Unknown command 'CONFIG' and 'DEBUG'

[fenelon]

I'm getting the following trace. Any thoughts on the fix?

Maybe this if you are using AWS ElastiCache:

For cache clusters running Redis, the following commands are unavailable:

• bgrewriteaof
• bgsave
• config
• debug
• migrate
• save
• slaveof
• shutdown

I actually am. I guess RMA needs a flag to work without those commands if it is possible altogether. Any ideas?

@fenelon The INFO command may be the extent of what you can use. There is a redis-sampler tool that utilizes INFO, and it may provide some insight.

It definitely works on AWS ElastiCache (I use it, though not sure how easily it could be used for memory usage analysis).

What If I simply used rename-command to rename CONFIG and DEBUG to something safer? Is there any way to tell RMA to consider the new names?
