<span style=" font-family:'Courier New'; font-size: 9pt;">Here's my "canned" response.<br>
See: </span><a style=" font-family:'Courier New'; font-size: 9pt;" href="https://github.com/oetiker/SmokePing/issues/11">https://github.com/oetiker/SmokePing/issues/11</a><br>

Smokeping usual faults:<br>
<br>
Graphs are empty!<br>
<br>
These have two root causes:<br>
<br>
1) Data not reaching the RRD [round robin databases]<br>
Run smokeping in debug mode and watch what it says - you'll probably find some good reasons stuff isn't working and be able to fix it yourself.<br>
Like this: smokeping --debug<br>
<br>
2) Data is hitting the RRD's as confirmed by --debug. However, you still get an empty graph from the browser.<br>
<br>
You see: the user smokeping is running as, is writing the data - that's often root or smokeping. However, the thing that's creating the graphs has to read the data - and that's whatever process your web-server is running as. That's often apache or www, httpd or www-data.<br>
---<br>
<br>
tl;dr<br>
<br>
So provided you're sure that the RRD's are getting the data [not in evidence, but I'll assume you know that, at least for now...] is Apache able to get to the RRD's. [Does it have rights?]<br>

<br>
After upgrading my Ubuntu server this morning to 13.10, all of my smokeping graphs are showing up as broken links. The web log on the server show 404 errors:<br>

<span style=" font-family:'calibri'; font-size: 11pt;"> <br>
Is there somewhere I need to adjust a path? It seems like the files are there in <span style=" font-family:'lucida console'; font-size: 9pt;">/usr/share/smokeping/www/images/<br>
<span style=" font-family:'calibri'; font-size: 11pt;"> <br>
I looked in the pathnames file and those paths seem to check out as well:<br>
<br>
<span style=" font-family:'lucida console'; font-size: 9pt;">root@s42090:/usr/share/smokeping/www/images/LIDAR_APs# cat /etc/smokeping/config.d/pathnames<br>
sendmail = /usr/sbin/sendmail<br>
imgcache = /var/cache/smokeping/images<br>
imgurl = ../smokeping/images<br>
datadir = /var/lib/smokeping<br>
piddir = /var/run/smokeping<br>
smokemail = /etc/smokeping/smokemail<br>
tmail = /etc/smokeping/tmail<br>
<span style=" font-family:'calibri'; font-size: 11pt;"> <br>
Thanks in advance.<br>
