Extend your Checkmk monitoring with packages created by community members. Or create your own packages and share the here with the rest of the community.
The AlertOps Notification Plugin provides native integration between Checkmk monitoring and AlertOps incident management. When a host or service changes state in Checkmk, the plugin sends a structured JSON payload to an AlertOps webhook endpoint, enabling automated alert routing, escalation, and incident lifecycle management.
Checkmk MKP that evaluates the cryptographic algorithms the OpenSSH daemon offers according to its effective configuration (sshd -T) For Details, see [https://github.com/Gulaschcowboy/checkmk\_extensions/tree/main/sshd\_crypto](https://github.com/Gulaschcowboy/checkmk_extensions/tree/main/sshd_crypto) The built-in SSH daemon configuration service is not touched; both services coexist.

## HPE Morpheus Monitoring for Checkmk Read-only monitoring of HPE Morpheus through its REST API. ### Features - Appliance health, CPU, JVM memory, database connections, storage and application components. - Cloud status and synchronization. - Datastore capacity, state and multipath counters. - Hypervisor CPU, memory, power and maintenance state. - Cluster status, members and HA information. - Hardware health summaries and optional individual sensors. - VM state, CPU, memory and API-reported storage through piggyback. - Utilization graphs, readable units and Perf-O-Meters. ### Compatibility Targets Checkmk 2.4. Developed against Checkmk 2.4.0p26 CME and Morpheus 9.1.0.1 with HVM. Other versions and providers require validation. Checkmk 2.5 compatibility is not claimed. ### Configuration Store a read-access API token in Checkmk's Password store and configure the HPE Morpheus rule on an API source host. Discover its services, then configure VM hosts to consume piggyback data. TLS verification is enabled by default. No customer-specific addresses or credentials are included. ### Limitations VM CPU retains the API scale and may exceed 100%. VM storage represents API-reported usage, not individual guest filesystems. Cached readings retain their original timestamps and trigger freshness warnings. ### Documentation and support [https://github.com/pwladzinski/checkmk-morpheus](https://github.com/pwladzinski/checkmk-morpheus) Maintainer: Pawel Wladzinski Contact: [pawel.wladzinski@vayana.pl](mailto:pawel.wladzinski@vayana.pl) License: GPL-2.0-only Independent community integration; not an official HPE or Checkmk product.

A Checkmk **special agent** plus check plugins to monitor GitLab through its REST API (v4) — both **self-hosted** (CE/EE) and **GitLab.com (SaaS)** — built in the style of the bundled Jenkins special agent. Tested layout for **Checkmk 2\.5.0**, GitLab EE 19.x, and tested successfully against a **GitLab.com free account**. Some services are admin- or EE-only and therefore self-hosted only — see [Compatibility](#compatibility).

Checkmk 2.5 extension that shows for every Brotli decoder on a Linux host (system libbrotlidec, Node.js, Python Brotli/brotlicffi, .NET runtime) whether it is affected by Broccoli2Shell (CVE-2026-111497): fixed by version or distribution backport, Node.js and Python extensions judged by the system library they are linked against, and processes still running a replaced decoder. Tested on 17 distribution and image setups, Checkmk 2.5 and 3.0 daily. Disclaimer I did not develop this MKP officially as an employee of Checkmk GmbH, but rather as a private individual.
