+# check_solr_slave.php
+Written by [Glenn Plas](http://byte-consult.be)
+
+ - Uses curl for HTTP calls to the slave
+ - Cleans out dangerous moves (basically, it only allow GET request to be sent to a slave)
+
+## Overview
+ - This script either parses or tails a solr request log file and sends appropriate slave requests. 
+ - exits at the first error, so as long as it runs, the slave looks to respond fine
+
+## Usage
+
+1. `-i`, OR --input <value> : The input file to get the requests from (required)
+2. `-s`, OR --slave <value> : host:port ( host can be an ip or a hostname) (required)
+3. `-t`, OR --tail          : Use tail on the file so you check in realtime, otherwise it will be read from start to end
+4. `-d`, OR --debug <value> : Debug flag level. ( value range 1..6 ) => Unused for now
+
+## Gotchas
+
+Large files take a long time to process sequentially, I find the tail function a lot more interesting.  Your slave will get some hits.
+
+## Dependencies
+ - php curl !
+ - solr (duh)
+
+## Inspiration
+ - A real life problem that required me to verify if a slave was doing fine.
+## License
+
+## TODO
+ - Check the content of the responses
+ - Check the response sizes of the slave and compair them to the master (Theoretically they should be the same)
