For Small Business FAQ for infrastructure monitoring tools
What infrastructure monitoring works best for small businesses?
+
PRTG for on-premises with auto-discovery (free for 100 sensors). Site24x7 for cloud-managed monitoring (from $9/month). Checkmk Raw for self-hosted with the most comprehensive free feature set. Choose based on whether you want cloud-managed or self-hosted.
How much infrastructure monitoring does a small business need?
+
At minimum: uptime monitoring for critical services, disk space alerts, CPU/memory thresholds on servers, and WAN link health. 5-10 metrics per device is sufficient. Don't replicate enterprise monitoring complexity at small business scale.
Can small businesses use Datadog or New Relic?
+
Datadog and New Relic have free tiers but their value is in application-level observability — overkill for small businesses monitoring basic infrastructure. PRTG or Site24x7 provide better infrastructure focus at lower complexity.
