Monitor types

Web, API, infrastructure, and scheduled checks — fully covered.

Monitor customer pages, internal APIs, network dependencies, certificates, DNS, and jobs with one view of uptime, latency, and incidents.

HTTP & content checks

Availability, status codes, and content checks.

Confirm status and content are correct. Catch 500s, bad redirects, exposed login pages, or slowdowns before users notice.

API contract checks

Validate payloads, paths, and values.

Validate JSON structure and critical fields so breaking changes or empty/error payloads alert immediately—before users or integrations are hit.

Heartbeat & scheduled jobs

Cron jobs and workers.

Track scheduled tasks with heartbeat signals and grace windows. If a cron or worker stalls, you get last-seen context.

SSL & domain expiry

Expiry and ownership changes.

Get early warnings for SSL expiry and domain risk. Detect certificate or ownership changes before they cause outages.

DNS change tracking

Detect record drift.

Monitor critical records (A/AAAA/CNAME/MX/TXT/NS) for drift or propagation issues. Catch misconfigurations before they spread.

Port & service handshake

Critical services up.

Check reachability on key ports and basic handshakes. Catch firewall, load balancer, or middleware issues even if the site still loads.

ICMP & network health

Packet loss + latency.

Measure latency and packet loss to spot network degradation early. Surface jitter or routing issues before outages.

SOAP & legacy endpoints

Legacy services monitored.

Monitor SOAP/XML endpoints with the same rigor as modern APIs. Validate responses and key nodes so legacy integrations stay reliable.

Monitors, at a glance.

Track status, health, and latency for every endpoint in a single grid.

Core capabilities for incident-ready teams.

Alerting, collaboration, integrations, and reporting in one place.

Spot incidents faster across every service

A single view shows health, availability, and latency so you can triage in seconds,

with filters by service, severity, and tags.

Cover every critical dependency

HTTP, TCP, and heartbeat checks keep websites, APIs, and jobs in scope,

so silent failures surface before users notice.

Keep customers informed automatically

Share uptime and incident updates with stakeholders in real time,

without manual status emails or duplicated comms.

Align teams with clear ownership

Invite users and assign roles (read-only/ops/admin),

and organize monitors by projects, areas, or clients.

Feed monitoring into your workflows

Query status, events, and history for internal integrations,

dashboards, reporting, and automations.

Actionable alerts, not noise

Email, Slack, and webhook alerts include incident context

(what failed, when it started, severity, and impact) so you respond faster.

Public status page, zero effort.

Share uptime, incidents, and maintenance updates in one public link.

FAQ

Quick answers before you start.

No. You can start the 15-day trial without a credit card. Set up monitors, receive alerts, and validate the workflow first. When you are ready to keep monitoring running past the trial, you can pick a plan from your dashboard.

When the trial ends, monitoring pauses until you choose a paid plan. Your monitors, alert rules, and status pages stay saved, so you can resume immediately without rebuilding anything.

Centinela is designed to reduce noise. Use retries, grace windows, and alert routing so brief blips do not wake up your team. Alerts include context - what changed, when it started, and current impact - so you can respond faster.

Yes. Status pages can be public or private depending on the audience. Private pages work well for internal stakeholders and partners; public pages help customer trust during incidents.

Yes. Status pages support subscription-style updates so stakeholders can follow incidents and maintenance without manual follow-ups.

Yes. Notify via email, Slack, and webhooks. Microsoft Teams is supported via webhook. Delivery reliability is handled with retries and backoff to prevent dropped messages during real incidents.

Intervals depend on plan. The trial plan starts with a higher minimum interval, and paid plans unlock faster checks (down to 30 seconds on Growth and Scale). This lets you scale intensity as your coverage grows.

Centinela stores monitor events, incident timelines, and performance history based on your plan's retention window. You can export key views for reporting and reviews.

Yes. SLA reporting, incident timelines, and exportable history make it easier to support internal controls and customer compliance requests - without rebuilding reports after every incident.

You can cancel anytime from the dashboard. Your configuration remains saved so you can come back and resume quickly, and you can export key data if you need it for records.
