+
+// This module can be included from assemblies using the following include statement:
+// include::<path>/con_manifest-features.adoc[leveloffset=+1]
+
+// The file name and the ID are based on the module title. For example:
+// * file name: con_my-concept-module-a.adoc
+// * ID: [id='con_my-concept-module-a_{context}']
+// * Title: = My concept module A
+//
+// The ID is used as an anchor for linking to the module. Avoid changing
+// it after the module has been published to ensure existing links are not
+// broken.
+//
+// The `context` attribute enables module reuse. Every module's ID includes
+// {context}, which ensures that the module has a unique ID even if it is
+// reused multiple times in a guide.
+//
+// In the title, include nouns that are used in the body text. This helps
+// readers and search engines find information quickly.
+// Do not start the title with a verb. See also _Wording of headings_
+// in _The IBM Style Guide_.

+= Monitoring the resource usage of {OpenStack} services
+
+Monitor the resource usage of the {OpenStack} services, such as the APIs and other infrastructure processes, to identify bottlenecks in the overcloud by showing services running out of compute power. Enable the `collectd-libpod-stats` plug-in to gather CPU and memory usage metrics for every container running in the overcloud.
+
+.Prerequisites
+
+* You have created the `stf-connectors.yaml` file. For more information, see xref:configuring-red-hat-openstack-platform-overcloud-for-stf_completing-the-stf-configuration[].
+* You are using the most current version of {OpenStack}: {OpenStackVersion}.
+
+.Procedure
+
+. Open the `stf-connectors.yaml` file.
+
+. Add the following configuration to `parameter_defaults`:
++
+----
+  CollectdEnableLibpodstats: true
+----
+
+. Continue with the overcloud deployment procedure.
