Hi Patrick, > On an idle dataserver it will forward reporting data every 10 minutes when > configured with xrd.report. Is this period fixed, or will it vary based > on activity in xrootd? It shouldn't. The interval is fixed though high server activity could delay reporting due to thread contention. > Should I expect any substantive differences between data reported by > xrd.report vs. manually polling the dataserver every 10 minutes using the > query command to xrd? No, they use the same code path. > I was experimenting with xrd and discovered one bug. The xrd command is > limited to retrieving 1K of data from a single query. The output of "xrd > dataserver query 1 p" is over 2K when the dataserver defines 9 oss.cache > groups (8 space tokens + public). Yes, I guess another reason to use "report". Plus is easier on the data server because it's one less login to process. Andy
