---------------------------------------
Summary: Cache "list" request to jolokia
Key: ARTEMIS-5633
URL: https://issues.apache.org/jira/browse/ARTEMIS-5633
Project: ActiveMQ Artemis
Issue Type: Improvement
Components: Web Console
Affects Versions: console-1.2.1
Reporter: Gašper Čefarin
Attachments: queue.txt
I'm referring to the request to URL
{code:java}
https://xxx/console/jolokia/?maxDepth=9&maxCollectionSize=50000&ignoreErrors=true&canonicalNaming=false&mimeType=application/json&listCache=true{code}
with the following request body:
{code:java}
{"type":"list"}{code}
and request response (4mb+ in my case) - high level overview:
{code:java}
{
"request": {
"type": "list"
},
"value": {
"cache": {
"java.lang:MemoryManager": {},
"java.lang:MemoryPool": {},
"java.nio:BufferPool": {}
},
"domains": {
"org.apache.activemq.artemis": {},
"java.util.logging": {},
"jdk.management.jfr": {},
"JMImplementation": {},
"java.lang": {},
"com.sun.management": {},
"hawtio": {},
"java.nio": {},
"jolokia": {}
}
},
"status": 200,
"timestamp": 1755862162
}{code}
There's a lot of duplicated info as well. I didn't dig deeper, i'm just
creating this issue for now. There's also a lot of data for every queue,
attached in the queue.txt file. Notice all the descriptions as well.
A more "concise" list of all queues is fetched from jolokia in another request,
which results in only ~14kb of data in my case.
The request can take a long time to be processed and/or downloaded.
I'm not sure where all this info is needed, and if it's needed at all (like
mentioned, I didn't dig deeper).
Also notice the argument inside the url:
{code:java}
listCache=true{code}
Not sure what this does, maybe it caches the response on jolokia side. The
client still downloads all the data though.
