sakura vps : snmpでrubyしてみる

会社の先輩と話していたら、snmpでサーバの情報持ってくると色々楽しくなりそうっていうことで、
とりあえず試験でvpsにいろいろ環境をしてみた。

まず、snmpがわからないので

を参考に確認してみた。

$ sudo yum list snmp

いらっしゃった。

$ ls /usr/bin |grep snmp
net-snmp-create-v3-user
snmpbulkget snmpbulkwalk snmpconf snmpdelta snmpdf snmpget snmpgetnext snmpinform
snmpnetstat snmpset snmpstatus snmptable snmptest snmptranslate snmptrap
snmpusm snmpvacm snmpwalk

とりあえずデータは取れたっぽいですね。
