7. Windows vs Linux WMI monitors not supported in Linux installation
Exchange Server, Active Directory, SQL Server monitor are supported in Windows (as it uses WMI).
Plug-in modules like NFA, NCM are supported only in windows installation.

8. Windows Installation
The user, which is used to install OpManager, should be an Administrator or should belong to the Administrator group.
Install as a Windows Service
You can choose to install as Windows Service during installation or run OpManagerService.bat under <OpManager-Home>/bin folder
Disable Windows Firewall
To avoid connection problem to remote device
Disable Anti Virus
Corrupts database.

9. Windows Installation Disable SNMP Trap Service
Disable User Access Control in Windows 7
Install Putty to troubleshoot SSH monitors
Install net-snmp to troubleshoot data collection problems in SNMP
Date/Time should be set to the current date and time.

10. Linux Installation
On a Debian OS, iputils-ping package should be installed.
It is preferred to use the default installation folder, as the necessary file access privileges are automatically set to this folder. The default installation folder is /opt/ManageEngine/OpManager. Else, you have to use the following command to provide the privilege
# chmod –R 755 [full-path-to-installation-directory]

11. Linux .. Stop ipchains and iptables daemons Stop snmptrapd service.
MySQL is the preferred database. If you choose to use your MySQL instance for this, ensure that the version is supported by OpManager. OpManager uses Version as its default MySQL version. You can also choose to have MSSQL as the preferred database though the installation is on a Linux box.

12. High Availability
Install Standby Engine

13. Discovery & Monitoring
Ensure that the SNMP is enabled and configured on the Network Devices like routers, switches, firewalls, load balancers
Ensure the devices accept SNMP Packets from OpManager host
Configure Trap Destination as OpManager host and port.

14. SNMP Config Example

15. Example ..

16. Example .. To set OpManager as host:
Run the following commands from the command prompt:
#configure terminal
#snmp-server host <OpManager server running system's IP> <Trap community string> snmp
(example: snmp-server host public snmp)
#end
#copy running-config startup-config

17. Device Templates
The templates carry the information required to classify the devices and to associate relevant monitors
OpManager comes with over 600 device templates
Add your own device templates
Admin  Device Templates lists all the out-of-the-box templates
Click “Add New” to add your own template

18. Adding New Device Template

19. Configure Interface Templates
Enable\Disable monitoring of Interfaces
Enable\Disable metrics to be monitored in specific interface types

20. Credential Manager
Helps to manage credentials used for monitoring the devices
SNMPv1/v2c, v3, Telnet, SSH, WMI protocols
As a best practice have a separate account for monitoring the device

21. Add Credential for SNMP v1/v2

22. Rule Engine
Helps to automate the process of adding monitors to the devices
Say for example you want to add “httpd” process monitor whenever a Linux device is discovered
Go to Admin Rule Engine
Add a New Rule, Select Device Type and criteria as “linux”
Select add process monitor and select “httpd” process monitor

23. Initiate Discovery Admin Discover Devices
Specify the network range to discover
Discover the devices in that network, classify devices based on Device Template and associate the matched credentials to the device
Import the devices from a csv file

24. Discovery … You can use the seed.file to drive the discovery process.
A couple of examples have been shown below.
Example 1 :- Do not discover a subnet.
In order not to discover a subnet,
you have to use the following syntax in the [OpManager-Home]\conf\seed.file
<NOT_TO_DISCOVER>
NETWORK_ID="X.X.X.X" NETMASK="Y.Y.Y.Y" /> NETWORK_ID="Z.Z.Z.Z" NETMASK="W.W.W.W" />
</NOT_TO_DISCOVER>
Where "X.X.X.X " and "Z.Z.Z.Z" are the network addresses which are not be discovered.

25. Maps & Topology
Create as many business views as you need, so as to export them to visio for immediate reference.
Create Business view based logins, so as to provide role based logins and views.
Keep the list view a tabular one, so that the page loads faster and also gives a quick view on the performance of the device.

26. Alarms
Configure Threshold profile for different monitors and different categories
Identify the various Alert profiles you want to configure
Configure Modem SMS Alert Profiles where you need the immediate attention of your Network or Server Administrators.
Use Quick Configuration Wizard to associate the notification profiles to devices

27. Alarms
Step 1: Choose the option “Assign notification profile…. “ in Quick Configuration Wizard
Step 2: Choose the Notification Profile
Step 3: Choose the criteria for such a profile
Step 4: Choose the time window at which this profile should be active
Step 5: Choose the category or business view to which this profile has to be associated with.

28. Alarms
Use Rooster based alert profiles so that you don’t get spammed with informational or warning alarms on Weekends
You can configure Alarm Escalation to receive notification on critical alarms, which have not been acknowledged or resolved until the next polling time.
Configure Device Dependencies in order to suppress related alarms from devices, dependent on router or switch or firewall.

29. Alarms
Add Notes to alarms so that this serves as a knowledge base item for other technicians.
Use Log-a-ticket profile to integrate with ServiceDesk Plus, that offers ITIL workflow
Forward Traps to other EMS’s if you have a single console to collect traps. You can include the ipaddress of the trap receiver and trap port in [OpManager-Home]\conf\trap.forwarder file

30. Reports Configure Reports to be scheduled on a periodic basis.
Use HTML for such configured report s and choose to publish such reports, than to receive them as attachments.
It is easier to manage the reports on a business view criteria.
You can rebrand OpManager in order to use your own logo in the Reports

31. Schedule Reports Select Reports
Generate reports based on Business View

32. Performance Tuning Increase JVM Memory
OpManager Java Heap Size can be increased based on optimization requirements by editing the value of -Xms/-Xmx parameter in StartOpManagerServer.bat/sh script or by editing the file /opmanager/conf/wrapper.conf (Initial/Maximum Java Heap Size).
You can use 25% of RAM in the system as maximum Java Heap Size. Say for example in a 2GB RAM, give –Xmx as 512 MB.

33. MySQL Tuning You can configure these MySQL parameters
with the required values in /opmanager/bin/startMYSQL.bat script.

34. Performance Tuning
Configure polling interval depending upon the type of the device
Configure Downtime Scheduler in order to unmanage devices during scheduled downtimes.
Change the WMI threads for data collection, change the WMI_EXEC value in [OpManager_Home]\conf\threads.conf file.

35. Secure Web Access
Follow the steps below to enable https login for OpManager Web interface.
1) Open a CMD prompt and go under /OpManager/bin
2) Execute ssl_gen.bat -f Enable
This will enable the self-signed SSL certificate for OpManager.
OpManager web client can be accessed in the same port number with
You can also generate the Certificate and import in to OpManager
