Description

Not sure which Component fits for this?!

Calling /admin/mbeans?stats=true&wt=json normally gives this for an entry:

"/admin/mbeans": {
  "class": "org.apache.solr.handler.admin.SolrInfoMBeanHandler",
  "version": "5.0.0.2013.01.22.17.57.48",
  "description": "Get Info (and statistics) for registered SolrInfoMBeans",
  "src": "$URL: https://svn.apache.org/repos/asf/lucene/dev/trunk/solr/core/src/java/org/apache/solr/handler/admin/SolrInfoMBeanHandler.java $",
  "stats": {
    "handlerStart": 1358960935983,
    "requests": 16,
    "errors": 0,
    "timeouts": 0,
    "totalTime": 238.636824,
    "avgRequestsPerSecond": 0.0010339617096334008,
    "5minRateReqsPerSecond": 0.009435751279543023,
    "15minRateReqsPerSecond": 0.008764046777884586,
    "avgTimePerRequest": 15.909121599999999,
    "medianRequestTime": 15.43261,
    "75thPcRequestTime": 16.544159,
    "95thPcRequestTime": 24.570421,
    "99thPcRequestTime": 24.570421,
    "999thPcRequestTime": 24.570421
  }
},

but for instances of DataImportHandler it looks like this:

"/dataimport": {
  "class": "org.apache.solr.handler.dataimport.DataImportHandler",
  "version": "5.0.0.2013.01.12.19.48.17",
  "description": "Manage data import from databases to Solr",
  "src": "$URL: https://svn.apache.org/repos/asf/lucene/dev/trunk/solr/contrib/dataimporthandler/src/java/org/apache/solr/handler/dataimport/DataImportHandler.java $",
  "stats": [
    "Status",
    "IDLE",
    "Total Documents Processed",
    "java.util.concurrent.atomic.AtomicLong:0",
    "Total Requests made to DataSource",
    "java.util.concurrent.atomic.AtomicLong:0",
    "Total Rows Fetched",
    "java.util.concurrent.atomic.AtomicLong:0",
    "Total Documents Deleted",
    "java.util.concurrent.atomic.AtomicLong:0",
    "Total Documents Skipped",
    "java.util.concurrent.atomic.AtomicLong:0",
    "handlerStart",
    1358960935773,
    "requests",
    1,
    "errors",
    0,
    "timeouts",
    0,
    "totalTime",
    0.946654,
    "avgRequestsPerSecond",
    0.00006892979803330725,
    "5minRateReqsPerSecond",
    8.281462403544473e-23,
    "15minRateReqsPerSecond",
    3.2421452678347006e-10,
    "avgTimePerRequest",
    0.946654,
    "medianRequestTime",
    0.946654,
    "75thPcRequestTime",
    0.946654,
    "95thPcRequestTime",
    0.946654,
    "99thPcRequestTime",
    0.946654,
    "999thPcRequestTime",
    0.946654
  ]
},

if i recall another issue correctly, that has something to do with using (or otherwise not using) SimpleOrderedMap oO
