Vunetrix Manual: Add a Device

Note: This documentation refers to the Vunetrix System Administrator user accessing the Ajax interface on a master node. For other user accounts, interfaces, or nodes, not all of the options might be available as described. When using a cluster installation, failover nodes are read-only by default.

To manually add a device, select Devices | Add Device from the main menu. An assistant will appear, leading you through two steps. For faster setup, you can select Add Device... in the context menu of a group to which you want to add the new device. This will skip step 1 and lead you directly to step 2.

  • Step 1
    Please choose a group you want to add the new device to. Click on Continue.

Add Device Settings

Device Name and Address

Device Name

Enter a meaningful name to identify the device. The name will be shown by default in the device tree and in all alarms.

IP Version

Define which IP protocol Vunetrix will use to connect to this device. The setting is valid for all sensors created on this device. Choose between:

  • Connect using IPv4: Use IP version 4 for all requests to this device.
  • Connect using IPv6: Use IP version 6 for all requests to this device.

IP Address/DNS Name

Enter the IP address (either v4 or v6, depending on your selection above) or DNS name for the device. Most sensors created on this device will inherit this setting and they will try to connect to this address for monitoring. Note: There are some sensor types that still have their own setting for IP address/DNS name. Those sensors will use their own settings.

Tags

Enter one or more tags; confirm each tag by hitting space, comma, or enter key. You can use tags to group sensors and use tag-filtered views later on. Tags are not case sensitive. Tags are automatically inherited.

Device Icon

Choose a device icon from the list. It will be shown in the device tree.

Device Type

Sensor Management

Select which type of auto-discovery you would like to perform for this device. Choose between:

  • Manual (no auto-discovery): Do not auto-discover any sensors, but only add sensors manually.
  • Automatic device identification (standard, recommended): Use a small set of auto-discovery templates. This will scan your LAN and usually create a view standard sensors on your device.
  • Automatic device identification (detailed, may create many sensors: Use an extended set of auto-discovery templates. This will scan your LAN and usually create many sensors on your device.
  • Automatic sensor creation using specific device templates: Use specific auto-discovery templates only. Please select templates below. This will scan your LAN and add sensors defined in the template.

Discovery Schedule

This option is only visible if one of the auto-discovery options is selected above. Define when the auto-discovery will be run. Choose between:

This field is only visible if password login is selected above. Enter a password for the Linux access via SSH and WBEM. Usually, you will use credentials with administrator privileges.

Private Key

This field is only visible if private key login is selected above. Paste a private key into the field (OpenSSH format, unencrypted). Usually, you will use credentials with administrator privileges. Note: If you do not insert a private key for the first time, but change the private key, you need to restart your Vunetrix core server service in order for the private key change to take effect! For details, please see Monitoring via SSH.

For WBEM Use Protocol

Define the protocol that will be used for WBEM. This setting is only relevant when using WBEM sensors. Choose between:

  • HTTP: Use an unencrypted connection for WBEM.
  • HTTPS: Use an SSL-encrypted connection for WBEM.

For WBEM Use Port

Define the port that will be used for WBEM. This setting is only relevant when using WBEM sensors. Choose between:

  • Set automatically (port 5988 or 5989): Use one of the standard ports, depending on whether unencrypted or encrypted connection is chosen above.
  • Set manually: Use a custom port. Define below.

WBEM Port

This setting is only visible if manual port selection is enabled above. Enter the WBEM port number.

SSH Port

Define the port number which will be used for SSH connections. Note: By default, this setting is automatically used for all SSH sensors, unless you define a different port number in the sensor settings.

SSH Rights Elevation

Define with which rights the command will be executed on the target system. Choose between:

  • Run the command as the user connecting (default): Use the rights of the user who establishes the SSH connection.
  • Run the command as another user using 'sudo': Use the rights of another user, for example, the administrator.
  • Run the command as another user using 'su': Use the rights of another target user.

Target Username

This field is only visible if sudo or su is enabled above. Enter a username to run the specified command as another user than root. If you leave this field empty, the command will be run as root. Ensure that you set the Linux password even you use a public/private key for authentication.  This is not necessary if the user is allowed to execute the command without a password.

Password Target User

This field is only visible if su is enabled above. Enter the password for the specified target user.

Credentials for VMware/XenServer

User

Enter a login name for access to VMware and XEN servers. Usually, you will use credentials with administrator privileges.

