JavaMelody - Monitoring Free Disk Space in JSON or XML

Question

I am using Tomcat and Javamelody and need the "Free Disk Space" of the machine. In the normal web view there is a table row for that, but in XML or JSON output (format=xml) this value is missing ?! Is this is bug? How can i get the free disk space without modifying my java app ?

Answer 1

Si, the free disk space is in the xml/json.

You can find it in the response of the http requests:

.../monitoring?format=xml&part=jvm or .../monitoring?format=json&part=jvm

Or you can just get the last value in the free disk space graph, without other data:

.../monitoring?part=lastValue&graph=Free_disk_space
