[FOUND QUICK FIX] Data Source troubles after 0.8.7a upgrade

[elliott]

Hi I just upgraded this weekend to 0.8.7a from 0.8.6j and for the most part everything is great with the new version.

Today I attempted to add a script/command based graph and for some reason I get the following data source error:

Code: Select all

Line 225 from rrd.php seems to be looping through each rra for the data source and pieces it together each "RRA:" line. For some reason the first RRA line doesn't have a consolidation function.

I've tried a few times to drop and recreate the data source, data template, and graph templates, but each time I get similar results.

Did something change between revisions that I just not picking up on, or maybe something wrong in my environment?

Thanks,

What type of script is it? Got a link to it?

Have you patched cacti?
Do you have the plugin arch installed?

[elliott]

What type of script is it? Got a link to it?

It is a wrapper script for a database query which returns an integer value in the following form:

Code: Select all

rep_time:23

Have you patched cacti?

I am using a vanilla cacti 0.8.7a install. I installed it via gentoo and ran their webapp-config program which does some linking if I understand it correctly. I guess that could have introduced a problem, so I ran a `cmp` on lib/rrd.php versus the same file from the cacti source and they are the same.

Do you have the plugin arch installed?

Nope. I did a quick read up on what that is. Do you recommend it?

I found the issue. It could possibly be a bug, but removing the "half decade" rra from the data template allows the rrd to be created.

What is the protocol for entering a bug report?

half decade? Thats not a standard timespan.

Hello,

You can solve the problem doing the following:
Goto Console-Data Sources-RRAs-Hourly (1 Minute Average)

Make sure you selected at least one consolidation function (AVERAGE/MIN/MAX/LAST.

I think normally AVERAGE/MAX and LAST are selected!

This solves the problem.

[gandalf]

This issue should be solved with 087b. Please verify

[Adwim Kalfsterman]

I'm using 0.8.7b and experienced the problem, so it's not solved in this version!!

Is it possible to post the rrdtool graph from a failing one? Your workaround is ok, but I'd like to really fix the issue.
Reinhard

[Adwim Kalfsterman]

Gandalf,

Please be more specific, because I don't know what you mean.

We you do, I'll send you the information.

Regards,
Adwim

[gandalf]

If possible, revert to the "failing" szenario. Then, visit graph management, select a failing graph and switch to debug. Post the whole rrdtool graph statement. Then, activate the workaround again.
