Hi there

I have setup the monitor kit 1.03 on a windows machine and have started the server (I had to remove the -j option to make the server run).

Now I run the EHCache client program which gives the following exception:

Code:

Exception in thread "CounterManagerImpl Timer" java.lang.NoSuchMethodError: net.sf.ehcache.Ehcache.getStatistics()Lnet/sf/ehcache/Statistics;

How to make this work?

With regards,
Rune

I also meet this problem . I use ehcache 2.7.4 and ehcache-monitor 1.0.3
anyone please help

Bumpin this.

I'm now trying the same with ehcache 2.8.1 and problem persists. Please anyone??

The monitor is not compatible with new versions of ehcache. Nor is it on the roadmap to be worked on.

(I have sent a mail to the docs team to make that more clear on the docs page related to the monitor - it does indicate such now, but in a not entirely clear way).

It has been replaced by the REST agent that is included with ehcache, that can be enabled thus:

<ehcache ... >
...
<managementRESTService enabled="true" bind="<ip_address>:<port>"/>
...
</ehcache>

The new web-based monitoring console, known as TMC (Terracotta Management Console) replaces ehcache monitor. TMC works with both standalone (BigMemory Go) as well as distributed product (BigMemory Max).

Documentation on TMC: http://terracotta.org/documentation/3.7.4/bigmemorygo/operations/tms

90-day free trial for BigMemory Go:

thanks.

So I have to use the paid product to make this work?

This problem must be easy to fix?
