Question: how to replace multi pattern

[keyboardfann]

When I use string replace, seems the last pattern valid. I want to replace / to "." and replace "/value" to "". How do I have multi patterns to replace the string.

My expect Result:

stats_counts.MGS_fanntest.fanntest1
stats.gauges.MGS_fanntest.fanntest1
stats.timers.MGS_fanntest.fanntest1.90_percentile
stats.timers.MGS_fanntest.fanntest1.count
stats.timers.MGS_fanntest.fanntest1.lower
stats.timers.MGS_fanntest.fanntest1.mean
stats.timers.MGS_fanntest.fanntest1.stddev
stats.timers.MGS_fanntest.fanntest1.upper

replace / to "."

When you do

        service (clojure.string/replace (:service event) #"/" ".")
        service (clojure.string/replace (:service event) #"/value" "")

service will always be the result of (clojure.string/replace (:service event) #"/value" "").

Try to do instead something like:

        service (clojure.string/replace (:service event) #"/value" "")
        service (clojure.string/replace service #"/" ".")

I invert the 2 regex because you don't want to have ".value".

You can also probably do

        service (-> (clojure.string/replace (:service event) #"/value" "")
                    (clojure.string/replace #"/" "."))

Or do it in one regex ;)

Dear @mcorbin,
After change to the following setting , everything look good. Thank you for the answer.

  (let [;; replace /value by "" , replace all "/" by "." in service
        service (-> (clojure.string/replace (:service event) #"/value" "")
                    (clojure.string/replace #"/lower" ".lower")
                    (clojure.string/replace #"/count" ".count")
                    (clojure.string/replace #"/90_percentile" ".90_percentile")
                    (clojure.string/replace #"/mean" ".mean")
                    (clojure.string/replace #"/stddev" ".stddev")
                    (clojure.string/replace #"/upper" ".upper")
         )

[root@tng1524 ~]# date;echo "MGS_fanntest.fanntest1:100|ms|@0.1" | nc -w 1 -u x.x.x.x 12000
