Subject: Re: [perfsonar-user] How to let NDT server handle multiple requests simultaneously...

 

Hi,

 

The original NDT developer just informed me that you can do this by adding the “-m” option to your ndt server command. Assuming this is on a toolkit host using the NDT RPM, you can update the existing WEB100SRV_OPTIONS variable to include -m in the file /etc/sysconfig/ndt. Run "/etc/init.d/ndt restart” after the change and you should be able to run multiple tests. 

 

Thanks,

Andy

 

Best regards,

Ivan

Dear Team,

 

If try to run the default NDT Web Tool from multiple sessions its working 1 by 1 there is no muti threading

 

How can i run simultaneous tests on NDT server?

 

Regards,

 

Sultan

Dear Sultan,

 

Here are some references:

“As an alternative, you may decide to separate your measurement hosts and archive host(s). This allows a single “centralized” archive host to store results from multiple measurement hosts. A few use cases where this may be desirable are as follows”

 

The centralized MA is what you are looking for it sounds like. If you're going to be deploying a lot of these, I would suggest looking into the IP based authentication since it allows for a workflow with fewer steps when turning up these smaller devices. The username/API key approach is still perfectly fine as well, there's just another step when setting up the device.

 

How to manage the raspberry pie from central server?

Please clarify your expectations here! We have recently published automation configuration procedure for central management. http://docs.perfsonar.net/multi_puppet_overview.html

I have never worked with the “raspberry pie”, but I doubt you would like to apply Central configuration management on these.

 

The University of Hawaii uses puppet for this.

 

 

What about reporting?

Again depending on the understanding for reporting one has, you could argue about these sources, but:

Reporting through Nagios: https://github.com/perfsonar/nagios/blob/master/README.md

Monitoring through MADDASH: 

http://docs.perfsonar.net/manage_extra_tools.html#maddash

 

 

To add to this, if you have the results being sent to a MA that has the full toolkit installed on it, the results from these tests will show up in the regular test results as if you had configured them there. The MA actually doesn't care what the src/dst was of the tests - it will show everything that it knows about. You can click and get the same graphs as usual.

 

Best regards,

Ivan

Dear Trocha,

 

Thanks a lot for your valuable feedback

 

Please note that I have installed perfsonar toolkit on centos  and testpoint on Rasberry pie2

Do you already have a central measurement archive?

 

See this for MA details:
