Namespace stats issue

Tools AMC
1

Hello,

AMC is not working properly for me in some cases (namespace infos are missing) ajax request failes.

http://localhost:8081/aerospike/service/clusters/76642af6-660c-4ce1-a795-78fa9d731637/namespaces/htmlcache?nodes=xxx,xxx,xxx

Heres a stacktrace: (running 3.9.0.3 and AMC 3.6.9)

You have to use the latest amc version, 3.6.10.1

switched over to 3.6.10.1 noticed that its half working…

at least now the dashboard is fully working thanks for that.

But still im unable to see the number of set entries in definitions, any idears for that?

Looks like this is an oversight from a much older change (I would guess 3.6.1) when the format of the set statistics changed to:

$ asinfo -v sets
ns=<namespace>:set=<set>:objects=459398:memory_data_bytes=0:deleting=false:stop-writes-count=0:set-enable-xdr=use-default:disable-eviction=false;

(Notice the removal of Evict HWM count, and the introduction of Disable eviction). We will follow up and address this in the next release. Thanks for reporting on it!

This should be fixed in the latest release (v3.6.11)
