Configuring Event Generations
Configuring events customizes the prerequisites of an event.
Perform the following steps to configure the settings for generating events:
Custom Syslog Events
The Custom Syslog Event creates syslog message events based on rule conditions. To end all similar active events, you must update the configuration as per the recommended action provided in the EOS System Message Guide.
An EOS System Message Guide is published with every EOS release. In the guide, you can find all the common system messages generated by devices, including the syslog facility, mnemonic, severity, and log message format. To download the guide, click https://www.arista.com/en/support/software-download and look for SysMsgGuide under EOS release Docs.
Perform the following steps to create a rule for generating syslog events:
Configuring Single Instance Events
CVP creates a single instance event whenever either the specified syslog ID matches with the device syslog ID or the specified syslog message matches with the device syslog message. See Figure 12.
Provide the following information in specified fields to configure a single instance event:
- Syslog ID - Provide facility, severity, and mnemonic of a syslog with
regular expressions in the following fields:
- Facility field - Type the facility of syslog in either simple string or regular expression.
- All severities field - Select the severity of the device.Note: If no severity is selected, CVP considers all available severities.
- Mnemonic field - CVP creates a single instance event when the log message specified in this field matches with a device syslog message.
- Log Message field - The log message to match against the device syslog
message.Note: You must mandatorily configure either a syslog ID or a log message.
- Mute Period field - CVP does not create another similar event using this
rule on a given device until the time period specified in this field expires for
the ongoing event. Note: This prevents a large number of events generated for the same device within a short period of time due to a repetitive syslog message.
- Event Title field - Type the event title.
- Severity From Syslog checkbox - Select the checkbox if you prefer CVP to
select the severity of the generated event to be derived from the syslog message
severity.Note: CVP uses the following syslog message severities to event severities:
- [0, 1, 2] - Critical event
- [3] - Error event
- [4] - Warning event
- [5,6,7,...] - Info event
- Severity dropdown menu - Select the preferred severity of the generated event. Severity is configurable only when Severity From Syslog checkbox is not selected.
- Event Description field - Provide the event description.
- Ignore subsequent rules for selected devices checkbox - Select the checkbox to suppress generating events for a specific syslog or override upcoming configurations.
- Move Up / Move Down buttons - Use this button to manage the sequence of configured syslog event rules.
- Delete button - Click to delete the corresponding rule.
Configuring Time Period Events

Provide the following information in specified fields to configure a time period event:
- Start Log Message field - CVP starts a time period event when the start
log message specified in this field matches with a device syslog
message.Note: The start log message must be a string without special characters.
- End Log Message field - CVP ends a time period event when the end log
message specified in this field matches with a device syslog message.Note: The end log message must be a string without special characters.
- Parameter field - Type the variable that must be configured in log
messages specified in the Start Log Message and End Log Message fields.
- Value field - Type a variable for the specified parameter in either a simple string or a regular expression.
- Add Value - Click to add another variable for the specified parameter.

In this case, the specified log messages matches with Ethernet1 and Ethernet2 values for either starting or ending an event.

In this case, the specified log messages matches with all ethernet values like Ethernet1, Ethernet1/2, Ethernet1/3, and so on for either starting or ending an event.
- Raise Time field - After a start rule matches, the starting of an event
is delayed for the duration specified in this field. Note: If the end event log message arrives before this delay elapses, the event is not generated. This option is useful in situations where you wish to generate an event only when a syslog condition has persisted for at least some set period of time.
- Clear Time field - After an end rule matches, the ending of the ongoing
event is delayed for the duration specified in this field. Note: If the start event log message arrives before this delay elapses, the event is not ended and will continue as an active event. This option is useful in situations where you wish to generate a long single event which may encompass several start/end conditions being met during a set period of time.
- Event Title field - Type the event title.
- Severity From Syslog checkbox - Select the checkbox if you prefer CVP to
select the severity of the generated event to be derived from the syslog message
severity.Note: CVP uses the following syslog message severities to event severities:
- [0, 1, 2] - Critical event
- [3] - Error event
- [4] - Warning event
- [5,6,7,...] - Info event
- Severity dropdown menu - Select the preferred severity of the generated event. Severity is configurable only when Severity From Syslog checkbox is not selected.
- Event Description field - Provide the event description.
- Ignore subsequent rules for selected devices checkbox - Select the checkbox to suppress generating events for a specific syslog or override upcoming configurations.
- Move Up / Move Down buttons - Use this button to manage the sequence of configured syslog event rules.
- Delete button - Click to delete the corresponding rule.
Managing Events
Disabling All Events of the Selected Type
Perform the following steps to disable all events of the selected type:
Disabling All Events of the Selected Type with Exception
Acknowledging Events
Acknowledging an event confirms that you are aware of the corresponding event and its consequences. By default, acknowledged events are hidden and do not send alerts.
Configuring Notifications
The event alerting system sends notifications for CVP events as they alert operating platforms that you have set up. Once you have customized the topology view for your network, provide the required information to configure the monitoring of notifications.
Perform the following steps to configure event alerts:
Configuring Status
The Status section configures monitoring the health of notification system.
Configuring Platforms
The Platforms section specifies what platforms will receive notifications.
Configuring Receivers
The Receivers section configures a receiver for each preferred team to send notifications and link receivers to notification platforms.
Perform the following steps to add new receivers:Configuring Rules
The Rules section customizes notifications that are sent to receivers.
Perform the following steps to add a new rule:
