Hi,
I'm testing out hobbit 4.1.1 for possible migration from big brother (with bbgen). I suspected scalability issues with BB as my rrd graphs were updated intermittently. However, hobbit is exhibiting similar problems. After about 1 hr of restarting hobbit, the rrd graphs stop updating except for the cpu utilization for the hobbit server itself.
The hobbit server is running RedHat Linux AS 3.0. It has 2 x 2.4 GHz Xeon processors and 1GB of memory. About 800 servers are sending updates to the hobbit server. Another 1200 servers are getting remote tests.
Load average has stayed below 1 most of the time. CPU usage has been low with 75% idle. 4 CPUs show up due to hyperthreading and I've noticed that after the restart of hobbit server, hobbitd_rrd process stays on CPU3 with 100% utilization for the one hour that it is busy.
I hope someone can shed some light on this.
Thanks, Naeem
