SystemInfoHandler does not expose all available info
----------------------------------------------------
Key: SOLR-3148
URL: https://issues.apache.org/jira/browse/SOLR-3148
Project: Solr
Issue Type: Bug
Affects Versions: 4.0
Reporter: Sami Siren
Priority: Minor
The following info is not returned even when they are available (on java 1.6
and 1.7):
{code}
getSystemLoadAverage()
getOpenFileDescriptorCount()
getMaxFileDescriptorCount()
getCommittedVirtualMemorySize()
getTotalPhysicalMemorySize()
getTotalSwapSpaceSize()
getProcessCpuTime()
{code}
This is happening because the following exception is thrown:
{code}
java.lang.IllegalAccessException: Class
org.apache.solr.handler.admin.SystemInfoHandler can not access a member of
class com.sun.management.UnixOperatingSystem with modifiers "public native"
{code}
It seems to be enough to call setAccessible(true) on the method to get rid of
that exception.
Additionally I see a strange value for the ulimit key:
"ulimit":"(error executing: ulimit -n)",
