Node exporter exposes information of each VDU to Prometheus, and to monitor \nvms and physical nodes, the exporter is essential.\n\n2) What about cAdviser, Openstack-exporter\n-\u003e cAdvisor is not meant to monitor physical nodes or vms. It is in Kubernetes\npod. Simply it is a monitoring agent in the Kubernetes pod to expose its \nmetrics. cAdvisor gives container related information. And it runs without \ninstallation. So we don\u0027t need to make any VNFD for cAdvisor. But we\u0027ll provide\nsome manual to give users how to monitor with cAdvisor.\nAnd for Openstack-exporter, it also does not give you any information of VDUs, \nor instances. This exporter monitors holistic OpenStack status. The exporter \nis installed in openstack host, so we don\u0027t need VNFD to install it.\nYou can find some metrics on the readme file. \n(ref1. openstack-exporter :\n https://github.com/att-comdev/prometheus-openstack-exporter)","commit_id":"6f058c78cb31c92e6bb106abab1537aa8c0289f7"},{"author":{"_account_id":18955,"name":"dharmendra","email":"dharmendra.kushwaha@gmail.com","username":"dharmendra"},"change_message_id":"85ce8f786b6c0f3a3e325b5570dea0d506ad418a","unresolved":false,"context_lines":[{"line_number":132,"context_line":" | | +-------|----------------+   +------------------|-----+ | |"},{"line_number":133,"context_line":" | | |       |   VDU          |   |          VDU     |     | | |"},{"line_number":134,"context_line":" | | | +-----+--------------+ |   | +----------------+---+ | | |"},{"line_number":135,"context_line":" | | | |      Exporters     | |   | |     Exporters      | | | |"},{"line_number":136,"context_line":" | | | +-----^--------------+ |   | +----------------^---+ | | |"},{"line_number":137,"context_line":" | | |       |                |   |                  |     | | |"},{"line_number":138,"context_line":" | | | +-----v--------------+ |   | +----------------v---+ | | |"}],"source_content_type":"text/x-rst","patch_set":23,"id":"9fb8cfa7_960b76d4","line":135,"range":{"start_line":135,"start_character":14,"end_line":135,"end_character":23},"in_reply_to":"bfb3d3c7_9b0c1fed","updated":"2019-06-11 07:59:40.000000000","message":"Thanks for explanation.
