Hi,
I Just upgraded my Redis Env's to 2.6 (from 2.2).
somehow i encounter issues regarding monitoring Redis Hitrate, getting the following Error:

CRITICAL: hitrate data is missing - REDIS

Any Idea what might be the cause?

Please run it manually with -v for debugging output to see what is going on

Attached is the Full stack Trace, please look at the Difference now (redis 2.6) when executing INFO, the stracture of output is different, can it be the cause?

Thank you for your assistant, it's much appreciated.

You need to upgrade Perl Redis library, its not separating all lines and as a result plugin is not parsing data appropriately

install Redis
exit
