perfSONAR User Q&A and Other Discussion

[Jason Zurawski <>]

Takatoshi;

Here is a database dump of your LS:

http://dc211.internet2.edu/cgi-bin/perfAdmin/view.cgi?hls=http://202.180.38.70:9995/perfSONAR_PS/services/hLS

The first section indicates the SNMP has registered, but I am interested 
in the last 3 sections of this web page (scroll to the bottom) - it does 
not appear your hLS has summarized the information set yet.  Some questions:

 1) how long has the hLS been up?
 2) did you set the following value in the configration file (and if so 
what did you set it to):

maintenance_interval    90

 3) Are there any errors in the log indicating that summarization failed?

A quick fix would be to just restart the hLS and see if the data 
summarizes (this would happen almost immediately) but I would like to 
know why it hasn't done so yet.

Thanks;

-jason
