Global Environment Vars Shared Between Scripts?

[_dave_b]

Hello. Is there a way to set a global environment variable in Splunk so that it can be shared and used multiple times between scripts?

Specifically, I want to set the version number in my app.conf to a value, then re-use that value later on in the dashboard/XML page for the app.

So my app.conf would look like

[launcher]
version=[VERSION_NUM]

And the footer of my dashboard.js/xml would look like
< Dave B's App Version > < [VERSION_NUM] >

And VERSION_NUM gets defined in some other, external config file

So basically I want to be able to set VERSION_NUM once, and use it repeatedly and consistently.
A little preliminary research reveals that maybe it can be done with REST. Is there a faster way?

Thanks!

Hi _dave_b,

the easiest way to use the app version number from app.conf is to call it from the REST endpoint:

| rest /servicesNS/-/-/apps/local/ | search title="YourAppNameHere" | table title version

and use the result in your footer.

Hope this helps ...

cheers, MuS

Thanks MuS. That helps by pointing me towards REST, but I don't see a section in the REST API Reference Manual that shows me how to access the contents of app.conf

Well, this is because you're looking only at the Search Reference of the command rest but not the REST API Reference Manual and within there this is the important topic for you http://docs.splunk.com/Documentation/Splunk/6.0.3/RESTAPI/RESTapps#apps.2Flocal

cheers, MuS

Ok! Thanks to your help, I am now able to pull the Version number straight from the app.conf file.

Now my quandry is how do I move that number from the Splunk results table that it's in into a line of html on my dashboard?
