More simply, using the @views macro on a block of code converts all string slices into substrings. For example: julia> str = "long

escalation schedule, recipient, media type • notifications can be made meaningful and helpful using macro variables • automatic actions include remote commands Real-time graphing • monitored items are immediately agent 2 on Windows Macros Ability to mask macro content in the frontend Macro value field now has Secret text mode. If enabled, it masks the content of a macro with asterisks to protect sensitive information User macros can now be defined for host prototypes and LLD macros can be used in the macro value fields (the LLD macro will be resolved when a host is created from the prototype). User macros supported in
