I have set up the logstash to index logs to solr using solr\_http plugin and reading events using file input plugin, but when solr is down the events that are recorded in that time period are lost and logstahs solr\_http plugin throws error but this is not the case of elastic search, if elastic search is down the evnts are preserved  
Please anyone help me out foe solr\_http output, I also tried persisted queues but it also doesn't worked
