Re: Jenkins doesn't recognize a slave being down

['Renuka Radhakrishnan' via Jenkins Users]

I am facing this same issue as well. I just added a comment to JENKINS-5055.

Re: metrics support? # of failures/successful builds

['Renuka Radhakrishnan' via Jenkins Users]

Hi,

I am using this plugin to get the success% of my jobs. But it does that for 
the entire period. Is there a way to get the results for a specific 
timeline ? For example, I want to know how we did last week.

Thanks,
Renuka.

Not receiving emails from any builds

[Renuka Radhakrishnan]

Hello,

My Jenkins is running in GCE, I have set up email notification through 
SendGrid. Email notifications from builds were working fine until early 
this week. It stopped working after I restarted my Jenkins. Now the test 
email works, but I don't receive any emails from the builds. I am using the 
Extended email notification plugin. Has anyone seen this ? I looked at the 
Jenkins logs and don't see any error there.

Thanks,
Renuka.
