![]() This probe retrieves system and traffic information from an SNMP-enabled device. It can take up to 9 seconds to change a device status to DOWN. When the probe reaches the device's limit of the number of pings to send (as determined by the device or map's limit) without receiving a response, the device status is changed to DOWN.īy default, the number of echo requests is 3 and the default timeout is 3 seconds. If no response is received within the specified time, Intermapper re-sends the echo request and waits again for the specified Timeout. Intermapper sends the ping packet and waits for a response for the specified Timeout. To send the same IP packet size to an IPv6 target, set the number of data bytes to 1452. Tip: To send a 1500-byte IP packet to an IPv4 target, set the number of data bytes to 1472. This value is between 16 bytes and 2000 bytes.ĭata Pattern - the hexadecimal pattern repeated throughout the payload contents. Number of Data Bytes - the number of bytes of ICMP data to send. This probe sends an ICMP echo request packet to the target device to determine if it is active and responding. Password - The password of the specified user. Username - A user name that has read-permission on the map. Map Name - The name of the map on the remote server. You can also create a device using the DNS name or IP address of the Intermapper server containing the map or localhost for a local map. The easiest way to use this probe is to drag a map from the Map List to another editable map. Double-click the device to view specified map. Intermapper periodically queries the specified map and sets the device status to the status of the worst item on that map. This probe allows Intermapper to monitor the state of a map running on an Intermapper server. After a valid SNMP response is received, Intermapper sets the device's probe to SNMP. Intermapper sends an SNMP GetNextRequest for the sysName, sysObjectID, and sysServices OIDs (1.3.6.1.2.1.1.5.5, 1.3.6.1.2.1.1.5.2, and 1.3.6.1.2.1.1.5.7, respectively) using the specified SNMP read-only community string. If it does not, the probe is set to Ping/Echo. This probe checks if the device responds to SNMP.
