If you're using 0.7, I'd skip jmx and use the mx4j http interface then write scripts that convert the data to the format you need. -ryan On Wed, Feb 9, 2011 at 2:47 AM, Roland Gude wrote: > Unfortunately not, as the nagios JMX check expects a numeric return value and > only allows for defining

Hi Vishan, Aron and all, Thanks for the help. I tried it and successfully worked for me. But I could not find a place where mention about the attributes of some commands. e.g. update column family [with = [and = ...]]; create keyspace [with = [and = ...]]; (we can use comparator=UTF8Type and de
