はじめに

検証でNW機器を相手にしているネットワークエンジニアにとって、対象機器のログ取得は兎にも角にもまず必要になるものです。
さらに検証環境の規模が大きく対象ノードが多かったり、取得するコマンド群を反復的に取得する場合、ツールで取得することが多いかと思います。
業務ではいまだにTeratermマクロを利用して取得しているところもありますが、個人的に別のツールで取得してみたいと考えてます。
ゆくゆくはログ取得だけではなく、ログ取得以外の機能にも対応できるようにIT自動化ツールであるAnsibleを触ってみたいと思います。
本記事では自動化の一歩として、まずはTeratermで行っているログ取得をAnsibleに置き換えてみたいと思います。

実現したいこと

ios, iosxr, nxosとOSが異なる機器に対してshowコマンドを取得し、ログを保存
取得するコマンドはOSごとにグループを作り、グループ内でも役割ごと（L3orL2など）でコマンド群を分ける
取得したいコマンドはグループごとにテキストのファイルに記載
コマンド群はshowコマンドとrouteコマンドに分ける
ログはプレイブック実行タイミングのフォルダを作成し、その中にホスト単位とコマンド単位のファイルに保存
プレイブックはインベントリに存在しないOSがあっても動作するように汎用的に作る

使用するファイル

使用するファイルが多いので、githubにあげました。
特にsandboxは時間制限があるので、ラボの起動後、すぐにgit cloneでファイルが利用できるのが便利です。
下記のリポジトリをフォークして、クローンしてもらえればすぐにファイルが手元のサーバへ同期できます。

とはいえ、公開用のリポジトリは初めての作成で使い方があまりわかってないので、何かあればコメントいただけると幸いです。

環境

Ciscoのsandbox Labsを利用します。
CML2が利用でき、トポロジーも最初から組まれているCisco Modeling Labs内の、「Multi Platform Network」を利用します。
予約する際、デフォルトでは２時間利用できますが、足りない場合は上限の４時間まで使うように設定を変えることができます。

ラボの全体図

CML2サーバとAnsibleが利用できるDevboxのサーバは別々のノードですが、マネジメントNW経由でCML2内のノードへアクセスできるようになってます。

トポロジー

ターゲットノードのトポロジーと接続情報です。

Ansibleバージョン

初期の状態では２系と古いので、３系にアップグレードします。

ansible 2.9.4
  config file = /home/developer/health-check_common/health_check/ansible.cfg
  configured module search path = [u'/home/developer/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/site-packages/ansible
  executable location = /usr/bin/ansible
  python version = 2.7.5 (default, Aug  7 2019, 00:51:29) [GCC 4.8.5 20150623 (Red Hat 4.8.5-39)]

事前準備

今回使用するplaybookではios_command、iosxr_command、nxos_commandのモジュールを利用します。
接続方法としてparamikoを利用するため、paramikoのインストールとSSHの追加設定を行います。

Devnetサーバにて

初期の状態ではAnsibleのバージョンが2系なので、３系にアップグレードします。

リポジトリのクローン

上記のリポジトリをクローンし、プレイブックがある階層へ移動します。

$ git clone http:XXXXXX.git
$ ls
$ cd cd log_get/health_check/

セットアップshellの実行

ここではAnsibleの３系へのアップグレードとgit configの設定を行なってます。
一部この記事には必要のないntc-templateのインストールも行ってますがお気にせず。

setup.sh

sudo yum install -y python36 python36-pip python36-devel
sudo pip-3.6 install --upgrade pip
pip uninstall ansible
pip3 install ansible
pip3 install ntc-templates
pip install --upgrade pip
ansible --version
git config --global user.email "hogehoge@example.com"
git config --global user.name "hogehoge"

git configを修正したい場合は任意で変更ください。
問題なければシェルを実行します。

$ ./setup.sh

実行後、Ansibleのバージョンが3系になっていればOKです。
バージョンに関するワーニングが出てますが、ログの取得には影響なしです。

[DEPRECATION WARNING]: Ansible will require Python 3.8 or newer on the controller starting with Ansible 2.12. Current

  libyaml = True

CML2サーバにて

CML2へアクセスし、Multi Platform Networkのラボ内のedge-sw01へコンソールアクセスします。

ssh用の設定を追加します。(参考)

