Monit to check Solr status via its API

[dvalfre]

It should be possible to extend Monit configuration for Solr by adding an HTTP query. A HTTP response other than 200 should mean it's down, although processing the output will be nicer :)

Solr-test-host ~ # curl "http://localhost:8983/solr/admin/ping?wt=json&indent=on"
{
  "responseHeader":{
    "status":0,
    "QTime":3,
    "params":{
      "q":"solrpingquery",
      "indent":"on",
      "wt":"json",
      "echoParams":"all",
      "distrib":"false",
      "df":"text",
      "rows":"10"}},
  "status":"OK"}
Solr-test-host ~ #

With the introduction of cores in Solr 5, the ping url is now

curl "http://localhost:8983/solr/<core-name>/admin/ping?wt=json&indent=on"
