I have been looking for a multi-purpose network monitoring tool for use at several network customer location and came across a light-weight app called SpiceWorks. Its open source and has a number of nice features. Here is a list of some of the most useful ones

  • Schedulable network scans based on domain name or subnet
  • Asset classification based on collected data
  • Software inventory (including MS patches)
  • Basic service/system alerts & monitoring
  • User knowledge base portal w/integrated ticketing system
  • Warranty lookup for monitored assets
  • Antivirus tracking (no AV, outdated defs, versions, etc) for a number of popular packages
