Zerto CSP Automated Billing (Call Home)

KB Number:

A CSP administrator needs to setup automated billing using the Zerto Callhome server

Every new CSP joining Zerto needs to setup an automated billing mechanism with Zerto. In order for it to function properly, certain configurations need to be in place.
This article elaborates on these configurations and provides additional details about the process. 


General Information:

Automated billing works in 2 separate flows working independently:

  1. Billing data is transmitted directly from the cloud ZVMs
  2. Billing data transmitted via the ZCM for all ZVMs connected to it

Zerto recommends both channels to be enabled to ensure redundancy. Temporary lack of connectivity will not result in loss of data. 

General requirement:

  • Each cloud ZVM must have a valid cloud license applied (including trial license). Without a valid cloud license, no billing data will be transmitted, not directly from the ZVM, nor through the ZCM (machine with NFR license doesn't transmit billing data). Multiple cloud licenses are not a problem. You can use any valid cloud license on any cloud ZVM, all of them will be consolidated to the same account.

Requirements for sending billing data:

  • Channel 1: Send data via the Zerto Cloud Manager (ZCM)

    • All cloud ZVMs must be connected to the ZCM (multiple ZCMs per account isn't a problem)

    • The ZCM must have internet access to Zerto’s Callhome server autologs.zerto.com over port 443.

    • The ZCM VM clock must be correct and set by network time protocol (NTP).

  • Channel 2: Send data directly via cloud ZVMs

    • All cloud ZVMs must have internet access to Zerto’s Call-Home server autologs.zerto.com over port 443.

    • Each cloud ZVM must have the “Enable Online Services” option enabled under its Support Settings section

      • Note: customer ZVMs in “to-cloud BC/DR” do not participate and do not need any internet access (this is due to the ZCM managing the Cloud ZVMs)

    • All cloud ZVMs VM clocks must be synchronized and set by network time protocol (NTP).

Additional details:

  • Data is sent securely (using https):

    • DNS - autologs.zerto.com

    • Port - 443 (standard https port)

  • The billing data is uploaded for processing on the 3rd day of each month. Zerto generates a report for a CSP based on the information received from all of their cloud ZVMs, aggregating data from all sites and removing duplicate data. The billing report (xlsx) is sent automatically to the CSP’s primary billing contact.
  • If no rejection received, CSPs are invoiced automatically according to the report.


  • Only cloud production ZVMs should have the cloud production license installed.

    • Test environments should be installed with Not-for-Resale (NFR) licenses, which can be obtained from your Zerto Account Manager.

    • Customer ZVMs in “to-cloud BC/DR” must not have access to the cloud production license key.

  • ZVM/ZCM internet connection through proxy is supported, however, connection via authenticated proxy is not supported. If a proxy is to be used, it must be set for the user running the ZVM service, which is "localservice" by default. To set a proxy for the localservice user, proceed as follows:

  • Open a console to the Windows machine running the ZVM.

  • Open an elevated command prompt.

  • Use the bitsadmin tool as follows, as per Microsoft's TechNet article (http://technet.microsoft.com/en-us/library/cc770473.aspx):

bitsadmin /Util /SetIEProxy localsystem MANUAL_PROXY <proxy list> <bypass list>

Ex: bitsadmin /Util /SetIEProxy localsystem MANUAL_PROXY NULL

Connectivity troubleshooting:

If automated billing reports aren’t being accurately generated or not generated at all, the CSP should use the following troubleshooting steps:

  • Confirm that the cloud production license is installed on all relevant cloud ZVMs

  • Verify that outbound internet access is available from each of the cloud ZVMs over port 443, specifically to the address autologs.zerto.com

    • Note: if applicable, the above address may be excluded from any proxy details for the servers.

  • Ensure that the “Enable Online Services” option is enabled under each ZVM’s Support Settings section

  • Ensure that it is possible to successfully navigate to the following URL from all cloud ZVMs: https://autologs.zerto.com/testpage

  • Ensure that ZVM and ZCM VMs’ clocks are synchronized, and set by NTP (time zone doesn't matter)
