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.

4VMware vCenter VMWARE Read only user/passvmapp

Probes a Unix machine for VMWare Workstation information:

UNIX - Get VMWare Workstation

Probe to get information from vCenter about ESX hosts, resource pools, and virtual machines. Implementation details for this probe are located in a MID server script include called VMWarevCenterProbe.

VMWare - vCenter

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.:

VMWare - vCenter Clusters

Probe to get information about a vCenter's datacenters. The sensor will fire a probe for each type of vCenter object in each datacenter:
VMs, explored by the "VMWare - vCenter VMs" probe,
clusters, explored by the "VMWare - vCenter Clusters" probe,
datastores, explored by the "VMWare - vCenter Datastores" probe, and
networks, explored by the "VMWare - vCenter Networks" probe.

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:

VMWare - vCenter Datacenters

Probe Explores datastores, datastore hostmounts and datastore disks.This probe's implementation is located in a MID server script include named VMWarevCenterDatastoresProbe:

VMWare - vCenter Datastores

Explore virtual networks.

This probe's implementation is located in a MID server script include named VMWarevCenterNetworksProbe.:

VMWare - vCenter Networks

Probe Explores NICs installed in virtual machines.This probe's implementation is located in a MID server script include named VMWarevCenterVMNICsProbe:

VMWare - vCenter VM NICs

Probe Explores VMs.This probe's implementation is located in a MID server script include named VMWarevCenterVMsProbe:
