Utility to check size of entries in off-heap

Hi,

I have turned on off-heap cache memory settings while trying to load close
to 300 million records in to the  ignite server cluster. When I had the
cache use java heap alone, I was able to get the cache size details and
number of records using "ignitevisorcmd.sh". Once I enabled off-heap memory
settings (having an eviction policy to store maximum of 1 million records) I
can only see the size of entries in cache but not the details of the
off-heap storage. Is there a way I can check the size of entries in the
off-heap region? 

Thanks,

Thank you Denis! Not sure if "cache -a" is giving me the off-heap statistics
as well. I will try to collect the metrics using the
"org.apache.ignite.cache.CacheMetrics" interface to check this one out.

Hi Raghu,

What commands did you execute to get cache statistics using Visor 
console (ignitevisorcmd.bat)?
I've used 'cache -a' and get the same details for both on-heap and 
off-heap memory modes./

/Is there a way I can check the size of entries in the off-heap region? /

You can but under the 'size' a number of entries is meant. The number 
can be retrieved programmatically using 
'cache.metrics().getOffHeapEntriesCount()' or with a help of Visor 
console as you did before.

In general the full set of off-heap metrics is available through 
org.apache.ignite.cache.CacheMetrics interface. The off-heap related 
metrics start with 'getOffHeap...'. Visor console uses the same 
interface as far as I know.

Regards,
Denis
