This works when the count value is changing/increasing.
In my case if the Hints total value is 10 for 2 hours, the

On 26 Feb
DIFFERENCE may not work here, if the Hints count is 10 for few hours, the
difference is always is zero. which is not the correct value.

In that case, I think that the documentation is incorrect, as it has
Service listed as the package related to the StorageService.
I apologize for the lack of the rest of the thread, everything is getting
bounced when I try to send it for some reason.

Ok. in that case I think the Docs are wrong.
http://wiki.apache.org/cassandra/JmxInterface has StorageService as part of
org.apache.cassandra.service.
Also, once I executed a CLI command, I started getting the expected output
(output being that it was able to return the live nodes).

Ideally this would be as low cost an operation on the Cassandra node as
possible, since it is just monitoring statuses (stati?).

The StorageServiceMBean is only created once some reads/writes
actually go to that node. Do a couple reads/writes from the CLI and
you should see the MBean afterwards.
This also means your monitoring application should handle this error
in the case of nodes restarting.

Good morning,
I'm trying to set up a simple monitoring application (that is a plugin to
Nagios), code can be found here:
https://github.com/so-net-developer/Cassandra/blob/master/nagios/CheckNode.java
However, when I try to run the CheckNode.java program I get an error that:
Exception in t
doing active/standby with durability guarantees. Or is this not possible
and I should use EACH_QUORUM
I found a few emails on active/standby, but nothing about monitoring, so if
this is already a discussed/solution suggested problem please forward the
link.
Thanks
Anand
