Prometheus is using snmp_exporter to monitor the storage system, the information collected from oid is written to label_value, the value queried using PromQL is always 1, is there any way to output the value of label_value as a value?

I am trying to gather counts of BGP prefixes sent to each peer from a Juniper router, using snmp_exporter. There is a SNMP metric for this: jnxBgpM2PrefixOutPrefixes, however this indexes on this do not have the local and remote peer addresses, instead have a index called jnxBgpM2PeerIndex. If i walk jnxBgpM2PeerIndex it gives me the local/remote addresses as indexes and the peer index as value.
