  • ネットワークのバッファを増やしたほうがいいと Zenoss のページに書いてあったので・・

# vi /etc/sysctl.conf

# increase network send/receive buffer
net.inet.tcp.sendspace=1048576
net.inet.tcp.recvspace=1048576
net.inet.udp.maxdgram=1048576
net.inet.udp.recvspace=1048576
net.local.stream.sendspace=1048576
net.local.stream.recvspace=1048576
net.local.dgram.maxdgram=1048576
net.local.dgram.recvspace=1048576
net.inet.raw.recvspace=1048576
net.inet.raw.maxdgram=1048576

親Jail で、/etc/devfs.rules を作って修正して再起動して
子Jail で snmpd が起動できるようにする(Jail 環境のみ)

  • 親 Jail

# cp /etc/defaults/devfs.rules /etc
# vi /etc/devfs.rules
以下のように変更する

[devfsrules_jail=4]
#add include $devfsrules_hide_all
add include $devfsrules_unhide_basic
add include $devfsrules_unhide_login

再起動後に 子 Jail の変更

# cp /usr/local/share/snmp/snmpd.conf.example /usr/local/share/snmp/snmp.conf
あとは、MYNETWORK を 自分のネットワーク
COMMUNITY をなんかてきとうなの( public はダメだけど public とか )

そして、snmpd を起動


ほかにも、リソース収集をしたいサーバも snmpd をいれていく。
