Azure Sentinel Onboarding Log Sources

After you onboard Microsoft Sentinel into your workspace, use data connectors to start ingesting your data into Microsoft Sentinel. Microsoft Sentinel comes with many out of the box connectors for Microsoft services, which integrate in real time. For example, the Microsoft Defender XDR connector is a service-to-service connector that integrates data from Office 365, Microsoft Entra ID, Microsoft Defender for Identity, and Microsoft Defender for Cloud Apps.

Built-in connectors enable connection to the broader security ecosystem for non-Microsoft products. For example, use Syslog, Common Event Format (CEF), or REST APIs to connect your data sources with Microsoft Sentinel.

Microsoft Sentinel solutions provide packaged security content, including data connectors, workbooks, analytics rules, playbooks, and more. When you deploy a solution with a data connector, you get the data connector together with related content in the same deployment.

Configure Linux Syslog Forwarder

Change Ubuntu Ip from DHCP to Static

For ip address: ip a 
For Gateway: ip r
For DNS: In Ubuntu 18.04 and 20.04 you can use systemd-resolve --status. In newer versions use resolvectl status.
or using nmcli command, you might need to install it first.
nmcli conn modify "System eth0" ipv4.ignore-auto-dns yes nmcli conn modify "System eth0" ipv4.dns "192.168.24.7 8.8.8.8" systemctl restart NetworkManager

Add a super user in:

adduser test1
usermod -aG sudo test1
su - test1
sudo -i
sudo ls -la /root/

Meraki and Citrix vCenter

Since both are not using Azure Monitor Agent (AMA or MMA) to collect logs, and using Operation Management Suite (OMS) for it, I am putting both configuration steps in this section:
1 Install OMS agent

Download and install it in Linux Syslog Forwarder
