Create your timer::

    (use '[metrics.timers :only (timer)])

    (def image-processing-time (timer "image-processing-time"))



Now time something::

    (use '[metrics.timers :only (time!)])

    (time! image-processing-time
           (process-image-part-1 ...)
           (process-image-part-2 ...))

`time!` is a macro.  If you need a function instead, you can use `time-fn!`, but
you'll need to pass it a function instead of just a body::

    (use '[metrics.timers :only (time-fn!)])

    (time-fn! image-processing-time
              (fn []
                (process-image-part-1 ...)
                (process-image-part-2 ...)))
Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
