Monitoring for DevOps and SRE teams

Confirm the outage before you page the on-call engineer.

PulseStack checks from multiple locations, re-verifies every failure before it fires, and routes real incidents straight into PagerDuty and your webhooks. Fewer 3am pages for network blips. Faster response when it is genuinely down.

Free plan, no card required. 30 second checks on Enterprise.

The alerting problems that erode trust in your monitoring

When the pager cries wolf, people stop listening. That is the real cost of noisy monitoring, and it is where infrastructure teams lose the most.

01

One flaky route pages everyone

A single monitoring node hits a bad hop and your whole rotation gets woken for a site that was never actually down.

02

Alert fatigue kills response time

After enough false alarms, engineers mute channels and swipe pages away. The one real incident slips through the same reflex.

03

Deploys trigger their own alerts

A planned rollout throws 502s for ninety seconds and the tooling treats it as an emergency, drowning the change in noise.

04

'Site down' with no context

A bare failure alert tells you something broke but nothing about why, so the first ten minutes go to reproducing what happened.

05

Cron jobs fail silently

A nightly batch stops running and nobody notices until the downstream data is wrong, because nothing was watching the job itself.

06

Fragmented tooling

Uptime in one tool, SSL in another, DNS somewhere else. Correlating an incident across three dashboards wastes the minutes that matter.

From check to confirmed incident

Every alert PulseStack sends has already survived a verification step. Here is the path a failure takes.

1

Check from many locations

Each monitor runs on its interval from multiple geographic regions in parallel.

2

Re-verify a failure

A failing region is cross-checked against the others before anything is declared. Isolated blips are dropped.

3

Open an incident

Confirmed failures are grouped into one incident with a start time and the list of confirming locations.

4

Route and recover

Alerts fire to your channels on failure and again on recovery, with the whole timeline kept in incident history.

On-call routing that fits how you already work

A confirmed incident does not just light up a dashboard. It goes where your team lives. Send critical services to PagerDuty for the rotation, push a summary into Slack or Microsoft Teams for visibility, and fire a webhook to trigger your own automation or runbooks.

  • Failure and recovery notifications on the same monitor
  • Consecutive-failure threshold to hold back a single blip
  • Webhooks to drive automated remediation
  • Maintenance windows to silence planned changes

Eight monitor types for real infrastructure

Web endpoints are only part of the stack. Watch internal services, jobs and records with the check that fits each one.

HTTP

Custom headers

Status codes, response time and redirects on any URL

API

Custom headers

Authenticated endpoint checks with request bodies

TCP Ping

Reachability of any host on the network

Port

Watch database and service ports stay open

Heartbeat

Dead man switch for cron and batch jobs

Keyword

Confirm expected text renders on the page

DNS

Track record changes and detect drift

Domain Expiry

Advance warning before a domain lapses

What DevOps teams get out of the box

No agents to babysit, no separate tools to stitch together. The capabilities that matter for infrastructure observability are built in.

  • Multi-location checks
  • Failure re-verification
  • PagerDuty routing
  • Custom webhooks
  • Slack and Teams alerts
  • Incident detection
  • Incident history
  • Maintenance windows
  • Server diagnostics (Team+)
  • Consecutive-failure threshold
  • Recovery notifications
  • Heartbeat for cron jobs
  • Custom headers on HTTP and API
  • DNS record monitoring
  • Public status pages
  • 30s intervals (Enterprise)

Eight ways to reach the right person

Route each monitor to the channels your team actually watches. SMS and voice are available as an add-on on Team and Enterprise.

Email SMS Slack Microsoft Teams Discord PagerDuty Telegram Webhooks

Built for the checks you run every day

API + headers

Internal API health

Point API monitors with custom auth headers at your internal endpoints and catch a 500 before the dependent service does.

Heartbeat

Cron and batch jobs

Heartbeat monitors expect a ping on schedule. Miss the window and PulseStack raises the alarm instead of the missing data doing it for you.

Port + TCP

Database and service ports

Port and TCP Ping monitors confirm the ports your services depend on are open and reachable, not just that the front page loads.

Maintenance

Deploy verification

Set a maintenance window for the rollout, then let the checks confirm the service came back healthy across every location.

SSL + Domain

Certificate and domain expiry

SSL and Domain Expiry monitors give advance warning so a lapsed cert never becomes an incident of its own.

Team+

Root cause context

On Team and above, server diagnostics attach host-level context to a failing check so triage starts with a lead, not a blank page.

Noisy monitoring versus verified monitoring

An honest look at what changes when every alert has to earn its way to your pager.

Questions from infrastructure teams

How does PulseStack stop false positives waking my on-call?

Checks run from multiple locations, so a single failing region is confirmed against the others before an incident is raised. You can also set consecutive-failure thresholds and use maintenance windows to silence planned work.

Can I route alerts to PagerDuty and our own tooling?

Yes. PulseStack supports 8 alert channels including PagerDuty, webhooks, Slack, Microsoft Teams, Discord, Telegram, email and Zapier, so you can page on-call and fan events out to your own automation.

What check interval can DevOps teams get?

Paid plans check every 60 seconds. The Enterprise plan (£149/mo) runs 30-second intervals across 200 monitors with 5 seats. The Free plan checks every 5 minutes.

Do you keep incident history?

Yes. PulseStack includes incident detection and history alongside public status pages, maintenance windows and multi-location checks, so you can review what happened after the fact.

Are server diagnostics included?

Server diagnostics are available on the Team plan (£79/mo, 100 monitors, 3 seats) and Enterprise. Pro and above also add SSL certificate, DNS record and domain expiry insight modules.

How do maintenance windows work?

Schedule a maintenance window around planned deploys or infra work and PulseStack suppresses alerts for that period, so expected downtime does not page the team or dent your status page.
