Zabbix 2.x JMX and multiple instances

[Alex_SYB]

Hi

i have 2 java VM running on my server. How can I get monitor both of them with the JMX client

When I go to add in the second item it says the key is already being used ... and I can't anoint it with an index value !

I tried adding [x] on the end but it seems like jmx agent doesn't like it !

I have opened a bug report

https://support.zabbix.com/browse/ZBX-5536

Not sure if it should be a feature request though.

I have asked if we can have something like this

jmx["1","2"][x]

so it extends the current jmx string to include the [x] on the end that will let it be unique. Also i have request if that can be linked to the jmx port interfaces.

so [0] => to the default interfafe
[1] => jmx interface 1
[2] => jmx interface 2

and not adding in [0] would be the same as it is now.

But this is a long term fix. wonder how people handle it right now ?

Yes, this is an issue we ran into as well. I think there's a issue logged out there somewhere where it suggested key uniqueness should be the interface + jmx key. Currently, we're treating each java instance as a separate host, this probably isn't that ideal though. For us we're after application monitoring so we have a lot of items per java instance so this actually helps reduce some of the clutter, then we have a naming convention to link back to the machine level host that the java instance runs on i.e.

Hosts:
RRUPP1 (reports machine level statistics)
RRUPP1-jetty-4500 (reports jetty based application running on port 4500)
RRUPP1-jetty-4600 (reports jetty based application running on port 4600)

This is described as well in the comments of this issue - https://support.zabbix.com/browse/ZBX-3886

Interesting.

The suggestion i got from a developer was to put spaces in key ie between the , and the "

But i think your idea is better ! Maybe harder though to create a full picture cause you have to bring together multiple !hosts! into 1 screen ...

But I might have to investigate more

Thanks

EDIT: read your link... bit of a quandary. I like your idea and I like having my jvm info in one place... For now I am creating multiple entries with spaces in the key name... until that breaks i guess !

JMX Key Name Hack

You guys still using the JMX Key Name hack? Would you recommend I try it until they get this fixed with https://support.zabbix.com/browse/ZBX-3886?
