Centreon vs HWMonitor

Centreon is an IT monitoring platform for infrastructure spanning cloud environments and edge systems. It monitors servers, networks, cloud environments, and applications, with more than 700 connectors for areas including infrastructure, security, databases, middleware, and OT systems. Deployment is available as SaaS or self-hosted software. Integrations include ServiceNow, JIRA, GLPi, EasyVista, Microsoft Teams, Slack, Telegram, PagerDuty, and OpsGenie; stream connectors can send metrics and events to Elastic, Kafka, and Splunk. Access controls include fine-grained permissions, SAMLv2 identity-provider integration, and Active Directory and LDAP synchronization. Centreon uses TLS-encrypted communications and supports secure collection through its monitoring agent or poller. The agent monitors Linux and Windows hosts and streams metrics over encrypted gRPC. The core platform is distributed under the Apache license, with GPLv2 applying to some files. The free plan covers up to 100 hosts; paid plans start at €2.27 per host, and Centreon Cloud has a 7-day trial for up to 125 hosts. Centreon Experience Monitoring offers a separate 30-day trial.

HWMonitor reads PC system-health sensors, including temperatures, voltages, power, current, fan speed, utilization, and clock speeds. It covers CPUs and GPUs, supported LPCIO chips, memory modules with thermal sensors, S.M.A.R.T. storage devices, and batteries. The listed Windows release is version 1.68 for x86/x64, available as an installer or ZIP download, and CPUID lists a separate Windows ARM64 download. Version 1.68 adds PCI Express error counters for AMD and Intel GPUs, NPU and platform metrics, HDD IOPS and average latency, and saved device and sensor tree state. CSV logging is listed as a feature. The free HWMonitor plan monitors PC hardware sensors on Windows x86/x64. HWMonitor PRO adds remote monitoring over TCP/IP, saved monitoring data, and bitmap logging graphs. Its Android app reports device temperatures and battery details, plus CPU clock and utilization and, on supported devices, GPU clock. Android remote connections require local Wi-Fi, and the app can monitor up to 10 Windows PCs or Android devices.