対象: edge-sw01

conf t
ip domain-name cisco.com
ip ssh  version 2
username cisco privilege 15 password cisco
line vty 0 4 
login local
crypto key generate rsa (768bit以上)

対象: core-rtr01/02

crypto key generate rsa
conf t
ipv4 access-list PERMIT-SSH 10 permit ipv4 10.10.20.0 0.0.0.255 any
ssh server vrf Mgmt-intf ipv4 access-list PERMIT-SSH

　Ansibleの設定

ansible設定ファイルの作成

初めてSSH接続する場合など、警告によりplaybookが中断してしまうのを防ぐため、設定ファイルに下記を記載しておきます。(参考)

ansible.cfg

[defaults]
host_key_checking = False

[ssh_connection]
ssh_args = -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null

inventoryの作成

今回はインベントリーファイルにホストの情報と変数を記載します。
IOS種別でまとめ上げ、さらに役割でまとめます。

親グループ	子グループ	孫グループ	ホスト
ios	l2	-	edge-sw01
ios	xe	dist	dist-rtr01/02
ios	xe	internet	internet-rtr01
iosxr	-	-	core-rtr01/02
nxos	-	-	dist-sw01/02

変数

共通

ログイン情報は全てのホストで共通のため、[all:vars]でまとめてしまいます。
また、接続方法はOSごとに使用するモジュールを使い分けるため、ansible_connection=network_cliとしています。
OSの種類は各グループ変数内で定義します。

グループ変数

また、取得するコマンドは各グループごとにコンフィグとステータス確認用のshow系と経路確認用の２つにリストを分けてます。
それぞれ変数にして、プレイブックから呼び出して使用します。

commands_show: GROUPNAME_show.txt
commands_route: GROUPNAME_route.txt

プレイブック

inventoryに記載された3種類のOSへ１つのプレイブックでログを取得したいと思います。
ただし、実際にコマンドを取得するタスクはOSごとに異なるモジュールを使用するため、ロールとしてタスクを分けて、
メインのプレイブック(log_get.yml)からロールを呼び出す形にしたいと思います。

タスクステップ概要

#	タスク	記載場所
1	実行時間の変数作成	log_get.yml
2	ログ保存ディレクトリの変数作成	log_get.yml
3	ログ保存ディレクトリ作成	log_get.yml
4	ios用コマンド取得	get_ios_command/tasks/main.yml
5	ios用コマンド保存	save_cisco_command/tasks/main.yml
6	iosxr用コマンド取得	get_iosxr_command/tasks/main.yml
7	iosxr用コマンド保存	save_cisco_command/tasks/main.yml
8	nxos用コマンド取得	get_ios_command/tasks/main.yml
9	nxos用コマンド保存	save_cisco_command/tasks/main.yml

プレイブック内容

log_get.yml

---
- hosts: all     # (1)
  gather_facts: false
  tasks:
    - name: create time # ログ保存日時変数作成
      set_fact:
        exe_date: "{{ lookup('pipe', 'date +%Y%m%d_%H%M_%S') }}"
      run_once: true     # (2) 

    - name: create parent directory
      set_fact:
        logdir_date: "{{ inventory_dir }}/log/log_{{ exe_date }}"
      run_once: true

    - name: create directory for log      # ログ保存用実行日時ディレクトリ作成
      file:
        path: "{{ logdir_date }}/"
        state: directory
      register: logdir
      delegate_to: localhost      # (3)
      run_once: true

