Shredding Extended Event Actions

lovehatedice_v1The other day I wrote about that torrid love/hate relationship DBAs tend to have with working with XML. In that same post, I promised I would have a follow up post about XML in Extended Events.

Well, today I present to you another opportunity for you to renew your love/hate relationship with XML.

In the previous post (which you can read here), I discussed just one facet of shredding the XML related to Extended Events. Today, we have “actions” to discuss. I am not going to get into what an “action” is today. I will save that for a near future post.

For the shredding of the actions, I will use the TreeHuggerCPU Event Session I used in the last article (for the sake of consistency). The session doesn’t necessarily need to be running. I will just pull the actions related to the session from the metadata accessible via the system catalog views.

Should the session be running (and in my case it is for demonstration purposes), I could open the session data and view it as XML and see something like the following:

action_xml

 

I have highlighted two different types of nodes available in the XML data. In the previous article, I discussed the “data” nodes and I have highlighted that in red here. Today, we are talking actions, and those are highlighted in green this time around. It is the “action” nodes that we will be shredding via the following script.

 

With this script, I can either search for all actions tie to an XE Session, for the actions tied to one event within a Single XE Session, for all actions tied to a specific event across multiple sessions, or for all actions that are tied to any event tied to any event session deployed to the server.

Combine this with the previous script and suddenly all of that XML just got several times easier.
