License expiration check
Description
Checks the license expiration interactively. This check is also performed automatically, by default everyday at 09:00 AM, and starts sending alerts 15 days before expiration. See Manage recursive jobs: license expiration check, log events (cron) for more and customization.
Alert levels are defined as follows:
Days before expiration (date limited license) | Hours before expiration (time limited license) | Alert Level |
|---|---|---|
More than 7 | More than 72 hours | INFORMATIONAL |
Between 4 and 7 | Between 49 and 72 hours | MINOR |
Between 2 and 3 | Between 25 and 48 hours | MAJOR |
Less than 2 | Between 0 and 24 hours | CRITICAL |
< 0 | 0 hours and 0 minutes | EXPIRED |
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:

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
