Hi Spacewalk lovers Since we upgrade from 2.0 to 2.2, we encounter a capacity problem due to CPU usage overall. When users load a system page in the GUI, the tomcat process grow to 90% usage. Api and GUI become unavailable or very slow.
Our architecture is as following: 5 rhn proxies LVS Master/slave mode 1 front master: SERVICES="jabberd $TOMCAT httpd osa-dispatcher Monitoring MonitoringScout rhn-search cobblerd taskomatic" 1 front slave: SERVICES="jabberd $TOMCAT httpd osa-dispatcher Monitoring MonitoringScout " 1 cluster PGSQL Our masters have 2* Intel(R) Xeon(R) CPU E5-2609 / 92 RAM / raid 1 using CentOS 6.5. We have about 6000 systems registered, about 40 organizations and more than 600 channels (including cloned) My questions are: - Is it possible to scale spacewalk horizontally ? By changing lvs configuration to Active/Active ? By using HAProxy ? other ? - Is it possible to tune tomcat better than adding memory ? (we use actually -Xms8196m -Xmx16384m) - What is the maximum number of systems that we can register in 1 organisation ? (Actually our max seems to be 1700) - Is there a maximum number of systems that we can register in a Spacewalk cluster ?
