How to View Monitor Metrics

Explore response time charts, uptime statistics, SSL expiry, and historical check results for any monitor.

Opening the Monitor Detail Page

There are two ways to open the detail page for a monitor:

The detail page fetches data from the edge server that runs this monitor.

Header Summary Card

At the top of the page, a summary card shows the most important information at a glance:

FieldDescription
Monitor NameThe name you gave this monitor
StatusUp or Down, updated on every page load
Monitor Typehttp, https, ping, port, keyword, or dns
Current Response TimeRound-trip latency from the last check (ms)
Last CheckedTimestamp of the most recent check
Check IntervalHow often the monitor runs (e.g., every 5 minutes)
Target URL / HostThe URL or host being monitored (clickable link for HTTP/HTTPS)

Time Range Selector

Use the time range selector at the top of the charts section to zoom in or out:

All charts update simultaneously when you change the time range.

Uptime Statistics

The uptime percentage is shown prominently beneath the header:

For selected period

Percentage of checks in the selected period (from the time range) that succeeded.

How uptime is calculated Uptime % = (number of successful checks ÷ total checks) × 100. A check is successful if the target is reachable and returns the expected response. Paused periods are excluded from the denominator.

Charts

Response Time Chart

A line chart showing the total round-trip response time in milliseconds over the selected period. Each data point represents one check. Gaps in the chart indicate periods when the monitor was paused or the check timed out.

Status Over Time (Timeline Bar)

A color-coded horizontal bar showing Up (green) and Down (red) periods. This makes it easy to spot recurring outages or time-of-day patterns. Hover over a segment to see the exact start and end times.

TTFB — Time to First Byte (HTTP / HTTPS monitors only)

The time in milliseconds from when the request was sent to when the server sent back its first byte of response. High TTFB values indicate slow backend processing independent of network latency.

DNS Resolution Time (HTTP / HTTPS monitors only)

Time taken by the edge server to resolve the monitor's domain name. Spikes here point to DNS infrastructure problems rather than web server issues.

TCP Connection Time (HTTP / HTTPS / Port monitors)

Time to complete the TCP (and TLS) handshake. High values may indicate network congestion or TLS misconfiguration.

SSL Certificate Expiry (HTTPS monitors only)

A gauge showing the number of days until the SSL certificate expires. Color coding:

Configure an alert on SSL expiry in Configure Alerts to be notified before the certificate expires.
