The String Man : His Road to Discovery

If you use other user accounts, interfaces, or nodes, you might not see all of the options in the way described here. If you use a cluster installation, note that failover nodes are read-only by default. Add Auto-Discovery Group Settings. Group Name and Tags. Enter a meaningful name to identify the group. The name will be shown by default in the device tree and in all alarms. Enter one or more tags. Confirm each tag by hitting the space, comma, or enter key. You can use tags to group objects and use tag-filtered views later on.

Tags are not case sensitive. Tags are automatically inherited. Select the method for automatic network discovery. This option is only visible if you enable using specific device templates above. Choose one or more templates by adding a check mark in front of the respective template name. You can also select and deselect all items by using the check box in the table head. PRTG will use the selected templates for auto-discovery on the current device. Once the auto-discovery is finished, PRTG will create a new ticket and list the device templates that it used to create new sensors.

The ticket will not show templates that were not applied. Define when PRTG will run the auto-discovery. The Discovery Schedule will be set to Once on all devices created by the scheduled auto-discovery for performance reasons. Define how you want to define the IP range for auto-discovery. Only subnets with up to 65, IP addresses can be discovered! If you define a range with a higher number of addresses, discovery will stop before it is completed.

Deadliest Catch

This field is only visible if you select Class C network detection above. Enter a class C network as IP base for the auto-discovery. Enter the first three octets of an IPv4 IP address, for example, This will complete the IP base above to an IPv4 address. For example, enter 1 to discover from For example, enter to discover up to This field is only visible if you select the IP list option above. Enter each address in a separate line. IPv4 and Subnet IPv4. This field is only visible if you select the IP and subnet option above. You can also use the short form like PRTG will scan the complete host range without network and broadcast address defined by the IP address and the subnet mask.

IP with Octet Range. This field is only visible if you select the octet range option above. Enter an expression in the format a1. All permutations of all ranges are calculated. This field is only visible if you select Active Directory above. If you leave this field empty, there will not be any restriction. Make sure that the OU contains computer accounts. If the OU is empty, you will receive an error message. Do not enter the domain components. Define how to monitor newly discovered devices. This affects only new devices. The setting for existing devices will remain unchanged. We recommend that you use the default value.

This setting does not affect how PRTG shows the devices in the device tree. Define if you want to add devices that already exist in your PRTG installation also to the currently selected group. In certain cases, the IP resolution may not work and might result in a device not being added if it has the same local IP address as in another LAN. By default, all following settings are inherited from objects higher in the hierarchy and should be changed there, if necessary. Often, best practice is to change them centrally in the Root group's settings, see section Inheritance of Settings for more information.

To change a setting only for this object, disable inheritance by clicking the button next to inherit from under the corresponding setting name. You will then see the options described below. If you have not set credentials yet, set them now before starting the auto-discovery to fully exploit the power of this feature! Credentials for Windows Systems. Click to disrupt the inheritance. See section Inheritance of Settings for more information.

Domain or Computer Name. Define the authority for Windows access. If you want to use a Windows local user account on the target device, enter the computer name here. If you want to use a Windows domain user account recommended , enter the Active Directory domain name here.

Do not leave this field empty. Enter the username for Windows access. Usually, you will use credentials with administrator privileges. Enter the password for Windows access.

Define the authentication method to use for login. This field is only visible if you select password login above. This field is only visible if you select private key login above. Paste a private key into the field OpenSSH format, unencrypted. If you do not insert a private key for the first time, but change the private key, you need to restart your PRTG core server service in order for the private key change to take effect! For details, see section Monitoring via SSH. Define the protocol to use for WBEM. This setting is only relevant if you use WBEM sensors.

Define the port to use for WBEM. This setting is only visible if you enable manual port selection above. Enter the WBEM port number. Enter the port number to use for SSH connections. By default, PRTG uses this setting automatically for all SSH sensors , unless you define a different port number in the sensor settings.

Define the rights that you want to use to execute the command on the target system. This field is only visible if you choose sudo or su above. Enter a username to run the specified command as a user other than root. If you leave this field empty, you will run the command as root. Ensure you set the Linux password even if you use a public or private key for authentication. This is not necessary if the user is allowed to execute the command without a password. This field is only visible if you choose to run the commands using su or sudo with password above.

Enter the password for the specified target user. Select the method you want to use to access data with SSH sensors. We strongly recommend that you keep the default engine! For now, you still can use the legacy mode to ensure compatibility with your target systems. Enter a login name for access to VMware and Xen servers. Enter a password for access to VMware and Xen servers.

See the manual sections for VMware sensors for details. Define the protocol used for the connection to VMware and XenServer. Define if you want to use session pooling for VMware sensors. Credentials for Database Management Systems. The settings you define in this section apply to the following sensor types: Define which ports PRTG will use for connections to the monitored databases.

If you choose the automatic port selection, PRTG uses the following default ports: Enter the number of the port that PRTG will use for database connections. Please enter an integer value. All database sensors on this device will use this port to connect. Select the authentication method for the connection to the SQL database. This field is only visible if you select SQL server authentication above. Enter the username for the database connection.

