When I started the server like this: (prometheus.example:run :exposer-host "localhost")

I receive following error:

curl localhost:9101/metrics
<html><head><title>500 Internal Server Error</title></head><body><h1>Internal Server Error</h1>An error has occurred<p><hr><address><a href='http://weitz.de/hunchentoot/'>Hunchentoot 1.2.38</a> <a href='http://www.sbcl.org/'>(SBCL 1.4.16)</a> at localhost:9101</address></p></body></html>

I found that most probably, the 500 error is caused by this error:

Error opening #P"/proc/self/limits": No such file or directory

I'm trying it under OSX. Probably it works under the Linux.

The way to reproduce is:

CL-USER> (ql:quickload :prometheus.examples)
To load "prometheus.examples":
  Load 1 ASDF system:
    prometheus.examples
; Loading "prometheus.examples"
.....
(:PROMETHEUS.EXAMPLES)
CL-USER> (prometheus.example:run :exposer-host "localhost")
#<PROMETHEUS.EXAMPLE::APPLICATION (host localhost, port 8700)>
CL-USER> (prom.text:marshal  prometheus.example::*example-registry*)
; Debugger entered on #<FILE-DOES-NOT-EXIST "~@<~?~@[: ~2I~_~A~]~:>" {1002E63873}>
