Network data metrics for BHNM


The Network Device Summary Datamart stores aggregated network device data collected from BHNM. These metrics are mapped to the appropriate network device datasets and support monitoring, performance analysis, and capacity planning. The data imported into this datamart is sourced from the CSV files generated by the netreo-site-connector.sh script, as described in Collect network device data from BHNM.

BHNM device overview - Switch (relies on the BYIF metrics)

Metric NameMappingStatisticShort descriptionLong description
Name  entname NA Name of the network deviceNA
HW_Model Hw_modeNAHardware model of the deviceNA
Location Farm_name NALocation or site of the deviceNA
Device_Latency_MS icmp_latency AVG Average ICMP latency of the deviceNA
IF_Count DerivedCNTTotal number of interfaces on the deviceCount of all interfaces of a network device (sub-resources of BYIF metrics) 
IF_BusyDerivedCNTNumber of interfaces now carrying traffic

Count of all interfaces that have either outgoing or incoming traffic. 
Check traffic based on the following Derived: 
BYIF_IN_BIT_RATE_AVG != 0 OR BYIF_OUT_BIT_RATE_AVG != 0 

For each interface, if the earlier condition is met, the count is incremented by 1

WORST_IF_AVG_PCTDerivedAVGHighest average utilization across all interfaces

For each network device, average the following metrics over all interfaces: 

  • BYIF_OUT_ERROR_RATE 
  • BYIF_IN_ERROR_RATE
  • BYIF_OUT_BIT_RATE
  • BYIF_IN_BIT_RATE 

Then takes the greatest value (greatest average).

WORST_IF_MAX_PCTDerivedMAXHighest maximum utilization across all interfaces

For each network device, get the max value of the following metrics over all interfaces:

  • BYIF_OUT_ERROR_RATE 
  • BYIF_IN_ERROR_RATE
  • BYIF_OUT_BIT_RATE
  • BYIF_IN_BIT_RATE 

Then takes the greatest value (greatest max).

IF_ERROR_STATUSDerivedNAIndicates whether any interface reported errors

Gets the max value of  BYIF_OUT_ERROR_RATE and  BYIF_IN_ERROR_RATE over all interfaces and checks if their sum is greater than zero. If yes, the value of the metric is ‘1’, otherwise ‘0’.

(Answers the question, "Was there an error in any of the interfaces?")

CPU_AVG_PCTCPU_UTIL (AVG) AVGAverage CPU utilization over the selected timeframeThe average of all CPU_UTIL data points for the network device over the configured timeframe 
CPU_MAX_PCTCPU_UTIL (MAX) MAXMaximum CPU utilization over the selected timeframe

The maximum of all CPU_UTIL data points for the network device over the configured timeframe 

Memory_AVG_PCTMEM_UTIL (AVG)AVGAverage memory utilization over the selected timeframe

The average of all MEM_UTIL data points for the network device over the configured timeframe 

Memory_MAX_PCTMEM_UTIL (MAX)MAXMaximum memory utilization over the selected timeframe

The maximum of all CPU_UTIL data points for the network device over the configured timeframe
