Re: Recovery email sent without failure or recovery log entry

Hello Christos Chatzaras,
you are right, based on your test sample I receive "Resource limit
succeeded" mails only, but no preceding "Resource limit matched" mail.

Based on Monit 5.35.2, "Resource limit matched" mails are sent first and
if the cpu load is below the usage percentage a "Resource limit
succeeded" mail is sent, as expected.

Nice to see your fix,
