For a wide spread organization with a complex network infrastructure,
the Agent based scanning is most effective and provides easy deployment,
more security and low bandwidth.
The application provides an agent, which can be deployed in the network
workstations through various methods. [Refer Methods
of Agent Deployment]. Once the agent is deployed in the network workstations,
it scans all the workstations and provides easy access for remote assistance.
The following topics are discussed in this section:-
Choose to scan all
your Windows workstations in both, Agent and Agentless mode by selecting
the corresponding option from Agent Settings under the Admin tab. If you
have enabled Agentless mode, the Windows workstation and servers are scanned
using WMI. If you have enabled both the modes, the agent based scanning
is performed and if that fails, the agentless scanning is performed.
1. Windows is the only Supported
Platform for Agent.
2. The Ports used in Agent based Scanning are TCP 9000.
For a successful scan, the agent should communicate
with the ServiceDesk Plus server. The server details are configured under
Agent Configurations. By default, the server in which the application
is installed is populated as the server details.
You can modify these configurations to create your own Agent Configurations.
Name: The server name or IP address of the computer where ServiceDesk
Plus is installed. The agent residing in the client computers communicates
with the ServiceDesk Plus server using this Server Name/IP address.
Port: The port configured for the application.
The protocol used to communicate with the server.
Port: The port number of the agent.
at System Startup: On enabling this option, the agent scans the
workstation on every startup.
Click Create New Agent
button. Clicking on Cancel
takes you to the agent settings page.
You can also modify the
configurations to create your own Agent Configurations.
If the agent is installed
in all the Windows machines and if any of the below circumstances occurs,
the agent details can be updated using a script.
ServiceDesk Plus application is moved from
one server to another or if the AE port or protocol (http or https) has
If agent port needs to be changed in all the
machines or enable/disable scanning on system startup.
This script can be run as a logon script
in the Active Directory or manually in each machine to update the configurations
in the agent. While executing the script, the parameters should be in
the format "-servername <AE server name> -port <AE port>
-protocol <http or https >".

While performing a scan (Domain scan or Scheduling
a scan) through Agent or Agentless mode, some amount of data is obtained
in the ServiceDesk Plus Server. The data obtained in the AE Server through
an Agent scan is comparatively minimal to that of Agentless. The agent
transfers only the changes ("delta") that occur between two
subsequent scans to the server, and automatically strips out any unchanged
data, thus reducing the data transfer to 1 - 2kb instead of the usual
20 - 30kb.
Pros and Cons of Agent
based scan Pros:
Only one port is required
during scan, which can be configured under Admin -> Agent
settings -> Agent Configuration -> Agent Port.
Performs scan on system
boot up and pushes the data to AE application.
The data transfer in
agent scan is very minimal compared to agentless scan and even more less
when compared to delta scan (difference in data between two subsequent
scans is fetched).
Quick access to the remote
machine on performing Remote Control.
Easy to deploy agent
through active directory.
DCOM and RPC settings are eliminated.
Once the agent is installed
in all the machines, you can scan those machines from Linux server.
Agent based scan Cons:
Agent should be upgraded if the version is changed.
This can be performed from the Active Directory.
