What error monitoring tracks

Error monitoring captures and groups runtime failures so teams can see which application issues are happening, recurring, or spiking.

Application error events

Error levels

Grouped duplicate issues

First seen and last seen timestamps

Occurrence counts

Why it matters

Application errors are often the earliest sign of a bad release or customer-impacting bug. Grouping and alerting make them easier to prioritize.

Users do not always report bugs clearly or quickly

Repeated errors need grouping, not raw logs

Error spikes can indicate broken releases

How it works in DownCTL

Error monitoring helps bridge client website health, application quality, and support triage.

1 Install the JS or PHP SDK
2 Send errors into DownCTL
3 Review grouped issues by site
4 Alert when error rules trip

Uptime monitoring

Uptime Monitoring

DownCTL checks client websites continuously, records response history, and alerts your team when downtime or slow responses need attention.

API monitoring

API Monitoring

DownCTL checks API and form endpoints, then validates expected responses so successful status codes do not hide broken integrations or client-site behavior.

Incident alerting

Incident Alerting

Create reusable channels and route each client-site alert rule to the people and tools that should know first.

Server performance monitoring

Server Performance Monitoring

DownCTL brings server performance metrics into the same client-site dashboard as uptime, alerts, and incidents so you can diagnose reliability problems faster.