Password

Enter a password for access to VMware and XEN servers. Usually, you will use credentials with administrator privileges.

VMware Protocol

Define the protocol used for the connection to VMware and XenServer. Choose between:

  • HTTPS (recommended): Use an SSL-encrypted connection to VMware and XenServers.
  • HTTP: Use an unencrypted connection to VMware and XenServers.

Credentials for SNMP Devices

SNMP Version

Select the SNMP version that will be used for device connection. Choose between:

  • v1: Use the simple standard v1 protocol for SNMP connections. This protocol only offers clear-text data transmission, but it is usually supported by all devices.
  • v2c: Use the more advanced v2c protocol for SNMP connections. Data is still transferred as clear-text, but it supports 64-bit counters.
  • v3: Use the latest v3 protocol for SNMP connections. It provides secure authentication and data encryption.

Note for SNMP v3: Due to internal limitations you can only monitor a limited number of sensors per second using SNMP v3. The limit is somewhere between 1 and 50 sensors per second (depending on the SNMP latency of your network). This means that using an interval of 60 seconds you are limited to between 60 and 3000 SNMP v3 sensors for each probe. If you experience an increased "Interval Delay" or "Open Requests" reading of the probe health sensor, you need to distribute the load over multiple probes. SNMP v1 and v2 do not have this limitation.

Community String

This setting is only visible if SNMP version v1 or v2c are enabled above. Enter the community string of your devices. This is a kind of "clear-text password" used for simple authentication. We recommend using the default value.

Authentication Type

This setting is only visible if SNMP version v3 is enabled above. Choose between:

  • MD5: Use Message-Digest Algorithm 5 (MD5) for authentication.
  • SHA: Use Secure Hash Algorithm (SHA) for authentication.

The chosen type has to match the authentication type of your device.

Note: If you do not want to use authentication, but you need SNMP v3, for example, because your device requires context, you can leave the field password empty. In this case, SNMP_SEC_LEVEL_NOAUTH will be used and authentication will be deactivated entirely.

User

This setting is only visible if SNMP version v3 is enabled above. Enter a username for secure authentication. This value has to match the username of your device.

Password

This setting is only visible if SNMP version v3 is enabled above. Enter a password for secure authentication. This value has to match the password of your device.

Encryption Type

This setting is only visible if SNMP version v3 is enabled above. Select an encryption type. Choose between:

  • DES: Use Data Encryption Standard (DES) as encryption algorithm.
  • AES: Use Advanced Encryption Standard (AES) as encryption algorithm.

The chosen type has to match the encryption type of your device.

Data Encryption Key

This setting is only visible if SNMP version v3 is enabled above. Enter an encryption key here. If you provide a key in this field, SNMP data packets will be encrypted using the encryption algorithm selected above, providing increased security. The provided key here has to match the encryption key of your device. Note: If the key entered in this field does not match the key configured in the target SNMP device, you will not get an error message! Please enter a string or leave the field empty.

Context Name

This setting is only visible if SNMP version v3 is enabled above. Enter a context name only if it is required by the configuration of the device. Context is a collection of management information accessible by an SNMP device. Please enter a string.

SNMP Port

Enter the port used for SNMP communication. We recommend using the default value.

SNMP Timeout (sec.)

Enter a timeout in seconds for the request. If the reply takes longer than this value the request is aborted and an error message is triggered.

Access Rights

User Group Access

Define which user group(s) will have access to the object you're editing. A table with user groups and right is shown; it contains all user groups from your setup. For each user group you can choose from the following access rights:

  • Inherited: Use the settings of the parent object.
  • None: Users in this group cannot see or edit the object. The object does not show up in lists and in the device tree. Exception: If a child object is visible to the user, the object is visible in the device tree, though not accessible.
  • Read: Users in this group can see the object and review its monitoring results.
  • Write: Users in this group can see the object, review its monitoring results, and edit the object's settings. They cannot edit access rights settings.
  • Full: Users in this group can see the object, review its monitoring results, edit the object's settings, and edit access rights settings.

You can create new user groups in the System Administration—User Groups settings. To automatically set all objects further down in the hierarchy to inherit this object's access rights, set a check mark for the Revert children's access rights to inherited option.

For more details about access rights, please see section User Access Rights.

Click on the Continue button to store your settings. If you change tabs or use the main menu, all changes to the settings will be lost!
