Splunk Cassandra Connect

• Splunk Python SDK libs intalled or splunk-sdk-python on PYTHONPATH

• Cassandra

  • Resources:
    • $CASSANDRA_HOME/README.txt
    • http://wiki.apache.org/cassandra/GettingStarted

• pycassa 1.7.2

  • Installed in {app}/bin/pycassa

  • Installed in {app}/bin/cql

Start Cassandra Cluster and verify listening on 9160

Launch the Cassandra CLI

cd $CASSANDRA_HOME/bin
./cassandra-cli --host localhost

Get listing of available keyspaces:

show keyspaces;

edit {app}/bin/setting.py
set Cassandra Host and Port
## Note v.Next will have UI setup for multi cluster

Install universal forwarder on all cassandra nodes 
Add a splunk forwarder and this entry to /loca/inputs.conf
           [monitor:///var/log/cassandra/*] 
           index=casslogs

Verify logs are coming into the casslogs index
Run {app}/bin/python dbschema.py and verify keyspace config shows up
Run {app}/bin/python dbdiscover.py and verify all Column_Families show up

[dbcql] dbcql.py USAGE: dbcql {query} # A query may consist of multiple expressions. We execute each of # the expressions in order and output the results from the final # expression. The primary scenario is: # # "USE {keyspace}; SELECT * FROM {Column_family} WHERE {Conditions}"" #

[dbinsert] dbinsert.py Usage: dbinsert {cfpath} {key} {fields} # cfpath must be Keyspace.Column_family notation

[dblookup] dblookup.py Usage: dblookup {cfpath} {key} # cfpath must be Keyspace.Column_family notation

[dbschema] dbschema.py USAGE: dbschema << None OR Keyspace OR Keyspace Column_Family # Can use No parameters for cluster, a Keyspace or a Keyspace Column_family # dbschema ## Returns all schema information on cluster # dbschema {Keyspace} ## Returns all schema information for Keyspace = schema1 # dbschema {Keyspace} {Column_family} ## Returns all schema information for Column_Family

[dbgetkeys] dbgetkeys.py Usage: dbgetkeys {Keyspace Column_Family} # Must be run with both elements Keyspace and Column_family # Returns a complete list of Row Keys in format Keyspace,Column_Family,Key

[dbdiscover] dbdiscover.py Usage: dbdiscover # Collects all keyspaces and column_families on the cluster in
# keyspace=system,column_family=schema_keyspaces format
