Introduction

An OpenNSA infrastructure (and any NSI based infrastructure) is highly distributed and difficult to monitor and manage. At the moment every OpenNSA node has its own set of logfiles and of course the standardized NSI SOAP/REST  calls that can be used to monitor the state of the node. However, watching the unstructured logmessages in the logfiles and triggering the minimalistic NSI calls can be a lot of work.

Here is a short list of possible strategies to monitor openNSA nodes that has fewer shortcomings then the current way of working:

  1. Using centralized  and structured logfiles, together with some analysis/search interface
  2. Provide openNSA with SNMP calls and monitor them with an SNMP based management station
  3. Send events from openNSA nodes using some Message Queue infrastructure
  4. add REST monitoring calls to openNSA
