Alerts are by default sent in HTML format. With some mail clients, HTML mails are not correctly displayed or even rejected. This option is used to switch between HTML format and pure TEXT format.
HTML mail example:
| Div | ||
|---|---|---|

TEXT mail example:
Mail recipients list
All alerts coming from monitoring scripts and checks scripts are sent using a common alert script which by default sends a "wall" message to all connected users and an email (via "sendmail") to the recipients list that can be defined using this option.
...
HTML tags like new line, font and bold can be added within the file. In case the format is switched to TEXT, these tags will be automatically removed from the text mail.
Example:
Enable/disable wall alert messages
...
- 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.
...
The table below lists all available values for parameter 1 in case you plan to customize the scripts and send alerts by your own (monitoring software lines of commands, snmptrap, etc...)
Parameter 1 can be the following:
Parameter 1 | Severity | Description |
| ABORTED | CRITICAL | Guest has stopped without user or service request |
AKSUSBFAIL | CRITICAL | If the dongle is detected as removed whereas it is disconnected, the askusb daemons are restarted. If the restart fails after 15 tries, this message is sent |
BOOTDUPL | WARNING | Tried to start a guest that is already running or a guest is found more than once in the guests list |
BOOTNOTFND | CRITICAL | The file containing the guests to start is empty or not found |
EMULSTART | INFORMATIONAL | Emulator has been started |
EXPCHK | CRITICAL, MAJOR, MINOR, INFORMATION | The license is about to expire |
FOUND | INFORMATIONAL | License dongle found at startup |
HASPWARN | CRITICAL | Warning messages found in the license, guests cannot start |
| IFCFGADDR | CRITICAL | The network interface defined in the configuration has already an assigned IP address, cannot be used for guest |
| IFCFGCRIT | CRITICAL | One parameter in the ifcfg-ethN file is not configured correctly (mandatory value) |
| IFCFGUNKN | CRITICAL | The interface name defined in the configuration file is not valid (not found with 'ifconfig <eth>' command) |
| IFCFGWARN | WARNING | One parameter in the ifcfg-ethN file is not configured correctly (recommended value) |
INVALID | CRITICAL | Invalid configuration on dongle to start the guest |
NOTFOUND | CRITICAL | The guests have not been able to start at boot due to dongle disconnected |
REMOVED | CRITICAL | Dongle has been removed: the guest sees the dongle as disconnected and will stop after the defined interval if the dongle is not replaced |
REMOVRESET | ERROR | Dongle seen as removed whereas not disconnected (aksusb driver failure). In this case the USB is reset and drivers are restarted ( |
STOPPED | CRITICAL | Guest has been stopped, reasons explained in parameters 4, 5 and 6 |
| STOPPEDREQ | INFORMATIONAL | Guest has been stopped, requested by user or shutdown |
| TESTMAIL | INFORMATIONAL | Used to test email mode when setting HTML or pure TEXT |
TOEXIT | CRITICAL | The guest is about to exit, reasons explained in parameters 4 and 5 |

This option will allow you 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 is found and that also displays its expiration date
- The license dongle has been unplugged and the
aksusbdmonitor reported the alert (immediate) - 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)
