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:
# /opt/charon/utils/charon_expchk |
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:
# /opt/charon/utils/charon_expchk 15 -nomail -expdat=13-Dec-2018 |
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, CRITITAL, 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:
: 13-Dec-2018. License: 1003415. Product: CHARON-AXP
- Example:
