Discovery Tasks

discovery tasks discovery tasks discovery is a service that you can run to find devices in your network discovery uses a set of configuration criteria that you can specify to determine which network entities to monitor creating separate discovery configurations offers you more flexibility for customizing the discovery and monitoring by providing separate configurations, you can discover limited portions of your network by performing several smaller discovery operations instead of performing one large discovery operation filter and export the results of a discovery session in different ways monitor only the required parts of your network to be able to update your network environment within your scheduled period track your network entities when you discover your network, you must have knowledge of all the network devices you plan to discover, also including the following information if necessary ip addresses for all addressable devices(obligatory) list of all devices router addresses collector snmpv1/v2c snmp community strings snmpv3 security credentials ssh credentials discovery info discovery info is the first step of the discovery process which contains various inputs to be filled to determine which devices will be discovered there are three options to choose from to set the ip address or addresses of the devices that will be discovered, detailed information of these preferences will be given below first step of each selection is setting a discovery name so it’s easier to find the discovery process on further configuration of the process then to set the ip addresses of the device or devices (depending on your selection) that will be discovered last step is defining the collector which will be listening the ip block single host first alternative is to choose the single host option which is useful to discover a single ip address ip range then second option is to choose the ip range method which can be used for scanning a whole ip block or a section of a network import from file finally, import from file option, here single monitor will take all the ip addresses that are in an excel file however, it is a must that this excel file only consist of ip addresses but anything else which must be entered horizontally you can import one or more single ipv4 addresses, ipv4 ranges, single ipv6 addresses or more discovery options discovery options is the second step of the discovery process which contains credential customization options user can pick, create or customize credentials on this stage and credentials that are designed beforehand will be listed on this page on a multi ip discovery if there are devices taking different credentials single monitor will try to match all the credentials selected for each device then it will only show matching ones furthermore, there are additional options that might become handy for some situations add credential it is possible to add four types of credentials on this screen which are snmp v1 v2, snmp v3, ssh and telnet to be able to fill these credentials user must know all required credential parameters skip access credential if icmp down this check box option can be used to skip credential checks if a device is not responding to icmp protocol, so to optimize the discovery process duration add devices automatically when this option is ticked single monitor adds the devices and their monitors automatically to the single monitor database if you want to adjust your monitors and set your device type manually this option is not suggested however, it is also possible to customize these monitors from monitoring section when checked, this option will pop up a small choice screen where user must determine how they would like to customize the process and adjust it according to their needs when clicked this option will bring a small pop up screen for determining which devices to add automatically according to available credentials initially there are two options to chose from which are “add if all of access credentials is up” and “add if any of access credentials is up” these options are based on “and” and “or” logic gates respectively then there are three credentials to choose from icmp, snmp and ssh so, when a user marks the “add if all of access credentials is up” option and the credentials they would like to select, here sm will only automatically add devices that are responding to all the access credential selected however, if user selects the “add if any of access credentials is up” option, here sm will automatically add every device that is responding to any of the selected access credentials condition credentials add any add all icmp snmp ssh case 1 ✔ ✔ ✔ case 2 ✔ ✔ ✔ case 3 ✔ ✔ ✔ case 4 ✔ ✔ examples results case 1 sm will add all the devices responding to icmp or ssh protocols regardless of each other case 2 sm will add all of devices responding to icmp or snmp protocols regardless of each other case 3 sm will only add devices that are responding to both icmp and snmp credentials case 4 sm will only add devices that are responding to ssh credential assign devices to group when checked a table will pop up where users will be able to assign devices to device group or groups if necessary, it’s possible to create the device group needed from this screen delete devices automatically this option is for deleting devices that becomes unreachable for the credentials below if marked delete if icmp is up this option is for deleting devices that becomes unreachable for icmp delete if snmp is up this option is for deleting devices that becomes unreachable for snmp delete if ssh is up this option is for deleting devices that becomes unreachable for ssh add devices in maintenance mode with this feature a user will be able to add devices in maintenance mode for specific period (up to 24 hours) that user determines schedule scheduling options defines whether to activate certain configurations on a routine basis using a schedule there are five options to choose from for creating a schedule which will be explained in detail below also, there is an available option to proceed without a schedule on the left corner of the schedule screen displayed as a check box note in a network environment that located in multiple time zones, schedules are executed according to the local time of each server’s location once for this scheduling option user must set a date and a time of the day for discovery to run daily for this scheduling option user must set an exact time of the day for discovery to run on daily basis weekly for this scheduling option user must set a day of week and exact time of the day for discovery to run on weekly basis monthly for this scheduling option user must set a day of month and exact time of the day for discovery to run on monthly basis yearly for this scheduling option user must set a month day and exact time of the day for discovery to run on yearly basis
