Am not sure on the Ganglia side, but seeing the code i found this
{code}
// For measuring number of checksum failures
static final AtomicLong checksumFailures = new AtomicLong();
{code}
And it was getting updated too. Let me check on the JMX side if it really
getting sent out to the Metrics system. If not we can address that in the
JIRA.
