To install the EventLog Analyzer agent using the product console,
In the Settings tab, navigate to Admin Settings → Manage Agents.
Click + Install Agent and then the + icon corresponding to Device(s).
Select the devices on which you want to install the agent.
Enter the login name and password to access the device(s). This account should have admin privileges to install the agent successfully. Or you can also choose the Use Default Credentials option.

Use the Verify Credential link to validate the credentials entered.
Finally, click Install Agent to initiate agent installation.
Using GPOs:
Before beginning to install the EventLog Analyzer agent using GPOs, place the following files in a network-shared folder of the server:
Create a new GPO as follows (based on the Windows Server version):
Open Group Policy Management.
In the left pane, right-click the Group Policy Objects container and select New.
Give the GPO a suitable name and click OK.
Step 2: Configuring script settings
Right-click the newly created GPO and click Edit.
For Windows Server 2003, in the right pane of the GPO editor, double click Computer Configuration and navigate to Windows Settings → Scripts (Startup/Shutdown) → Startup.
For Windows Server 2008 and later, navigate to Computer Configuration → Policies → Windows Settings → Scripts (Startup/Shutdown) → Startup.
Right-click Startup and in the dialog box that appears, click Add.
In the Add Script dialog box, click Browse and select InstallEventLogAgent.vbs from the shared location.
In the Script Parameters field, enter the following parameters:
Copy to Clipboard
/MSIPATH:"< share path of msi file>" /SERVERNAME:" <ELA server name>" /SERVERIPADDRESS:" <IP address of server>" /SERVERPORT: "<port occupied by server>" /SERVERPROTOCOL:" <protocol (http/https)>"
Note: Ensure that the Agent MSI files in the shared folder are the latest version. You can find the latest version in the following path: <Installation directory>:\EventLog Analyzer\lib\native.
In the left pane of the Group Policy Management Editor, navigate to Computer Configuration → Administrator Templates → System.
Under System, select Scripts.
In the right pane of the GPO Editor, double-click Run logon scripts synchronously and enable it.
Click Apply and then OK.
Similarly, enable Maximum wait time for Group Policy scripts.
Then, navigate to Logon under System.
In the right pane, double-click Always wait for the network at startup and logon and enable it.
Click Apply and then OK.
Then, navigate to Group Policy under System.
In the right pane, double-click Group Policy slow link detection and enable it.
Click Apply and then OK.
Step 4: Applying the GPO
Tip: For installing the agent on multiple computers at one go, create an AD group and add all the computers on which the agent needs to be installed to the group. Then, apply the GPO to that group.
On the left pane of the Group Policy Management Editor, right-click the GPO you are working on and select Properties.
Navigate to the Security tab and unselect the Apply Group Policy permissions for Authenticated Users.
Click Add and in the dialog box that appears, click Object Types.
If you want to apply the GPO to computers directly, ensure Computers is selected and then click OK. For applying it to a group, ensure Groups is selected and then click OK.
Enter the name of the desired computer(s) and/or group(s) and click Check Names.
Select the desired computer(s) and/or group(s) and click OK to return to the properties dialog box.
In the Security tab, apply the following permissions to the selected group(s) and/or computer(s):
(i) Read > Allow
(ii) Apply Group Policy > Allow
Click Apply and then OK.
Right-click on the Domain and click on "Link an Existing GPO..." option
Now select the GPO you are working on and Click OK.
Restart the computers to complete applying the GPO and wait for the reset password / unlock account link to appear on the Windows logon screen.
Note: After installing the EventLog Analyzer agent using GPO, make sure to disable or delete the GPO, or the scripts will continue to run at every startup.
Using Microsoft System Center Configuration Manager (SCCM) or some similar software deployment tool:
Place Eventlogagent.msi in a network-shared folder.
In the device(s) on which the agent needs to be installed, execute the following command:
<eventlog_server> = Name of the server on which EventLog Analyzer is installed
<eventlog_server_port> = Web server port used by EventLog Analyzer (By default Eventlog Analyzer uses web server port 8400 for HTTP)
For example: localhost:8400/event/downloadMsi.nms?platform=windows
EventLogAgent.msi will be downloaded automatically. Double-click EventLogAgent.msi to start installation.
After clicking Next in the welcome screen and the Confirm Installation dialog box, the following dialog box will be displayed. Enter the details and click OK.
Installation will be completed.
For Linux devices,
The agent has to be configured in Manage File Integrity Monitoring page of EventLog Analyzer. Refer Configuring File Integrity Monitoring to configure the agent in Linux devices. If installation fails due to permission denial, you can manually install it by executing the following command.
Installation Command:
HTTP Command:
Copy to Clipboard
eval "wget http://<eventlog_server>:<eventlog_server_port>/downloadMsi.nms?platform=agentInstaller -O AgentInstaller && sh AgentInstaller http://<eventlog_server>:<eventlog_server_port> lesssecure"
eval "wget http://ubuntu:8400/downloadMsi.nms?platform=agentInstaller -O AgentInstaller && sh AgentInstaller http://ubuntu:8400 lesssecure"
For Sudo User:
Make sure to include the prefix "sudo -s" before running the installation command.
Note: For non-sudo user, ensure that you are logged in as the auditing user. This is important because the agent will automatically consider the current user as the auditing user. If you are not logged in as the auditing user, please refer to the troubleshooting tips for setting privileges for agent folder.
