Monitoring Citrix NetScaler LB

The eG Enterprise-developed specialized NetScaler LB monitoring model uses the NetScaler's SNMP MIB to track the NetScaler availability and performance 24x7, warns administrators of probable issues in the functioning of NetScaler, and thus wards off potential performance bottlenecks.

Each layer of this hierarchical layer model is mapped to tests that periodically execute on the NetScaler appliance to evaluate its performance. These tests use the snmpport and snmpcommunity string configurations to connect to the SNMP MIB of the NetScaler appliance, and extract a wide range of performance statistics from the MIB. The sections to come will discuss the tests associated with the each of the layers of the NetScaler monitoring model.
