Before you begin
Before you run BMC PATROL Agent License Utility, ensure the following prerequisites are met:
- PATROL Agent is installed on every host from which you want to collect information.
 - One of the following files is stored on the host on which the PATROL Agent License utility is installed:
- agents.ini: If you have installed PATROL Configuration Manager, use the agents.ini file. Copy the file to the <install_dir>\PATROL Licensing Report directory.
 HostList.csv: If you have not installed PATROL Configuration Manager, create a file named HostList.csv. The HostList.csv file must include the following information about the PATROL Agent hosts.
- Host names or IP addresses
 - Port numbers
 - Group names: This is a logical entity that is used to combine the PATROL Agents that have common credentials into a single group.You must provide the credentials for each group as an input while you run the script.
 
For sample contents of the HostList.csv file, see Sample-HostList-csv-file.
