cacti-user Mailing List for Cacti

Greetings Cacti Users!

 

 

I modified Turbo Fredriksson's script to match my environment:

Which happens to be CentOS release 4.2 (Final) with perl-5.8.5-16.RHEL4

 

I had to disabled selinux to allow the script to run through snmp

 

[root@dns1 snmp]# ls -l bind9-snmp-stats.pl

-rwxr-xr-x  1 root root 17927 Oct 28 10:45 bind9-snmp-stats.pl

 

 

Problem:

[root@dns1 snmp]# ./bind9-snmp-stats.pl -a

<snip> (1608 Lines)

 

Just glancing through them I see my domains as entries. So I assume
everything is working.

 

 

/var/log/bind9-snmp-stats.log contains Also has one new line for each OID
with debug set to three.

 

 

Help doesn't work yet.

[root@dns1 snmp]# ./bind9-snmp-stats.pl --help

Undefined subroutine &main::help called at ./bind9-snmp-stats.pl line 599.

[root@dns1 snmp]# ./bind9-snmp-stats.pl -h

[root@dns1 snmp]# ./bind9-snmp-stats.pl ?

Undefined subroutine &main::help called at ./bind9-snmp-stats.pl line 599.

[root@dns1 snmp]#

 

 

Neither does Debug.

[root@dns1 snmp]# ./bind9-snmp-stats.pl -d

Can't open -d: No such file or directory at ./bind9-snmp-stats.pl line 623.

[root@dns1 snmp]# ./bind9-snmp-stats.pl --debug

Can't open --debug: No such file or directory at ./bind9-snmp-stats.pl line

[root@dns1 snmp]#

 

 

No major problem yet though.

 

Lets try the snmpwalk..

[root@dns1 snmp]# snmpwalk -v1 -On -c public localhost .1.3.6.1.4.1.8767.2.1

[root@dns1 snmp]#

 

I got Nada - Nothing..

 

 

However /var/log/bind9-snmp-stats.log has these new entries:

2005-10-31 10:23:17 => ARG=getnext

2005-10-31 10:23:17 => OID=OID_BASE.1.3.6.1.4.1.8767.2.1

2005-10-31 10:23:17 => OID_BASE.b9stNumberDomains.0

2005-10-31 10:23:17 OID_BASE.2.0 = 62

2005-10-31 10:23:17

2005-10-31 10:23:18 => ARG=get

2005-10-31 10:23:18 => OID=OID_BASE.1.3.6.1.4.1.8767.2.1

2005-10-31 10:23:18 => OID_BASE.b9stNumberTotals.0

2005-10-31 10:23:18 OID_BASE.1.0 = 6

2005-10-31 10:23:18

 

 

62 Domains is correct however.

 

Our Cacti server displays:

Turbo, can you point me in the right direction?

 

 

Thanks again for your contribution to the Cacti community.

Hi to all,

 

Do you have some information about threshold configuration ?

 

For example, I would like to send e-mail, modify color on my graph when my
router indicate no ip traffic or no session?

 

Thank you for helping

Wulfran

Thanks for the reply Jeremy,
Is this a system-wide setting somewhere?
I'm having trouble finding it - I've searched through all the cacti
sub-directories to no avail.
Could it just be using the default association for .pl files in windows?
Thanks,

Chris

hello,list.
    who have a mbmon template for the cacti?can mail to me , I'm a
lazy man. : -)
                                                                          h=
my.

I'm in the process of switching from MRTG to Cacti and I've got a couple 
of questions.

   1.

      In MRTG, there is a MaxBytes parameter, the primary affect of
      which is to place a red dashed horizontal line on the point of the
      y-axis that represents that max.  It's not a necessity, but for
      those already accustomed to seeing it, it's a help.  How do I
      accomplish the same in Cacti (or can I)?

   2.

      I like the ability to create a GUEST user, but I have yet to
      figure out what check box to check or uncheck in the User
      Management page for that user to disable the little wrench icon
      and so disable guest users both from mucking with and seeing any
      configuration data -- leaving it as it is will only cause
      confusion and phone calls to our help desk.

Thanks.

