Hi everyone,
I'm trying to setup the snmp-exporter to poll a Checkpoint Maestro
appliance for system stats. I'm starting small, hitting a single OID,
asgCoreIndex OID which returns a string index with the name of each cpu
core. I can do a walk on this OID with snmpwalk and it returns the
following:
snmpwalk -On -v3 -u <redacted> -l authPriv -a SHA -A <redacted> -x AES -X
<redacted> 1.2.3.4 asgCoreIndex
.1.3.6.1.4.1.2620.1.48.29.1.1.1.0 = STRING: Blade ID

.1.3.6.1.4.1.2620.1.48.29.1.1.3.0 = STRING: cpu1
.1.3.6.1.4.1.2620.1.48.29.1.1.4.0 = STRING: cpu2
.1.3.6.1.4.1.2620.1.48.29.1.1.5.0 = STRING: cpu3
.1.3.6.1.4.1.2620.1.48.29.1.1.6.0 = STRING: cpu4
.1.3.6.1.4.1.2620.1.48.29.1.1.7.0 = STRING: cpu5
.1.3.6.1.4.1.2620.1.48.29.1.1.8.0 = STRING: cpu6
.1.3.6.1.4.1.2620.1.48.29.1.1.9.0 = STRING: cpu7
.1.3.6.1.4.1.2620.1.48.29.1.1.10.0 = STRING: cpu8
.1.3.6.1.4.1.2620.1.48.29.1.1.11.0 = STRING: cpu9
.1.3.6.1.4.1.2620.1.48.29.1.1.12.0 = STRING: cpu10
.1.3.6.1.4.1.2620.1.48.29.1.1.13.0 = STRING: cpu11
.1.3.6.1.4.1.2620.1.48.29.1.1.14.0 = STRING: cpu12
.1.3.6.1.4.1.2620.1.48.29.1.1.15.0 = STRING: cpu13
.1.3.6.1.4.1.2620.1.48.29.1.1.16.0 = STRING: cpu14
.1.3.6.1.4.1.2620.1.48.29.1.1.17.0 = STRING: cpu15
.1.3.6.1.4.1.2620.1.48.29.1.1.18.0 = STRING: cpu16
.1.3.6.1.4.1.2620.1.48.29.1.1.19.0 = STRING: cpu17
.1.3.6.1.4.1.2620.1.48.29.1.1.20.0 = STRING: cpu18
.1.3.6.1.4.1.2620.1.48.29.1.1.21.0 = STRING: cpu19
Hitting the same OID with snmp-exporter shows what I assume are
non-printable characters in the label for asgCoreIndex:
# HELP asgCoreIndex - 1.3.6.1.4.1.2620.1.48.29.1.1

I'm a newbie when it comes to prometheus - any ideas why I'm not getting
the expected response?
Thanks,
Ben.
