+
+============================
+Endpoint Monitoring overview
+============================
+
+
+EpMon is a standalone python based process targeting every OTC service. It
+finds service in the service catalogs and sends GET requests to the configured
+endpoints.
+
+Performing extensive tests like provisioning a server is giving a great
+coverage, but is usually not something what can be performed very often and
+leaves certain gaps on the timescale of monitoring. In order to cover this gap
+EpMon component is capable to send GET requests to the given URLs relying on the
+API discovery of the OpenStack cloud (perform GET request to /servers or the
+compute endpoint). Such requests are cheap and can be performed in the loop, i.e.
+every 5 seconds. Latency of those calls, as well as the return codes, are being
+captured and sent to the metrics storage.
+
+
+
+Currently EpMon configuration is located in system-config:
+https://github.com/opentelekomcloud-infra/system-config/blob/main/inventory/service/group_vars/apimon.yaml
+(this will change in future once CloudMon will take place)
+
+And defines the query HTTP targets for every single OTC service.
+
+EpMon dashboard provides general availability status of every service definition
+from service catalog:
+
+.. image:: training_images/epmon_status_dashboard.jpg
+
+Additionally it provides further details for the endpoints like response times,
+detected error codes or no responses at all.
+
+.. image:: training_images/epmon_dashboard_details.jpg
+
+EpMon findings are also reported to Alerta and notifications are sent to Zulip
+dedicated topic "apimon_endpoint_monitoring".

+
+In this case it seems that deployed ECS doesn't contain injected public SSH key
+which can point to issue with cloud init or metadata server.
+
+The playbooks can be run also manually on any OTC tenant and can be used
+for further investigation and analysis.

+What Are The Annotations?
+#########################
+
+Annotations provide a way to mark points on the graph with rich events. When you
+hover over an annotation you can get event description and event tags. The text
+field can include links to other systems with more detail.
+
+.. image:: faq_images/annotations.jpg
+
+
+In ApiMon Dashboards annotations are used to show the JIRA change issue types
+which change the transition from SCHEDULED to IN EXECUTION. This helps to
+identify if some JIRA change has negative impact on platform in real time. The
+annotations contain several fields which help to correlate the platform behavior
+with the respective change directly on the dashboard:
+
+ - JIRA Change issue ID
+ - Impacted Availability Zone
+ - Affected Environment
+ - Main component
+ - Summary

+.. _metrics_definition:
+
+=======
+Metrics
+=======
+
+The Ansible playbook scenarios generate metrics in two ways:
+
+- The Ansible playbook internally invokes method calls to **OpenStack SDK
+  libraries.** They in turn generate metrics about each API call they do. This
+  requires some special configuration in the clouds.yaml file (currently
+  exposing metrics into statsd and InfluxDB is supported). For details refer
+  to the `config
+  documentation <https://docs.openstack.org/openstacksdk/latest/user/guides/stats.html>`_
+  of the OpenStack SDK. The following metrics are captured:
+
+  - response HTTP code
+  - duration of API call
+  - name of API call
+  - method of API call
+  - service type
+
+- Ansible plugins may **expose additional metrics** (i.e. whether the overall
+  scenario succeed or not) with help of `callback
+  plugin <https://github.com/stackmon/apimon/tree/main/apimon/ansible/callback>`_.
+  Since sometimes it is not sufficient to know only the timings of each API
+  call, Ansible callbacks are utilized to report overall execution time and
+  result (whether the scenario succeeded and how long it took). The following
+  metrics are captured:
+
+  - test case
+  - playbook name
+  - environment
+  - action name
+  - result code
+  - result string
+  - service type
+  - state type
+  - total amount of (failed, passed, ignored, skipped tests)
+
+Custom metrics:
+
+In some situations more complex metric generation is required which consists of
+execution of multiple tasks in scenario. For such cases, the tags parameter is
+used. Once the specific tasks in playbook are tagged with some specific metric
+name the metrics are calculated as sum of all executed tasks with respective
+tag. It's useful in cases where the measured metric contains multiple steps to
+achieve the desired state of service or service resource. For example, boot up of
+virtual machine from deployment until successful login via SSH.
+
+.. code-block::
+
+    tags: ["metric=delete_server"]
+    tags: ["az={{ availability_zone }}", "service=compute", "metric=create_server{{ metric_suffix }}"]
+
+More details how to query metrics from databases are described on :ref:`Metric
+databases <metric_databases>` page.
