CMDB
Overview
The CMDB tab manages tenant-level experience parameters related to the CMDB module — the default dashboard users see when entering CMDB, and the maximum number of nodes allowed in a CI topology graph. These settings affect the visual experience of all users in CMDB.
Configuration Items
Default Dashboard
| Property | Description |
|---|---|
| Business meaning | The dashboard displayed by default when users enter the CMDB dashboard module |
| When used | Lets users see the most valuable data overview as soon as they open the CMDB dashboard |
| Available values | All dashboards created in the current tenant |
| Default value | Infrastructure Overview dashboard |
First create the desired dashboard in Dashboard Management, then return to this settings page and select it from the drop-down list as the default.
Topology Node Limit
| Property | Description |
|---|---|
| Business meaning | The maximum number of nodes allowed to render in a CI topology graph |
| When used | Prevents oversized topologies from causing browser lag or crashes |
| Value range | 100 – 1000 |
| Default value | 500 |
When the number of nodes in a topology graph exceeds this limit, the system truncates the display and shows a node-count-exceeded notice. You can then reduce the node count by narrowing the query scope (fewer starting CIs, shorter relationship depth).
Raising the limit to 800 or 1000 lets you display larger topologies, but the browser must render more nodes and edges, which may cause lag on lower-powered devices. Set this according to the capability of the client devices in use.
