# VMware vCSA Services and Appliance Health for Checkmk 2.5 / vSphere 8   Monitor VMware vCenter Server Appliance and vSphere environments through REST and SOAP APIs.   Fully rewritten for Checkmk 2.5 and vSphere 8, based on ideas from [VCSA7 Health Status](https://exchange.checkmk.com/p/vcsa7-health-status).   ## Features   - vCSA services, health, storage, uptime, version and updates - NTP and time synchronization - Cluster, HA, DRS, DPM and admission-control status - ESXi connectivity and maintenance mode - Active vSphere alarms - CPU and memory metrics - Global resource aggregation - Collection-status monitoring - Checkmk Password Store support - Configurable WARN/CRIT thresholds   REST monitoring remains available when SOAP collection is unavailable.   Collection errors are reported through the `vCSA Collection status` service.   ## Requirements   - Checkmk 2.5.0 or newer - VMware vCenter Server Appliance / vSphere 8 - HTTPS access from Checkmk to vCenter - The standard Checkmk VMware vSphere monitoring requirements   For cluster and ESXi SOAP monitoring, install `pyVmomi` in the Checkmk site:   ```bash omd su SITE_NAME pip3 install pyvmomi ```   Replace `SITE_NAME` with the name of your Checkmk site.   Without `pyVmomi`, vCSA REST monitoring remains available, while cluster and ESXi SOAP checks are skipped.   ## Permissions   - **vSphere:** use the same account and permissions as Checkmk's built-in VMware vSphere monitoring - **vCSA:** add the account to `SystemConfiguration.ReadOnly`   ## Configuration   1. Install and enable the MKP. 2. Create the vCenter host in Checkmk. 3. Enable **Configured API integrations** for this host. 4. Go to **Setup > Agents > Other integrations**. 5. Add **VMware vCSA services and appliance health**. 6. Configure credentials, HTTPS port, timeout and TLS verification. 7. Restrict the rule to the vCenter host. 8. Activate changes and run service discovery.   Additional rules are available for appliance health, NTP, HA, DRS, DPM, maintenance mode, alarms and CPU/memory thresholds.   ## License   MIT License — Free Software
