What does the 0 stand for in euca-describe-instances

Asked by Torsten Spindler

$ euca-describe-instances
RESERVATION r-41D60754 admin default
INSTANCE i-533F089B emi-E1F114F0 pending admin 0 c1.medium 2010-03-19T10:58:27.813Z torsten eki-24E019F0 eri-032D196E

I can make sense of most of the output of euca-describe-instances, but the meaning of 0 between admin (user) and c1.medium (machine type) is unknown to me. Any idea what it means? man euca-describe-instances is not very helpful for parsing the output.

It is the instance index. If you start more than one instance at a time (ie, euca-run-instances -n /n/ ...), each instances will have a different index (from 0 to /n/).
