Service Virtualization

I've searched through help, communities and documentation but I have not come across a good description of how the priority field effects the operation of the monitors.

The default value is medium. At face value I would assume this would allow me to prioritize some monitors ahead of others, but what is the criteria for when this comes into play?  How do I know if a monitor is delayed or bumped due to a priority override?  It appears multiple monitors can run in parallel - Is this true? How many monitors can be scheduled for the same execution time?

I have 20+ monitors set to medium that I need to run as scheduled (every nnn minutes). I see some are not running with the frequency specified.

Any insights or documentation references would be appreciated.

What version of DevTest are you running?

I am going to do some research on this.

Tom,

I am going to open a support case for this.  I will send you an email with the case number.

Tom, 

This is what I found on CVS Priority. 

I have 5 test case I deployed to CVS Monitor. 

3 cases had a Priority of High. 
1 Case had a Priority of Medium 
1 Case had a Priority of Low. 

The 3 high priority test cases all kicked off all at the same time, it is like submitting a Suite and having all your test cases run in parallel. Then the Medium priority kicked off and last the Low priority. 

High is a Priority 1 
Medium High is Priority 2 
Medium is Priority 3 
Medium Low is Priority 4 
Low is Priority 5 

So it looks like all the cases kick off in parallel based on their priority. 

Does this answer your question? 

Somewhat.

Mine are all set to medium.  I figured what’s the difference if all are high vs medium.  I want them all to run as scheduled.  In my case, no one is more important than the other.

What I’m still not clear on is it seems like at times, some aren’t run as per schedule.

If they were all medium, I would expect them to run together.  If one/some couldn’t I’m wonder how I would know there was a decision to defer the run time that was the result of a priority conflict.

Tom,

If you are not getting a monitor to run when it should be, then this seems like a bug.  You want me to open a new case for you?

~Marcy

I have a case open for that part of the issue. Thank you though.

I was just trying to explore the understanding of the priority setting to determine if that could be a factor.  It doesn’t seem to be.

I will say that I think the priority feature is poorly documented.  You did well in explaining and creating a specific test. I think I would summarize as:

The highest priority service(s) will be launched first if multiple cvs are scheduled to run at the same time.

Multiple high can/will be run in parallel at once.

Do the highs need to complete before the mediums will be launched? Or once the highs are off and running, the mediums will be started regardless of the first batch.

As is my case… if there are multiple (30+) cvs flagged as medium but run according to their own schedule. Every 1,3,8,21,44,55….. minites. Does priority ever become a factor?
