Hello All,

mrtg-2.17.2
RRDtool 1.2.12
routers.cgi : Version v2.22

I have a question about cfg's that have more than one type of data in the config file (i.e. Errors, CPU Usage, and Traffic all in one file). For example I have the cfg file below that runs fine and doesn't give me any errors. I created the cfg from an example at http://www.steveshipway.org/software/rrd/doc/EXAMPLES

I believe the data displayed in the graph displays for the one with <H1>="Traffic Analysis for en0". I attached a screenshot of the graph.
Maybe I don't understand correctly but how are all the other sections supposed to be graphed? Or how do I view the others? If anyone could explain how, (I assume it's per "Target[ ]") the data of multiple Interfaces, or multiple "kinds" of data are displayed.

Here is my Config file for what I described above. Also, screenshot of graph is attached. BTW I have a separate config file called global.cfg with all my Global Directives in it.
Code:

The problem is that you only have one Y-axis, one scale, and so one unit type. If your units are different, then it is difficult to put them on the same graph.

You can define a UserDefined graph (see the documentation, or the Linux CPU graph in the example server) to put multiple Targets onto a single graph. This is good, for example, to show the traffic of multiple interfaces on a a single graph.

If you have v2.22 or later of Routers2, and RRDTool 1.3 or later, then you can define a second Y-axis using the ScaleShift directive. This lets you, for example, have a Celsius AND Farenheit axis on a temperature graph, or display temperature and humidity on separate axis of the same graph.

Your example config defines one Userdefined graph, called _Combined, and four regular Targets. The image you postis for mthe last Target.

When you are viewing the Routers2 webpages, you should see five items in the Targets menu, corresponding to the four regular Targets plus the Combined graph (this one will by default have a little cog as the icon).

Hey Steve, thanks for the reply.

Ok well then that would make sense.
But currently we have RRDTool version 1.2.12, so until I have 1.3 or higher I can only graph one data set in a single graph, unless they are the same data type?? (i.e. Incoming and Outgoing Traffic would be ok on one graph).

Is the process of upgrading RRDTool an upgrade process, or do you have to do a "fresh" install with the newer version?
The server that it is running on is OpenSUSE 10.2, and the Software Manager only finds RRDTool Version 1.2.12-13.2, so I assume I'd have to download and install it manually...
Or do you know of any repositories that may contain a newer version?


Thanks Again,
Matt

After looking around for a WHILE trying to upgrade RRDTool, it seems that their are way too many dependencies that are not available for OpenSUSE 10.2...
So for now it seems we may be stuck with our current version of RRDTool, until I can convince them to upgrade from OpenSUSE 10.2 to at least 11.

Thanks again for you help,
Matt

Hey Steve, sorry for the 3rd straight post.
But I just found out what you were talking about where you can see the cfg's other graphs in its "Target" Menu!!!!


Thanks AGAIN,
Matt

If you want to upgrade RRDTool, you can simply compile it yourself from source code, and install to a separate path (eg, /usr/local/rrdtool-1.3 )

Then you can set the libadd directive in the routers2.conf and the MRTG .cfg file to make MRTG and Routers2 use this library instead of the other. Easy to back out as well, then!

Until you can use ScaleShift, which allows you to have a secondary Y-axis, you are limited to a single Y-axis scale and therefore a single ShortLegend (IE, unit name). There is nothing to stop you graphing e.g. temperature and humidity on the same graph, but they will be on the same scale and you will have to omit the units.

Hey Steve, thanks for the reply.

Ok that sounds easy enough to upgrade. I'll give that a try. Thanks again for the info!!

I have one other question if you could help me with?
So I am using the "Grouping" option with Routers2 and one of the groups is for interface errors on all the routers I have (i.e. "ifInErrors" and "ifOutErrors").
My problem is that while I can see that it IS working, collecting the In/Out errors for each interface (I can see this on the individual graphs for each interface). But it isn't showing up on the "main graph", which is I guess is the average of all the interface's errors...?

For example if the router is let's say utilizing 20 of it's interfaces, and interface 5, 10, 20 have error counts of, let's say 100, 1500, and 300 respectively. The "main" graph does not show any data on it at all. Whereas the individual graphs for those 3 interfaces is showing those errors.

Do you think that it could be that the average is just that low, or is something not set correctly in my config file?

Here is a part of the config file for one of the routers with just one of the interfaces. I built it using a template I believe I found in this site, but not positive about that.
Code:
Target[10.5.1.1_2.err]: ifInErrors.2&ifOutErrors.2:communityName@10.5.1.1:
RouterUptime[10.5.1.1_2.err]: communityName@10.5.1.1:
YLegend[10.5.1.1_2.err]: Error Packets
ShortLegend[10.5.1.1_2.err]: /s
Legend1[10.5.1.1_2.err]: Error Packets
Legend2[10.5.1.1_2.err]:
Legend3[10.5.1.1_2.err]: Error Packets
Legend4[10.5.1.1_2.err]:
LegendI[10.5.1.1_2.err]: &nbsp;Inbound Error Packets:&nbsp;
LegendO[10.5.1.1_2.err]: &nbsp;Outbound Error Packets:&nbsp;
MaxBytes[10.5.1.1_2.err]: 1000
Options[10.5.1.1_2.err]: growright, nopercent, gauge
Title[10.5.1.1_2.err]: 10.5.1.1 2 Errors
PageTop[10.5.1.1_2.err]: <H1>10.5.1.1 2</H1>
   <TABLE>
     <TR><TD>System:</TD><TD>10.5.1.1 in </TD></TR>
     <TR><TD>Maintainer:</TD><TD></TD></TR>
     <TR><TD>Description:</TD><TD> In/Out Error counters </TD></TR>
     <TR><TD>Resource:</TD><TD>2</TD></TR>
   </TABLE>


Do you notice anything not right, or something missing? And/Or do you know of a better Template for collecting interface errors?

EDIT: Sorry one more Q... What happens if you have a cfg for interface traffic on a router and at some point more interface's are opened (i.e. interface status changes to "Up")? Will those sections remain commented out in the cfg file still, or will MRTG pick up on it?

Thanks Again for your Help,
Matt

Not sure what you mean by the 'main' graph. If you mean the interface traffic summary graph then this target will not be on it because it only has the traffic! You will need to define your own custom summary graph.

In this definition, should you be using 'gauge'? I thought ifInErrs was a counter.

If you have commented out sections in the cfg file, they will remain commented out no matter what happens to the router. You will need to regenerate the cfgfile by calling cfgmaker again if the router changes configuration.

Hey Steve, thanks for the reply.

Sorry I should have posted back... I got the UsedDefined stuff working great last Friday I believe it was. After working with this the last few weeks I am much more comfortable now with the program, so-much-so that now I'm "trying" (got one working!!) writing my own Perl scripts to complement some of the templates and such (i.e. using a couple different templates, interface & host one's at same time. Otherwise the results were unpredictable)...

But anyway good stuff, thanks for your help!!


Thanks Again,
Matt
