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:

|
|
|
|
Additionally it provides further details for the endpoints like response times,
|
|
detected error codes or no responses at all.

EpMon findings are also reported to Alerta and notifications are sent to Zulip
|
|
dedicated topic "apimon_endpoint_monitoring".
