When you connect to a single host using the vSphere Client, you can monitor the host health status, and view events, system logs, and performance charts. View Charts You can connect directly to ESX/ESXi hosts and view information about resource usage in line chart form. Working with Advanced and Custom ChartsUse advanced charts, or create your own custom charts, to see more performance data. Advanced charts can be useful when you are aware of a problem but need more statistical data to pinpoint the source of the trouble. Monitoring Host Health StatusYou can use the vSphere Web Client to monitor the state of host hardware components, such as CPU processors, memory, fans, and other components. Monitoring Events, Alarms, and Automated Actions vSphere includes a user-configurable events and alarms subsystem. This subsystem tracks events happening throughout vSphere and stores the data in log files and the vCenter Server database. This subsystem also enables you to specify the conditions under which alarms are triggered. Alarms can change state from mild warnings to more serious alerts as system conditions change, and can trigger automated alarm actions. This functionality is useful when you want to be informed, or take immediate action, when certain events or conditions occur for a specific inventory object, or group of objects. Viewing Solutions You can deploy, monitor, and interact with solutions that are installed in a vCenter Server instance with the vCenter Solutions Manager. The Solutions Manager displays information about the health of a solution. Configure SNMP Settings for vCenter ServerTo use SNMP with vCenter Server, you must configure SNMP settings. System Log FilesIn addition to lists of events and alarms, vSphere components generate assorted logs.
