Some FAQs regarding Network Discovery
1.How does "Network Discovery" function work? How to discover the network? Eg.Through what mode?
Initially Applications Manager get 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.
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 finsh 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.
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.
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.
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.
