The docs for the 3.6 metrics installation (https://access.redhat.com/documentation/en-us/openshift_container_platform/3.6/html/installation_and_configuration/install-config-cluster-metrics#deploying-hawkular-openshift-agent) need to be updated. The way to install metrics in HOSA has changed in 3.6 and its now handled in the ansible configuration file. The docs for master already contain this change, it just needs to be backported to the 3.6 branch.
I believe this change was made to the 3.6+ docs on sept. 29 through: https://github.com/openshift/openshift-docs/pull/5419 The `openshift_metrics_install_hawkular_agent` variable is at the bottom of table 2 in: https://docs.openshift.com/container-platform/3.6/install_config/cluster_metrics.html#metrics-ansible-variables Please verify that this meets your needs.
from https://bugzilla.redhat.com/show_bug.cgi?id=1510084#c1 its not in the 3.6 docs, but its already been committed in master. This issue is to get the changes in the 3.6 docs.
@matt -- Please check this link, that is for 3.6 https://access.redhat.com/documentation/en-us/openshift_container_platform/3.6/html/installation_and_configuration/install-config-cluster-metrics#deploying-hawkular-openshift-agent openshift_metrics_install_hawkular_agent Set to true to install the Hawkular OpenShift Agent (HOSA). Set to false to remove the HOSA from an installation. HOSA can be used to collect custom metrics from your pods. This component is currently in Technology Preview and is not installed by default.

This component is currently in Technology Preview > and is not installed by default. The link you pointed to, the whole 32.7 section is completely wrong and needs to be removed. That is not how we install or deploy HOSA anymore. Table 32.2 does describe how to install it using ansible, but we still need to remove the 32.7 section.
The "Deploying the Hawkular OpenShift Agent" section is present in 3.6, not 3.7+. So, changing the BZ version to 3.6.0 https://docs.openshift.com/container-platform/3.6/install_config/cluster_metrics.html#deploying-hawkular-openshift-agent"
Matt -- Sorry I took so long to deal with this. I removed the "Deploying the Hawkular OpenShift Agent" section from the 3.6 docs. The section was removed from 3.7+ in a separate PR that was not rolled back to 3.6. See: https://github.com/openshift/openshift-docs/pull/8281 Michael
