# Cassandra

#### Cassandra (Metadata)

Cassandra token ring on the local CVM. Normal output: an even load of keys across the cluster. A newly added node shows as LIMBO while metadata is being redistributed

```bash
nodetool -h localhost ring
```

Same, for all CVMs at once

```bash
for i in `svmips` ; do ssh $i "source /etc/profile ; nodetool -h localhost ring" ; done
```

Column family statistics

```bash
nodetool -h 127.0.0.1 cfstats
```
