Checkmk
· #437 most-usedYour infrastructure, monitored and acted on automatically
Checkmk is an open-source IT infrastructure monitoring platform that tracks hosts, services, metrics, and alerts across servers, containers, Kubernetes clusters, and cloud environments. Connect it to Actionist and your agents can list hosts, acknowledge problems, schedule downtimes, discover services, pull metric history, and update notification rules — all in plain English, all without opening the Checkmk UI. Turn monitoring data into automated incident response.
Eliminates manual work. Agents eliminate the manual steps between a Checkmk alert firing and the right action being taken — acknowledging problems, scheduling downtimes, creating tickets, and updating status pages without human relay.
What your Checkmk agent runs on autopilot
A week of scheduled jobs your Actionist agent will execute on your behalf.
Checkmk × every other app you use
End-to-end automations that span multiple apps — each one a real business outcome.
SLA breach alert to customer in 60 seconds
When a critical service email arrives flagging a monitored host, your agent reads the sender's account record, pulls the current Checkmk service state and metric history for their infrastructure, schedules a downtime window to prevent alert noise during investigation, and fires a personalised status email to the customer — all before the first support engineer has opened their laptop. SLA breach notifications that previously took 15 minutes of manual coordination now land on the customer's screen in under a minute.
Time saved for your team — every week, on autopilot
Savings
What your team gets back — two angles: what you stop doing manually, and what that's worth.
What you do manually today
What your agent runs for you
- Sales19 min / weekManual demo prep
A sales engineer spends 20 minutes before each prospect demo manually pulling host counts, service states, and uptime figures from Checkmk to populate the demo health sheet.
Sales Agent0 minAgent generates the demo sheetWhen a demo-prep request lands in Slack, the agent queries Checkmk, writes the health summary to the sheet, and books the prep call — before the engineer has clicked anything.
- Marketing14 min / weekDelayed status updates
When infrastructure issues affect customer-facing services, marketing waits 15+ minutes for engineering to confirm the scope before updating the public status page.
Marketing Agent0 minAgent posts to status page in 2 minutesThe agent queries Checkmk for service state on report and commits a status-page incident update to GitHub Pages before the first customer follow-up email arrives.
- Customer Support19 min / weekAlert-to-customer lag
Support engineers manually cross-reference Checkmk alerts with customer accounts before sending incident notifications, adding 10–20 minutes to every customer-facing outage response.
Customer Support Agent0 minAgent notifies customer in 60 secondsThe agent reads the service state, schedules a downtime, and sends a personalised customer email automatically when a support-flagged incident arrives in the inbox.
- Human Resources8 min / weekManual on-call load audit
HR relies on engineering managers to self-report on-call burden; there is no systematic way to check whether the notification load is distributed fairly across team members.
Human Resources Agent0 minAgent reports notification distributionThe agent lists Checkmk notifications per engineer each week and flags anyone receiving disproportionately high page volume, feeding directly into the wellbeing review.
- Finance14 min / weekSLA data gathering
Finance spends two hours at month-end manually extracting downtime records, matching them to approved maintenance windows, and calculating uptime percentages for customer SLA reports.
Finance Agent0 minAgent assembles SLA report on day oneWhen the monthly SLA Notion page is created, the agent pulls metric history and notification logs from Checkmk and populates the report automatically, including flagging any breach requiring a credit.
- Operations30 min / weekManual host registration
Every new server requires an ops engineer to manually create the host in Checkmk, trigger service discovery, and activate changes — a 15-minute process that is easy to forget during busy provisioning runs.
Operations Agent0 minAgent monitors every server from minute oneWhen a new row appears in the inventory sheet, the agent creates the host, runs discovery, activates changes, and logs the result to Notion — fully automated, zero clicks.
- Legal6 min / weekCompliance evidence export
Legal manually requests notification logs from the ops team for each audit cycle, then waits days for someone to extract and format the data from Checkmk into a presentable CSV.
Legal Agent0 minAgent exports audit evidence on requestThe agent lists Checkmk notifications for the audit period, filters for critical-host events, and exports a timestamped CSV proving every CRIT triggered an alert — delivered in minutes, not days.

How to plug Checkmk into Actionist
Pick the connection method that suits your environment.
The fastest path to full Checkmk automation. Install the Checkmk MCP server and the agent connects to your site through a permissioned handshake — list hosts, acknowledge problems, and schedule downtimes without managing API tokens or site URLs manually.
Find Checkmk in the Apps library and click Connect. MCP is selected by default.
Enter your Checkmk site URL (e.g. https://monitoring.yourcompany.com/mysite) and grant the Actionist MCP server read and write access to the REST API. A dedicated automation user with the least required permissions is recommended.
Actionist runs a read-only call to list hosts and verify the handshake. You're ready when the host count appears.
