perfSONAR User Q&A and Other Discussion

[Pedro Henrique Diniz Da Silva <>]

Brian,

Yesterday night everything was working fine. I couldn't find the reasons why the service was not working but i restarted the services and everything is working fine now (http://ps02.cat.cbpf.br/toolkit).

We (CBPF) participate on the WLCG project and i'm trying to fine tune the PerfSONAR servers. There were some other tests being done, but to me to focus on the graphs problems i disabled them. Now we are just using the mesh configuration file from WLCG (https://grid-deployment.web.cern.ch/grid-deployment/wlcg-ops/perfsonar/conf/central/testdefs/jsons/tests-wlcg-all.json).

Actually we are having three problems related to the Throughput Graphs. They are:

* Besides a Test Member is configured by the mesh configuration file, we cannot see this member in the Throughput/Latency Graphs List (https://ps02.cat.cbpf.br/serviceTest/psGraph.cgi). For example, perfsonar-ps.cern.ch is a "BWCTL Test Between WLCG Bandwidth Host" but it doens't appear to me on http://ps02.cat.cbpf.br/serviceTest/psGraph.cgi

* Some members don't exhibit any data on the graphs. For example: https://ps02.cat.cbpf.br/serviceTest/graphWidget.cgi?source=152.84.101.142&dest=90.147.67.253&url="http%3A%2F%2Flocalhost%2Fesmond%2Fperfsonar%2Farchive%2F#

* For some members i have the same problem that i tried to explain on the last e-mail. For some graphs we have the error message: ERROR: No data to plot for the hosts and time range selected. For example: https://ps02.cat.cbpf.br/serviceTest/graphWidget.cgi?source=143.107.129.136&dest=152.84.101.142&url="http%3A%2F%2Flocalhost%2Fesmond%2Fperfsonar%2Farchive%2Fhttps://ps02.cat.cbpf.br/serviceTest/graphWidget.cgi?source=143.107.129.136&dest=152.84.101.142&url="http%3A%2F%2Flocalhost%2Fesmond%2Fperfsonar%2Farchive%2F

Could you help me to solve these problems?

Thanks,

Pedro Diniz

Subject: Re: [perfsonar-user] Throughput / Latency Graphs Not Working - No data to plot

Looking your nodes home page (http://ps02.cat.cbpf.br/toolkit/), it shows that bwctld is not running.

Try running /etc/init.d/bwctld restart, and look at the log files for any errors.

Also, I see that the host is not globally registered. You might want to verify that the port for the Lookup Server (port 8090 and 8096)) are not blocked.

Dears,

I'm a new user of PerfSONAR and i'm having problems to see Throughput / Latency Graphs.

I configured everything following the PerfSONAR tutorial, but some of the graphs are not working. The error message that appears on my browser is: ERROR: No data to plot for the hosts and time range selected.

An example of this error: http://ps02.cat.cbpf.br/serviceTest/graphWidget.cgi?source=152.84.101.142&dest=149.165.225.4&url="http%3A%2F%2Flocalhost%2Fesmond%2Fperfsonar%2Farchive%2F

Does anyone have any idea? Is there any other information that could help on the troubleshooting?

Thanks,

Pedro Diniz
