Hi Ali. You should run it like this java -cp "/home/ali/apache-cassandra-0.6.3/lib/*" com.google.code.scm.CassandraMonitoring localhost ks1:cf1,ks2:cf2,etc I forgot to mention it has been coded against 0.7.x, and I'm not sure it will work on 0.6.x. I'll try to add support for both 0.6.x and the new 0.8.x version as soon as possible. > > On 04/12/2011 07:26 PM, Héctor Izquierdo Seliva wrote: > > Hi everyone. > > > > Looking for ways to monitor cassandra with zabbix I could not found > > anything that was really usable, till I found mention of a nice class by > > smeet.
