I just released a custom Curl probe for smokeping.
Curl probe only fetch load time (that is, total time minus DNS resolution time). But I needed to be able to measure various response times like (extract from curl manpage):
If most of them are quite clear, some others are not that obvious. For example, time_appconnect indicate time spent in protocol negotiation before reaching the app.
And that can be used to measure SSL negotiation time !
To achieve that, I added a new configuration option
write_out, which can take on the above values. If empty, or not in the list, default Curl probe behaviour apply (total time minus DNS resolution time).
As far as I know, smokeping can only receive one value at a time. That means you have to define as much Targets as wanted timers, and do as much requests as wanted timers.
