Ivan,

 

I guess I was too impatient on this, the limits file is working on the bottom node.  Thanks for all your help!

Hello Brian,

 

I have no idea, what would be the problem on your side for triggering a throughput test with the debug option. Which version of perfSONAR are you running on that host then?

Here is an example of how this works on my side:

 

pscheduler task --debug throughput --source "source-host" --dest "dest-host" --duration PT10S --ip-version 6

In bold is the section you are interested in. If your version of pS does not allow running the command as per the given examples, please update to the latest.

Still in the meantime you can also check the pscheduler logs in: /var/log/pscheduler/pscheduler.log, where you should be able to find the same output, but mixed with logs from other events.

Ivan,

 

I wasn’t able to get a -debug flag to work on the pscheduler task command, the only thing I could find was to do the above pscheduler debug on command.  Otherwise the throughput test went through fine with the default limits file.

 

Thanks.

Hello Brian,

That seems quite strange, but there are more steps to consider…

Now it is time to initiate a throughput test on the CLI with the –debug option.

 

Please provide the output of this command with the missing parameters added

 

pscheduler task –debug throughput –source … --dest

Ivan,

 

Thanks for reminding me about the validate-limits command, I saw the same errors as you did.  I fixed those by changing the classifier like you suggested, in this case to default.  I had the attached limits file as the operational file last night, but bandwidth tests still took place outside of the specified time range.  I’ve changed my backup of the original file to the operational one and renamed mine to testing.  Any other ideas on how I can get throughput testing to be limited to a specific time frame?

 

Thanks!

Hello Brian,

 

There are problems with your limits file.

You should always check the draft limits file before replacing the operational one.

 

So here is the result:

@r72 ~]$ pscheduler validate-limits limits-brian.conf

Unknown classifiers: allowed-tests, throughput-only-at-night

@r72 ~]$

 

 

It appears the syntax of your limits file is correct. But you haven’t declared 2 groups of clients, which are stated in your Applications statements.

In my example I have generalized on use of Classifiers… in your example I see:

 

    "classifiers": [

                {

                    "name": "default",

                    "description": "Everybody",

                    "identifiers": [ "everybody" ]

                },

                {

                    "name": "friendlies",

                    "description": "Identifiers we find friendly",

                    "identifiers": [ "local-interfaces" ]

                },

                {

                    "name": "hostiles",

                    "description": "Identifiers we find unfriendly",

                    "identifiers": [ "hackers", "bogons" ]

                }

    ],

 

 

Meaning you should either use one of those or add specific declarations for the “allowed-tests”, “throughput-only-at-night”

Hey Ivan,

 

I feel like I’m on the cusp of understanding the limits file, thank you for your help!  I’ve attached my limits.conf file where I’ve added 3 items to the bottom of the LIMITS section, and 2 items to the bottom of the APPLICATIONS section.  Would you mind taking a look and letting me know if you see any problems?

 

Thanks.

Hello Brian,

 

As discussed earlier the pScheduler Limit for the “run-schedule” will control or restrict in which times tests can be scheduled.

Now if you would like to specify the type of the test, I would suggest doing that through the directive: test-type http://docs.perfsonar.net/config_pscheduler_limits.html#test-type-check-test-type

Then you combine both Limit directives in an Application in order to achieve the combination of both restrictions.

Say for example if the names of your Limit directives are (please note the name field are identifiers):

  • “throughput-allowed-slot”
  • “throughput-test-type”

Then your pScheduler Limit application should state:

 

{
            "description": "Allow Throughput tests in a certain period of time.... etc",
            "classifier": "allowed-parties-for-throughput",
            "apply": [
                {
                    "require": "all",
                    "limits": [ "throughput-allowed-slot", “throughput-test-type” ]
                }
            ]
        },

Thanks for the breakdown, Ivan.  Is there any way to limit just throughput tests to specific hours though?

 

Thanks!

Hello Brian,

 

The pScheduler Limits directive you refer to is a limiter / blocker for a group of remote systems to prevent them, even deny, execution of the specified tests in the limit directive.

The group of systems would be identified by the Identifier and the Classifier you have assigned with this Limit in an Application.

 

This will lead to runs falling outside the specified criteria being rejected…in other words will turn as “Non-Starters”.

 

Please note that at first the “Non-Starters” will appear as the “conflict” appears. After 24h the Non-Starters will appear as they are being scheduled.

Ivan Garnizov

Hello,

 

I’m using PWA to build latency and throughput tests and they’re showing up in MaDDash, however I’d like to limit the throughput tests to specific hours.  Would I be able to use run-schedule in the limits.conf file to accomplish this?  Or would there be a better way to go about this?

 

Thanks.
