Enterprise Edition Admin Server is the master server through which you will be able to view consolidated data of all the Managed Servers.
During installation, you need to:
The Managed Server automatically gets registered with the Admin Server when it starts up. In case you want to edit the configuration, go to Admin tab. Click on Managed Servers link. This will take you to the Managed Server page from where you can configure the Managed Servers. Alternatively, this can be done by clicking on the Managed Servers link just below the main tabs.
Here is how you can configure a Managed Server:
The following managed sever details are displayed in the table:
You can select one or more Managed Servers and click the Download Now link at the bottom of the table to download the Service Pack and the Upgrade Now link to upgrade the Service Pack.
In order to find if a particular Applications Manager installation is heavily loaded you can use the Load Factor, which is provided in the 'Support' tab under the 'Applications Manager Installation Information' category. 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. Hence Load Factor can take values from 0.0 to 9.9 (heavily loaded). The Load Factor of each of the Managed Servers is also displayed in the Admin server under the "Managed Servers" option and you can use the same to distribute load evenly among the Managed Servers.The Load Factor can be denoted by x.y where x represents Managed server polling load factor and y represents Managed server data base load factor.
Applications Manager Enterprise Edition allows you to add monitors and group them from the Admin Server in a distributed setup. To add a new monitor in a host, refer these links.
However, while adding a new monitor from an Admin server, the managed server under which the monitor is to be added can be selected manually by the user or using load factor by Applications Manager. The value for Maximum monitors allowed per Managed server can be configured in AMServer.properties. The key is am.max.monitorcount.mas and default value is 500.
Selecting Managed Server Using Load Factor:
You can select one of the following options in the Add Monitor Page:
Selecting Managed Server Specified by the User:
The user can select the managed server. This will add the monitor directly to the selected managed server irrespective of load factor and monitor count.
Certain resources can be monitored from managed servers running in the same domain/ geographical location as the resource. Load factor calculation across all the distributed managed servers can result in the addition of a monitor in a server located in another domain (since the load factor condition matches). Grouping managed servers in the same area gives the user the option to use load balancing within the group of managed servers.
Creating a Managed Server Group:
Various monitors in Managed Servers can be grouped and a consolidated view can be obtained in Admin Server. For eg., consider a set up that has three Managed Servers and one Admin Server. Each Managed Server has 200 monitors which includes 10 windows servers. If you want to monitor the windows servers in all the three managed servers as a group, then you can create a new Monitor Group in the admin server.
You can create Monitor Groups by following the steps in Create Monitor Group help document. Once you have created the Monitor Group, the next step would be to associate the required monitors from Managed Servers to the Monitor Group in the Admin Server. After the setup is done, you can configure the alarms for the Monitor Group. Currently, only EMail and SMS alarm actions are supported.
Fetch Data: There is an option to fetch the data from the managed servers at the given instant, instead of waiting for the poll to happen.
Edit: You can edit the managed server details using this option.
Enable/Disable: You can enable/disable data collection in the Managed Server. Note that when you disable, data collection will still take place, you only stop syncing with the managed server.
Admin Email Settings: An EMail can be configured to be sent once a Managed Server goes down and also once every 24 hrs till the Managed Server is up again. The EMail setting is available in the Admin EMail Settings" option under the "Admin" tab. The option to enable/disable this EMail, is available in the "Edit" option of the respective Managed Server.
When you login to the Admin console, Graphs and images displayed for a monitor are retrieved directly from the corresponding Managed Server itself and are displayed in the Admin console. These graphs/images cannot be retrieved, if the Admin Server is accessible from a particular machine/over the Internet and the Managed Server is not accessible.
In this case, select the "Proxy Managed Server request through Admin Server" request option. This will result in the images/graphs being fetched to the Admin Server from the Managed Server first and then the image from the Admin Server is viewable in the Web Browser.
E.g., Admin Server is running as part of IDC and accessible via the Internet (From a machine say "ClientMachine") but the Managed Servers are not accessible (from "ClientMachine") this option should be enabled.
In the Enterprise setup, the User Administration module functions independently in the Admin Server and Managed Server. Hence, a user-based view assigned in the Managed Server will not reflect in the Admin Server and vice-versa. Since, you will be viewing the data collectively from the Admin Server, you need to assign owners to the various Monitor Groups of the Managed Server in the Admin Server. Of course, if it is assigned in the Managed Server it will function independently. Also, in the Manager Console (SLA Management console), you can assign SLAs and associate actions to be invoked for SLA violation to the Monitor Groups in the Admin Server.
Click on the Jump To link in the Admin Server just above the toolbar, which brings down a list of the Managed Servers. Clicking on any of the Managed Server names in the list will take you to the web console of the respective Managed Server in a separate browser Window.
ENTERPRISEADMIN role is used for logging into the Managed Server from Admin Server for data synchronising. The username for this role is systemadmin_enterprise and the password is the regular ADMIN role password. This role is not exposed in the UI, it will be used internally.
Visit our Enterprise Edition FAQ page for more details on when and how to set up the Enterprise Edition.
The following two things are used to select the managed server automatically:
If the condition is not matched then we show the "No Managed server is available" message to the user.