Hi

Anyone ever managed to graph number of connected streams etc for Real 
Helix Streaming servers?

thanks

hi,

recently i want to shifted our mrtg to cacti. adsl and
wilan radio i can successfully shifted to cacti, but
failed to trango radio.

i have created a xml file for atlas trango, which is-

<interface>
  <name>Get Trango Atlas Statistics</name>
  <oid_index>.1.3.6.1.4.1.5454.1.40.1.9.1</oid_index>
  <fields>
   <atlastrafficEthInOctets>
      <name>Eth Octets Throughput Receive</name>
      <method>walk</method>
      <source>value</source>
      <direction>output</direction>
      <oid>.1.3.6.1.4.1.5454.1.40.1.9.1</oid>
   </atlastrafficEthInOctets>
   <atlastrafficEthOutOctets>
      <name>Eth Octets Throughput Transmit</name>

      </atlastrafficEthInOctets>
   </atlastrafficEthOutOctets>
 </fields>
</interface>

the OID is taking from atlas mib file which we got
from their site and also this oid is working in my
MRTG server.

i have added this xml in Data Queries. When i want add
"Associated Graph" i got this warning-

Data Source:   	 traffic_in  	
Warning: Variable passed to each() is not an array or
object in /usr/share/cacti/site/data_queries.php on
line 356

Data Source:   	 traffic_out  	
Warning: Variable passed to each() is not an array or
object in /usr/share/cacti/site/data_queries.php on
line 356

although when i checked traffic_in and traffic_out and
click on Save Button got the following error-

Notice: Undefined index: dsdt_41_54_snmp_field_output
in /usr/share/cacti/site/data_queries.php on line 163

Notice: Undefined index: dsdt_41_55_snmp_field_output

Warning: Cannot modify header information - headers
already sent by (output started at

Please help how can i fix it.

meshbah

That would definitely be sensible.
I believe that there's been a fair bit of work done on 64-bit
support since the 5.0.x line (and 5.0.9 is over two years old)
So it's quite possible that problem has already been fixed.

The latest stable version is 5.2.2.rc2 (which will be released
as the full 5.2.2 very shortly).   If that code still suffers
from the same problem, then it would be useful to known ASAP
(ideally with a patch to fix it :-)).  We're gearing up to
release the next new version (5.3) soon after 5.2.2, so there's
a limited window for getting last-minute patches in before then.

The numbers I posted before were real, and still doing the same
thing:
ifconfig says:  TX bytes:34697827021 (33090.4 Mb)    (changed)
snmpwalk says:  IF-MIB::ifOutOctets.3 = Counter32: 0 (still zero)


This is on Centos3.x (should match RHEL3 with updates) in package
net-snmp-5.0.9-2.30E.19.  I suppose I can try building a newer version.

The Counter32 value will report the bottom 32-bits
(with the higher bits simply being discarded).

Remember that in the SNMP world, an individual Counter-based value
has no meaning.  Counter32 (and Counter64) object are used to
monitor the *difference* between two successive readings.


So:
    ifconfig eth1 ; sleep 60 ; ifconfig eth1

might report
    eth1   TX bytes:33033390619 (31503.0 Mb)
    eth1   TX bytes:33033391619 (31503.0 Mb)


while
    snmpget eth0 ; sleep 60 ; snmpget eth0

might report

    ifOutOctets.1 = 149182455
    ifOutOctets.1 = 149183455


The raw numbers are different, but the delta:

  33033391619 - 33033390619  = 1000
  149183455   - 149182455    = 1000

 is the same.   That's how SNMP Counters work.

What's supposed to happen when the value doesn't fit in a Counter32?
On a box where:
IF-MIB::ifDescr.2 = STRING: eth0
IF-MIB::ifDescr.3 = STRING: eth1
snmpwalk says:
IF-MIB::ifOutOctets.2 = Counter32: 149182455
IF-MIB::ifOutOctets.3 = Counter32: 0
but ifconfig shows:
eth0   TX bytes:149179729 (142.2 Mb)
eth1   TX bytes:33033390619 (31503.0 Mb)

This is an older version but with RH based systems it's hard to tell
what fixes have been backported to old version numbers.

Cacti (usually) just uses net-snmp's agent to get the data, so the issue is
probably "garbage in, garbage out".  I had seen problems a few months ago
(and posted here) where a 64-bit net-snmp agent will return a
greater-than-Counter32 value for a Counter32 value, which causes funny
results on the net-snmp 32-bit client side, especially when a snmpwalk is
being done. Interestingly enough, if the client was also 64-bit, then it
would "properly" report the bad value as it was transmitted.  I don't see
this problem anymore with recent versions of net-snmp.

If you want more information on what cacti sees, you can turn its log level
up to "medium", which will cause it to show the exact results in the log.
Further questions on this should probably go to a cacti forum.

Mostly unrelated question: do you happen to know who to
complain to about Linux x86_64 interface traffic stats
from net-snmp being incorrect as reported by cacti?
The target is Centos3.x (should be the same as RHEL3) with
cacti running on a 32-bit Centos4 box.  After a reboot the
values are correct for a while, then go crazy, showing
100 Meg traffic (the interface limit) most of the time.

