Description: IBM MIB for the Ethernet Network Dispatcher providing load balancing server farm configuration and traffic distribution statistics.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is IBM-ENETDISPATCHER-MIB?

IBM-ENETDISPATCHER-MIB is an IBM module for the Network Dispatcher component of IBM's load-balancing software (later part of WebSphere Edge Server), managing configuration and traffic-distribution statistics for a load-balanced server farm/cluster. It exposes cluster configuration counts, general packet counters, and per-cluster forwarding statistics including discarded and errored packets, along with dedicated trap objects. This is used to monitor the software service health of the load-balancing dispatcher itself, since rising discard or error counts on a cluster reveal load-balancing decisions failing or backend server farm problems, while packet-forwarded-versus-handled-locally counters show how traffic is actually being distributed. No standards-based MIB dependency is stated; it is an IBM-proprietary module predating later IETF server load-balancing MIB efforts. It is deployed on IBM Network Dispatcher load-balancing servers/appliances front-ending web or application server farms. Engineers can download the IBM-ENETDISPATCHER-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in IBM-ENETDISPATCHER-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

  • IBM Network Dispatcher load-balancing servers/appliances

Monitoring Examples

An administrator polls esClstrDscrdPkts and esClstrErrPkts per cluster to detect packets being discarded or erroring during load-balancing decisions, and esClstrForPkts versus esClstrLocalPkts to see how traffic is split between remotely forwarded and locally handled packets. A spike in esForErrPkts or esClstrDscrdPkts on a given cluster would indicate a backend server farm health problem or a misconfigured forwarding rule.

What Can Be Monitored

  • total packets processed
  • packets discarded per cluster
  • packets in error per cluster
  • packets forwarded vs. handled locally per cluster
  • number of clusters configured
