View Mail Events

 

The 'Mail Events' area contains logs of all actions taken by Mail Gateway. A 'Mail Event' is triggered whenever a mail is filtered for spam or an action is taken for a email with attachment that contains virus or malware.

 

To view a log of Mail Events

• Click on the results displayed under the 'Infections' or 'Spam' column in the Summary screen.

Column Description

• Date - Indicates the date of the event.

• Sender - Displays the name of the email sender.

• Subject - Displays the subject line of the email.

• From - Displays the IP address of the sender.

• Location - Indicates the location where the application detected with a threat is stored.

• Type - Displays whether mail contains virus or spam.

• Malware Name - Name of the malware event that has been detected.

• Spam - Indicates the size of spam mail.

• Action - Indicates action taken against the malware.

• Status - Gives the status of the action taken. It can be either 'Success' or 'Fail'.

Comodo Mail Gateway Log Viewer Module

• Click 'More ...' to load the full Comodo Mail Gateway Log Viewer module.

OR

• Click 'View Logs' in the Applications menu in the panel to load the full Log Viewer module.

This window contains a full history of logged events in two categories: Logs per Module and Other Logs.

 

It also allows you to build custom log files based on specific filters and to export log files for archiving or troubleshooting purposes.

 

The Log Viewer Module is divided into three sections. The top panel displays a set of handy, predefined time Filters. The left panel the types of Logs. The right hand side panel displays the actual events that were logged for the time period you selected in the top panel and the type of log selected in the left panel (or the events that correspond to the filtering criteria you selected).

 

The Logs per Module option contains the logged events of Antivirus modules and Other Logs options contains logged events of the following:

• Alerts Displayed: Displays the list of various alerts that were displayed to the user, the response given by the user to those alerts and other related details of the alert.

• Tasks Launched: Displays the various Antivirus tasks such as updates and scans that have taken place. This area will contain a log of all on demand and scheduled AV scans and the result of that scan.

• Configuration Changes: Displays a log of all configuration changes made by the user in the CAVL application.

 Filtering Log Files

Comodo Antivirus and Mail Gateway allows you to create custom views of all logged events according to user defined criteria.

 

 Preset Time Filters:

 

Clicking on any of the preset filters in the top panel alters the display in the right hand panel in the following ways:

• Today - Displays all logged events for today.

• Current Week - Displays all logged events during the current week. (The current week is calculated from Monday to Sunday that holds the current date.)

• Current Month - Displays all logged events during the month that holds the current date.

• Entire Period - Displays every event logged since Comodo Antivirus for Linux was installed. (If you have cleared the log history since installation, this option shows all logs created since that clearance.)

The example below shows an example display when the Mail Events for 'Today' are displayed.

Note: The type of events logged by the Antivirus modules of CAVL differ from each other. This means that the information and the columns displayed in the right hand side panel change depending on which type of log you have selected in the top and left hand side panel. For more details on the data shown in the columns, see View Antivirus Events.

User Defined Filters:

 

Having chosen a preset time filter from the top panel, you can further refine the displayed events according to specific filters. The type of filters available for Mail logs differ to those available for Antivirus logs. The table below provides a summary of available filters and their meanings:

Available Filters - Logs per Module
Antivirus Filter	Mail Filters

Location - Displays only the events logged from a specific location	Subject - Displays only the events according to the subject in the mail
Malware Name - Displays only the events logged corresponding to a specific malware	From IP - Displays only the events with a specific From IP address
Status - Displays the events according to the status after the action taken. It can be either 'Success' or 'Fail'	Location - Displays only the events logged from a specific location
	Type - Displays only the events logged corresponding to specific type of mailware in the mail
	Malware Name - Displays only the events logged corresponding to a specific malware
	Spam - Displays only the events logged corresponding to a specific spam mail
	Action - Displays events according to the response (or action taken) by CAVL
	Status - Displays the events according to the status after the action taken. It can be either 'Success' or 'Fail'

Creating Custom Filters

Custom Filters can be created through the Advanced Filter Interface. You can open the Advanced Filter interface either by using the View option in the menu bar or using the context sensitive menu.

• Click View > Advanced Filter to open the 'Advanced Filter' configuration area.

Or

• Right click on any event and select 'Advanced Filter' option to open the corresponding configuration area.

The 'Advanced Filter' configuration area is displayed in the top half of the interface whilst the lower half displays the Events, Alerts, Tasks or Configuration Changes that the user has selected from the upper left pane. If you wish to view and filter event logs for other modules then simply click log name in the tree on the upper left hand pane.

 

The Advanced Log filter displays different fields and options depending on the log type chosen from the left hand pane (Antivirus, Mail).

 

This section will deal with Advanced Event Filters related to 'Mail Events' and will also cover the custom filtering that can be applied to the 'Other Logs' (namely 'Alerts Displayed', 'Tasks' Launched' and 'Configuration Changes'). The Antivirus Advanced Event Filters is dealt in the respective section.
