Frequently Asked Questions
General
1. What can ManageEngine® Applications Manager
do?
AdventNet ManageEngine® Applications Manager helps to monitor the
performance and availability of applications such as Web applications,
application servers, Web servers, databases, network services, systems,
etc. It helps you to identify and analyze faults and performance issues
in your applications before it affects end users.
[Questions]
2. What is the difference between ManageEngine®
OpManager and ManageEngine® Applications Manager? Can they be integrated?
OpManager focuses on availability
and performance of networks (WAN, LAN, Routers, Switches, Firewalls)
and Servers and gives a device centric view. However Applications
Manager primarily focuses on performance and availability of applications
(databases, application servers, business applications etc) and servers
and gives an application centric view.
Server Management is a common functionality of the two products.
This is because it is relevant for both Network and Application
Management.
Currently Applications Manager and OpManager can be loosely integrated
by using ServiceDeskPlus
as a single console for tracking trouble tickets. Deeper integration
between OpManager and Applications Manager is present in the product
roadmap.
Have a look at the detailed discussion
about OpManager & Applications Manager in our forums.

3. Where is Applications Manager primarily used?
Applications Manager can be used in Data Centers and for managing
Enterprise IT. The data centers can be hosted by an enterprise itself
or by a service provider.
[Questions]
4. What flavours of Applications Manager is available?
ManageEngine® Applications Manager is available as Windows and Linux
downloads. Right now, we dont support Solaris version. But you can
monitor the performance of solaris host by running Applications Manager
in a windows/linux host.
[Questions]
5. What is a Monitor?
A Monitor is a specific Application, Server, Service or Web URL.
The performance of these Applications, Servers and Services are monitored
on the basis of metrics like CPU Usage, Response Time etc.
Examples of monitors supported are Windows server monitor, WebLogic
monitor, Oracle database monitor, service monitor, URL Sequence monitor,
Apache monitor etc.
For eg., If you want to monitor 100 SQL Server installations in your
network, the 100 SQL Servers will be considered as 100 monitors.
Consider the Apache web server that is used by www.appmanager.com.
This monitor (Apache web server) may have 'N' number of performance
metrics exposed. For info on what performance metrics you can see
for an Apache Monitor, refer Apache
Monitoring.
The total number of monitors, will include the monitors that we add
by default. These default monitors will not be taken into account
while calculating the number of monitors for Licensing. For licensing,
the server or web server is considered as a Monitor. CPU Utilization,
Response Time etc., are the Performance Metrics of a Server Monitor.

6. What are the different ways to monitor Custom
Applications?
-
If SNMP is enabled in that application, you
can use SNMP monitor to monitor that particular application.
Also if you have Mib for your application, you can upload that
Mib to Applications Manager and add the required attributes to
be monitored.
-
If your applications use java and exposes data
through JMX or it uses JDK 1.5 and exposes data through JMX, you
can use JMX [MX4J / JDK1.5] monitor to monitor
your application and also add required attributes for monitoring.
-
If the custom application is running in a particular
TCP port, you can use Service monitor to monitor the port
and check for availability of that port. [Service Monitoring]
-
If the application is web based application
( like IIS or Apache ), you can use HTTP-URLs and HTTP-URL
Sequence monitoring to monitor the URLs for their availability.
[Website Monitoring]
-
If you have a script in Applications
Manager machine which can monitor your application, Applications
Manager server can execute this script periodically using Script
monitor. It will also generate reports and escalate alerts according
to the results obtained. [Script Monitoring]
-
If you have a web application using JDK 1.5,
you can use Web Transaction Monitor to monitor the end
to end details about the application. [Web Transactions].
-
Windows performance counter values can
be added and monitored as attributes. Applications Manager uses
WMI for monitoring Windows Performance Counters. [Windows Performance Counters]
[Questions]
7. How does Applications Manager monitor machines
with multiple-CPUs?
ManageEngine
® Applications Manager monitors the overall CPU usage of
the server (not individual CPUs).
Win32_PerfRawData_PerfOS_Processor
class is used to get the required CPU data in WMI mode of monitoring.
[Questions]
8. Are Features / enhancements provided specific
to a customer?
We have a cumulative customer patch mechanism that ensures all customer
patches get integrated into the immediate Service Pack of the product
- which is normally in 1 or 2 months.

Enterprise Edition
9. How to identify
when to switch over to Enterprise Edition?
Each installation of Applications Manager can normally support
monitoring 250 monitors (servers and applications on a 1 CPU,
1.8 GHz, 512 MB RAM, RH Linux). This could go higher based
on the hardware configuration of the server on which Applications
Manager is deployed and based on the load of the monitored server.
The "Load Factor" should help you decide when its time
to go for a distributed setup.
[The load factor follows the format x.y, where
'x' represents load on Applications Manager Server, while 'y'
represents the load on the Database used by Applications Manager.
A value of zero represents least loaded, while a value of nine
represents most loaded.]
[Questions]
10. What are the limitations of Enterprise Edition?
You can view all reports and real time stats from a single console
in the Admin Server. But to configure, you will have to login to
the Managed Server Web Console. However it is made easy providing
the ability to 'jump' from the Admin Console to the Managed Server
console.
More Information on Enterprise Edition can be got from Enterprise
Edition Product FAQ.
