Uptime

The Uptime page tracks per-server and per-port availability over time, showing uptime percentages, hourly heatmaps, and a full downtime event log.

Time Range

Select the period to analyse using the tabs at the top: 1h · 6h · 24h · 7d · 30d.

Summary Cards

Metric	Description
Fleet Uptime	Aggregate uptime percentage across all servers and ports
Servers Monitored	Total servers included in calculations
At 100%	Count of servers with no downtime in the selected period
Degraded	Servers with at least one port outage

Per-Server Uptime

Each server has its own section showing:

• Overall uptime % for the server
• Per-port uptime % for HTTP/80, HTTPS/443, SIP-UDP/5060, SIP-TLS/5061
• Hourly heatmap — a colour-coded bar showing uptime per hour across the selected period. Each bucket represents one hour; colour intensity indicates the proportion of checks that succeeded. The number of total checks and active ports are shown below the heatmap.
• Downtime Events — a chronological list of outage events, each showing timestamp, duration, and which ports were affected

Downtime Events

Each downtime event shows:

• Timestamp — when the outage started
• Duration — how long the outage lasted (e.g. 30s, 1m)
• Affected ports — which ports were down (e.g. http, https or sipUdp, sipTls)

note

Records with a disabled status are excluded from uptime percentage calculations and heatmap rendering. Only active monitoring periods are counted.
