If InterMapper reaches that limit without receiving a response, InterMapper declares the device to be down. Each device has a limit of the number of pings to send (determined by the device's limit or the map's limit). If no response is received after that time, InterMapper re-sends the echo request, waiting again the device's Timeout. The time it waits is determined by the device's Timeout. InterMapper sends the ping packet, then waits for a response. 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. Data Pattern specifies the hexadecimal pattern that is repeated throughout the payload contents. ![]() The mimimum value permitted is 16 bytes the maximum is 2000 bytes. Number of Data Bytes specifies the number of bytes of ICMP data to send. The Ping/Echo probe sends an ICMP echo request packet to the target device to determine if it is active and responding. Password is the password for the corresponding username. Username specifies a user name that has read-permission on the map. Map Name specifies the name of the map on the remote server. Then select Map Status for the probe type, and configure it with: To make a device with the "Map Status" probe, create a device with the DNS Name or IP address of the InterMapper server being monitored (or "localhost" if it's a local map) when adding the device to the map. Double-clicking the icon with InterMapper Remote opens a window with the remote map and brings it to the front. InterMapper periodically queries the specified map, and the icon displays the status of the "worst" item on that sub-map. This probe allows InterMapper to monitor the state of a map running on another InterMapper server. If a proper SNMP response is received, InterMapper sets the device's probe to be SNMP otherwise, InterMapper sets the device to use a Ping/Echo probe. InterMapper sends a 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. ![]() The Automatic probe attempts to determine whether the device speaks SNMP or whether simply to ping the device.
