submitted for the sensor.
System User	The username of the user on the machine where the sensor resides who will run the sensor. If the user does not exist and you would like to create them, check the create checkbox. By default, this user's home directory will become the base path.
Status Cache Interval:	When SCInterface caches the status for a particular sensor, this is the interval that the 'status' macro values are expired and the sensor data needs to be updated. Set this value to '0' (without quotes) to disable caching for this sensor.
Disabled	Toggle this on to disable the SC and all sensors associated with this SC

Optional Fields

Some of these fields may not be present within your interface. This can depend on the macro or command actually existing for the sensor or SC and if the sensor or SC is running or not.

Field Name	Description
Host Startup Action	Choose a command that the SC will run for this sensor when the SC is (re)started.
Scan Port	For sensors that have a second port that monitoring programs, this is the value for that port.
Shell	This is the default system 'shell' that this sensor will run under when executing the sensor. This is primarily used for Linux/BSD/Unix sensors only.
MD5 Checksums	The output of an md5sum command. SCInterface will check to see that it is correct. Example:"11f7af1d55c5922e99615816fe2fcb0e install.sh 036cb89b14f5dcc0e97dbbb148003da7 libpqxx-2.4.2-1.i586.rpm" would allow you to verify the checksums of install.sh and libpqxx-2.4.2-1.i586.rpm.
Default Startup Parameters	These are the default parameters that are accessible from the configuration section of the web interface.
Alter Config Options	The Alter Config section provides a means to easily modify common parameters stored in configuration files. The 'Alter Config' settings can be changed by a normal user under the config interface for the sensor. Click on the 'Configuration' tab and then select 'Alter Config' tab.
Forced Params	The parameters that will always be sent at execution time.
Abs Path to Exe	The location of the actual program executable. Check the create symbolic link checkbox to create a symbolic link to the executable in the sensor's base directory.
Config Dir	The path to the directory which contains configuration files. Click the create symbolic link checkbox to create a symbolic link to the executable in the sensor's base directory.
Install Files and Default Config Settings	Choose this option when adding a new sensor to install the sensor dependencies from the SCInterface installer repository. If this field is disabled, the sensor dependencies can be installed manually from the sensors config section under the 'Overview' tab or under the 'Commands' tab (select the 'Install') command to (re)install the sensor dependencies.
Start after install	Choose this option if you wish for the sensor to automatically start after installing the dependencies.
After Adding	The page to bring up after this sensor has been added. You may either view the Admin page for the sensor, or add another sensor.
