Orion SDK Performance Tips

Interesting question xtraspecialj​! It's actually something I was thinking of doing a post on at some stage (my plan is to do some tests with a few different techniques, and then compare the efficiency of the approaches).

If we consider the 2 approaches below for example, I know the second approach is faster than the first, because whereas the first it's handling them one at a time, in the second SWIS is handling a lot of hte overhead directly. It's not X times faster (because of auditing, etc), but still should be faster than the first. (As in the cmdlets were designed to accept URIs from the pipeline, so should be faster)

1. 1.$uris |foreach { Set-SwisObject $swis $_ -Properties @{UnmanageFrom=$start;UnmanageUntil=$end} }
2. 2.$uris | Set-SwisObject $swis -Properties @{UnmanageFrom=$start;UnmanageUntil=$end}

Same should apply for remove-swisobject. As far as I'm aware C# doesn't have pipleline equivalance, so that's another hurdle to jump

tdanner​ is obviously the guru on this however, I may be wrong on the above.

This is all correct.

If you want to work in C#, you will be targeting the REST API instead of the PowerShell API. They are similar and you can do batch operations that way as well. The REST equivalent to "$uris | Set-SwisObject ..." is a BulkUpdate request. You can see what that looks like on the wiki: https://github.com/solarwinds/OrionSDK/wiki/REST#bulkupdate-request .

Ahh, OK, so I can just send a group of URI's to the verb as long as the same properties and values are being set?  So the script would need to go through, evaluate all of the objects and determine what properties and values need to be set, then group the objects based on this and set them in groups.  OK, so there is no way to pipe a hash table to these verbs with URI's, properties, and values then, correct?  Not without doing a foreach loop, right?

Right - in one operation you can set the same properties and values on a set of objects. If you need to set different values then you will have to use a loop. SWIS doesn't have a way to accept different values for different objects in a single operation.

(A note on terminology: in SWIS we use the term "verb" to refer to things like Orion.AlertActive.Acknowledge or Orion.AgentManagement.Agent.Deploy that are part of the schema.)

xtraspecialj​ key thing I like to remember is that the URI's are kinda the most important thing when using the *-swisobject cmdlets, as they are basically the identifier that the tasks run
