Hi,
I want to monitor my AEM 6.5 installation by using JMX.
Looking at /system/console/jmx I thought I am able to e.g. read 'DISK_USABLE_SPACE' (and other metrics).
While I can read some values/metrics e.g. this:
java -jar cmdline-jmxclient-0.10.3.jar - localhost:12345 org.apache.jackrabbit.oak:name=SESSION_COUNT,type=Metrics Count
gives:
11/21/2021 13:41:42 +0100 org.archive.jmx.Client Count: 126
But a
java -jar cmdline-jmxclient-0.10.3.jar - localhost:12345 com.adobe.granite:name=DISK_USABLE_SPACE,type=Metrics Value
gives:
11/21/2021 13:56:39 +0100 org.archive.jmx.Client com.adobe.granite:name=DISK_USABLE_SPACE,type=Metrics is not a registered bean
So the question is: How do I acess ALL the metrics I see at /system/console/jmx by using JMX?
Is there an option I have to activate to enable or what is the reason I am not able to read all the values I see?
(Yes the same happens if I use 'jconsole'.)
Best regards,
Paul

When I test with this with a recent local AEM SDK instance, I can see the MBean
com.adobe.granite:name=DISK_USAGE_SPACE,type=Metrics
in jconsole by default, without turning on something special. And that should be the same in AEM 6.5

Can you check with jconsole, if it can display this mbean?
If I start 'jconsole', click at tab 'MBeans', click at 'com.adobe.granite' I only see 'GraniteSystemStats' and 'Repository' below it.
If I am correct I should also be able to see 'Metrics' here, but it is not there!
So I wonder if I have to enable something or (re)start some service for it...

When I do this with a raw/empty 6.5 installation I also see the Metrics.
Because we didn't see them in our current 6.5 installation which is an old CQ 5.X updated over the years we start from scratch:
Export our content / applications, setup a new 6.5 and start to integrate our application/data.
And now I can see the Metrics as expected!
So remember: Always do the export/import way instead of in-place-updating for avoiding such confusion....

I don't think that this has anything to do with the fact, that this is an upgraded version. This Metrics is defined by a code bundle and not configurable, so I really wonder what happened then.

Me too.
Maybe we just didn't look right?!
Maybe our web application firewall or the 'intelligent' router firewall did something very **bleep**?
Don't know. I only see that it is working now.
Sorry for the trouble...
