linux - 监控配置 |总 CPU |语法错误 |

Question

Monit 的 official documentation状态如下:

# Test CPU usage including user, system and wait. Note that 
# multi-core systems can generate 100% per core
# so total CPU usage can be more than 100%
if cpu usage > 200% for 4 cycles then alert

但是上面给出的语法错误是:

/etc/monit/conf.d/test:61: Error: syntax error 'cpu'

有相同的指示吗？

Answer 1

看来你的 monit 版本低于 5.14，因为这个功能是在这个版本中添加的:

Version 5.14.0

New: Simpler system-wide cpu usage test (total of user%, system%, wait%). Example:

if cpu usage > 99% then alert

此外，我提请您注意以下事实:从 5.16 版开始，多核系统上的总 CPU 使用率计算为 0 到 100 之间的数字，因此您的 200% 值没有理由

You can now check a process' CPU usage in a more natural way as a percentage between 0-100 on a multi-core system. For instance, to check if a single-threaded application like node.js has gotten stuck on 100% CPU,
