Limitation on the number of domains that DPOD can monitor on a single gateway

• When there are no custom log targets defined on the Gateway, the Gateway supports Since the DataPower gateway currently supports up to 1,000 log targets, DPOD can monitor a maximum of 125 domains that DPOD can monitor.

• Before firmware 7.5.2.4, the Gateway supported 500 log targets. Because the default domain requires 3 log targets and each application domain requires 2 log targets, The Gateway without custom log targets supports a maximum of 248 domains. After firmware 7.5.2.4 this number were doubled.

• When you enable DPOD monitoring, one new log target is added to the default domain and 2 new log targets to each 333 domains if no other custom log targets are defined. See details and calculation below for more information.

• The total amount of log targets cannot exceed 1,000 and consists of:

  • One required default log target per domain (created when the domain is created with the name default-log), which cannot be removed.

  • Additional custom log targets, created by the customer for non-DPOD use.

  • Log targets created by DPOD - DPOD will create one log target for the default domain, and 2 log targets for each monitored application domain.

• Before you can enable DPOD monitoring:

  • View the list of defined domains, to ensure that no more than 125 domains are already defined.

  • Run the show log-targets command in Diagnostics mode to determine the number of log targets that are defined.

  Known workarounds: Unless the following calculation results in a positive integer, do not enable DPOD monitoring until you move domains to another Gateway:
  Max Log targets per device  - ((domains x 2) - 1) - number_log_targets

  • Count how many domains should be monitored by DPOD (it is possible to monitor a subset of domains) - DOMAINS_COUNT

  • Count how many log targets already exist in the DataPower gateway - EXISTING_LOG_TARGETS_COUNT
    You can view the existing log targets in the DataPower gateway WebGUI under default domain → Log Target Status → Show All Domains

  • Make sure the following calculation is true:
    EXISTING_LOG_TARGETS_COUNT + ((DOMAINS_COUNT x 2) -1) < 1,000

• Known workarounds: If the number of expected log targets exceeds the limit, do not enable DPOD monitoring. You may use the following methods to allow for DPOD monitoring:

  • Reduce the amount of monitored domains by setting up monitoring only for selected domains (see Configuring Monitored Gateways).

  • Delete unused domains or move domains to another gateway.

  • Delete unused custom log targets that were created for non-DPOD use.

B2B support is limited

• At present, the most important B2B features (e.g. transaction aggregation) are supported. Configuration sampling and specific filtering in dashboards are part of the current version.
