Example

Command line parameters

The script can be executed in command line or from the crontab (see: Manage recurring jobs: license expiration check, log events (cron)) using the following command:

Some parameters are available:

• Number of days before the license expires that will generate an alert → specify a number of days (default = 7)
• Prevent from sending default email → -nomail . This option is useful when a custom script is created to send alerts (see further)
• Force the expiration date for debugging → -expdat=<DD-MMM-YYYY>  where DD = day of the month, MMM = month (3 characters, 1st letter uppercase), YYYY = year

Example (command executed on 21-Jul-2020):

This command, with forced expiration date, will provide the following results:

Custom alert script

A customer script can be created to send alerts for example when a monitoring software is installed.

The script has to be created in /opt/charon/utils folder and named charon_expchk.custom with "execute" permission.

It is invoked for each product and has the following parameters:

• $1 = level that can be (case sensitive): Informational, Minor, MAJOR, CRITICAL, EXPIRED or NEUTRAL
  • Note: NEUTRAL is sent when no alert is detected, used to send counter alert.
• $2 = message starting with ":" followed by the license expiration date, the license number and the product.
  • Example: : 23-Jan-2021. License: 1001687. Product: CHARON-PA9-64-L4
