Managing vCenter Inventories in up.time
After a VMware vCenter server has been added as an Element to up.time, you can manually manage all of its inventory. By default, all of a VMware vCenter’s components—ESX hosts and clusters, and their child VMs—are monitored by up.time. As a central monitoring configuration point, the VMware vCenter Element gives you the ability to determine which VMs are monitored in up.time and as a consequence, which VMware vSphere metrics are kept in the DataStore.
You can select VMs or an ESX host to be "ignored" by up.time. When VMs are ignored, their topological relationship to other VMware vCenter components is retained, but their metrics are no longer recorded to the DataStore, and they no longer count toward your license.
As the topology of your virtual infrastructure changes, you can change the contents of the ignore list. Historical data for VM Elements are retained in the DataStore, regardless if they are currently being monitored or ignored, allowing administrators to continue to perform diagnosis on a continuously changing virtual environment.

If graphs or reports are generated that include time or date ranges where no data were collected for a VM Element, those ranges in the charts will show no data. |
Although there are no resource-related reasons why you would not want up.time to monitor all ESX servers in your virtual infrastructure, other factors may dictate your monitoring policies:
- since the VMs on your ESX servers count toward your up.time license, you may have resource monitoring restrictions that require prioritization
- you are not interested in keeping performance metrics for some parts of your virtual infrastructure (e.g., some VMs are being used for testing, and are not considered mission-critical)
- similarly, as ignored VMs do not appear in live monitoring pages in up.time such as Global Scan or the Resource Scan dashboards, you may want to exclude non-essential VMs to avoid cluttering the views
On the VMware vCenter Element’s Info page, you can view its complete inventory, broken down by logical groupings created in the vSphere Client (e.g., by datacenter). It is here you can add or remove ESX hosts or VMs (as individual machines, or in groups at the datacenter or cluster level) from the ignore list.
For license management, ignoring or monitoring a parent object will correspondingly free up or use license spots for all of its child objects, provided there is space. For example, if the VMware vCenter Element has been configured to Collect Virtual Machine data, adding an ESX host will automatically include its VMs, each of which will count toward your license. Consider the following outcomes:
- if there is enough license space for the ESX host and all of its VMs, they will be monitored
- if there is no more license space, the ESX host and all of its VMs will be added (with its hierarchy intact) to the list of ignored Elements
- if there is license space for some of the Elements, the ESX host will be added and monitored, and each child VM will be added to the monitored list until license space has run out; the remaining VMs are added to the list of ignored Elements
Once VMware vCenter objects have been added, you can manage license usage by moving Elements from monitored inventories to lists of ignored Elements, or vice versa.

If you configured the VMware vCenter server to not collect and report on VM data, and only work with ESX hosts and clusters, inventory management will obviously is done only be done at that inventory level. |
Viewing vCenter Inventory Summaries
To see an overview of your VMware vCenter Element’s inventory, do the following:
- In the My Infrastructure panel, click the gear icon beside the VMware vCenter server, then in the pop-menu, select View.
- On the VMware vCenter Element profile page, ensure the Info tab is selected.
- Click Inventory Summary.
On this page, you will see your VMware vCenter server’s total available resource counts, further broken down by datacenter.
Removing Elements from Monitored Inventories
To stop VMware vCenter server Elements from being monitored by up.time, do the following:
- In the My Infrastructure panel, click the gear icon beside the VMware vCenter server, then in the pop-menu, select View.
- On the VMware vCenter Element profile page, ensure the Info tab is selected.
- Click Inventory Detail.
- In the vCenter Inventory Detail page, select the checkboxes that correspond to the ESX hosts or clusters, or (if applicable) individual VMs that you want to stop monitoring.
- Click Add Selected Elements to Ignore.
The inventory page will refresh, with your selections appearing in the Ignored Elements section.
Re-adding Ignored Elements to Monitored Inventories
To resume monitoring VMware vCenter server Elements in up.time, do the following:
- In the My Infrastructure panel, click the gear icon beside the VMware vCenter server, then in the pop-menu, select View.
- On the VMware vCenter Element profile page, ensure the Info tab is selected.
- Click Inventory Detail.
On the vCenter Inventory Detail page, from the Ignored Elements list, select the checkboxes that correspond to the ESX hosts or clusters, or (if applicable) individual VMs that you want to start monitoring.
Info To streamline the process, you can only select or remove VMs or datacenters as they were added. For example, if you added an entire datacenter to the ignore list, you cannot select individual VMs.
Click Remove Selected Elements from Ignore List.
The inventory page will refresh, with your selections appearing in the active monitoring section.
