Built for MSPs

Checkmk

Host-based · Cloud / On-prem · Free trial

Checkmk bridges the gap between open-source server monitoring and commercial platforms — the Raw Edition is genuinely free with no host limits, while auto-discovery and rule-based configuration make it faster to deploy than Zabbix or Nagios for teams with Linux administration skills.

Best for: IT and DevOps teams managing heterogeneous server environments — Windows, Linux, and containers — that want enterprise monitoring depth without per-host subscription costs. The Raw Edition fits budget

Other server monitoring software tools

These tools are part of the server monitoring software category but may not match the for msps filter above. Worth reviewing if the primary options don't fit.

Datadog Infrastructure

Host-based · Cloud · Free trial

Datadog Infrastructure is the dominant cloud-native monitoring platform with 900+ integrations and unified metrics-traces-logs correlation — but per-host pricing that looks simple at $15-23/host/month masks custom metric overages and module sprawl that push real bills 2-4x higher.

Dynatrace

Custom quote · Cloud · Free trial

Dynatrace is the most automated full-stack observability platform available — OneAgent auto-discovers and instruments everything from infrastructure through application code through user experience with AI-powered root cause analysis — but the premium pricing and enterprise sales cycle make it a poor fit for SMBs.

LogicMonitor

Custom quote · Cloud

LogicMonitor is a SaaS-based hybrid monitoring platform with 3,000+ integrations and AI-powered alerting that covers servers, cloud, network, and containers from one console — but the hybrid unit pricing model requires careful cost modeling before commitments.

ManageEngine OpManager

Custom quote · Cloud / On-prem · Free trial

ManageEngine OpManager provides on-premises server and network monitoring with published pricing from ~$245 for 10 devices — a practical mid-market choice for IT teams that want to evaluate costs before talking to sales, with the caveat that add-ons for NetFlow, firewall, and APM push the real bill higher.

Nagios XI

Custom quote · On-prem · Free trial

Nagios XI is the commercial server monitoring platform built on the Nagios Core engine with 4,000+ community plugins — offering perpetual licensing and complete on-premises deployment, but requiring genuine Linux administration skills and manual configuration that modern alternatives have automated.

New Relic

Usage-based pricing · Cloud · Free trial

New Relic provides full-stack observability — infrastructure, APM, logs, browser, and mobile — with a usage-based pricing model that charges per ingested GB rather than per host, making it price-competitive for large server fleets but unpredictable when data volumes spike.

Pandora FMS

Custom quote · Cloud / On-prem · Free trial

Pandora FMS is an on-premises monitoring platform that combines server, network, and application monitoring with a Community Edition that handles up to 100 agents free — a viable alternative for organizations that need self-hosted monitoring without Zabbix's learning curve, though the Enterprise Edition pricing requires sales engagement.

Sematext Cloud

Usage-based pricing · Cloud · Free trial

Sematext Cloud is a lightweight observability platform that combines infrastructure monitoring, log management, and real user monitoring at 50-70% less than Datadog — purpose-built for teams that need unified observability without enterprise platform complexity or cost.

Sensu Go

Custom quote · Cloud / On-prem · Free trial

Sensu Go is an API-driven monitoring pipeline designed for infrastructure-as-code teams that need to treat monitoring as programmable infrastructure rather than a GUI-configured tool — strongest for organizations running multi-cloud and containerized workloads where traditional agent-based monitoring breaks down.

Site24x7

Host-based · Cloud · Free trial

Site24x7 bundles server monitoring with website uptime, APM, network, and cloud monitoring in a single SaaS platform starting at $9/month — delivering breadth that competitors charge 3-5x more for, with the tradeoff of monitor-credit complexity and a cluttered UI.

SolarWinds NPM

Custom quote · On-prem

SolarWinds NPM is primarily a network monitoring platform, but its server monitoring capabilities through node polling and PerfStack correlation make it relevant for teams already running Orion — though organizations needing dedicated server monitoring should evaluate SolarWinds SAM instead.

SolarWinds Server & Application Monitor

Custom quote · On-prem

SolarWinds SAM is the on-premises application and server monitoring workhorse that pairs with Orion NPM to give Windows-centric IT ops teams deep visibility into 1,200+ application templates — but the SQL Server dependency and element-based licensing require careful capacity planning.

VMware Aria Operations

Custom quote · Cloud / On-prem

VMware Aria Operations (formerly vRealize Operations) is the purpose-built monitoring and capacity planning platform for VMware vSphere environments — unmatched for VM right-sizing, capacity forecasting, and vSAN monitoring, but limited outside the VMware ecosystem and complicated by Broadcom's acquisition changes.

Zabbix

Open source · Cloud / On-prem · Free trial

Zabbix is the most capable fully open-source server monitoring platform available — zero licensing cost at any scale, with enterprise features like auto-discovery, distributed monitoring, and template-based configuration that commercial tools charge thousands for — but the learning curve is steep and the UI shows its age.

For MSPs FAQ for server monitoring software

What server monitoring software features do MSPs need?

Multi-tenant dashboards with per-client isolation, PSA integration (ConnectWise, Autotask, Halo), white-label portals, per-technician or per-endpoint pricing with volume discounts, automated alerting with NOC escalation, and reporting that doubles as client deliverables.

How should MSPs evaluate server monitoring software pricing?

Compare per-technician (unlimited endpoints) vs per-endpoint models. For MSPs managing 500+ endpoints with 2-3 technicians, per-technician pricing is almost always cheaper. Factor in PSA integration costs, add-on modules, and minimum commit requirements.

Can MSPs use the same server monitoring software tools as internal IT?

Some tools serve both markets (NinjaOne, Datto), but MSP-specific features like multi-tenancy, white-labeling, and PSA integration are usually only available in MSP-tier plans. Internal IT tools (Intune, SCCM) lack multi-tenant architecture entirely.
