The Add / Discovery section consists of the following tabs:
In the Add tab, you can create a new monitor (i.e) discover the Monitor from the network and start collecting monitoring data. Learn how to create a new monitor
Using the Bulk Import capability, you can add monitors of the same type in bulk. Bulk import of monitors is performed by using a .csv file which contains all the configuration details of the monitor you wish to add. Learn how to perform Bulk Import of monitors
Network Discovery is the process of discovering all Monitors in a specified network. It discovers monitors running in the default port only.
To discover all the monitors in a network:
The Network Discovery tab is displayed once the discovery process is completed. Here you can view the list of various devices (servers & applications) that have been discovered in Applications Manager. Also, there is an option to View Application Dependency Maps. In View Application Dependency Map page, you can create a monitor group among the applications discovered through the ADDM by enabling the 'Use Application Dependency Mapping (ADM)' option. If disabled, you can create a monitor group by associating monitors manually to it.
You can perform various operations to the required discovery profiles by selecting appropriate options given below from the Network Discovery table:
Besides the Network Discovery table, you can view Dependency Maps created with the discovered resources under the Dependency Map table. This table shows the list of various dependency maps created along with the number of servers and applications added to this map view. On clicking the map name, you can find a visual map view of all the servers and their associated applications that are available and connected to each other. There are two types of dependency maps that can be viewed:
Also, you can create a new map view by clicking over the Add New link.
Question 1: How does "Network Discovery" function work? How to discover the network? Eg.Through what mode?
Initially, Applications Manager gets all the Ip addresses in the given domain and then Applications Manager discovers them by using ping test. If the ping test succeeds and if SNMP agent is running on that machine, Applications Manager will try to add it to the appropriate category ( i.e., windows / linux / solaris ) and collect data, otherwise Applications Manager will add that server to unknown category.
Question 2: If I add a new "Network Discovery", does it only discover once or discover at regular intervals? Because there are only "Add New" and "Disable Network Discovery" buttons, I don't know when it will start to discover and when it will complete discovery.
When you add Network Discovery, it will rediscover the network every time you restart Applications Manager and also it will do rediscovery once in every 24 hours. Once you start network discovery, it will start discovering the servers in the network. It will wait for 20 seconds interval between discovering servers.
Question 3: I find "Network Discovery" can find a small part of the monitors in the network only, there are lots of monitors that can't be found.
In the professional trial version of Applications Manager, only 50 servers are discovered using Network Discovery.
Question 4: I don't want to monitor a certain monitor, I delete it manually; but I don't disable network discovery, will it be discovered and monitored again?
Yes, it will discover that monitor again in the next rediscovery which takes place after 24 hours.
Services - Using this option, you can choose which of the services needs to monitored by default.
The services are listed down along with their default ports. For eg., if you had already added a Windows Server monitor, by using this option, you can choose the services (that are running in that windows server) to be monitored. You choose to monitor all the tomcats & IIS servers that are running in the windows server. Data Collection does not happen for services that are not enabled, thereby increasing the efficiency of monitoring in general.
By using the edit option, you can edit the port number. If there are multiple ports, enter the ports as comma separated.
