Limitation on the number of domains that DPOD can monitor on a single IDG
When you define no custom log targets on the IDG, the IDG supports a maximum of 125 domains that DPOD can monitor when the IDG defines no custom log targets.
By default, the IDG supports 500 log targets. Because the defaultdomain requires 3 log targets and each application domain requires 2 log targets, The IDG without custom log targets supports a maximum of 248 domains.
When you enable DPOD monitoring, 1 log target is added to the default domain and 2 log targets to each application domain.
Before you can enable DPOD monitoring:
- View the list of defined domain, 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 IDG.
500 - ((domains x 2) - 1) - number_log_targets
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.
Known workarounds:
Callable rule invocation appears as a separate transaction
At present, monitored devices do not report the front end response payload size nor do they report on the backend request and response.
Known workarounds:
None. Resolution of this issue is part of the product Roadmap.
Error is not displayed in "Extended transactions"
The extended transaction is the only feature of DPOD that involves instrumentation of an XSLT transformation to the Web Service Proxy policy (request / response and error rules).
The instrumentation is integrated by the system only when initiated by the system administrator and not by default.
The behaviour when an error is raised by the service (WS-Proxy) depends on the applicable scenario:
No error rule in the service where the error is raised. Previous services are configured with "Process HTTP errors = on"
As there is no error rule, an extended transaction log record will not be generated for the error, and it will not be displayed on the "Extended Transactions" screen.
The extended transaction display will resemble the following (note: one record is missing)
No error rule in the service where the error is raised. Previous services do have error rule configured
As there is no error rule, an extended transaction log record will not be generated for the error, and it will not be displayed on the "Extended Transactions" screen.
However, as previous services do have an error rule, the "Extended Transactions" display will resemble the following:
The Extended Transaction facility does not support APIC / APIM.
You must NOT run it in API-C / API-M DomainsNote: In some cases, the Extended Transaction is not deployed on MPG services. This is due to the diversity of configuration in these services.
Customers are encouraged to open a PMR and provide the service configuration - so these cases can be addressed and resolved.
No support for DHCP
DPOD does not support DHCP network configuration. Please refer to Change Appliance Network Address
Known workarounds:
None.
Operating System supported locale
The only supported operating system locale definition for DPOD is en_US.UTF-8 as described in the installation prerequisites
Known workarounds:
None.
