Netdata Cloudでネットワーク上の機器を一元監視できるようにして初めて、エージェントのバージョンアップを促す警告が現れました。 OpenWRT へ入れた 静的ビルド 版や、AlmaLinuxのパッケージ版のNetdata アップデート 手順を確認します。
Netdata Cloudにアップデートを促される
以前、Netdata Cloudでネットワーク上の機器を一元監視できるようにしましたが（これまでのNetdata関連記事はこちら）、
その後のある日より、各ノードへインストールされているエージェントのアップデートを促す警告が、Netdata Cloudに挙がるようになりました。
図1.Netdata Cloudにアップデート警告
導入当時、各ノードへインストールしたNetdataはv1.38、現在リリースされているのはv1.40なので、小数点以下の2世代以上乖離すると警告が出るのでしょう（それでもモニタリングなどこれまで通りに使用可能）。
図2.アップデート警告の詳細
1）NanoPi R2S OpenWRT 21.02 静的ビルド版Netdataの更新
OpenWRTで用意されているパッケージ版Netdataは、Cloud非対応のスタンドアロン版なので、前回Netdata謹製の静的ビルド版をインストールしました。

Netdata公式ドキュメントによると、アップデートもインストール時に使用した kickstart.sh がアップデートも対応してくれそうなので、まずは --dry-run を付けて実行してみます。
なお、OpenWRTのデフォルトシェルはBusyBoxにリンクされた ash で、

root@R2S:~# ls -l /bin/sh lrwxrwxrwx 1 root root 7 Feb 17 2022 /bin/sh -> busybox |
その作法が多少異なるのでダウンロードした kickstart.sh を実行する部分を sh から bash へ変更しました。

途中やや微妙なところもありますが、 --dry-run 外して本実行するとそれ以前にチェクサムエラーで異常終了しました。

こちらは kickstart.sh に再インストールオプションを付与せずとも、自動的にアップデートが正常終了しました（途中、ユーザ名云々の警告は出るものの特に影響は無し）。

このライブラリが収録されているレポジトリ、 edge/main が有効になっていないためでした（netdataパッケージ自身は edge/community に収録されており、こちらは有効な参照先にしています）。早速、レポジトリファイルを修正。

まとめ
以上でNetdata Cloudに登録している全てのノードが、現行版へアップデートされました。
図6.Netdata Cloud全ノード現行版へ更新完了
結論として、アーキテクチャがやや特殊で、カーネルがやや古いNanoPi R2Sが少しイレギュラーでしたが、それ以外は通常のアップデート操作が問題無くエージェントの更新できることが分かりました。