- name: ios section
  hosts: ios
  gather_facts: false
  roles:
    - { role: get_ios_command, when: "'ios' in groups and inventory_hostname in groups['ios']" }     # (4)
    - { role: save_cisco_command_logdir, when: "'ios' in groups and inventory_hostname in groups['ios']" }

- name: iosxr section
  hosts: iosxr
  gather_facts: false
  roles:
    - { role: get_iosxr_command, when: "'iosxr' in groups and inventory_hostname in groups['iosxr']" }
    - { role: save_cisco_command_logdir, when: "'iosxr' in groups and inventory_hostname in groups['iosxr']" }

- name: nxos section
  hosts: nxos
  gather_facts: false
  roles:
    - { role: get_nxos_command, when: "'nxos' in groups and inventory_hostname in groups['nxos']" }
    - { role: save_cisco_command_logdir, when: "'nxos' in groups and inventory_hostname in groups['nxos']" }

解説

(1)

- hosts: all     # (1)

前半のロールを呼び出す部分はhostsに全ての対象を指定しています。
これにより作成した変数(ログ保存日時や保存用のディレクトリなど)が全てのホストで利用できます。
仮に特定の対象のみhostsの対象とした場合、定義されていないホストでは変数がundifinedとなり
、変数の利用ができなくなります。

(2)

      run_once: true     # (2)

run_onceは１度のみ実行する場合に設定します。
hostsはallになってますが、全てのホストで実行されてしまうと、ホストごとにバラバラの日時情報が変数に定義されてしまうことになるため、
この設定で１度のみ実行した日時情報を全てのホストで利用するようにします。

(3)

      delegate_to: localhost      # (3)

delegate_toは指定された対象にだけ実行させる設定です。
実際にログ保存ディレクトリを作成するのはAnsibleサーバであるコントロールノード内のディレクトリのため、
localhostにすることで、Ansibleサーバ自身へディレクトリを作成します。
これがないと、各ターゲットノードにディレクトリを作成しようとしてしまいます。
また、ここでもrun_onceを設定し、localhostのみの実行としています。

(4)

  roles:
    - { role: get_ios_command, when: "'ios' in groups and inventory_hostname in groups['ios']" }     # (4)

各OSごとに取得用のタスクをrolesディレクティブで呼び出します。
今回のプレイブックは汎用的に使用することも考慮して、環境によっては存在しないOSがあっても動作するように作っています。
もしインベントリーファイルに定義されないOSがあっても使用するプレイブックは変更しなくても良いように
whenを使いグループの定義とそのグループ内のホストが定義されているときのみロールを呼び出すようにしています。

ロール

プレイブックから呼び出されるタスクを定義した各ロールです。
今回は取得用は各OSごとにタスクが分かれてますが、保存用のタスクはciscoとして共通で１つのロールを使い回してます。
取得用はOSごとに分かれてるとは言っても、異なる部分は使用するモジュールのみで、大きな違いはありません。

ios用取得タスク

取得用のコマンドリストファイルを読み込み各行をリストに格納し、
ループで読み込んだリスト全てをcommandsのitemに代入しています。

また、取得結果はset_factで変数化して、別のロールでも使用できるようにしています。
これをshowコマンド用と経路コマンド用とで実施します。

roles/get_ios_command/tasks/main.yml

---
- name: get ios_command_show
  ios_command:
    commands: "{{ item }}"
  register: show_result
  loop: "{{ lookup('file', 'files/{{ commands_show }}').splitlines() }}"

- name: set show results
  set_fact:
    show_results: "{{ show_result.results }}"

- name: get ios_command_route
  ios_command:
    commands: "{{ item }}"
  register: route_result
  loop: "{{ lookup('file', 'files/{{ commands_route }}').splitlines() }}"

- name: set route results
  set_fact:
    route_results: "{{ route_result.results }}"

iosxr用取得タスク

roles/get_iosxr_command/tasks/main.yml

---
- name: get iosxr_command_show
  iosxr_command:
    commands: "{{ item }}"
  register: show_result
  loop: "{{ lookup('file', 'files/{{ commands_show }}').splitlines() }}"

