Summarize with ChatGPT Claude To get alerted when a server goes down, run a check from outside the server and send its result to a channel that reaches a human. That check can be a cron script on a second machine that pings the host and tests a port, an external ping or TCP port monitor, or an agent on the server whose silence opens an incident. Email and Slack are fine for the record. For a server that matters at 3am, the alert has to escalate to SMS and then a phone call when nobody acknowledges it.

Summarize with ChatGPT Claude To monitor an Ubuntu server, watch seven things: CPU, load average, memory, disk space, disk I/O, network and whether the machine is up at all. You can check all of them in under a minute with commands that ship with Ubuntu (top, free, df, vmstat) plus iostat from the sysstat package. That is fine while you are logged in.

Summarize with ChatGPT Claude The Hyperping MCP server now has 49 tools: 28 that read and 21 that write. An agent connected from Claude Code, Cursor, Codex or another MCP client could already manage monitors, publish a status page incident and schedule maintenance. It can now do most of the rest: declare an incident and page on-call, acknowledge and escalate it, correct what was posted on the status page, create and configure status pages, and reschedule, end or cancel maintenance.

Status pages now have a place for the last step of an incident: the post-mortem. Once an incident is resolved, you can write what happened, why it happened, and what you are changing, then publish it on the incident itself. Until now, the updates you posted during an outage ended with "Resolved", and the explanation lived somewhere else: a blog post, a PDF sent to a few customers, or an email thread. Customers who read the incident on your status page never saw it.

The best DNS monitoring tools are Hyperping for fast DNS checks with on-call and a status page, Oh Dear for authoritative nameserver comparison and change history, Site24x7 for DNSSEC and global locations inside a suite, UptimeRobot for inexpensive DNS checks next to HTTP, and DNS Spy for dedicated DNS security and WHOIS. I analyzed 24 current products and shortlisted five. Every tool below can query DNS on a schedule and alert when the answer is missing or wrong.

The best API monitoring tools are Hyperping for HTTP and API checks with on-call and status pages, Checkly for API monitoring as code, Postman Monitors for teams that already keep collections in Postman, Datadog for connecting failed checks to traces and logs, Grafana Cloud for teams using k6, Better Stack for checks inside a broader incident workflow, and UptimeRobot for inexpensive availability checks.