At the risk of being a total pain, can I make a couple of
comments.  This README talks about problems with large
values (due to a "missing feature"), and later says:


                                           "The file sizes
  and baculaClientRetention{Job,File} etc is in KILO bytes,
  not BYTES as the SQL data is in. This is because I can't
  use a Counter64 ....
  As it is now, the value is a Counter32 which is ok."


If these MIB objects are meant to report "single" values
(such as the size of a file), then you probably don't want
to use Counter32.  A counter (whether 32-bit or 64-bit)
is concerned with the *difference* between two readings.
A single counter value is meaningless.

I'd suggest you replace these with Gauge32 or Integer32
syntax objects instead, (preferably before you release
the MIB publicly! :-)), depending on whether you need
unsigned or signed 32-bit values.


I'm not sure whether the same applies to the ClientRetention
objects or not - I didn't find the relevant DESCRIPTIONs
particularly meaningful :-)


It's also not true that Counter64 is the only way to report
large file sizes.   There are at least two techniques that
could be used to address the 64-bit limitations.  One way
(as I think I mentioned on the net-snmp list), would be to
report the file size using two separate 32-bit objects - one
for the lower 32-bits of the value, and one for the higher.


Another technique would again be to use two objects - one
reporting the size of the file in "blocks", and the other
reporting the size of an individual block.  That allows
you to handle larger file sizes (at the cost of a coarser
granularity).   See HOST-RESOURCES-MIB::hrStorageTable
for an example of this approach.



I must also correct a misunderstanding over the future of
64-bit handling in Net-SNMP pass-through support. It is
true that this mechanism currently only supports 32-bit
values (due in part to the historical background you refer
to). But it is inappropriate to say that:

    "Counter64 isn't (and will not) be
       implemented in net-snmp"

Firstly, net-snmp *does* support the Counter64 syntax - it's
just the pass-through mechanism where this is currently
missing. Secondly, I'm fairly sure that at some point, we
*will* extend this mechanism to cope with the SNMPv2 additions.
It's been on my ToDo list for a while now.

My words of caution were just meant to indicate that this
was unlikely to happen in the immediate future - not that
we were refusing to fix it.  Sorry if I gave you the wrong
impression.




I'll do a proper hatchet job on your MIB when I have a bit
more time :-)


Dave

[Sorry for the cross-post people!]

For the last two weeks, I've been trying to interface the Bacula
SQL database with SNMP.

The script is now in such a state that it's actually RELEASABLE
and USABLE but not quite done regarding the Cacti integration -
still need to finish the SNMP Query XML file...

Have a look at http://www.bayour.com/bacula-snmp/ for more
information, files. Especially the README.txt.


Thanx MUST go to Dave Shield on the net-snmp-users list. Without
him, this project would have stranded!

I've just noticed in the source for rrd.php that this is normal:

/* FOR WIN32: Escape all colon for drive letters (ex. D\:/path/to/rra)
*/
			$data_source_path =3D str_replace(":", "\:",
$data_source_path);=20

So I'm guessing that's not the problem.
I get 4 command windows pop up and the disappear again quickly
afterwards every 5 minutes.
They just have one line in saying something like:

cannot find module (NONE) at line 0 (none)

It goes too fast to catch all of it.
Any idea if this is problem (and what it means?)

Thanks,

Chris

Dear all,

I am creating graph, for windows memory, disk and cpu usage.
It is required to compile Win32::OLE perl module to compile on redhat =
cacti server.

I am usnig Win32-OLE-0.17.tar.gz.
When I Run: perl Makefile.PL ...... shows OK
But when i tried next step, It gives error as:
Makefile: 978: *** missing separator. Stop.

Pls help to compile this module on redhat-9.

Hi everyone,
I've installed cacti on windows and it seems to be getting snmp data as
the logs show the following:

 10/20/2005 03:59:01 PM - CMDPHP: Poller[0] Host[3] DS[18] SNMP: v1:
10.42.20.24, dsname: traffic_out, oid: .1.3.6.1.2.1.2.2.1.16.5, output:

2630799866

Yet it doesn't seem to be storing the data it receives.
I guess this could be because of some wrong rrdtool commandlines, for
example, the following:

c:/cacti/rrdtool/rrdtool.exe graph - \

Some distributions (Mandriva being one of them), have a separate RPM for
php-session.   Check to see if it is installed - or do 'php -m' and see i=
