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.
