PagerDuty is the industry leader in on-call incident management. Teams that have outgrown basic email alerts use PagerDuty for escalation policies, on-call rotations, incident timelines, and SLA tracking.
But PagerDuty needs a monitoring source to trigger its alerts. This guide explains how Vigilmon and PagerDuty work together, and whether you need PagerDuty at all.
What PagerDuty Is
PagerDuty is an incident management platform. It receives alerts from monitoring tools, applies escalation rules, pages the right person, and tracks incident resolution.
PagerDuty is NOT a monitoring tool — it does not check whether your site is up. It needs something upstream (Vigilmon, Datadog, CloudWatch, etc.) to detect the problem and send the alert.
PagerDuty excels at on-call rotation scheduling, escalation policies, incident management workflows, post-incident analysis, and multiple alert source aggregation.
What Vigilmon Does
Vigilmon monitors your endpoints externally and alerts you when they fail. The alerting side of Vigilmon is built for small-to-medium teams: Slack, email, and webhook alerts, alert routing by monitor group, alert escalation, and on-call schedules with team members.
For many teams, Vigilmon's built-in alerting replaces the need for PagerDuty entirely.
Using Vigilmon with PagerDuty
If your team already uses PagerDuty, Vigilmon integrates via webhook:
- In PagerDuty, create a new Integration for your service using Events API v2
- Copy the integration key
- In Vigilmon, add a webhook alert channel with the PagerDuty Events API URL and your integration key
Vigilmon sends incidents to PagerDuty, which then handles on-call routing and escalation. You get the best of both: Vigilmon's multi-region external monitoring and PagerDuty's sophisticated incident management.
Feature Comparison
Vigilmon handles external uptime checks, multi-region monitoring, status pages, basic on-call schedules, and basic escalation. Vigilmon has a free tier.
PagerDuty does not perform external checks or monitoring — it manages alerts from upstream sources. PagerDuty excels at advanced on-call scheduling, escalation policies, comprehensive incident management, SLA tracking, and multi-source aggregation. PagerDuty starts at approximately $21 per user per month.
Who Needs PagerDuty?
PagerDuty makes sense when you have 5+ engineers sharing on-call rotations, your SLAs require documented escalation workflows, you aggregate alerts from multiple monitoring sources, incident postmortems are required for compliance, or you need multi-tier escalation (tier 1 to tier 2 to engineering manager).
Who Can Skip PagerDuty?
Vigilmon's built-in alerting is often sufficient for small teams of 1-4 engineers sharing on-call, simple escalation (alert Slack then email if not acknowledged), and teams that monitor primarily via HTTP uptime checks.
If you are paying for PagerDuty but your escalation policies are never actually triggered, you may be over-engineering your alerting stack.
The Cost Question
PagerDuty starts at approximately $21/user/month for the Business plan. For a 5-person team, that is $1,260/year.
Vigilmon is free for up to 50 monitors. Paid plans are significantly cheaper than PagerDuty.
For teams that only need external uptime monitoring and simple on-call routing, Vigilmon alone is the better value. Add PagerDuty when your incident management complexity warrants it.
Setting Up Vigilmon Alerting for Small Teams
Without PagerDuty, configure Vigilmon to:
- Alert your Slack channel immediately on any failure
- Send email to on-call address after 2 minutes if Slack is not enough
- Alert a backup team member after 5 minutes
This three-tier escalation covers most small team scenarios without PagerDuty costs.
Summary
PagerDuty manages incidents; Vigilmon detects them. They work well together via webhook integration. Small teams can often use Vigilmon alone without PagerDuty. Larger teams with complex on-call rotation needs benefit from both.

The distinction between Vigilmon's monitoring capabilities and PagerDuty's incident management features is crucial, as you've highlighted. I appreciate how you've outlined the scenarios where Vigilmon's built-in alerting can replace the need for PagerDuty, especially for small teams with simple escalation requirements. The cost comparison between the two services also provides valuable insight, suggesting that teams should assess their incident management complexity before deciding to add PagerDuty to their stack. Have you found that teams often over-engineer their alerting stacks by implementing PagerDuty unnecessarily, and what are some common signs that a team might be ready to adopt a more advanced incident management solution like PagerDuty?
