Working with Managed Servers

Image RemovedImage Added

The Managed Server page is where you can add a new server, view the list of existing servers, and view monitoring data on each server. From here, you may also access server settings and details for each server. 

...

The Managed Server Section List provides server and monitoring data for each managed DNS / DHCP / Backup server.

The list provides the following information:

...

Requests: Requests are the heartbeat notifications received in the last 2 minutes. Requests are sent every 30 seconds, so a display of 4 or 5 requests represents a satisfactory request connection, and the request bar will show in green. For any lower value, the color of the bar will show in red.

Monitor / Backup / DNS / Monitor / DHCP: The version of the component running. If the server is not running, no version will display.

Step 4: Service Settings

Here you can select which components to install linked to the current server. If you prefer not to add a service, both toggles may be disabled. 


Add DNS Service: Enable / Disable to add a DNS Managed Service link. Options include:

Max DNS Upgrade Version: Select either "latest", or select a specific version to install and not upgrade beyond, in case of known issues or incompatibility.


Add DHCP Service: Enable / Disable to add a DNS Managed Service link (Kea / MySQL DB). Multiple DHCP instances can connect to one database, organized as one parent with multiple children.

In ProVision, "1 database" = "1 dhcpmodule resource" , and only a "parent" DHCP can have address and credentials for the database. The children don't store any information about the database and the necessary data is taken from the parent; no "dhcpmodule resource" are created for the children.

Options include:

Max DHCP Upgrade Version: Select either "latest", or select a specific version to install and not upgrade beyond, in case of known issues or incompatibility.

Server Type: Select "Child" or "Parent".

    • Child: If "Child" is selected, then the parent server must be selected. On the managed server there will be an attribute to note that it will have DHCP component, but it would be a child one and which one is the parent. In this case the pv_mysql component is not installed as it is not needed - the DHCP will connect to another database
    • Parent (Default Configuration): By default, if "Parent" is selected then ProVision will set up pv_dhcp and pv_mysql components on the server and pv_dhcp will be configured to use this pv_mysql as database. The server will offer both IPv4 and IPv6 addresses.
    • Parent (Advanced Configuration): The main use case is when you don't want to put further load to the server by hosting the database or a database in a container might not perform good enough, you have this option to provide another MySQL instance. Using this the user can also modify the database name, user, password and if the server should serve IPv4, IPv6 or both. The user can also select the location of the database - local with pv_mysql component with the provided credentials or remote, which is completely remote database and no pv_mysql component will be set up. up.
