Serviceability message routing can also be specified by the contents of certain environment variables. If environment variables are used, the routes they specify will override any conflicting routings specified by a routing file.
The routings are specified (on the basis of severity level) by putting the desired routing instructions in the following environment variables:
· SVC_FATAL
· SVC_ERROR
· SVC_WARNING
· SVC_NOTICE
· SVC_NOTICE_VERBOSE
Each variable should contain a single string in the following format:
out_form:dest;[out_form:dest ...] [GOESTO:{sev | comp}]
where out_form and dest have the same meanings and form as described in Using a Routing File. Multiple routings can be specified with semicolon-separated additional strings specifying the additional routes, as shown.
