check_solr_slave.php

Written by Glenn Plas

• 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

./check_solr_slave.php -i /var/log/jetty/2013_01_04.request.log -s 192.168.128.31:8080 -t

1. -i, OR --input <value> : The input file to get the requests from (required)
2. -s, OR --slave <value> : Format is 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)
