Automation support for the automatic restarting of the IFTASK process and the ability to generate core dumps through Ultra Automation Services was introduced. |
N5.8 |
Feature Description
In the 21.4 release, new functionality was added to the StarOS to enable the automatic restarting of the IFTASK process in the event of a failure. IFTASK process restart is enabled by default. Refer to the Release Change Reference, StarOS Release 21.4/Ultra Services Platform Release N5.7 for more information.
In this release, parameters related to this functionality are now available through the YANG models leveraged by the Ultra Automation Services (UAS) when deploying the Ultra Gateway Platform (UGP).
The upp param IFTASK_DISABLE_RESTART_OPT parameter is now available for use within the Service Function vdu-catalog configuration in either the AutoDeploy configuration file (for Ultra M deployments) or the AutoVNF configuration file (for stand-alone AutoVNF deployments).
AutoDeploy Configuration File Example:
vnfd vnfd_name vdu-catalog service_function_vdu_cat_name vdu-type session-function <---SNIP---> upp param IFTASK_DISABLE_RESTART_OPT value yes <---SNIP---> !
AutoVNF Configuration File Example:
autovnf:vdu-catalog service_function_vdu_cat_name vdu-type session-function <---SNIP---> upp param IFTASK_DISABLE_RESTART_OPT value yes <---SNIP---> !
This parameter is set to value yes (enabled) by default. To disable this functionality, remove the upp param IFTASK_DISABLE_RESTART_OPT parameter from the configuration file.
The StarOS optionally supports the generation of core dump files upon IFTASK process restart. You can enable this functionality through the iftask fullcore-enable in the Global Configuration Mode as part of your Day N configuration. Refer to the StarOS Command Line Interface Reference for more information.
