[Xymon] rrddefinitons.cfg - how to modify the default step in RRA

[Michael Beatty]

> From the rrddef.cfg comments:
> *# Each section key is the column- or data-name reported from your
> # client test.* Typically this is "cpu", "memory", "tcp", or some
> # custom test you have created.
>
> In your original script:
> [ buda ext]# cat httpd_threads.sh
> #!/bin/bash
> THREADS_HTTP=`ps -ef | grep -c [h]ttpd`
> *LINE="data $MACHINE.trends*
> [httpd_threads.rrd]
> DS:threads:GAUGE:5:U:U $THREADS_HTTP"
> $BB $BBDISP "$LINE"
>
>
> it appears that your  data name is "trends".  This is what xymon is 
> trying to match in rrddef.cvf.  The key you should be using in 
> rrddef.cfg.

> [trends]
>     -s 5

>     RRA:AVERAGE:0.5:360:576
>     RRA:AVERAGE:0.5:1440:576
>     RRA:AVERAGE:0.5:17280:576

> With that said, "trends" is already a column heading... I'm not sure 
> that using it for your rrd key won't cause other problems in xymon.  
> Maybe change it to "httpd_threads"?

> If that doesn't work, try putting the -s in the default section "[]", 
> and see if that works.  You shouldn't leave it there as it will set 
> all future graphs to a 5 second step, but it works there, then you 
> know your problem is with your data name and key.
