Adding a VMware ESXi host to the SysAid Asset List and CI (CMDB) can indeed be challenging since installing a traditional agent on ESXi is not feasible. However, you can use SNMP to monitor and manage your VMware ESXi hosts within SysAid. Here are the steps to add your VMware ESXi host to the Asset List and CI using SNMP:

1. **Enable SNMP on VMware ESXi:**
- Log into your ESXi host using the vSphere client.
- Navigate to the 'Configuration' tab, and under 'Software', select 'Security Profile'.
- In the 'Services' section, click on 'Properties'.
- Find 'SNMP Service' and click on 'Options'.
- Configure the SNMP service by setting the community strings and enabling the SNMP service.

2. **Configure SNMP in SysAid:**
- Log into your SysAid Administrator account.
- Go to 'Settings' > 'Network Discovery'.
- Set up your SNMP credentials and ensure they match the community strings configured on your ESXi host.
- Add the IP range or specific IP of your ESXi host to the list of devices to be scanned.

3. **Run the SNMP Scan:**
- Initiate a network discovery scan in SysAid to detect your ESXi host.
- Once the scan is complete, your ESXi host should appear in the Asset List.

4. **Add to CI (CMDB):**
- Once your ESXi host appears in the Asset List, you can manually add it to the CI list if it does not automatically populate.
- Go to the CMDB module in SysAid and create a new CI entry for your ESXi host, linking it to the corresponding asset if necessary.

By following these steps, you should be able to successfully monitor and manage your VMware ESXi host within SysAid using SNMP without the need for an agent. If you encounter any issues during this process, consider reaching out to SysAid Support for further assistance.
