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=3D0. 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 --=20 =D0=A1 =D0=BD=D0=B0=D0=B8=D0=BB=D1=83=D1=87=D1=88=D0=B8=D0=BC=D0=B8 =D0=BF= =D0=BE=D0=B6=D0=B5=D0=BB=D0=B0=D0=BD=D0=B8=D1=8F=D0=BC=D0=B8, =D0=94=D0=BC=D0=B8=D1=82=D1=80=D0=B8=D0=B9 =D0=9C=D0=BE=D1=81=D1=82=D0=BE= =D0=B2=D1=89=D0=B8=D0=BA=D0=BE=D0=B2 Email: dmadm2008@gmail.com --- With best regards, Dmitriy Mostovschikov Email: dmadm2008 at gmail dot com
