cacti-user Mailing List for Cacti

Hello!

Can you please change defaults for host counter of maximum number of
processes from the default 1000 to something like 10000 (or even more,
for example 20k ~ 30k). I'm asking you about it, since for loaded
servers, 1k max processes limit is too low, and though changing it
with a command line in RRD is easy, a mere user wont be able to do it
without knowing to rrdtool.

Thanks.

Cacti: 0.8.7d
Pa: 2.4
Discovery: 1.1

I have built a cacti server with discovery plugin. The idea is to scan some subnets for new servers and add them to cacti. The first time discovery runs, it works it discovers the devices and adds them to cacti. However, the second time it runs, it adds the same servers that was discovered. Why is it creating duplicate entries? Is there a way to prevent adding devices to cacti that are already there?

Please advise.

Thanks,

hasan

The reason for this is most likely, that deleting and recreating the rrd file 
updated it to the most recent MAX setting

Actually it is showing data now, so problem solved (by deleting and  
recreating the data source)

thanks! Andy.

Hi,

   I did initially create this with the default Max of 100, which I  
changed afterwards. I have also, just now, tried deleting and  
recreating the graph and data source, with the Max set to  
"90000000000" but its still not showing any data...

thanks Andy.

It may happen, that the data source MAX is set (default 100), which obviously 
would fail.

Hi,

   I'm trying to graph a file system usage using SNMP, from the cacti  
server I can see the OID data via snmpwalk:

# snmpwalk -c public -v 2c omega.ukgrid.net .1.3.6.1.4.1.2021.9.1.15.13
UCD-SNMP-MIB::dskUsedLow.13 = Gauge32: 604537600

But when I configure the data source/graph in Cacti I see no data, I  
do see SNMP polls from cacti to the server in question every 5 mins as  
expected.

My data source in Cacti is configured as

SNMP - Generic OID Template
Data Source Type "GAUGE"
OID ".1.3.6.1.4.1.2021.9.1.15.13"

What am I doing wrong? Thanks for any tips!

Andy.

All of a sudden, I see this problem on my windows cacti installed server:

Faulting application php-win.exe, version 5.2.5.5, faulting module ntdll.dll, version 5.2.3790.4789, fault address 0x0002a2ae.

Unable to run any php. I cannot even do php -help. No errors. Any ideas from the group? My windows version 2003 STD.

Thanks,

hasan

You do mean "disabled"? I'm not aware of such a "function".
But downed host detection may mark devices as "down"; that's a different meaning

Hi Chuck,

Were you able to get the AN100u template? Let me know as I am
looking for the same.

Cheers,
Frederic

Time to time, I am seeing that some devices are being disabled by cacti. Is there a rule somewhere if unable to connect via snmp for so many tries, then disable? If such rule exists, what is the exact criteria. I am definitely seeing this is happening and like to know why.

Cacti version: 0.8.7d

Thanks,

hasan

You may modify those aggregates manually. They are very normal graphs as soon as 
they have been created through AGGREGATE.
Only in many cases, creating them from scratch is faster.

But please know that Larry "TheWitness" implemented new functions, called 
aggregate templates, that may ease your task. To be honest, I did not yet work 
with those.

I'm running Cacti 0.8.7g with rrdtool 1.3.8 on Ubuntu Linux. Certain
date ranges on graphs don't work: the graph image doesn't show up
because graph_image.php returns a zero-length response.

When I have a particular graph and combination of dates, the failure is
reproducible. I'm not 100% sure that it's a particular set of dates. For
my own reference if nothing else, I'm currently trying from 2011-01-15
01:21 to 2011-03-15 01:21.

I added code before each popen() in lib/rrd.php to log the rrdtool
calls. When it works, I get an "rrdtool info FILE", "rrdtool fetch FILE
AVERAGE -s TIME -e TIME", and "rrdtool graph - ...". When it breaks, I
don't get the "rrdtool graph" call. One time I got an
"rrdtool /usr/bin/rrdtool - " call (that was it). I'm not sure what is
going on, but it's very strange.

Other than the logging I've added, I'm not seeing anything, even if I
turn on all the web and poller logging options.

Any ideas what to try next?

Thanks,
Richard

P.S. I tried to sign up at the forums and I never received my
confirmation email. I tried clicking the resend link a few days later
(today), but that didn't help either.

Hi,

Is it possible, practical, and safe (in terms of not losing data) to
modify an existing aggregate graph to add/remove items in the graph, or
is the only safe method to create a new version from scratch and
hide/remove the old version?

I have a dozen or so groups of aggregates, each pulling different data
from 30 hosts, and I need to remove one host and add another host to
each of the resulting aggregates.  It's been long enough since I created
the aggregates that I'm no longer all that sure of which steps are safe,
and not nuking the data is paramount. :-)

Googled for this for a while and still not sure.  Any help appreciated.

