Overall Satisfaction with Nagios
Device availability (Uptime/Downtime) both real time and overtime, SNMP monitoring (CPU utilization, memory, temperature, fan status, disk capacity, etc.), latency tests.
- SNMP Monitoring
- Intuitive and simple-to-use interface
- Great cost-value balance
- Fault tolerance (redundancy)
- Not so easy to restore information
- Much better network device performance metrics allowing to troubleshoot and do before/after changes comparisons
- Has helped us to integrate with our Service Management tool (through other 3rd party tools)
- Important part of our overall network health dashboard providing granular details at the device level (not end-to-end performance)
- Cost is very convenient
The cost is considerably better. Others are probably more complete and even overkilled if all you're looking for is simple SNMP alerting and reporting. If you're looking for integrated analytics or more complex reporting/alerting, there might be better options. Nagios also provides basic NetFlow monitoring in a separate module (also purchased separately) but I don't believe it's all that intuitive and might require additional efforts to set it up compared to other NetFlow tools.
I have hardly involved Nagios since platform is stable for support but the one time that I did they were very responsive. I would probably suggest faster introduction of new features. Compared to other companies that have adopted agile methodologies for development, I believe that Nagios still has some room for improvement.
