2.2. Network License Manager Dialog Box
The functions of the GNLM tool are divided into five major categories: Home , Data Statistics , License Management , Permission ,
and Troubleshooting . For details, please refer to the tabs on the left side of the tool interface.
2.2.1. Real-time Authorization Data
When GNLM is started, the system will automatically start reading data from the authorization server and display the information on the Home interface.
You can see the usage of the authorization number at the current time point. When the mouse is placed on the bar data, specific information will be displayed, including "Unused Nodes", "Floating Nodes" and "Rent Nodes".
2.2.2. Authorization Data Statistics
On the Statistics page, you can view node activation (interval data), node usage (usage duration) and authorization failures (Activation failures) in a certain time period.
2.2.2.1. Interval Data Statistic
On the Statistics → Interval Data page, when multiple products are activated on the server at the same time, all data will be displayed in a table by default, which will make the data look confusing. In this case, you can use the product filter to select one or more products to view the data.
2.2.2.2. Usage Duration Statistic
The time when each user starts and closes the software will be recorded in Data Statistics → Usage Duration . This data can be used to view the time that users use CAD.
There are icons in the upper right corner. The Yellow data bar indicates that this user has obtained the authorization through renting, and the Blue data bar indicates that this user has obtained the authorization through floating. Detailed information will be displayed
when the mouse is placed on the data bar.
You can also use the date or version filter to view the length of time users have used CAD within a certain period of time.
2.2.2.3. Activation Fail Statistic
In some cases, users may fail to obtain authorization from the server. There are many reasons for the failure, such as the nodes have been used up, blacklisted, etc. Through this page, the administrator can see the detailed reasons for the user's failure to
obtain authorization, which is convenient for making the next decision.
2.2.2.4. Authorization Data Export
In addition to visual data monitoring in the interface, the system also supports data export. The export button is provided in the upper right corner of the three interfaces mentioned above to support data export. Currently, only general export is provided which
directly exports the data type of the relevant page. The exported data is relatively basic and requires some time to analyze the data.

2.2.4. Permission Settings

It is not mandatory to enter all items, but at least one item of information must be entered. It is recommended to fill in all the items.
This tool supports exporting the entered user information to ensure that the information can be reused. At the same time, the information can also be directly imported into the tool to avoid repeated data entry.
2.2.4.3. Create Multiple Users as a Group (Optional)
Click Group Management → Add button to create a named group for the specified users. After the group is created, it can be
edited, including adding users to the group, removing users, etc. In this way, you can set permissions for users in the group in
batches. This step can be performed according to actual conditions and is optional.
2.2.5. Permission Assignment
After adding the users' information, you can set permissions for the users. You can check/uncheck to allow/prohibit the user from obtaining authorization. After setting, click Apply and the permission setting will take effect.
2.2.6. Reserved Nodes
In scenarios with tight authorization resources, when the quota for authorization nodes configured by the enterprise cannot meet usage demands, designers may be unable to obtain authorization, which can affect their work. GNLM's node reservation mechanism pre-allocates a specific number of authorization resources to core users or key user groups. This ensures that when system resources are overloaded, priority is given to personnel in important positions, allowing them to continue obtaining the authorization and maintain uninterrupted operation of design tasks.
Click Permission Settings → Reserved Nodes , you can select the product type, number of reserved nodes, and user information, and click the "Add" button to add the reserved information to the table.
If you need to set multiple reservation information, repeat the above steps. After the settings are completed, click Apply . When the
"Read Successful" prompt appears at the top of the page, it means that the node reservation is successful.

2.2.7. Timeout Settings
You can set the automatic release time of authorization. When the user does not use the software for a set period of time, the system will automatically reclaim the nodes occupied by the user. If the user does not run the product within the specified time, the user will be judged as an invalid user. The nodes of invalid users will be automatically revoked when there are insufficient nodes, and authorization resources will be allocated to active users first.
You need to check "Enable timeout settings" to set the timeout period.
2.2.8. Troubleshooting
Trouble shooting is an automated inspection tool developed based on our experience in handling user authorization issues. It provides automated detection services. The system scans abnormal usage data and generates diagnostic suggestions to help you quickly locate the root cause of the problem.
Currently, three analysis methods are provided: Quick Diagnosis , Depth Diagnosis and Comprehensive Diagnosis , which can provide two analysis results: "The following users have lower versions occupying higher version authorizations" and "The following users occupy multiple nodes on one machine".
In the future, as this tool version is updated, more analysis results will be provided to cover more usage scenarios.
Quick diagnosis : Troubleshoot problems by checking the current data on the server.
Depth diagnosis : Troubleshoot problems by checking historical data in the logs.
Comprehensive diagnosis : A combination of the above two diagnostic methods, involving a comprehensive analysis of data and troubleshooting.
