If you have your ifAlias well standardized you can use metric_relabel_configs to extract data.
metric_relabel_configs: - source_labels: [ifAlias] regex: "(.+) - (.+) - (.+)" replacement: "$1" target_label: port_description - source_labels: [ifAlias] regex: "(.+) - (.+) - (.+)" replacement: "$2" target_label: port_location - source_labels: [ifAlias] regex: "(.+) - (.+) - (.+)" replacement: "$3" target_label: cable_id This will separate out your ifAlias into the component label parts.
