Hi Ivan,

About the suggested action:

1) psconfig remotes is configured as expected, as we can see bellow:

[root@monipe-to-perfsonar /]# psconfig remote list
=== pScheduler Agent ===
[
   {
      "url" : "http://monipe-central.rnp.br:8000/pub/config/matriz",
      "configure-archives" : true
   }
]

2) About restart the service, as I am running in a container, I could not restart it, as we can see bellow:

[root@monipe-to-perfsonar /]# systemctl status psconfig-pscheduler-agent
Failed to get D-Bus connection: Operation not permitted
[root@monipe-to-perfsonar /]# systemctl restart psconfig-pscheduler-agent
Failed to get D-Bus connection: Operation not permitted
[root@monipe-to-perfsonar /]# systemctl stop psconfig-pscheduler-agent
Failed to get D-Bus connection: Operation not permitted

Is there another way to check? I tried to restart the container with no success.

I wounder if would have a log that would show the problem in setting the hosts as responsible to run the tests and show that in this host would have a mismatch.

Hello Murilo,

Your response does not include confirmation / statements about the suggested actions.

It is not clear now, if the shared results are after a successful restart or not.

The /var/lib/perfsonar/psconfig/psc_tracker will be populated after valid mesh configuration had been identified and parsed by psconfig.

Best regards,

Ivan

Hi list,

I am running in containers both hosts (one that it is working and another that it is not working).

In the broken one, it appears the following lines in the log:

No error message that could tell me what it is wrong. Any clue how to debug it?

When is the moment that the file /var/lib/perfsonar/psconfig/psc_tracker is written?

Hello Murilo,

It may sound strange, but did you restart the “psconfig-pscheduler-agent” service?

Also your prompt looks strange. It appears like you are on a different system running those commands.

Anyway please make sure you have on the problematic host the psconfig remotes configured

psconfig remote list
=== pScheduler Agent ===
[
   {
      "url" : "http://monipe-central.rnp.br:8000/pub/config/matriz",
      "configure-archives" : true
   }
]

and then restart the service.

Please check again the /var/log/perfsonar/psconfig-pscheduler-agent-transactions.log

There should be messages hinting the mesh configuration in question is being checked.

Regards,

Ivan Garnizov

I tried to change the configuration of /etc/perfsonar/psconfig/pscheduler-agent.json adding the attribute pscheduler-assist-server but it didn't help.

On thing that the followoing file /var/lib/perfsonar/psconfig/psc_tracker is empty like it:

{
"archives" : {},
"leads" : {}
}
--

In another host that the scheduling is working, it looks like this:

{
   "archives" : {
      "UmrpleC0xJUosfKOeTb7qw" : "UmrpleC0xJUosfKOeTb7qw",
      "SIFdxrCaheQUgBzXkZY5NA" : "SIFdxrCaheQUgBzXkZY5NA"
   },
   "leads" : {
      "https://monipe-ro-banda.rnp.br/pscheduler" : {
         "success_time" : 1554150625
      },
      "https://monipe-ro-atraso.rnp.br/pscheduler" : {
         "success_time" : 1554121653
      }
   }
}

What is going on with the problem host? Any clue?

Hi Murilo,

Are there any errors present in /var/log/perfsonar/psconfig-pscheduler-agent-transactions.log ?

My similar issue a while back was due to host resolution, which required some “helper” configuration. See

Subject: Re: [perfsonar-user] Tests are not scheduling on pscheduler

Hi list,

I would like to understand how the perfSONAR hosts know when to schedule tasks based on psconfig remote agent.

I am trying to debug a wierd behavior that the host appears on the configuration of PWA and in the following json, but it does not schedule on pscheduler.

[root@monipe-to-perfsonar /]# psconfig remote list
=== pScheduler Agent ===
[
   {
      "url" : "http://monipe-central.rnp.br:8000/pub/config/matriz",
      "configure-archives" : true
   }
]

If I try to troubleshoot the host, it looks it is ok.

[root@monipe-to-perfsonar /]# pscheduler troubleshoot --host monipe-to-atraso.rnp.br
Performing basic troubleshooting of monipe-to-atraso.rnp.br.

monipe-to-atraso.rnp.br:

Checking path MTU... 65520+
Checking for pScheduler... OK.
Checking clock... OK.
Idle test.... 12 seconds.... Checking archiving... OK.

pScheduler appears to be functioning normally.
[root@monipe-to-perfsonar /]# pscheduler troubleshoot --host monipe-to-banda.rnp.br
Performing basic troubleshooting of monipe-to-banda.rnp.br.

monipe-to-banda.rnp.br:

Checking path MTU... 65520+
Checking for pScheduler... OK.
Checking clock... OK.
Idle test.... 13 seconds.... Checking archiving... OK.

pScheduler appears to be functioning normally.

It is resolving the server name:

[root@monipe-to-perfsonar /]# hostname -A
monipe-to-atraso.rnp.br monipe-to-banda.rnp.br monipe-to-perfsonar

What am I missing? Is there a way to troubleshoot it in a better way?

Hi Guys,

It is strange that is is not scheduling.

I am using hostnames to try to schedule. Should it works with hostnames or just IP address?

Some commands below:

[root@monipe-ba-perfsonar tmp]# psconfig remote list
=== pScheduler Agent ===
[
   {
      "url" : "http://monipe-central.rnp.br:8000/pub/config/matriz"
   }
]

[root@monipe-ba-perfsonar tmp]# psconfig pscheduler-tasks
{
"tasks" : []
}

Any help?

I am trying to schedule some tests from the host: monipe-ba-atraso.rnp.br / monipe-ba-banda.rnp.br ( 2 net interfaces in this host, 1 for ping/trace/owamp and 1 for troughput ).

I am getting problems since it does not put on schedule.

I already check this issues:

- Hostname:

If I understand this correctly, you’re trying to troubleshoot from the local host to itself. That will (and did) work fine for the single-host idle tests. Once it tries to do something multi-participant (simplestream, throughput), it’s going to fail because the same machine can’t be both ends of a multi-participant test even if they’re different interfaces. I was able to run tasks to and from that host with no problem, although I did notice that either the system or the network between here and there was a bit sluggish.

localhost and monipe-ba-atraso.rnp.br:

Checking path MTU... 65520+
Checking timekeeping... OK.
Simple stream test... Failed.
Unable to post task: Error while tasking monipe-ba-atraso.rnp.br: Unable to post task to monipe-ba-atraso.rnp.br: Internal problem; see system logs.

Unless there’s some other problem causing that, you should be seeing a message that says “Task already exists. All participants must be on separate systems.” Early versions of pScheduler choked like that, but it was corrected before anything went into production.

Is there anything of interest in the logs on that system?
