Redhat 9 & 0.8.6g

[Instigater]

I wanted to upgrade to newer version of cacti but strange error arised.
I installed new version along with old one using new install and new database.
I can make ucd/net SNMP cpu usage graphs but no data returned for interface and partition statistics.
Right now a cannot play much around because old version (0.8.5) is still needed with its history.

In our test environmet I use Gentoo. On that box everything was normal and working fine except Unix - Get Mounted Partitions which give 0 results.

System:
Redhat 9
PHP Version 4.2.2
UCD-SNMP Version: 5.0.6 (enabled in PHP)

Got this working.
Replaced snmp.php from version 0.8.6c and now SNMP queries work.

I'm rather sure that this is a bug.

Need additional information: snmp version, php_snmp in use, net/ucd snmp version in use, etc.

How do I get all information you need?

[TheWitness]

snmp version run "snmpwalk"

php version run "php -v"

php_snmp in use run "php -m"

Settings->Paths, Settings->General for associations with Net-SNMP versions and binary paths.

I believe that this is impossible while not having Xwindow.
Got that!

I don't see how backing off fixed your problem. I am perplexed. What was the hosts SNMP version that you were polling with when you had the problem. I am hoping v2... You may have to upgrade PHP...

TheWitness

[Instigater]

It was v2.

Right now this is not a problem any more. We did setup new cacti version on another server with Gentoo because old box could not handle two pollers using 1 minute resolution for up to 1 month scale.

We have also hacked cacti to have more functionality - added reports and messages tab (no related to graphs nor querries). This hack only shares web interface between cacti and report system. Reports are PDF files that are shared through web interface. MySQL have reports table where are defined which file is assigned to which user. Messages are just plain text notes what has happened if something abnormal in graphs are shown. They are stored in messages table in SQL.

Is it possible to review and maybe add this functionality in mainstream cacti releases? (I can share source code if needed).

[TheWitness]

With a V2 host I can see why. Upgrading PHP would definately solve a lot of problems there. With regard to your feature, PM me some screen shots and I will distribute and provide comment.

We have injected some contribs right into the code base without much change. It all depends.

Made topic in right place.
