We have ASR1006 monitor by observium but its monitoring basic details just like ordinary router. It would be good if it monitor and detect all module in router and give details about individual modules. something like following

SNMP OID to Monitor RP/ESP/SIP CPU Utilization

ASR1K#show platform software status control-processor brief | section Load
Load Average
Slot Status 1-Min 5-Min 15-Min
RP0 Healthy 0.75 0.47 0.41
ESP0 Healthy 0.00 0.00 0.00
SIP0 Healthy 0.00 0.00 0.00
It corresponds to:
1.3.6.1.4.1.9.9.109.1.1.1.1.24.2 = Gauge32: 75 – 1 min RP0
1.3.6.1.4.1.9.9.109.1.1.1.1.24.3 = Gauge32: 0 – 1 min ESP0
1.3.6.1.4.1.9.9.109.1.1.1.1.24.4 = Gauge32: 0 – 1 min SIP0
1.3.6.1.4.1.9.9.109.1.1.1.1.25.2 = Gauge32: 47 – 5 min RP0
