Return variables

Returns an associative array, keyed on the day.  Each day is broken down into five arrays.  Each item in the five arrays all correspond with each other (so valid[0] and errmsg[0] and servers[0]... all correspond).

This call returns data for every minute.  The example has been truncated for easy reading.

• snaptime - The time the uptime check was done.  Usually every minute.
• loadtime - The number of milliseconds it took for the page to be returned to the server.
• valid - (possible values: 1 or 0).  1 if the page returned with no errors, 0 otherwise.
• errmsg - The error message returned when trying to get the page.  Blank if no error.
• servers - The number of chartbeat servers that verified the uptime.  "loadtime" is the average between these servers.  A page will only be returned as invalid if all servers received the same error message at the same time.