Hi,

This doc mentions rrdtool as requirements but not listed in the 
"Install the software" section.
yum install rrdtool

If rrdtool was installed than check crontab, and 
that rra dir writable by webserver user (www-data or apache)

Hello everybody

No advancement here. Is there anyone willing to help?

The only thing I noticed is that I am getting NaNs for the graph that
should contain something (the corresponding "LVS - Connections" graphs
plots something), but I couldn't make completely sense about rrdinfo output.

Can anyone please shed some light on this?

Hello

While I still wait for anyone who can shed some light on these issues,
I'll report on some advancements.

Any idea why this poller appears to run so slow?


> The funniest thing of all is that while the graphs for the remote
> datacenter are perfect, the ones for the local one are... barcode style,
> so to say.

The problem was the poller hitting the timeout before being able to
complete. That's quite strange anyway, since while a virtual machine
with four VCPUs, but only _one_ poller process was able to complete the
task before timeout most of the time, a physical machine with 16 cores
and one poller process couldn't. We increased it to 10 concurrent
pollers and now it runs OK.

- BUT -

I am still to understand where the bottleneck lies. This just makes no
sense at all, does it? Why a 4 CPU vm should complete in time while a 16
cores PM doesn't?

In the hope of ascertain it, I ran the poller by hand. The first time,
without disabling cmd.php from the crontab, it threw out errors like:

> ERROR: /opt/cacti-0.8.7g/rra/XXXXX_hdd_used_1384.rrd: illegal attempt to update using time 1299493294 when last update time is 1299493294 (minimum one second step)

and

> ERROR: could not lock RRD

The second time, I commented out the crontab line, and killed two
hanging processes after waiting for 10 minutes or so, these two:

> # pgrep -u cacti -lf
> 4892 /usr/bin/php -q /opt/cacti-0.8.7g/cmd.php 0 44
> 4894 /usr/bin/php -q /opt/cacti-0.8.7g/script_server.php cmd

They were probably leftovers of the first poller hand-run. A strace on
the first returned that it was stuck at a read call:

> # strace -p 4892
> Process 4892 attached - interrupt to quit
> read(7, ^C <unfinished ...>
> Process 4892 detached

while the second, which was a child process of the previous one) was
stuck on a write (!!!):

> # strace -p 4894
> Process 4894 attached - interrupt to quit
> write(2, "truncating signed value to 32 bit"..., 39^C <unfinished ...>
> Process 4894 detached

I had to kill -9 4894 to get rid of them.

A subsequent hand-run of the poller completed with no error, and didn't
appear to hang anywhere.


Errors due to locale settings, like the following, are gone after a
restart of snmpd with proper settings:

> These, probably, will just go away after setting LANG properly in the
> SNMP extension scripts:
>> 02/28/2011 11:50:02 AM - CMDPHP: Poller[0] Host[27] DS[1299] WARNING: Result from SNMP not valid. Partial Result: perl: warning: Falli

So... any clues?

Hi Everyone,

I am new to Cacti and SNMP in general. But I have been reading all day and
got Cacti installed on my CentOS. I want to start with simple monitoring of
the server itself with SNMP. I have followed a few guides including this:

http://www.cyberciti.biz/faq/fedora-rhel-install-cacti-monitoring-rrd-software/

I am stuck where the guide says:

--------------------------------------------------------------------------------------------------------

Click on "Create Graphs for this Host" link on top right side.

Select SNMP - Interface Statistics

---------------------------------------------------------------------------------

In my list I only see "SNMP - Generic OID Template" and there is nothing
else that has the word SNMP in it. Anyhow, picking any option and going to
Graphs just gives me a place-holder for the graph and there are no graphs.
It seems like I am missing a library package of php or maybe something from
RRDtools. But I also see this in the /var/log/httpd/error_log:

ERROR: opening '/var/www/cacti/rra/localhost_mem_buffers_8.rrd': No such
file or directory
ERROR: opening '/var/www/cacti/rra/localhost_snmp_oid_11.rrd': No such file

ERROR: opening '/var/www/cacti/rra/localhost_hdd_free_10.rrd': No such file

I installed the package using Yum repository.

Please advise as to how I should tackle this.

That was not a good idea. RRDTool only accepts increasing timestamps on update. 
So you will have to wait until system time >= last rrdtool update time

Hi Gandalf, I am using SNMP Auth Protocol and SNMP Privacy Protocol.
However, I am not using SNMP Context - do I need to do something special
here?

When you want to run "AuthNoPriv", then please do both
- do NOT use a privacy passphrase
- set privacy protocol to "NONE"
the last is required!
Starting with 087h, we will set AuthNoPriv automatically in case a
passphrase is 
missing. Until then, you must set NONE
