| Subject: | Info hash is erroneous |
To begin with, my apologies if I sound like a n00b. This is my first time with perl.
My sysadmin was trying to use the check_redis plugin for Nagios (https://github.com/willixix/WL-NagiosPlugins/blob/master/check_redis.pl) and was using libredis-perl from Ubuntu repo (http://manpages.ubuntu.com/manpages/karmic/man3/Redis.3pm.html) but was unable to get it going as it said used_memory_rss was not found. I then installed Redis from cpan directly and got it working correctly.
I wrote a script to dump the info hash and I saw that the values and keys were swapped in many places, ie instead of key => val it had val => key. Also, some other issues were there as well like used_memory_human and used used_memory_rss values were also swapped. I've pasted the dump of the info hash below for your reference :
