I'm looking for a way to deal with a situation where we end up with null characters trailing some label values: `count({ifDescr=~".*\x00"}) != 0`.
The source of the problem seems to be with `ifDescr` returned as a `Hex-String` instead of what the MIB says should be a `DisplayString`... for __some__ servers. # Good, 99% of servers: $ snmpget -v 2c -c $creds 172.21.34.10 1.3.6.1.2.1.2.2.1.2.1 iso.3.6.1.2.1.2.2.1.2.1 = STRING: "eth0" # Bad, Cisco CVP tsk tsk tsk... $ snmpget -v 2c -c $creds 172.20.220.88 1.3.6.1.2.1.2.2.1.2.1 iso.3.6.1.2.1.2.2.1.2.1 = Hex-STRING: 53 6F 66 74 77 61 72 65 20 4C 6F 6F 70 62 61 63 6B 20 49 6E 74 65 72 66 61 63 65 20 31 00 I'm currently planning on using `metric_relabel_configs` to cleanup the trailing nulls on these and other similar situations I uncovered. Is there better way than mopping up like that? Perhaps snmp-exporter can deal with these and convert somehow? I'm not familiar enough with it to figure out if it can or not. -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
