The project deliberately keeps the model simple: run a command, restart it on failure, optionally daemonize it, and call user-supplied scripts on restart or final error. ### Project history The tool is used more like a tiny supervisor than a full metrics system. Its README shows one mon instance per process, shell scripts as configuration, PID files and log prefixes for multiple instances, and companion tools such as mongroup for managing groups of mon processes. Homebrew packages it as a lightweight system utility for monitoring hosts, services, or arbitrary commands and alerting about problems. ### How it is used Because public sources for this particular mon package are sparse outside the upstream README and package metadata, its project history is best treated as a short package note rather than a detailed adoption narrative. ### Sources - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** mon - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Other Package-Manager Records - Debian apt - mon - 1.4.1-2: normalized package name match | Debian stable package indexes: mon from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | monitor hosts/services/whatever and alert about problems | https://doc.coker.com.au/projects/etbe-mon/ - Ubuntu apt - mon - 1.3.8-1build3: normalized package name match | Ubuntu 24.04 LTS package indexes: mon from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | monitor hosts/services/whatever and alert about problems | https://doc.coker.com.au/projects/etbe-mon/ - dnf - mon - 1.2.0-46.fc45: normalized package name match | Fedora Rawhide package metadata: mon from https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/repodata/e5ca8ce900cd68f5419e1c39ae517343100b306336cbaeb70a3c153121d95094-primary.xml.zst | General-purpose resource monitoring system | http://www.kernel.org/software/mon/ ## Related links - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Homebrew utility packages](https://www.automicvault.com/pkg/brew-utility-packages/) - Matched Homebrew package provider. - [netdata](https://www.automicvault.com/pkg/brew/netdata/) - Shares av.db curated category or tags: alerts, cli, monitoring, system. - [zabbix](https://www.automicvault.com/pkg/brew/zabbix/) - Shares av.db curated category or tags: alerts, cli, monitoring, system. - [asitop](https://www.automicvault.com/pkg/brew/asitop/) - Shares av.db curated category or tags: cli, monitoring, system. - [collectd](https://www.automicvault.com/pkg/brew/collectd/) - Shares av.db curated category or tags: cli, monitoring, system. - [ctop](https://www.automicvault.com/pkg/brew/ctop/) - Shares av.db curated category or tags: cli, monitoring, system. - [duf](https://www.automicvault.com/pkg/brew/duf/) - Shares av.db curated category or tags: cli, monitoring, system. - [dwatch](https://www.automicvault.com/pkg/brew/dwatch/) - Shares av.db curated category or tags: cli, monitoring, system. - [gotop](https://www.automicvault.com/pkg/brew/gotop/) - Shares av.db curated category or tags: cli, monitoring, system. - [btop](https://www.automicvault.com/pkg/brew/btop/) - Local package facts share a topical domain.
