Reasons buyers look elsewhere
- Steep learning curve for new users — teams without dedicated monitoring staff often switch to Nagios or Zabbix for faster onboarding
- Pricing scales with monitored hosts; organizations managing 500+ servers frequently layer in Datadog or New Relic for cost-effective cloud monitoring
- Limited native cloud integrations — AWS and Azure-heavy shops add CloudWatch or Azure Monitor for native service connections
- Dashboard customization is limited compared to competitors like Grafana or Prometheus, which offer more flexible visualization options
- Pricing scales poorly for large deployments — organizations managing 500+ servers often switch to open-source alternatives or Datadog for better cost efficiency
- Missing native integrations with ServiceNow, Splunk, and other enterprise tools requires custom API work or third-party connectors
