Monitoring the Cisco Nexus Switch

eG Enterprise has developed a dedicated Cisco Nexus Switch monitoring model which periodically checks the data traffic to and from each network interface of the switch, the temperature and voltage of each module of the switch, the resource utilization etc, so that abnormalities can be detected before any irreparable damage occurs.

Figure 3 : The layer model of the Cisco Nexus Switch

Every layer of Figure 1 is mapped to a variety of tests which connect to the SNMP MIB of the target Cisco Nexus Switch to collect critical statistics pertaining to its performance. The metrics reported by these tests enable administrators to answer the following questions:

  • Was there CPU resource contention during the last minute or during the last 5 minutes?
  • What is the current state of each fan sensor and the speed of each fan?
  • How well the memory of each memory module is utilized?
  • What is the current state of each sensor of the power supply units?
  • What is the current state of each voltage sensor available in the modules of the target Cisco Nexus Switch?
  • What is the size of the RAM and NVRAM in the target Cisco Nexus Switch?
  • Is the NVRAM utilized adequately or if additional resources need to be added to the NVRAM?
  • What is the current operational status of each fan?
  • Are all the network interfaces of the target Cisco Nexus Switch available?
  • Which network interface is transmitting/receiving the maximum amount of data per second?
  • Is any network interface connected to the target Cisco Nexus Switch error-prone?
