Counters are values you can increment and decrement.


Create your counter:

(use '[metrics.counters :only (counter)])

(def users-connected (counter "users-connected"))


Now increment and decrement it:

(use '[metrics.counters :only (inc! dec!)])

(inc! users-connected)
(inc! users-connected 2)

(dec! users-connected)
(dec! users-connected 2)


There's only one way to get data from a counter.


You can get the current value of a counter with value:

(use '[metrics.counters :only (value)])

(value users-connected)
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 Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