- name: set show results
  set_fact:
    show_results: "{{ show_result.results }}"

- name: get iosxr_command_route
  iosxr_command:
    commands: "{{ item }}"
  register: route_result
  loop: "{{ lookup('file', 'files/{{ commands_route }}').splitlines() }}"

- name: set route results
  set_fact:
    route_results: "{{ route_result.results }}"

nxos用取得タスク

roles/get_nxos_command/tasks/main.yml

---
- name: get nxos_command_show
  nxos_command:
    commands: "{{ item }}"
  register: show_result
  loop: "{{ lookup('file', 'files/{{ commands_show }}').splitlines() }}"

- name: set show results
  set_fact:
    show_results: "{{ show_result.results }}"

- name: get iosxr_command_route
  nxos_command:
    commands: "{{ item }}"
  register: route_result
  loop: "{{ lookup('file', 'files/{{ commands_route }}').splitlines() }}"

- name: set route results
  set_fact:
    route_results: "{{ route_result.results }}"

cisco用保存タスク

Ansible実践ガイドを流用しました。
取得結果をコマンドごとに保存するパートと、ホスト単位でshowコマンド全て、経路コマンド全てを保存するタスクとなってます。

---
- name: save show per commands
  copy:
    content: "{{ item.stdout[0] }}"
    dest: "{{ logdir.path }}/{{ inventory_hostname }}_{{ item.item | replace(' ', '_') }}.log"
  loop: "{{ show_results }}"
  loop_control:
    label: "{{ item.item }}"

- name: save route per commands
  copy:
    content: "{{ item.stdout[0] }}"
    dest: "{{ logdir.path }}/{{ inventory_hostname }}_{{ item.item | replace(' ', '_') }}.log"
  loop: "{{ route_results }}"
  loop_control:
    label: "{{ item.item }}"

- name: save show per hosts
  blockinfile:
    block: "{{ item.stdout[0] }}"
    path: "{{ logdir.path }}/{{ inventory_hostname }}_show.log"
    marker: "======================  {{ item.item }} ======================="
    create: yes
  loop: "{{ show_results }}"
  loop_control:
    label: "{{ item.item }}"


- name: save route per hosts
  blockinfile:
    block: "{{ item.stdout[0] }}"
    path: "{{ logdir.path }}/{{ inventory_hostname }}_route.log"
    marker: "======================  {{ item.item }} ======================="
    create: yes
  loop: "{{ route_results }}"
  loop_control:
    label: "{{ item.item }}"

実行結果

出力が多いので結果は省きます。。
取得と保存は問題なく実行できました。
各機器に初めて接続する際に、タイムアウトで最初のコマンドが取得できない場合がたまにあります。
その場合はもう一度プレイブックを実行すれば取得できますので、エラーが出たらやり直してください。

問題なし。

さいごに

取得したいコマンドをテキストファイルに記載して、無事にログを取得することができました。
これでプレイブックや変数ファイルをいじることなく、取得したいコマンドのリストファイルだけの更新でコマンドの増減に対応できると思います。
気になることといえば、コマンドを実行したコマンドプロンプトを含む行が結果に記載されないため、
コマンドだけのログを見たときに、本当にファイル名と同じ結果なのか？とか、みている結果はどのノードのだっけ？とかちょっと迷ったりするのかな、と思いました。
(show runとかはhostnameがあるので判断可能ですね。)

作り込みで確認できれば問題ないですが、後からログだけみたときにどうやってこの対象のログだと証明できるのかなーとか思ったり。
ログはansibleの実行結果を含む形で保存した方が安心なのかなーと心配性な私は思っちゃいました。

今後は、ログをパースするためのプレイブックを作ったり、jinja2のtemplateファイルを利用した変数ファイル自動生成にチャレンジしたいと思います。
