While I love people testing CVS, please check out the following annoucement.

Hmm, I couldn't get it to do much for me yesterday!

Does anyone produce nitely builds that we can all comment on?
Does the CVS version require any sort of bootstrapping?
Where do I send patches/questions (I don't see a Cacti-Dev mailing list)?

I'm more than pleased to test!

Perldork,

There is a known issue with the 0.8.7 snmpV3 that I have open right now. May get time to fix this weekend. So therefore, there is no use testing yet.

Hello to Michigan and Wisconsin (I grew up in Milwaukee).

When this is done, is anyone producing a "nitely build" site where people can check out builds represented on a nitely (say 2am PST) basis? I've found this has helped developers when people say "cacti-20050125 worked, but now it's broken with cacti-20050126".

I might have some spare CPU cycles to help out with this!

We turned off nightly builds, because we have major changes being added to cacti in this month and next.

What is broken today, might not be broken next week, but might be broken or non existing the following week..

That makes sense, I totally understand that. BUT...with that in mind (:)) how can I help test? I'm assuming it's more of a developer communications thing. I would love to be on a mailing list which says "Try now....try now....." so that I can test out the lastest and greatest features, and offer back patches and such.

I'm a developer (more Java than PHP, but I know Perl so PHP is easy enough to pick up), and I would love to contribute.

Another feature I would like to add (perhaps we can start another thread) is to overlap different data soruces between devices. For instance, I want to be able to overlay the Load statistics between all of our machines in a cluster, I don't see a way to do that in 0.8.6, so I'm willing to write something.

Any suggestions? Want me to start a new thread? Is there a different forum I should be bringing this up in.

Basically, SNMPv3 is my motivator, but since I'll be getting that, I feel obligated to give something back.

Thanks guys!

I will talk to the other developers about it.

Concerning the "overlapping", you can do it. You have to make a custom graph that contains all the Datasources and I would suggest either lines or stacking the sources.

That would be a corner case, IMO, and we typically don't like to code a solution in, if one already exists proceeduraly.

Ahhh, there we go. New graph with "None" and "None" and start adding in datasources. Thanks!

That should work!

Yup, fair enough, sounds like it would be a PITA to maintain. The above solution works just fine for me.

I found a misspelling. This diff against CVS. If there is a dev mailing list I should send these to instead, please let me know.

Thanks for the catch. Fixed in CVS.

I'm also having issues with getting Cacti CVS to work on my server.

Missing path_cactilog:

And I'm also getting a error when viewing a host/device:

Notice: Undefined variable: snmp_value in /home/bknitter/public_html/cacti-cvs/lib/snmp.php on line 87

Warning: implode(): Bad arguments. in /home/bknitter/public_html/cacti-cvs/lib/snmp.php on line 87
SNMP error

Does the CVS version require PHP 5? I only have PHP 4 on this machine.

Give me a few to research. I am working through a formatting issue. Will update you soon.

Update CVS and try again. Reinstall. If you have an IM program, it might be easier to communicate.

Also, the builtin SNMPv3 support was rolled into PHP a few releases ago and is totally undocumented. If you are still getting errors after you update CVS, I will be very interested in working things out with you.

I tried you on IM, didn't get a response. I updated my pofile. Feel free to ping me.

It appears that lib/snmp.php (version 1.71) at line 88, $snmp_value is empty now. I figured out what happened, it's checking for the snmp version, and it's not "ucd-snmp" or "net-snmp", mine says "net-snmp-52".

Here's the way I would fix it!
