Read uptime and performance reports

The Report menu shows how each website and server has performed: how much of the time it was up, every outage, and how quickly it responded.

Choose the period

Section titled “Choose the period”

Every report page starts with the same period controls:

  • Predefined Period: from Last 24 Hours to Last 365 Days, calendar periods such as This Month or Last Year, or All Time.
  • Custom Period: pick a start and end date, then select Show.

Reports use your account’s time zone, set under Account > Account Settings.

One test in detail

Section titled “One test in detail”

Report > Overview shows one website or test at a time; choose it under Now Showing. You can also open it by selecting a website’s report icon on Monitoring Overview.

  • Uptime: the current status, the time of the next check, the uptime percentage with and without maintenance, the total maintenance and downtime, the number of outages and how long the test has been monitored.
  • Outage History: each outage with its start and end time, length, the error found and how many monitoring locations confirmed it. It has its own Download as CSV button.
  • Detailed Log: every check, with the time, the monitoring location, the error if it failed and the response times. View Response shows what the website sent back.
  • Monthly Report: uptime, downtime and outages for each month, and the total for the year.
  • Performance: the average response time, split into the stages described below.

All tests side by side

Section titled “All tests side by side”

Report > Uptime Report lists every website and test with its uptime, uptime including maintenance, total downtime and number of outages for the period, with links to each one’s outage history, detailed log and monthly report. The last row is the average across all of them.

The Uptime Report table, listing a website test and four server tests with their uptime percentage, uptime including maintenance, downtime, outage count and links to Outage History, Detailed Log and Monthly Report, followed by an AVERAGE row and the Download as CSV button.

Report > Performance Report lists the average response times of every test in the same way.

Select Download as CSV below either table to open the figures in a spreadsheet, for example to keep a record before you remove a test.

What the performance figures mean

Section titled “What the performance figures mean”

Website, HTTP and HTTPS tests split each check into stages:

Figure Time taken to
Redirect Follow any redirects to the final URL
DNS Look up the IP address of the hostname (0 if you monitor an IP address)
Connect Open a connection to the server
Request Send the request
Processing Receive the first byte of the response after sending the request: how long the site takes to build the page
Download Receive the rest of the response: an indication of available bandwidth
Total All of the above

Port tests (such as SMTP or SSH) report DNS, Connect and Response, the time to receive the service’s reply. Ping tests report RTT, the round trip time of a packet, and Packet Loss.

A high Processing time usually points to the website itself, such as slow code or database queries. High DNS or Connect times point to name servers or the network.

When UptimeHawk and your host disagree

Section titled “When UptimeHawk and your host disagree”

UptimeHawk checks your site from several locations on the internet, so it also sees network problems between your visitors and your server. A host that monitors from inside its own data centre will not see those, and may leave planned work out of its figures. Short outages that only one region saw are real for visitors in that region, even if you could reach the site at the time.

If an outage looks wrong, open the test’s Detailed Log, then contact Sheernox support with the test name and time.
