AnsibleでCisco IOSの情報収集 - snmp_facts

More than 1 year has passed since last update.


背景

AnsibleでCisco IOSの情報収集 - ios_factsの続編。今回はsnmp_factsの記録。Cisco用ではなく汎用モジュールなので、ベンダー意識しなくていい点と、MIB基準(?)で情報取得したい(でもsnmpgetとかしたくない)場合に使えるかも。

※ansible.cfgやinventoryの設定は省略。

※環境はこちらと同じなので省略。


Playbookサンプル - snmp_facts


snmp_facts.yml

---

- hosts: ios
gather_facts: False
connection: local
tasks:
- name: snmp_facts
snmp_facts:
host: '{{ inventory_hostname }}'
version: v2c
community: public
register: snmpfacts_out

- debug: var=snmpfacts_out



実行例

情報量が多くないので、debug出力のみにしたが、ファイルに保存して、ネットワークの全インターフェース調査などを(楽に)行っても良い。


snmp_facts.yml

[vagrant@localhost ansible]$ ansible-playbook snmp_facts.yml

以上です。ちょっと出来ることは少ないかも。お粗末さまでした。
