| The information on this page refers to License Statistics v6.5 or newer, which introduced Reservation reports. If you are using an earlier version of License Statistics, please refer to the documentation for releases prior to v6.5. |
If you use a different license server than one of those currently supported by License Statistics (see Supported license servers), you can customize License Statistics to run with your specific license server. To run License Statistics with your license server, your parser must write an UTF-8 encoded XML file that License Statistics can read and understand. In this way, virtually any licensing system can communicate with the License Statistics graphing engine.
See Adding and editing license servers for information about adding a custom license server to License Statistics.
License Statistics will read your XML file at each update interval. You should generate the XML files on a regular, scheduled basis. You can schedule the XML file generation using Windows scheduler for Windows or crontab for Linux. Note that the custom parser is a realtime parser that contains the current state of the license server. When regenerating the XML, replace (do not append to) the previous XML file.
The specifications for the XML file are as follows:
- CUSTOM_STAT – required
- VENDOR – required
- USAGE – the usage of a single feature
- FEATURE – required; the name of the feature
- VERSION – the version of the feature
- USED_LICENSES – the sum of licenses used by users (including borrowed licenses, but excluding reserved licenses)
- DENIED_LICENSES – the sum of denied licenses
- BORROWED_LICENSES – the sum of licenses borrowed by users
- RESERVED_LICENSES – the sum of remaining reservations
- TOTAL_LICENSES – "UNLIMITED" or numeric value of licenses in the feature
- SHARE – the type of license sharing in use
- EXPIRES – "PERMANENT", or an empty string, or the date on which the feature is set to expire, in "YYYY-MM-dd" format - USER – the usage of the feature for a single user
- USERNAME
- HOSTNAME
- IP – the user's IP address
- USED_LICENSES – the number of licenses used by the user
- DENIED_LICENSES – the number of licenses the user was denied
- BORROW_EXPIRE_TIME – if the used licenses are borrowed, the date when the borrow is due to expire, in "YYYY-MM-DD HH:mm" format
- CHECKOUT_TIME – required; the date on which the user checked out the licenses, in "YYYY-MM-DD HH:mm" format
- RESERVATION - reservation for the feature
- TYPE - reservation type, one of: UNKNOWN, DYNAMIC, USER, USERGROUP, HOST, HOSTGROUP, IP, PROJECT, DISPLAY. Defaults to UNKNOWN
- PATTERN - pattern describing reservation, f.e user name, ip address etc. May include wildcards. Required for type other than UNKNOWN. Defaults to '*' for Unknown
- TOTAL - total number of reservations
- REMAINING - required; number of unused reservations
- SINCE - indicates the beginning of reservation period; in "YYYY-MM-DD HH:mm" format
- EXPIRES_AT - indicates the end of reservation period; in "YYYY-MM-DD HH:mm" format
Important:
- USED_LICENSES and DENIED_LICENSES have to be located in separate USER entries.
- All dates and times must be in the format specified for the variable in the list above.
- Only one VENDOR name can be used.
An example of the content for a custom parser XML file is given below.
