cacti-user Mailing List for Cacti

Hi All,

First I would like to thank you for this great tool!

Unfortunately I have some problems with my cmd poller.
I am monitoring 30 hosts which are running snmp v3. snmpwalk works just 
perfect for every single host.

Some of my hosts were timing out when polling, but snmpwalk was still fine. 
When using cmd.php manually I observed something strange.

For example if I do cmd.php 3 3 it is fine but cmd.php 3 5 causes host 5 to 
time out...at the same time cmd.php 5 5 is gives me good result.
I avoided this problem with setting Maximum Concurrent Poller Processes to 50 
which is more than number of my hosts...in this case every single call to 
cmd.php polls only one host and all graphs are fine. I have found patch at

http://www.cacti.net/downloads/patches/0.8.6j/snmpwalk_fix.patch

It did not resolve my problems.

I am using NET-SNMP version: 5.3.1
and cacti-0.8.6j

Do you have any ideas or I should report a bug?

I was feeling a bit un-appreciated as a Developer and I thought of all
the other developers of Open Source (Free) Software who relentlessly
contribute to/make Open Source (free) software.

I just wanted to take some time to officially say *Thank You* for all
the good things which you guys/gals have made to my(/our) benefit, of
which has either saved my skin or improved my work efficiency.

To All of you, I say a Big Thank You for it.

Let no one tell you that you are Un-appreciated for all the hard work
you have poured into your relevant projects.

Seriously, Thank you.

What Cactid version?

Hi,

A few days ago I sent a bug report on the mailing list about Bonsai (js
graph zoom functions). I noticed another glitch: The "save" and "create"
(and likely others) buttons doesn't work (The browser appears to be loading
the page but nothing ever happens and the changes are not committed).
Interesting note is that "cancel" do work. I noticed this behaviour in the
user management page, the settings page and while trying to create new
graphs.

Apart from that Cacti seems to work pretty well under Opera. I can live with
that (I still have Firefox sitting around) but it would be nice if someone
could look into it...

Thanks

Thomas

Tony Roman
Cacti Developer

I'm trying to wrap my mind around how Nagios and Cacti "integrate"
(or, more specifically, how I can pipe Nagios output to rrdtool and
then have Cacti poll that rrd database). Both Nagios and Cacti are
installed ok, and now I'm trying to get n2rrd properly installed and
"gluing" together the two programs.

I've (I think) followed all of these instructions ok

http://n2rrd.diglinks.com/cgi-bin/trac.cgi/wiki/InstallationGuide

--n2rrd is unpacked to /etc/n2rrd ok
--nagios cfg files are edited properly
--made a /path/to/templates/service.t file (icmp.t to be exact)
--can reload nagios ok (with no errors)

...but now what?

I don't see any nagios logs being generated (step 14 of the HOWTO
URL), and I'm not sure where exactly these get generated (or how to
tell).

I'm assuming that nrd2graph doesn't have to be installed b/c that is
what Cacti will properly take care of?

Any help would be greatly appreciated.

Jee,

What utility are you referring to?

Latest version: 0.8.6j

I didn't look deeply into it as I never did js programming, but looks like
the only difference is that it performs different actions when the browser
type is Netscape (Mozilla in the user-agent).

Considering that IE isn't following standards and that we can IMHO safely
assume that unknown browsers are following web standards (and eventually
hack around reported incompatibilities) I believe we should rather perform
the different actions when the browser is IE.

I.e. change this:

	if (gBrowserObj.browser == "Netscape") {
		RightButtonPressed = (this.event.which == 3);
		// alert ("Net");
	} else {
		RightButtonPressed = (this.event.button == 2);
	}

to this:

	if (gBrowserObj.browser == "IE") {
		RightButtonPressed = (this.event.button == 2);
	} else {
		RightButtonPressed = (this.event.which == 3);
		// alert ("Net");
	}

everywhere it applies...

Thanks,

Thomas

I've tried the new utility.php. While this does seem to clear out
'some' of the ghost graphs (not all), it doesn't help at all with new
graphs that I create disappearing, or them disappearing when I change
data sources.

I still get this error when I try to create a brand new graph:
07/24/2007 01:02:46 PM - CMDPHP: Poller[0] ERROR: SQL Assoc Failed
"select   snmp_query_graph_rrd.snmp_field_name,   data_template_rrd.id
as data_template_rrd_id   from
(snmp_query_graph_rrd,data_template_rrd)   where
snmp_query_graph_rrd.data_template_rrd_id=data_template_rrd.local_data_template_rrd_id
  and snmp_query_graph_rrd.snmp_query_graph_id=   and
snmp_query_graph_rrd.data_template_id=50   and
data_template_rrd.local_data_id=2287"


This unfortunately has now gotten to the state where I'm having to
recommend we take Cacti out of production unless we can fix this.

Any idea at all what might be causing this and how I might go about fixing it?

Thanks,
Ras

Hi list,

This is something trivial but should definitely get fixed. Using Opera I
must fake the user-agent as Firefox to be able to zoom on graphs.

The feature works very well once I'm faking the user agent. In either case I
get the Bonsai JS code so looks like the problem is in that code

I believe both Firefox and Opera are following web standards, so shouldn't
any random user agent return the same code as Firefox?

I'd really appreciate to get the patch if it gets fixed.

Thanks,

Thomas

Please repeat your question at http://forums.cacti.net to draw attention from
more versed BSD guys. AFAIK, fmangeant there is a knowledgable cacti user

I've got it, I can create graphs as the apache user using rrdtool 
directly.  selinux is also disabled.

Apache account must have "read" access to the RRA folder and RRD's.

I recently moved a cacti installation from RHEL4 to RHEL5, upgraded the 
rrd files to work with rrdtool 1.2.x and everything seems ok except the 
graphs aren't showing up.  If I run the debug command manually, it 
produces a valid graph:

Anyone have any ideas?

    -Mike

Today while trying to create a Cacti graph (something I've been able
to do with no problems on this box before), I got a "permission
denied" error on the .rrd file that I was trying to access.

I shelled into a FreeBSD box, only to find that the
"/usr/local/share/cacti/rrd" folder was properly chmod'd and chown'd
with the Cacti user (like the instructions say).

I'm relatively new to FreeBSD (compared to other distros) and
unfortunately cannot get any good information out of anyone about what
changed on this server. (It seemed to be working a few weeks ago).

Might there be some sort of BSD version of SELinux going on here?  No
one has any info on what "changed" on the box to make it not work.
I've never had this problem on Cacti on the other distros I've worked
with (mostly Debian and RHEL/CentOS) and am wondering if it is a
FreeBSD oddity that I'm not understanding or if something in Cacti is
misconfigured.

Thanks in advance.

Hi all!

I need to create a graph to calculate the bandwidth excedent of clients.

For this last operation i use "Total: |sum:auto:total:2:auto|" like a 
comment, and it shows me 1.92 for exemple. Now, i like to use this 
number to calculate with an cdef function the excedent

If client have 1MB contracted they should will appear other line with 
92kb of excedent.

If everyone knows a manual more complet than cacti.net say me where i 
can get it plz.
Thank you very much! im noob with this program. :)

Thanks for your help, Rodney.

Shortly after I sent this email out, I figured out it.

Now I'm on to upgrading PHP 4 to PHP 5 on CentOS, which I understand gives
me better Cacti features.

1. Make sure MySQL is running.

2. Make sure you can first login to mysql with no password as root on 
the localhost by doing "[root@yourhost]# mysql -u root
