Re: conversion problems using (count @someatom)

Your last argument is not a sequence - remove the apply.

(and you probably want to remove the conj [] on the free memory call?)

conversion problems using (count @someatom)

2012-10-29 Thread larry google groups 
I decided I wanted to be able to see some stats about my little app, so I 
added this function: 

(defn show-stats-regarding-resources-used-by-this-app [request]
  (response (apply str "Memory in use (percentage/used/max-heap): " 
(who/memory-usage) "  CPU usage (how-many-cpu's/load-average):  " 
(who/cpu-load-usage)  " free memory in jvm: " (conj [] 
(who/free-memory-in-jvm) 

This worked great, but then I decided to add this to the end:

" How many people are logged in: " (str (count @registry))

The registry is defined as: 

(def registry (atom {}))

And this map keeps maps inside of it, one for each user, so it is a 2D map. 

Now Ihave this and I get errors: 

(defn show-stats-regarding-resources-used-by-this-app [request]
  (response (apply str "Memory in use (percentage/used/max-heap): " 
(who/memory-usage) "  CPU usage (how-many-cpu's/load-average):  " 
(who/cpu-load-usage)  " free memory in jvm: " (conj [] 
(who/free-memory-in-jvm))  " How many people are logged in: " (str (count 
@registry) 

I get:

2012-10-29 12:15:02.045:WARN:oejs.AbstractHttpConnection:/show-resources
java.lang.IllegalArgumentException: Don't know how to create ISeq from: 
java.lang.Long

I tried this with and without the "str". What is wrong with this?