Enter the password for the database connection. Enter a timeout in seconds for the request. If the reply takes longer than this value defines, the sensor cancels the request and triggers an error message. The maximum timeout value is seconds 5 minutes. Credentials for Amazon CloudWatch. Please see the corresponding Amazon CloudWatch sensor documentation to learn more about the rights that are required for querying AWS CloudWatch metrics.

Select the SNMP version for the device connection. When using SNMP v3 you can only monitor a limited number of sensors per second due to internal limitations. The limit is somewhere between 1 and 50 sensors per second depending on the SNMP latency of your network. This means that using an interval of 60 seconds limits you to between 60 and SNMP v3 sensors for each probe.

If you experience an increased Interval Delay or Open Requests with the Probe Health sensor , distribute the load over multiple probes. SNMP v1 and v2 do not have this limitation. This setting is only visible if you select SNMP version v1 or v2c above. Enter the community string of your devices. This is a kind of "clear-text password" for simple authentication.

This setting is only visible if you select SNMP version v3 above. The type you choose must match the authentication type of your device. If you do not want to use authentication, but you need SNMP v3, for example, because your device requires context, you can leave the field Password empty.

Enter a username for secure authentication. This value must match the username of your device. Enter a password for secure authentication. This value must match the password of your device. Select an encryption type. They lack RFC specification. The type that you choose must match the encryption type of your device. Enter an encryption key here.

If you provide a key in this field, SNMP data packets are encrypted using the encryption algorithm selected above, which provides increased security. The key that you enter here must match the encryption key of your device.

If the key you enter in this field does not match the key configured on the target SNMP device, you will not get an error message about this! Please enter a string or leave the field empty. Enter a context name only if it is required by the configuration of the device. Context is a collection of management information accessible by an SNMP device. Please enter a string.

Enter the port for the SNMP communication. If the reply takes longer than the value you enter here, the request is aborted and an error message is triggered. The proxy settings determine how a sensor connects to a given URL. This setting affects monitoring only and determines the behavior of HTTP sensors. If you leave this field empty, no proxy will be used. Enter the port number of the proxy.

Often, port is used. If the proxy requires authentication, enter the username for the proxy login. Only basic authentication is available! If the proxy requires authentication, enter the password for the proxy login. Define which user group s will have access to the object that you are editing. A table with user groups and rights is shown; it contains all user groups from your setup.

For each user group, you can choose from the following access rights: You can create new user groups in the System Administration—User Groups settings. If you leave the current page, all changes to the settings will be lost! While auto-discovery is running, you may experience a lower system performance than usual, because PRTG works in the background to discover your network.

Depending on the IP ranges defined up to 65, addresses , the discovery may run up to several days before it is complete. You can review the status of the discovery process as follows:. This may be useful for performance reasons or if you prefer to manually add devices and sensors to your installation.

Auto-Discovery The PRTG auto-discovery is a great way to automatically create a sophisticated and concise set of sensors for your complete network. Part of the criticism was that in naming the new species, Leakey brashly changed the definition of Homo so that pre-Zinj would qualify. By this standard, pre-Zinj was something of a pinhead, with a brain of just cubic centimeters the average human brain has a volume of 1, cc.

Other discoveries that Leakey made in the s also generated controversy.

On an island in Lake Victoria, he found fossil evidence of two new primate species that he said pushed back the origins of human beings by millions of years. His claims were immediately met with harsh criticism. One species was 20 million years old. Experts disputed the claim then, arguing that it was a fossil ape, which remains the prevailing view. Its pedigree is checkered. Leakey first said it was more ape than human, but later modified that view. Scientists now believe that it is the most advanced fossil ape of its period in East Africa. A six- to seven-million-year-old skull, found in Chad by paleoanthropologists from France, is older and yet appears more modern in several key respects than specimens from more recent times.

Those features, plus its discovery far from Kenya or Ethiopia the other leading candidates for the place where human beings split from the common ancestor we share with apes are prompting experts to reconceptualize the human family lineage. By the late s, Leakey was little involved in fieldwork, partly because of ill health but also because he was devoting so much time to raising money for the many research endeavors he oversaw.

He was, however, directing a dig at Calico Hills, east of Los Angeles. Hundreds of stone flakes had been recovered from the site, and the excavators believed them to be human artifacts. That was an extraordinary claim because the site was as much as , years old, and most anthropologists believe that humans came to the Americas no earlier than 30, years ago, and probably much more recently.

Yet despite his occasionally misplaced enthusiasms, Leakey remains a seminal figure. But, given the time [in which] he was working, overall his instincts were right. The specimen was named But on October 1, a few days after holding the fossil in his hands, Louis Leakey died of a heart attack on a visit to London.

Thirty years later, the debate that he anticipated continues. Subscribe or Give a Gift. Humans Reached the Roof of the World 40, Years. Learning to Speak Latino. Science Age of Humans. A New Treatment for Blindness. America's Most Revolutionary Artist. At the Smithsonian Visit.
