Hi,

You're missing a Defaults file in the directory or any of the

Disable scaling of y-axis

Hi,

 is it possible to disable the scaling of the y-axis ? I have weather
data with pressure values, which range from 950 to 1050 hPa. The cricket
cgi rescales this to khPa which is wrong, as no one reads these values
this way. Setting si-units only affects the legend, scale = 1,* didn't
help either and setting y-min/max had no effect as-well.

Thanks,
Magnus

rrdgraph has the option "--units-exponent" which effects the scaling
of the y-axis.  You could try adding an option to the target to set
this to zero (disable scaling) and get grapher.cgi to pass it to
RRDs::graph....

Re: Disable scaling of y-axis

Hi Bobb,

 thanks for the hint, that worked somehow. However I had to put

rrd-graph-args = "--units-exponent 0"

into the graph --default-- dictionary. Placing it into the specific
graph directory showed no effect at all. Any ideas how to solve this ?
The documentation does not mention any such limitations.

RE: Disable scaling of y-axis

can't you just set y-max and y-min in the graph entry?

I'm doing the exact same thing.

For me the following works fine:

---snip---
view pressure
        elements="pressure"
        rrd-graph-args = '-X 0 HRULE:1016#0000FF'
---snap---

Looks like you'll have to put this into the view and not into the graph.

The HRULE will add a red line whre meteorologists make the difference
between high and low pressure.

Hope it helps,
Sven

Feature: target tag snmp-query-max / Questions regarding cricket/lib/snmp.pm

Hello!

While integrating an UPS device into Cricket I got SNMP error "tooBig".
The SNMP query seems to fail due to too many values fetched in one 
SNMP call.

Therefore I enhanced cricket/lib/snmp.pm to optionally pull a given
number of values at most. 

Patch attached for the curious. It has just reached a "works for me"
state and it is a patch against snmp.pm from Cricket 1.0.2.  
Don't try try this at home, kids .. er .. use this at work, admins. 

Some questions regarding snmp.pm and this patch:

(1)
What do you think about this feature in general? 
I would like to discuss the design, polish the patch and 
have it integrated upstream sometime.

(2)
snmp.pm groups datasources by SNMP target in %oidsPerSnmp. But as far as 
I understand it currently, snmpFetch() is called once per target and 
therefore there can only be one SNMP target, too. 

Can anyone help and explain snmp.pm or parts of it?

(3) 
My current solution looked like an "obvious" (read: fast and easy) way to
implement this. But now snmp-query-max is a tag of dictionary "target".

This means I have to specify the tag with every target. But the limit
looks like a limitation of the hardware to me, so I would like to specify
the limitation "snmp-query-max" in dictionary target-type instead.
That way I could define a new target like the following lines and Cricket
would know how to handle it.
target funnyThing
	target-type	usvWithQueryMaxSet

I think questions for (3) would be
(3a) What do you think: Where does this tag belong to?
(3b) How does my or your idea fit into the Cricket module design?

Any comments, ideas and questions about this are highly welcome.

  Regards
    Florian

Re: Problem with size of UDP packets sent by cricket

Hello!

Did you try polling different numbers of OIDs at once makes
a difference? You might try snmpget with more and more OIDs in one run
instead of snmpwalk.  IMHO snmpwalk does not fetch all OIDs at once.

But coming to your specific question:

See my mail from today:

Subject: [cricket-users] Feature: target tag snmp-query-max / Questions regarding cricket/lib/snmp.pm

Using the new tag snmp-query-max you would be able to query a given
number of OIDs at most. Even only one.
