Troubleshooting
Reads are getting slower while writes are still fast
Nodes seem to freeze after some period of time
Nodes are dying with OOM errors
Nodetool or JMX connections failing on remote nodes
Handling schema disagreements
View of ring differs between some nodes
Lost communication due to firewall timeouts

Cassandra tools
SSTable utilities
SSTable utilities
sstableexpiredblockers
The sstableexpiredblockers utility will reveal blocking SSTables that prevent an SSTable from dropping.
sstablekeys
The sstablekeys utility dumps table keys.
sstablelevelreset
The sstablelevelreset utility will reset the level to 0 on a given set of SSTables.
sstableloader (Cassandra bulk loader)
Provides the ability to bulk load external data into a cluster, load existing SSTables into another cluster with a different number of nodes or replication strategy, and restore snapshots.
sstablemetadata
The sstablemetadata utility prints metadata about a specified SSTable.
sstableofflinerelevel
The sstableofflinerelevel utility will relevel SSTables.
sstablerepairedset
The sstablerepairedset utility will reset the level to 0 on a given set of SSTables.
sstablescrub
An offline version of nodetool scrub. It attempts to remove the corrupted parts while preserving non-corrupted data.
sstablesplit
Use this tool to split SSTables files into multiple SSTables of a maximum designated size.
sstableupgrade
Upgrade the SSTables in the specified table or snapshot to match the currently installed version of Cassandra.
sstableverify
The sstableverify utility will verify the SSTable for a provided table.
sstable2json
Converts the on-disk SSTable representation of a table into a JSON formatted document.
json2sstable
Converts a JSON representation of a table (aka column family) to a Cassandra usable SSTable format.
