Benefits of adding Field Resolvers in Logging Profile elements
Field Resolvers convert values in incoming syslog fields to different values in SMC logs.
There are two types of Fields Resolvers: multi-value field resolvers and date field resolvers.
Multi-valued field resolvers
You can use multi-valued field resolvers in the following case:
To convert one value to several log fields — In some cases, a single value can have several corresponding log fields in SMC logs. A Field Resolver can parse a single value into multiple SMC log fields. For example, SMC components set an Action, a Situation, and an Event for traffic filtering decisions. If the external component notifies a “permitted” action, the Field Resolver can set the corresponding SMC log values for all 3 log fields.
Date field resolvers
You can use date field resolvers in the following case:
Converting time stamps — Different external devices use different date and time formats. A Field Resolver for each different incoming format maps the times and dates correctly to the SMC log format. The date and time syntax in Field Resolvers follows the Java standard.
