【Zabbix 5.0】YAMAHA 製品のトラップ監視をできる環境構築

お疲れ様です。satimoです

今回はヤマハ製品のトラップ監視をZabbixで行う方法についてつらつらと書いていきます。

Zabbixの環境構築やトラップ監視する為の環境構築が済んでいない方はこちらをご参考ください。

ZabbixでSNMP監視を行う為の大まかな流れはこちらになります。

  • snmptt.confの作成
  • トラップ監視用のテンプレート作成

snmptt.confの作成

Zabbixでベンダー(今回はヤマハ)が提供しているトラップを受信して監視を行う為には、提供されているMIBファイルをZabbixが理解できるように変換してあげる必要があります。

初めにヤマハの更新ページからMIBファイルのダウンロードを行います。

ヤマハ製品のプライベートMIBダウンロード先

http://www.rtpro.yamaha.co.jp/RT/docs/mib/index.php

『yamaha-private-mib.tar.gz』をクリックしファイルのダウンロードを行います。

ダウンロードしたファイルををトラップ受信させるサーバへ保存します。

今回は「/usr/share/snmp/mibs/」の下に『yamaha』ディレクトリを作成しその中に保存しています。

保存後、ダウンロードしたファイルを展開しテキストファイルが保存されることを確認します。

# cd /usr/share/snmp/mibs
# mkdir yamaha
# cd yamaha
# tar xzvf yamaha-private-mib.tar.gz
# ls
yamaha-private-mib.tar.gz     yamaha-sw-errdisable.mib.txt
yamaha-product.mib.txt        yamaha-sw-firmware.mib.txt
yamaha-rt-firmware.mib.txt    yamaha-sw-hardware.mib.txt
yamaha-rt-hardware.mib.txt    yamaha-sw-l2ms.mib.txt
yamaha-rt-interfaces.mib.txt  yamaha-sw-loop-detect.mib.txt
yamaha-rt-ip.mib.txt          yamaha-sw-power-ethernet.mib.txt
yamaha-rt-switch.mib.txt      yamaha-sw-rmon.mib.txt
yamaha-rt.mib.txt             yamaha-sw-termmon.mib.txt
yamaha-smi.mib.txt            yamaha-sw.mib.txt
yamaha-sw-bridge.mib.txt

保存したディレクトリのファイルを読み込んであげるおまじないを行います。

# vi /etc/snmp/snmp.conf
mibdirs /usr/share/snmp/mibs:/usr/share/snmp/mibs/yamaha
mibs all

snmpttconvertmibコマンドでダウンロードしたテキストファイルを変換します。

# snmpttconvertmib --in /usr/share/snmp/vendors-mibs/yamaha-product.mib.txt --out snmptt_yamaha-product.conf
# snmpttconvertmib --in /usr/share/snmp/vendors-mibs/yamaha-rt.mib.txt --out snmptt_yamaha-rt.conf
# snmpttconvertmib --in /usr/share/snmp/vendors-mibs/yamaha-rt-firmware.mib.txt --out snmptt_yamaha-rt-firmware.conf
# snmpttconvertmib --in /usr/share/snmp/vendors-mibs/yamaha-rt-hardware.mib.txt --out yamaha-rt-hardware.conf
# snmpttconvertmib --in /usr/share/snmp/vendors-mibs/yamaha-rt-interfaces.mib.txt --out snmptt_yamaha-rt-interfaces.conf

# snmpttconvertmib --in /usr/share/snmp/vendors-mibs/yamaha-smi.mib.txt --out snmptt_yamaha-smi.conf
# snmpttconvertmib --in /usr/share/snmp/vendors-mibs/yamaha-sw.mib.txt --out snmptt_yamaha-sw.conf
# snmpttconvertmib --in /usr/share/snmp/vendors-mibs/yamaha-sw-bridge.mib.txt --out snmptt_yamaha-sw-bridge.conf
# snmpttconvertmib --in /usr/share/snmp/vendors-mibs/yamaha-sw-errdisable.mib.txt --out snmptt_yamaha-sw-errdisable.conf
# snmpttconvertmib --in /usr/share/snmp/vendors-mibs/yamaha-sw-firmware.mib.txt --out snmptt_yamaha-sw-firmware.conf
# snmpttconvertmib --in /usr/share/snmp/vendors-mibs/yamaha-sw-hardware.mib.txt --out snmptt_yamaha-sw-hardware.conf
# snmpttconvertmib --in /usr/share/snmp/vendors-mibs/yamaha-sw-l2ms.mib.txt --out snmptt_yamaha-sw-l2ms.conf
# snmpttconvertmib --in /usr/share/snmp/vendors-mibs/yamaha-sw-loop-detect.mib.txt --out snmptt_yamaha-sw-loop-detect.conf
# snmpttconvertmib --in /usr/share/snmp/vendors-mibs/yamaha-sw-power-ethernet.mib.txt --out snmptt_yamaha-sw-power-ethernet.conf
# snmpttconvertmib --in /usr/share/snmp/vendors-mibs/yamaha-sw-rmon.mib.txt --out snmptt_yamaha-sw-rmon.conf
# snmpttconvertmib --in /usr/share/snmp/vendors-mibs/yamaha-sw-termmon.mib.txt --out snmptt_yamaha-sw-termmon.conf

変換したconfファイルを1つのファイルにまとめてあげます。

# cat *.conf >snmptt_yamaha.conf.org

最後の仕上げで、zabbixがわかるおまじないを行います。

# sed -e "s/^FORMAT\s/FORMAT ZBXTRAP \$aA /g" snmptt_yamaha.conf.org > snmptt_yamaha.conf

作成したsnmptt_yamaha.confファイルを移動してあげます。

# mv snmptt_yamaha.conf /etc/snmp/
# cd /etc/snmp/

# ls
snmpd.conf      snmptt.conf.bak  snmptt_base.conf
snmptrapd.conf  snmptt.ini       snmptt_yamaha.conf

snmptt.iniファイルの編集を行います。

ファイルの一番下に[TrapFiles]の項目があるのでそちらに今回作成したファイルを記載してあげます。

# vi snmptt.ini

・・・

[TrapFiles]
# A list of snmptt.conf files (this is NOT the snmptrapd.conf file).  The COMPLE
TE path
# and filename.  Ex: '/etc/snmp/snmptt.conf'
snmptt_conf_files = <<END
/etc/snmp/snmptt_base.conf
/etc/snmp/snmptt_yamaha.conf
END

ファイルの編集後snmpttサービスの再起動を行います。

# systemctl restart snmptt

FORMAT ZBXTRAP $aA $ar $*

これでZabbixサーバでの作業はおわりです。

動作確認も含めてトラップ受信させてみます。

# snmptrap -v 2c -c public 127.0.0.1  '' .1.3.6.1.4.1.1182.2.4.0.2
# tail /var/log/snmptt/snmptt.log

2020/08/21 00:09:21 .1.3.6.1.4.1.1182.2.4.0.2 Normal "Status Events" 127.0.0.1 - ZBXTRAP 127.0.0.1 This trap signifies that a IP keepalive status is up.

正常にトラップ受信できた場合は/var/log/snmptt/snmptt.logファイルにログが記載されています。

上のように記載されていればOKです

次回はZabbixのコンソールでテンプレートの作成を行っていきます。
