Hi, I am running FreeBSD-10.0-RELEASE on powerpc64 architecture with two G5 CPUs and zfs as root file system (if it has a meaning). The server is running zabbix server with PostgreSQL database and gather metrics from about twenty servers. I am not familiar too much with this arch and I have faced with following issue - I don't see system cache. Neither top utility, nor sysctl shows any cache size. A top utility just doesn't show this option at all and sysctl shows vm.stats.vm.v_cache_count=0. A kernel and a world were built with default configuration because binaries weren't found at the official sites. My knowledge in ppc are weak and probably missed cache it's a feature of this arch. Any attempts to open web interface of zabbix are led to high amount of reading operations. That's why I am worried about memory caching. Can anyone give some explanation of the issue (missed cache) or a link where a can get information for that. Thank you in advance -- С наилучшими пожеланиями, Дмитрий Мостовщиков Email: dmadm2008@gmail.com --- With best regards, Dmitriy Mostovschikov Email: dmadm2008 at gmail dot comhelp
