# 1. create group and stream
# 2. add entry to stream (with index 1-0)
# 3. read it from a consumer group -> index is now pending
# 4. show group infos -> pending shows 1 pending entry
# 4.2. start Rsyslog and send message -> omhiredis acknowledges index 1-0 on group 'group' for stream 'inStream'
# 5. show group infos again -> pending now shows 0 pending entries
