Available on all Uptrends plans. When Uptrends detects an error on your website or server, we always perform a double check on another checkpoint to verify the error. This is why during downtime, you always see a pattern of unconfirmed errors and confirmed errors in your website monitoring dashboards. The way we calculate uptime is easy to understand: we take the number of seconds that your monitor was down in a certain time frameand divide this by the total number of seconds your monitor was being monitored during that time frame.
Pretty simple, ain't it? Let's jump into an example. Let's say we monitored a website during 24 hours which translates to 86, secondsand in that timeframe the website went down for 10 minutes seconds.
To define the uptime and downtime percentages, we perform the following calculation:. Total number of seconds your website was down: seconds. Total number of seconds your website was monitored: 86, We divide by 86, which is 0. In percentages, this is 0. This is the downtime percentage. We hear you thinking: but how do you mark the time between different monitor statuses OK, unconfirmed error and confirmed error?
Is the time between an unconfirmed error and a confirmed error being considered as up, or down? You're right, this can seem a bit complicated at first, but actually it isn't.Pre essay writing steps lyrics meaning of
Let us walk you through all the transition periods, and explain how those periods contribute towards uptime and downtime. OK to unconfirmed error The time between the two measurements is being considered as upbecause we are not sure there is an actual error.
For that, a double-check needs to be performed. Unconfirmed error to confirmed error The time between the two measurements is being considered as down, because the error is now confirmed. Confirmed error to unconfirmed error The time between the two measurements is being considered as down, because the monitor is still in an error condition.
A monitor will be in error until we detect an OK indication. Confirmed error to OK The time between the two measurements is being considered as down. We start considering a monitor to be up from the moment we detect an OK indication. Unconfirmed error to OK The time between the two measurements is being considered as upbecause we are not sure there is an actual error. When you pause a monitor, this time is being registered as unknown. When the uptime percentage is being calculated, please keep in mind that we include the total number of unknown seconds as well, and mark the unknown time as uptime.ResearchGate is a European commercial social networking site for scientists and researchers  to share papers, ask and answer questions, and find collaborators.
