Hi Henrik,

Thanks, it works .. maybe it will be more comprehensive and impressive if it will give graphical I/O stat per filesystem ?

Re: Disk I/O check for Linux


Hi,

the Hobbit mailing list - user-ae9b8668bcde@xymon.invalid - really is the best place for
support questions.

The only I/O measurement built into Hobbit is the data collected from
"vmstat", which gives you an overall measure of the amount of time
spent waiting for disk I/O. This graph is not displayed by default; you can make them appear on the "trends" page by adding
   TRENDS:*,vmstat:vmstat1|vmstat5
to each of the host entries in bb-hosts. That will give you a "CPU
utilisation" graph that includes the I/O wait time, and a "Block I/O"
graph showing the number of blocks read from/written to a disk device.


Regards,
Henrik

Hi,
 
I gave this a try and the vmstat items show up only as objects and not
graphs.   Part of the host entry is below for this host.

I am sure I am missing something really easy.   Any ideas?

Sorry for hijacking this thread, but this is *mostly* on-topic.

Is there a way to make the above TRENDS setting for all hosts? I tried looking at hobbitgraph.cfg and hobbitserver.cfg, but could not determine any applicable syntax. 

PS - I like the added graphs.

Thanks for any assistance you can provide.

I'm going to drift the thread into yet another tangent ... I'd like to have the vmstat graph for CPU utlization show up on the cpu column along with load average.  Is that possible?
