Certain probes, controlled by MID Servers, perform Orchestration tasks on remote
computers, such as restarting a server or creating virtual machines from templates.
How Orchestration probes work
When a Workflow executes an Orchestration activity, that activity launches a probe, which
writes an output record to the ECC Queue. The MID Server selected for the
activity checks the ECC Queue for assignments, and then executes the appropriate probe to do
the work on the target machine. The information about the activity (machine restarted, files
copied, etc.) that is returned from the target machine by the probe is written to the ECC
Queue as an input record. This information is then sent from the ECC Queue
to a sensor that is built into the Workflow activity. The Workflow is updated, and the next
activity is executed.
주:
The probe parameters are set by the activities that
launch the probe.

Probe List
The base system includes the following Orchestration probes (Orchestration > Definition > Probes).

Probe Name
ECC Queue Topic
ECC Queue Name
Description
Command
Command
A probe that runs a local command on the MID server.
DNS Name Resolver
DNSNameResolver
A probe that resolves a fully qualified domain name (FQDN) into an IP
address. The probe executes MID Server queries in parallel. It utilizes DNS lookup
by the MID Server host OS to make use of the OS maintained DNS cache. It also
leverages the hosts file on the OS.
SCPCommand
SCPCommand
A probe that copies files securely from one machine to another. The copy
function is performed using the MID Server as a tunnel.
Shazzam
Shazzam
A probe that identifies active devices.
SNMPProbe
SNMP
SNMP Query
This is a generic SNMP probe.
SOAPProbe
SOAPProbe
A probe that sends a SOAP request to target machine.
SSHCommand
SSHCommand
A probe that executes shell scripts from a command line after logging in to a
target machine via SSH.
SSHCommandLong
SSHCommandLong
A probe that executes long running shell scripts from a command line after
logging in to a target machine via SSH.
VMWare
VMWareProbe
A generic VMware probe that executes the MID Server script include in the
ECC queue name that is set by a VMware Orchestration activity.
This probe can run any MID Server script include.
Windows -
PowerShell
PowerShell
Windows -
PowerShell
A probe that runs a Windows PowerShell script on
the MID Server. The PowerShell script is provided as the value of a parameter with
name ending in .ps1. Two variables are available to the
script:
$computer: The computer pointed to as the
source for this probe
$cred: A PowerShell credential, using a user name and
password from the Credentials table, that logs into
$computer successfully.
