Hi, Im trying to put together a number of data recorders, to collect raw data from kernel or from applications. Here you can see a basic idea of SDR: http://www.systemdatarecorder.org/recording/recdesign.html http://www.systemdatarecorder.org/recording/recorders.html
Im currently trying to port sysrec, http://www.systemdatarecorder.org/recording/sdr_bin/sysrec to FreeBSD. I would like to understand how CPU Utilization in FreeBSD counts, comparing to Solaris. Currently sysrec records the following metrics: # Utilisation, # CPU # usr + sys time across all CPUs # Memory # free RAM. freemem from availrmem # Disk # %busy. r+w times across all Disks # Network # throughput. r+w bytes across all NICs # # Saturation, # CPU # threads on the run queue # Memory # scan rate of the page scanner # Disk # operations on the wait queue # Network # errors due to buffer saturation # Would be fair to count CPU Util in FreeBSD similar with Solaris, User + System time ? Is there any Perl module or KSTAT functionality which exports these functionalities to userland for simple consumption ?
