Introduction

Novell eDirectory centrally manages access to resources on multiple servers and computers within a given network.

In simplest terms, eDirectory is a hierarchical, object oriented database that represents all the assets in an organisation in a logical tree. Assets can include people, positions, servers, workstations, applications, printers, services, groups, etc.

Inconsistencies in the performance of this central resource-repository could put critical resources out of a normal user's reach. Continued disturbances will hence severely affect organizational productivity. The need therefore is for a monitoring solution that can perform 24 x 7 monitoring of eDirectory and informs administrators of issues, well before any visible damage occurs.

The eG Enterprise with its proactive problem alerting capability is ideal for this purpose. The eG agent serves as a data collector that periodically extracts critical performance statistics from the eDirectory server. The suite then compares these values with manually/automatically set performance baselines, and thus instantaneously detects probable deviations - details pertaining to the probable issues are then quickly provided to administrators, who initiate the corrective measures, without any delay.

The metrics so extracted by the eG agent enables the administrators to find accurate answers to the following performance queries:

Cache Monitoring
  • Are the block and entry caches of the eDirectory server sufficiently sized?
  • Are cache hits optimal?
  • Are there too many direct disk accesses?
Access Monitoring
  • What are the number and type of requests that are handled by the eDirectory server?
  • Is the error rate very high?
  • Are too many requests chained?
  • Is the load on the server manageable?
