Golang a simple way to record the time-consuming function execution.

This is a creation in Article, where the information may have evolved or changed.

Write a public function first, such as a method under the common package:

Write Timeout warning Log general method

Func timeoutwarning (tag, detailed string, start time.) Time, TimeLimit float64) {

Dis: = time. Now (). Sub (Start). Seconds ()

If dis > timelimit {

Log. Warning (log. Center_common_warning, Tag, "Detailed:", detailed, "timeoutwarning using", Dis, "s")

PUBSTR: = Fmt. Sprintf ("%s count%v, using%f seconds", tag, count, dis)

Stats. Publish (tag, pubstr)

}

}

Several parameters of this function are described below:

• The tag, detailed, represents two string arguments for where the timeout occurred.
• Time the Start program started executing
• The TimeLimit function executes a timeout threshold in seconds.

When used, the first line of each function has the following code:

//

Func Save function name (...) (...) {

If this method executes for 3 seconds, the log is logged

Defer common. Timeoutwarning ("Saveapplogmain", "Total", time. Now (), float64 (3))
    ... The logic of the function itself.

}
