[Agent]Can we config the same agent jar/folder in different applications?

[WangHouLing]

Hi,
I want to run multiple agents on one box from the same skywalking agent installation. There is a problem is agent.application_code in agent.config. Can I config different agent.application_code for same skywalking agent?
I'd appreciate it if you can help me.

What version of sky-walking are you using?

3.2.6

What version of your OS?

windows10

What version of your JRE?

1.8

What company or project?

springboot project

What is your meaning about multi agents in on box? which agents?

And what is the box?

[zone1511]

he means in single os, running multiple application which want to monitor by the skywalking agent. Any way to specify the agent application name from JVM argument instead of reading from agent config.

@wu-sheng I'm sorry to give you a reply so late!
zone1511 has already expressed what I mean :)

The easy answer is YES, you can.

But you should be aware of these:

1. Follow this document(assume you need cn version) : link . You can use -Dskywalking.* to override any config in file as you wish.
2. When two application use the same agent folder, by default, your logs output into the same file. This is hard to read and understand, but these is a bug in this version(3.2.6) to override it. I already try to fix it, see Make sure the log config works. #697.

So, that is why I just recommend use separated agent jars. OK?

BTW, I just change the issue title.

Hope these can help you.

Ok, I see. Thank you!

Hi PMC, So the agent will read the config file related to its absolute location? In this way, we don't need to share one agent per machine and we can have many agent plus config plus log folder so each monitored application. As different agent may need to load different plugin for performance reason. If use same folder for multiple app. It is difficult to manage.
