Alerts management

Description

This option will allow you to change alert management settings as shown below:

Settings

Select alert mail mode (HTML/TEXT)

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:

TEXT mail example:

Update alert 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 to the recipient list that can be customized using this option

It is edited using ‘vi’ editor or if installed, the ‘nano’ editor, or, if possible, the ‘gedit’ graphical editor (Windows notepad like) or ‘emacs’.

Notes:

• No comments allowed
• No blank lines
• One recipient per line

Create/update alert mail footer

Used to add comments at the end of the mail. 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

Alert are by default sent via email (sendmail) and also warns the connected user via a wall message.

This option enables or disables these wall messages.

Update/reinstall common alert script

All alerts coming from monitoring scripts and checks scripts are sent using a common alert script.

If this script does not exist, it is initialized by copying an example provided.

If it exists and is different from the original one, you are invited to reinitialize it from the default one:

• use this if you did not change the original script file and you updated the Linux Utilites kit
• do not use this if you customized your own alert script

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. All other parameters are information used to send alerts by default with a ‘wall ‘ command and an email sent to the alert mail recipients list described above. The script uses templates in order to send emails and wall messages (templates/*.mail and templates/*.wall files)

It is edited using ‘vi’ editor or, if possible, the ‘gedit’ graphical editor (Windows notepad like).

Parameter1 can be the following:

Select guests log alert level

Select the alert level to send alerts when events are found in the guest log file:

Level	Information	Warning	Error
0
1
2
3

Requires the charon_logevent entry activated in the crontab file => menu option 5 - Manage recursive jobs: license expiration check, log events (cron)

This does not affect guest startup alerts. You will receive alerts when a guest starts whatever the level is
