Everything's fine so far, and I am very impressed with how easy it is to collect high-frequency samples with very low CPU usage.<br>
<br>
I've enabled the CPU plugin and the metrics are showing up in Graphite. But each individual metric is prefixed with "cpu-":<br>
<br>
collectdlocalhostcollectd/<br>
├── cpu-0<br>
│ ├── cpu-idle.wsp<br>
│ ├── cpu-interrupt.wsp<br>
│ ├── cpu-nice.wsp<br>
│ ├── cpu-softirq.wsp<br>
│ ├── cpu-steal.wsp<br>
│ ├── cpu-system.wsp<br>
│ ├── cpu-user.wsp<br>
│ └── cpu-wait.wsp<br>
<br>
This seems redundant, and when visualized with Grafana, it takes too much space in the legend. Is there a way to get rid of the "cpu-" prefix in the metrics names? Let's say for the user metric, I want the path to be...<br>
<br>
host.cpu-0.user<br>
<br>
...instead of...<br>
<br>
host.cpu-0.cpu-user<br>
<br>
Same question for the memory plugin.<br>
<br>
For the load plugin, the path is load.load.longterm - here the load label appears on two different levels. Can I get rid of one level?<br>
<br>
Also, is there a way to group some plugins under the same branch? I'd like CPU, memory, load, etc to fall under the category "os". Other plugins, such as Apache, etc. I'd like to group under the "app" category.<br>
<br>
host<br>
os<br>
cpu<br>
memory<br>
load<br>
app<br>
apache<br>
<br>
It's not clear to me how to manipulate these paths with collectd.<span><font color="#888888"><br></font></span></blockquote><div><br><br></div></div></div><div>I don't think there is a simple way to manipulate the paths for every plugin (other than toggling SeparateInstances) to your liking; more to the point, since you are using graphite, I don't think you need to. You could use carbon's rewrite rules feature to force the metrics into the paths of your choosing - great example of rules for doing exactly some of what you are asking for here:<br><br><a href="https://github.com/indygreg/collectd-carbon/blob/master/examples/carbon.rewrite-rules.conf" target="_blank">https://github.com/indygreg/collectd-carbon/blob/master/examples/carbon.rewrite-rules.conf</a><br><br>cheers,<br><br></div><div>-tt<br></div><span class=""><br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><span><font color="#888888">
