redis_exporter: Error 500 on /metrics page with Google Cloud Memorystore

Describe the problem Redis_exporter is configured to monitor Google Cloud Memorystore based on Redis. When i try to get the /metrics page, i have an error 500 as result.

EDIT: The CONFIG command is blocked by Google in their redis version

What version of redis_exporter are you running? [ ] 0.3x.x [X] 1.x.x https://github.com/oliver006/redis_exporter/releases/download/v1.2.1/redis_exporter-v1.2.1.linux-amd64.tar.gz

Running the exporter /usr/local/bin/redis_exporter --redis-only-metrics --include-system-metrics --redis.addr=X.X.X.X

Expected behavior The /metrics page available and accessible.

EDIT: Do not throw an exception if the CONFIG command or another doesn’t work

Did you upgrade from 0.3x.x to 1.0 and are scraping multiple hosts? No
