Summary of Environment

The NOC tooling software stack is built from some off the shelf components, with some custom automation tooling and some bespoke tools, all of which sit on RHEL 6.7.

  • CMDB+ - THE NMS Configuration Management Database - a bespoke database system with hooks into most of the other tools.

  • NNMi (Network Node Manager) the MicroFocus Network Management System - relies heavily on SNMP (v2 and v3)

  • NA (Network automation) the MicroFocus Network Configuration Management tool - regularly takes snapshots of network device configs

  • Synapse - bespoke syslog and SNMP trap receiver, with custom parsing and correlation rules built in.

  • OML (Operations Manager for Linux) - an event aggregator and correlator which receives events from NNMi and Synapse, and requests SM9 tickets where necessary.

  • TACACS+ - an Authentication, Authorization and Accounting protocol - we use the open source tac_plus

  • Most of these systems rely on Database back ends, so DBMS knowledge would be useful.
