According to the source in prometheus-common/model/labels.go, these are the
only declared magic labels:
const (
// AlertNameLabel is the name of the label containing the an
alert's name.
AlertNameLabel = "alertname"
// ExportedLabelPrefix is the prefix to prepend to the label names
present in
// exported metrics if a label of the same name is added by the
server.
ExportedLabelPrefix = "exported_"
// MetricNameLabel is the label name indicating the metric name of a
// timeseries.
MetricNameLabel = "__name__"
// SchemeLabel is the name of the label that holds the scheme on
which to
// scrape a target.
SchemeLabel = "__scheme__"
// AddressLabel is the name of the label that holds the address of
// a scrape target.
AddressLabel = "__address__"
// MetricsPathLabel is the name of the label that holds the path on
which to
// scrape a target.
MetricsPathLabel = "__metrics_path__"
// ReservedLabelPrefix is a prefix which is not legal in
user-supplied
// label names.
ReservedLabelPrefix = "__"
// MetaLabelPrefix is a prefix for labels that provide meta
information.
// Labels with this prefix are used for intermediate label
processing and
// will not be attached to time series.
MetaLabelPrefix = "__meta_"
// TmpLabelPrefix is a prefix for temporary labels as part of
relabelling.
// Labels with this prefix are used for intermediate label
processing and
// will not be attached to time series. This is reserved for use in
// Prometheus configuration files by users.
TmpLabelPrefix = "__tmp_"
// ParamLabelPrefix is a prefix for labels that provide URL
parameters
// used to scrape a target.
ParamLabelPrefix = "__param_"
// JobLabel is the label name indicating the job from which a
timeseries
// was scraped.
JobLabel = "job"
// InstanceLabel is the label name used for the instance label.
InstanceLabel = "instance"
// BucketLabel is used for the label that defines the upper bound
of a
// bucket of a histogram ("le" -> "less or equal").
BucketLabel = "le"
// QuantileLabel is used for the label that defines the quantile in
a
// summary.
QuantileLabel = "quantile"
)
Hence I don't think you can do what you want in relabeling; you need
separate jobs.
