Until now, this required correspondence with the IT Center via e-mail.<\/p>\n<p>Since this can involve a lot of back and forth, colleagues <a href=\"https:\/\/www.itc.rwth-aachen.de\/cms\/IT-Center\/IT-Center\/Team\/~epvp\/Mitarbeiter-CAMPUS-\/?allou=1&amp;gguid=0xD91E01F6C3D51E439F5365E0DA5FB893&amp;lidx=1\">Benedikt Paffen<\/a> and <a href=\"https:\/\/www.itc.rwth-aachen.de\/cms\/IT-Center\/IT-Center\/Team\/~epvp\/Mitarbeiter-CAMPUS-\/?allou=1&amp;gguid=0xAE999D14292AAC4B95A036B2260FBE82&amp;lidx=1\">Philipp Tomazin<\/a> from the <a href=\"https:\/\/www.itc.rwth-aachen.de\/cms\/IT-Center\/IT-Center\/Profil\/Organisation\/~esvd\/Abteilungen\/?lidx=1\">Division Networks<\/a> looked into the issue and came up with a more convenient solution.<\/p>\n<p>Based on the data center fabric (Cisco APIC, SDN), a web interface was programmed for self-service, which fetches the required data from the APIC via API requests. The result: The <a href=\"https:\/\/noc-portal.rz.rwth-aachen.de\/dc-admin\/en\/live\/tenants\">DC Admin<\/a>*.<\/p>\n<p>Currently the web interface is still in the beta test phase with a few customers. For all who are interested or would like to participate in the beta test phase, we show today which functions the DC Admin provides.<\/p>\n<p><!--more--><\/p>\n<h1>What the DC Admin supports<\/h1>\n<p>The DC Admin offers users the great advantage that all network information about the virtual machines (VMs) is bundled in one place. The configurations can be compiled independently.<\/p>\n<p>In addition, multiple VMs of the same type (same firewall settings) can be combined into one object. This makes it possible to perform desired configurations for any number of VMs at once instead of for each VM individually. This combination can also be dissolved again after the task has been completed.<\/p>\n<h1>Using the DC Admin<\/h1>\n<p>In the DC Admin, you can display different views: Live Tenants, EP Tracker, My VMs, and History.<\/p>\n<p>Each view has a specific focus, which we will introduce below. All applications of the DC Admin access the same database.<\/p>\n<h2>Live-Tenants<\/h2>\n<div id=\"attachment_10199\" style=\"width: 310px\" class=\"wp-caption alignright\"><a href=\"https:\/\/blog.rwth-aachen.de\/itc\/files\/2021\/10\/20211029-DC-admin-LiveTenants_EN.png\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-10199\" class=\"wp-image-10199 size-medium\" src=\"https:\/\/blog.rwth-aachen.de\/itc\/files\/2021\/10\/20211029-DC-admin-LiveTenants_EN-300x167.png\" alt=\"View in DC Admin: Live-Tenants\" width=\"300\" height=\"167\" srcset=\"https:\/\/blog.rwth-aachen.de\/itc\/files\/2021\/10\/20211029-DC-admin-LiveTenants_EN-300x167.png 300w, https:\/\/blog.rwth-aachen.de\/itc\/files\/2021\/10\/20211029-DC-admin-LiveTenants_EN-1024x568.png 1024w, https:\/\/blog.rwth-aachen.de\/itc\/files\/2021\/10\/20211029-DC-admin-LiveTenants_EN-768x426.png 768w, https:\/\/blog.rwth-aachen.de\/itc\/files\/2021\/10\/20211029-DC-admin-LiveTenants_EN.png 1371w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><p id=\"caption-attachment-10199\" class=\"wp-caption-text\">View in DC Admin: Live-Tenants <br \/>Source: Own illustration<\/p><\/div>\n<p>A tenant is a logical subdivision. In DC Admin, a tenant usually corresponds to an organizational unit depending on the institute code number (IKZ).<\/p>\n<p>Under Live-Tenants, all logical units to which the user is assigned are displayed. The content that is visible under Live-Tenants is determined by the networks to which the person in question is listed as a network contact.<\/p>\n<p>Clicking on a tenant loads a detailed view. All VMs belonging to the network are listed there. A button can be used to query further information about the tenant, such as apps, bridged domains (subnets) and firewall drops. This makes it possible to independently view what has been configured for the individual VMs.<\/p>\n<p>Users can enter the desired data themselves using the &#8220;request application profiles&#8221; button.<\/p>\n<p>The request is then sent directly via DC Admin to the relevant agents. This makes a manual request via the IT-ServiceDesk unnecessary.<\/p>\n<h2>EP-Tracker<\/h2>\n<div id=\"attachment_10200\" style=\"width: 310px\" class=\"wp-caption alignright\"><a href=\"https:\/\/blog.rwth-aachen.de\/itc\/files\/2021\/10\/20211029-DC-admin-EP-Tracker_EN.png\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-10200\" class=\"wp-image-10200 size-medium\" src=\"https:\/\/blog.rwth-aachen.de\/itc\/files\/2021\/10\/20211029-DC-admin-EP-Tracker_EN-300x167.png\" alt=\"View in DC Admin: EP-Tracker\" width=\"300\" height=\"167\" srcset=\"https:\/\/blog.rwth-aachen.de\/itc\/files\/2021\/10\/20211029-DC-admin-EP-Tracker_EN-300x167.png 300w, https:\/\/blog.rwth-aachen.de\/itc\/files\/2021\/10\/20211029-DC-admin-EP-Tracker_EN-1024x568.png 1024w, https:\/\/blog.rwth-aachen.de\/itc\/files\/2021\/10\/20211029-DC-admin-EP-Tracker_EN-768x426.png 768w, https:\/\/blog.rwth-aachen.de\/itc\/files\/2021\/10\/20211029-DC-admin-EP-Tracker_EN.png 1371w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><p id=\"caption-attachment-10200\" class=\"wp-caption-text\">View in DC Admin: EP-Tracker <br \/>Source: Own illustration<\/p><\/div>\n<p>Under EP-Tracker, short for EndPoint-Tracker, appears a search mask.
