All alerts coming from monitoring scripts and checks scripts are sent using a common alert script that sends emails (via "sendmail") to the recipients list that can be defined using this option.

Do not add blank lines and set one recipient per line

Update/reinstall common alert script
...
- Answer "
yes" if you did not change the original script file and you have updated the Linux Toolkit (read the corresponding release notes) - Do not answer "
yes" if you customized your own alert script. In case you've overwritten the existing alert script, the previous version can be restored from the "/charon/archive" folder
Example:
This script can be customized to send alerts the way you want, adding for example commands to link with your monitoring tool. It is based on an alert code passed as parameter 1.
...

View alerts history
This option will allow you is used to view the alerts history sent via the alert script. Alerts can be viewed in a continuous way or using a text editor.Example - Continuous view:
We can see above:
- A message telling the emulator is started
- A message telling the license (main one) is found and that also displays its expiration date
- The main license dongle has been unplugged and the
aksusbdmonitor reported the alert (immediate). We can see one license (backup one) is still connected - Warning messages are sent for the hardware requirements
- The license dongle was plugged in again. We do not see here any dongle removal alert reported by the emulator itself, this is because by default the emulator checks for dongle presence every 1 hour (deferred)

License expiration alerts from guests
...
Backup licenses (time limited): please take care of the time remaining that will be reported in the license detection alert, if the number of remaining hours is less than 24, you could not receive any alert from the license expiration check that runs everyday at 09:00 AM by default. It is possible to make it run more than once a day in this case.

Alerts simulator
This option allows you to send all the available alerts for testing:
Hardware specs warning message Enabled
Enable or disable hardware specifications warning messages to be sent on Charon boot. Depending on Charon version, wrong messages can be sent. This this option prevents from sending warning alerts in case harwdare specifications warning messages are displayed in the log file.
| Div | ||
|---|---|---|
| ||
Immediate alert on dongle removal Enabled
Enable or disable immediate alert on dongle removal. These alerts are monitored by the aksusbd log monitoring which is totally independent from the Charon virtual machine log files monitoring.
Since Charon version V4.9, the license communications are checked more often than they were in previous versions.
This option, if disabled, prevents from sending too many alerts in case of dongle removal and re-connection but be aware that if no Charon virtual machine is running, the removal and re-connection will not generate any alert.
Reduce WARN msgs on dongle removal
This option is valid for Charon-AXP and Charon-VAX V4.9 and above.
If enabled, it will prevent from sending too many alerts on dongle removal thus the following messages will not generate an alert:
:0000024D:licenseman(1830): Unable to log in to the key "XXXXXXXX", feature X.:0000024D:licenseman(1830): HASP runtime (7): Sentinel protection key not available.:0000024D:licenseman(1830): Failed to login at the Sentinel HASP key: "XXXXXXXX".
