</head>
<body>
<span style=" font-family:'Courier New'; font-size: 9pt;">This is an awesome idea - and one I've wished for in the past - but never got around to working on.<br>
Checking the slave data files modification times seems plausible as a way to check updates - but you'd have to test to be sure. [IIRC that will work though.]<br>
<br>
Personally, I'd probably try to write it in bash - or something completely external to smokeping. [Bash because of few dependicies - though you'll probably want/need something like sendemail for email notifications...<br>
<br>
If slaves are behind NAT or something similar, you'll have to have a way to get to the slave for handling a restart, but that's really outside the scope of what you're doing. <br>
<br>
Honestly, simply getting notification that a slave is not pushing updates would be more than enough - even without the restart.<br>
<br>
Sounds fab to me. And I can't think of a better way, off hand.<br>

<td><span style=" font-family:'courier new'; font-size: 9pt;">Hello,<br>
<br>
I have a Debian Jessie box with Smokeping 2.6 installed on it.<br>
<br>
It receives data from Slaves over the Internet (10 slaves or so).<br>
Each Slave roughly monitors xDSL or fiber links.<br>
<br>
Every monday, I can see that data from one or two slaves is missing.<br>
Then I remotely restart smokeping service on slave where data is missing.<br>
<br>
I would like to implement something like:<br>
<br>
- if no data at all from Slave for a given period of time, then restart Slave's smokeping service and send a Notice email<br>
<br>
- if no data at all from Slave for a longer period of time and Slave's restart already attempted, then send a Warning email<br>
<br>
As Slaves data is stored on a known directory ins Master's filesystem, I think I can detect when data from a slave has not been lately modified, reading directories of files modification times.<br>
<br>
Is there a better way to do so ? Alert's settings seem more appropriate when WAN links in my case, are slower.<br>
<br>
Best regards</td>
