7.7. Loading Capacity Data from a File

Procedure 7.1. To Load Capacity Data from a File:

1. Run the following command to gather capacity data on a broker host, which then records the output to a file. Replace yaml with json, if needed:

   # oo-stats -f yaml > /tmp/stats.yamloo-stats -f yaml > /tmp/stats.yamloo-stats -f yaml > /tmp/stats.yamloo-stats -f yaml > /tmp/stats.yaml

2. Copy /tmp/stats.yaml to the host running the Administration Console, if needed.
3. Set /tmp/stats.yaml in the STATS_FROM_FILE parameter in the /etc/openshift/plugins.d/openshift-origin-admin-console.conf file.
4. SELinux limits what the broker application can read (for example, it cannot ordinarily read /tmp entries). To ensure that the broker can read the data file, adjust its context as follows:

   # chcon system_u:object_r:httpd_sys_content_t:s0 /tmp/stats.yamlchcon system_u:object_r:httpd_sys_content_t:s0 /tmp/stats.yaml

5. Restart the broker:

   # service openshift-broker restart
