perfSONAR User Q&A and Other Discussion

Hi,

This looks like a bug in the RPM not including that script and the files backing it. We are doing a release in the next week with some other bug fixes, we will get this in there. 

Thanks,

Andy

Good Morning,

 

We ran the following command:

 

$ sudo psconfig maddash-grid add --name "LLNL_rtt"  --check-type ps-nagios-rtt --visualization-type ps-graphs  --check-critical-threshold 100 --check-warning-threshold 80

 

Later  we checked the Web UI, now both grids show up, but the rtt grid has an error – “Grid is down”

 

Checked plug-ins:

 

$  psconfig maddash-check-plugins

 

The following pSConfig MaDDash agent check plugins are installed:

 

ps-nagios-rtt

ps-nagios-pathmtu

ps-nagios-owdelay

ps-nagios-retransmits

ps-nagios-ping-loss

ps-nagios-loss

ps-nagios-dns

ps-nagios-http

ps-nagios-traceroute

ps-nagios-pscheduler-raw

ps-nagios-throughput

 

 

As listed in “Potential Solutions” we checked the files in /var/log/maddash and found the following in maddash-server.log:

 

$ tail -f  maddash-server.log

And yes, that file does not exist.

 

Any guidance would be appreciated.

 

Thank you.

Hi,

 

If you want to have a Grid based on RTT then run a command like the following on your MaDDash host: 

 

psconfig maddash-grid add --name llnll_rtt  --check-type ps-nagios-rtt --visualization-type ps-graphs  --check-critical-threshold 100 --check-warning-threshold 50

 

More details on this command can be found here: https://docs.perfsonar.net/psconfig_maddash_agent.html#configuring-grids 

 

You can tweak the warning and critical thresholds to values that make sense. One thing to be conscious of is that RTT will be distance dependent, but the threshold apply to every test in your grid. If you have endpoints of varying distances an alarm on RTT may not be very useful. If they are similarly distance or you just set the thresholds on relatively high values, you may get some benefit, but that’s why such grids are not configured by default.

 

Thanks,

Andy

Good Morning,

 

Currently we’re using MaDDash to display the results of rtt tests.  That works fine and we’re seeing the Packet Loss grid.  What we want to do is display the Packet Loss AND Round Trip Time from the test results. In other words, 2 grids for the same test results – one showing packet loss and another showing round trip times.   I *think* that would be adding multiple grids with the same check type.  How do we do that?

 

Thanks in advance.

 

 

Gianni
