Re: How to get the load status of the Ignite cluster

[Vladislav Pyatkov]

Hi,

You can look at the code[1] and get computation of all metrics.
The task use public API, but in particular information about thread pools
available through MBeans

*org.apache:clsLdr=764c12b6,group=Thread Pools,name=GridExecutionExecutor*

I want to know which API of metrics can I use to get the value of "active",
"idle" and "qsize".

Hi,

It is duplicate.
I am given answer in the thread[1].

Hi,

You can use NodeMetric for estimate loading on machine:
o.a.i.cluster.ClusterNode#metrics
See the example[1] in sample project of Ignite or documentation[2].

Additional
You can try to justify loading by configuration tuning:
- Set the property quite small
o.a.i.configuration.CacheConfiguration#setMaxConcurrentAsyncOperations (500
by default)
- Decrease number of threads on public thread pool[3]
