Understanding the ESI Syslog Parser
The ESI syslog parser adds a UNIX-style regular expression engine for parsing relevant fields in messages from
third-party appliances such as anti-virus gateways, content filters, and intrusion detection systems.
The user creates a list of rules that identify the type of message, the username to which this message pertains, and
the action to be taken when there is a match on the condition.
ESI Parser Domains
The ESI servers are configured into ESI parser domains (see Figure 122) to which the rules will be applied. This
condition ensures that only messages coming from configured ESI parser domains are accepted, and reduces the
number of rules that must be examined before a match is detected (“Syslog Parser Rules” on page573).
messages.When a syslog message is received, it is checked against the list of defined ESI servers. If a server match
is found, the message is then tested against the list of predefined rules.
