Hi,

as the problem persists and there were no replies to my last message (except for Matthias, thanks), I try again:

Is there any way to synchronize several instances of hobbit client on one machine with delay so that each sends client data to the server at a different point of time so that the server is able to write those data? Starting those instances with delay does help accidently but not always. Any help or ideas are welcome!

Rolf

The details (My old message): we are running 1 to 3 clients on each host, one for $hostname and one for each virtual host defined on the machine in order to get client data like disk, cpu, etc. for $hostname and for each virtual host. Each client is started using $HOBBITCLIENTHOME/bin/hobbitlaunch --config=$HOBBITCLIENTHOME/etc/clientlaunch.${MACHINE}.cfg --log=$HOBBITCLIENTHOME/logs/clientlaunch.${MACHINE}.log --pidfile=$HOBBITCLIENTHOME/logs/clientlaunch.${MACHINE}.pid

Now I have the problem that client data of one or both clients is neglected by the server. In rrd-data.log it shows: 2006-01-18 13:03:40 RRD error updating /pica/ffm/com/sys/hobbit/hobbit/data/rrd/lbscgi2/netstat.rrd from 141.2.164.215: illegal attempt to update using time 1137585820 when last update time is 1137585820 (minimum one second step) In rrd-status.log are similar entries like 2006-01-18 12:48:38 RRD error updating /pica/ffm/com/sys/hobbit/hobbit/data/rrd/lbscgi2/memory.real.rrd from 141.2.164.215: illegal attempt to update using time 1137584918 when last update time is 1137584918 (minimum one second step)

The client data (disk, etc) for both becomes purple in bb.html. Date for both clients is stored (sometimes) correctly: hobbit/hobbit/data/rrd/otter -rw-r--r-- 1 bb prod 19576 Jan 18 12:43 memory.real.rrd hobbit/hobbit/data/rrd/lbscgi2 -rw-r--r-- 1 bb prod 19576 Jan 18 12:58 memory.real.rrd

I tried starting the clients with some seconds difference, that helps for a certain time and then the problem reappears. What can I do?

kind regards Rolf
