VMware "In-Guest" DataSources - Version 1.0 - LogicMonitor Custom Development Summary: The following provides information and deployment instructions for the application of hypervisor-level monitoring data - as presented within a Windows virtual machine in LogicMonitor. There are three "InGuest" VMware DataSources - they are: VMware_vSphere_VMperformance_InGuest (locator code: CHLF7C ) VMware_vSphere_VMsnapshots_InGuest (locator code: 9YF42D ) VMware_vSphere_VMstatus_InGuest (locator code: ZMEJ6P ) How it Works: These datasources were cloned from the official LogicMonitor VMware DataSources with ‘_InGuest’ appended to the end of the standard name. They have been altered in the following fashion to apply them 'within' the virtual machine device: A critical feature built into the DataSources is the ability to ‘override’ a vCenter location with ‘esx.url.’ ○ This allows us to apply the DataSource to a VM and point it to vCenter for data. The AppliesTo language is updated to apply the DataSources to Windows Virtual Machines: ○ system.model =~ "Vmware Virtual Platform" && esx.url && esx.user && esx.pass The host property variable is switched from system.hostname to system.sysname: ○ def host = hostProps.get("system.sysname") The Active Discovery of virtual machines is limited to the device hostname to which it is applied: ○ ManagedEntity[] vms = new InventoryNavigator(rootFolder).searchManagedEntity("VirtualMachine","${host}"); Implementation: Three properties are required to be applied to the virtual machine device(s) in LogicMonitor: esx.user esx.pass esx.url in format: https://<vcenteripaddress>/sdk Once the device properties are present, the AppliesTo language will kick in and the DataSources will apply. Suggestion: create a dynamic group of Windows virtual machines, and set the ‘ESX’ properties at that group level. Notes: These DataSources are custom development and officially unsupported by LogicMonitor. Restrict the application of property esx.url to ONLY the virtual machines needed. This property will apply to ESXi hosts if allowed, which impacts vCenter collection and performance. Deploy this in stages - we will be increasing the load on vCenter due to the additional API queries. We do not currently identify Linux VM’s out of the box, for now this is Windows-only. Automated detection of VM to vCenter relationship is difficult at the device level, hence the need for esx.url. vCenter is the preferred integration point for esx.url, but an ESXi host should also work (until the VM moves.)
