Starfive VisonFive2（RISC-V SBC）で遊ぶ – その5 muninで状態監視＆CPUファンが必要

2023/01/11RISC-V, VisionFive-2

VisionFive2を長時間動かしているとCPUが熱くなってこける・動作が遅くなって操作できないという現象がでたので、状態監視＆グラフ化することにしました。

我が家ではmuninを監視ツールとして使ってるので、munin-nodeを入れてサーバーから監視します。
（muninも重たいので、他にいいツールあったら乗り換えたいところです。何が良いんですかね？）
[code lang="shell"]
$ sudo apt install munin-node
（略）
munin-node (2.0.69-1) を設定しています …
Initializing plugins..done.
Created symlink /etc/systemd/system/multi-user.target.wants/munin-node.service → /lib/systemd/system/munin-node.service.
man-db (2.10.2-1) のトリガを処理しています …
libc-bin (2.33-7) のトリガを処理しています …
