ProSafe Managed Switch Email Alerting Email Alerting is an extension of the logging system. The logging system allows you to configure a set of destinations for log messages. This feature adds the email configuration, through which the log message are sent to a configured SMTP server such that an administrator may receive the log in an email account of their choice. This feature is enabled globally. When email alerting is enabled, selected log messages are sent to an SMTP server. Log messages are divided into three groups by severity level: urgent, non-urgent, and never. FOR POSITION ONLY (FPO) Figure 36. Log message severity levels The network administrator can adjust the urgent and non-urgent severity levels. These levels are global and apply to all destination email addresses. Log messages in the urgent group are sent immediately to the SMTP server with each log message in a separate mail. Log messages in the non-urgent group are batched into a single email message and after a configurable delay. Email alerting also provides a configuration option that allows the network administrator to specify the severity level at which SNMP traps are logged. Using this option, the administrator can put traps in the urgent group, the non-urgent group, or the never group for emailing. Traps are not emailed by default. For traps to be emailed, the network administrator has to either increase the severity at which traps are logged, or lower the severity level of log messages that are emailed. The network administrator can configure multiple destination email addresses, and for each email address, specify whether to deliver urgent log messages, non-urgent log messages, or both. There is an exception to the sending of the messages periodically to the SMTP server. When the log buffer is completely full before the expiry of the periodic timer sending of the log messages to the SMTP server does not until the expiry of the timer. When the log buffer is full, a connection is opened immediately with the SMTP server, and all the messages that have not previously been emailed are sent to it. 336 | Chapter 18. Syslog
