Cacti
- +Free, stable and extremely light on resources
- +Long-established SNMP graphing with a large body of community templates
- +Runs happily on modest hardware in small or isolated environments
- −Graphing-first: alerting requires plugins and is not a core strength
- −Interface and workflow are dated, and development pace is slow
Best for Small or isolated networks needing long-term interface graphing at no cost
Watch out Treat this as a graphing tool rather than a monitoring and alerting platform
ManageEngine OpManager
- +Considerably cheaper than the enterprise incumbents for comparable coverage
- +Quick to deploy with sensible defaults and good auto-discovery
- +Integrates with the wider ManageEngine estate including Log360
- −Device-count licensing still applies, and add-ons accumulate
- −Depth of analysis trails the specialist platforms at the top of this table
Best for SMB and mid-market teams wanting commercial support without enterprise pricing
Watch out Check which capabilities are core and which are separately licensed add-ons
