MidServer Services Architecture
The Management, Instrumentation, and Discovery (MID) Server is a Java application that runs as a Windows service or UNIX daemon on a server in your local network.
The MID Server facilitates communication and the movement of data between a ServiceNow instance and external applications, data sources, and services.
| The MID Server enables communication between a Servicenow Instance and the customer network |
| It is a Java Application that runs as a Windows Service or a Unix Dameon |
| It requires only an outbound connection on Port 443 |

MIdServer Services Requirements
The Management, Instrumentation, and Discovery (MID) Server is a Java application that runs as a Windows service or UNIX daemon on a server in your local network. The MID Server facilitates communication and the movement of data between a ServiceNow instance and external applications, data sources, and services.
Windows server: To discover Windows-based servers, run Service Mapping patterns, or execute Orchestration commands on Windows devices, the MID Server must be installed on a Windows server. The MID Server supports all Windows Server 2008, 2012, and 2016 editions, virtual machines, and 64-bit systems. Note: .NET Framework version 3.5, 4.0, 4.5, 4.6, or 4.7 is required for Service Mapping support and for Windows pattern-based discovery. |

Implementation details for this probe are located in a MID server script include called VMWarevCenterProbe. Probe Explores clusters and resource pools. Relate each cluster to its resource pools, ESX hosts and its containing folder or datacenter. The sensor will trigger the "ESX Hosts" probe to explore ESX hosts.This probe's implementation is located in a MID server script include named VMWarevCenterClustersProbe.: Probe to get information about a vCenter's datacenters. The sensor will fire a probe for each type of vCenter object in each datacenter: This probe's implementation is located in a MID server script include named VMWarevCenterDatacentersProbe. As of the Istanbul release this probe replaces the "VMWare - vCenter" probe for Discovery: Probe Explores datastores, datastore hostmounts and datastore disks.This probe's implementation is located in a MID server script include named VMWarevCenterDatastoresProbe: Explore virtual networks. This probe's implementation is located in a MID server script include named VMWarevCenterNetworksProbe.: Probe Explores NICs installed in virtual machines.This probe's implementation is located in a MID server script include named VMWarevCenterVMNICsProbe: Probe Explores VMs.This probe's implementation is located in a MID server script include named VMWarevCenterVMsProbe: | |||
