FIM vs Paessler PRTG Network Monitor

FIM is free, open-source software for monitoring file systems on premises. It watches files in the background, keeps historical information, emits events when changes occur, creates hashes, and analyzes content, attributes, ownership, and permissions. On Linux, the Audit daemon can identify who caused an event and which command produced it. Events may be written locally, sent over a network, or sent to both destinations. Documentation lists Elasticsearch 8.x or OpenSearch 2.x and Splunk indexer 9.x integrations, with only one integration active at a time. FIM runs on Linux, Windows, and macOS. Installation guidance lists Ubuntu Xenial or later, CentOS 7 or later, Windows 7 or Server 2016 or later, and macOS Big Sur or later. Minimum requirements are one CPU core, 128 MB memory, and 1 GB storage, with storage use increasing over time. The maker says support is free and provides an email contact.

Paessler PRTG Network Monitor monitors systems, devices, network traffic, applications, and other infrastructure metrics from an on-premises installation. It runs on Windows servers and includes more than 250 preconfigured sensors, each measuring one or more aspects of a device. Monitoring tools include customizable alerts, scheduled reports, distributed monitoring, and dashboards with live status information. Paessler also lists adaptive AI-driven anomaly detection and smart sensor recommendations. PRTG provides an API for monitoring data and custom features, and can send webhook notifications to Slack and Microsoft Teams. Its free iOS and Android apps display monitoring data and send push notifications, but do not support cluster setups. The free plan covers up to 100 sensors; paid plans start at $200 per month paid annually. Each server accepts one license key, so license sizes cannot be combined on a server.
