It can also send alerts in case of Charon emulator service state change, if the emulator log file is greater than a specified value and , if the virtual machine (emulator) configuration file has been updated and if the emulator executable file is not present (placed in quarantine by an antivirus software for example).

Alerts can either be an entry added in the Windows Application Events log file (source = CharonLogMonSVC), an email or a .BAT or .PS1 custom script. A mechanism can be set in place to stop sending alerts in case too many alerts are sent during a specified interval.

4 - If needed, you can use the Email settings tab to specify who you want to send emails to and from who. If the sender account needs a password, you'll need to click the "Save" button (does not work with PowerShell 4.0, 5.1 only). It is recommended to use the "Test email alert" button to ensure emails are correctly sent. If the test email is not received, please check the service log from the "Service log" tab.

Notes:

  • A double click on a virtual machine name opens the latest log file
  • A double click on the "Notes" box for a virtual machine opens the "Edit notes" option
  • A circle icon in the details box means the log file is using the log rotation mechanism (highly recommended). Mouse hovering on this icon shows the max file size and rotation period if defined.
  • Other warning icons can be displayed if:
    • The log counters are enabled or
    • The log file size is greater than the limit specified or
    • The log method is set to overwrite (not recommended) or
    • The configuration file has been updated after the emulator was started (an emulator restart is required for the changes to be taken into account)
  • If alerts have been suspended, either manually or due to the limit reached, resuming sending alerts must be done manually
