HI,
Any idea why usage server is stopped with unexpected exception(is there any issue exits/logged already),do we need to add any additional packages/rpm/configurations other than installing the usage server monitor" Seen this issue on master build. [root@rhel631 ~]# service cloudstack-usage start Starting CloudStack Usage Monitor cloudstack-usage [ OK ] [root@rhel631 ~]# service cloudstack-usage status cloudstack-usage (pid 20999) is running...
