ManageEngine OpManager Plus Network Monitoring Bootcamp

Explore how snmp collects data from managed devices via an snmp agent, with read-only and read-write access, translated by mip for the network management station.

Compare SNMP versions 1, 2, and 3, focusing on security models and features like get bulk and 64-bit counters. Understand interoperability challenges and workarounds, including proxies and dual-version management.

Explore SNMP get and SNMP set, noting read-only versus read-write access. Understand plain text community strings, the risk, and the need to lock down management stations; compare traps with polling.

Identify how object identifiers (OIDs) from ITU-T and ISO IEC name any object with an unambiguous, persistent name, define an SNMP data structure through MIBs, and support private enterprise hierarchies.

Apply an understanding of SNMP polling over UDP, contrasting its lightweight, connectionless transport with TCP's overhead, and explain secure SNMP using TLS/DTLS on ports 161, 10161, 162, and 10162.

Build a practical network monitoring lab with Active Directory, Mikrotik, ESXi 6.7, iSCSI, and a monitoring server to practice with tools like SolarWinds or PRTG in a home lab.

Install esxi hypervisor in a monitoring lab using vmware workstation, download vSphere hypervisor 6.7 update 3, create a virtual machine, and configure net zero bridging with a static ipv4 address.

Install a virtual machine inside the esxi hypervisor, upload the Windows Server 2019 ISO to the datastore, configure virtual machine settings, and power on to complete the installation.

Install a vCenter server appliance with the VCSA ISO, configure DNS in Active Directory, and deploy a lab with a data center and iSCSI host.

Install Windows Server in a virtual machine, install Active Directory and DNS, promote to a domain controller for a new forest named lab.local.

Install Cisco IOSv Router in a lab using VMware Workstation, import the VMDK/OVF, assign IP 192.168.10.4, and save the configuration to startup while enabling SSH/Telnet via a serial port.

Add a FortiGate firewall by importing its VM OVA into VMware Workstation and upgrading compatibility. Configure a static ip, enable http, https, and ping, then access it in a browser.

Learn to create and deploy a Windows or Linux template in VMware Workstation by preparing the OS, running Sysprep, snapshotting, enabling template mode, and cloning for rapid deployments.

Clone a virtual machine template to install the monitoring server, allocate two vcpus and six gigabytes of ram, add two disks with thick provisioning, then sysprep for production deployment.

Install ManageEngine App Manager Plus on a Windows Server in a VM, join the domain, configure ports and database options, and access the App Manager UI for network monitoring.

Enable ssh on esxi and configure the SNMP community lab from the monitoring server, then restart the SNMP service and verify SNMP is enabled on the esxi host.

Enable snmp on the vCenter server, then add it to the app manager monitoring server by configuring the community, target, and credentials, and discover the vCenter and its virtual machines.

Enable SNMP on the Windows server, configure the trap destination and community string, adjust firewall rules, add the device to OpManager Plus, and rediscover to monitor performance.

Enable SNMP on Mikrotik and connect it to app manager monitoring server using Winbox; configure communities and IP SNMP, then add the device to inventory and review interfaces and performance.

Enable snmp on FortiGate firewall and connect it to the monitoring server by configuring snmp agent, community string, and interface monitoring to visualize performance graphs.

Identify the correct ethernet interface on devices for real-time monitoring and traffic analysis. View interface details, utilization graphs, and essential fields like IP, description, and bandwidth to assess performance.

Install the ManageEngine application manager (APM) plugin to monitor server applications, start the OPManager service, and access the web console to view apps like Postgres, SQL Server, and Tomcat.

Learn to configure and interpret performance monitors in OPManager Plus, including CPU utilization, memory usage, disk latency, and I/O in Windows Server environments using WMI, with thresholds, graphs, and alarms.

Explore the toolbar monitor in opmanager plus to view device graphs, acknowledge alerts, manage backups, and run trace routes, SSH/Telnet sessions, and remote access across routers and Windows servers.

Explore Windows service, process, and URL monitoring to track disk utilization thresholds, service status, port availability, and web applications, with alerts, polling, and discovery on the op manager platform.

Configure file and folder monitoring on Windows servers using WMI, set criteria for alerts like file existence, size, age, and modified date, and apply monitoring templates across server groups.

Configure event log monitor on Windows Server to track Active Directory, DNS, and security events, receive alarms and notifications, and enforce log on failure policies via group policy.

Learn how device templates in ManageEngine OPManager classify devices into servers, printers, switches, routers, and firewalls, and how you can define or modify templates to apply monitors across multiple devices.

Discover layer 2 maps in OP Manager Plus using CDP, LLDP, ARP, and SNMP, then view both layer 2 and VMware resources with configurable map views.

Visualize your network on Google Maps and Zoho Maps by placing devices with status icons, displaying ground distance in kilometers or miles, and configuring map providers.

Visualize data centers with the 3D data center builder to create rack and floor views, drag and drop devices, and monitor status with color codes for 24/7 access.

Explore highly customizable OPManager dashboards with over 90 widgets, drag-and-drop layouts, real-time and enterprise views, and the ability to set a personal or default home dashboard.

Create and customize dashboards by adding widgets like NetFlow traffic analyzer, health and performance, CPU utilization, and alarms, then configure a NOC view and save as default.

Configure email notifications in app manager by setting the server address, port 465, timeout 5 seconds, and ssl. Enter the sender and receiver addresses, credentials, enable ssl, test, and save.

Configure Mikrotik email notifications to alert on device issues, selecting recipients, formats, and triggers; test and refine with polls, time windows, and acknowledgment rules.

Configure Slack integration to enable real-time alerts from ops manager in your Slack workspace, helping IT admins discuss troubleshooting and make quick decisions.

Configure sound notifications in app manager to alert selected users with a chosen sound when a critical alarm triggers, and test by powering off a device to hear the alert.

Create and customize a global or device-specific notification profile to trigger email alerts for device-down events, associate devices, and tailor thresholds and polling intervals in OPManager Plus.
