Hi Colin,
You should use TotalAllocatedPages if you have persistence disabled.
There is an know issue with PhysicalMemoryPages:

Thank you,

Thanks for this. The referenced post mentions AllocatedPages rather than
PhysicalPages. Which would you advise is the most appropriate for this
application?

Hi Colin,
Unfortunately, you can't get the exact off-heap size.
There are several tickets here

I have given this (pages * pageSize * pagesFillFactor) a go now, but it
doesn't seem to be returning the values I'm expecting. In particular, the
value can drop significantly even when data is being inserted into the
cache.
Am I using pagesFillFactor incorrectly?

Please ignite my above comment, I am now able to retrieve the factor.
As such, is the following correct?
memoryUsed = pages * pageSize * pagesFillFactor

I can confirm that I have metrics enabled for my region - I am able to read
allocatedPages, it's just the fillFactor that always seems to return zero.
Colin.

Collin,
To be able to see data region metrics, you should enable them either in
configuration, or via MXBean.
You can find a note about it here:
https://apacheignite.readme.io/v2.3/docs/memory-metrics
Note, that memory metrics collection should be enabled per data region.

Hi Denis,
As per your comment, I can see pages*pageSize rising as entries are put into
the cache - but this metric doesn't come down e.g. when new nodes are added
to the cluster. I assume that the pages remain allocated but with a lower
fill factor.
So pages*pageSize gives a misleadingly pessimis
metrics first. Here you can find how:
https://apacheignite.readme.io/docs/memory-metrics
Note, that pages may be not full, will still be included into this metric.

Hi community,I want monitor ignite cluster off heap memory usage. if off heap available memory is less than 1G then alert.
I went through ignite MBean, find ClusterLocalNodeMetricsMXBeanImpl's NonHeapMemoryUsed. The value is too small. I don't think it is. How ca

Hi Shaomin,
1. Yes, this is a per node setting. So if there are two nodes on one box, it's
possible that 20G will be allocated on this box. You should make sure that this
node only, but you
can use IgniteCache.metrics(ClusterGroup) to get aggregated values for a set
of nodes. This is already fixed in master - in 1.6 aggregated metrics will
be returned by default.

Hi
I am trying to use OFFHEAP_TIERED caches, and have this setting for the memory
,
virtual memory is disenabled. I have a couple questions:
1. Does this mean that 10G off-heap memory is allocated for each cache? If I
have two Ignite instances on a single hard node, 20G will be allocated? What
