Hello, thanks for answer,

The fact is I already read this how to and my snmp seems to be well 
configured, I didn't add 
"     rocommunity public "

Because I already have a working  community, and anyway, I tried it, it 
changed nothing...
And when I try manually the request to show BytesOut and ByteIn, it work 
nice...
Basically, it work manually, informations catched by cacti are correct but 
when I want to add a query, it says no answer, try to run verbose query, 
and if I click on it, I have a Network_tcp error.

This depends on permissions given to different SNMP views defined in
/etc/snmp/snmpd.conf
Best is to visit docs.cacti.net, see the HowTo section and read Frederic

Yeah,

I confirm, Gandalf (from forums.cacti) said you can use php-snmp OR 
net-snmp...  Issue must be somewhere else...

Thanks for your help,

Re: [cacti-user] Unable to create graphs for snmp request [C1]






I guess net-snmp and php-snmp are different packages, for different
purposes. In my cacti experience, cacti needs php-snmp to work
properly.

At least, it is listed in the FreeBSD port:
http://www.freebsd.org/cgi/ports.cgi?query=cacti&stype=name&sektion=all

Hello,
  I have installed cacti version 0.8.7a. I cant get it to graph squid on the proxy servers I am monitoring. I have imported the XML templates for Squid to the cacti machine and I included the following to the snmpd.conf and squid.conf file in the server squid is running on.
   
  Snmpd.conf
  proxy –v 1 –c public 127.0.0.1:3401 .1.3.6.1.4.1.3495.1

  snmp_incoming_address 0.0.0.0
  snmp_outgoing_address 255.255.255.255
   
  On the Associated Graph Template of the device I added, I can graph 
  SNMP – Generic OID Template
  Squid – Cache Objects
  Squid – HTTP Data
  Squid – HTTP Requests
   
  But on the Associate Data Queries, all the data queries show 0 items and 0 rows
   
  When I debugged Webcache – Squid Core, I get:

Hi all,
I already opened a case on the forum, but i get no answer, so I try here. 
I installed Cacti successfuly (I guess) few days ago, I can create "memory 
usage" or "disk space" properly for local host but when I try to add an 
"interface statistics" graph for a network device (a switch here), I got 
this in creation graph page:



Data Query [SNMP - Interface Statis


This data query returned 0 rows, perhaps there was a problem executing 
this data query. You can run this data query in debug mode to get more 
information.










Actually it is the same for almost all request (excepted Unix), and when I 
clic on run this data query in debug mode, I have a tcp error:
Network Error (tcp_error)
A communication error occurred: ""
The Web Server may be down, too busy, or experiencing other problems 
preventing it from responding to requests. You may wish to try again at a 
later time.
For assistance, contact your network support team.

Of course the server don't really have issue, all other applications on it 
are working properly. All path are ok, and when I run an snmp request 
manually, it works well... I didn't get the snmp.so library of php-snmp 
because I read on the net you can use the net-snmp which was alerady 
installed. What do you think could be the matter? Any informations could 
be really helpfull. Thank you guys!

Regards,
Pierre.

Please open same issue at forums.cacti.net and provide a screenshot. Most often,
this is caused by incorrect "Settings->RRDTool Utility Version" or a wrong rrd
font file name

Hello Guys,

I'm trying to replace the MRTG for Cacti.

I didn't have any problem to do that. However after added some hosts I tried to create the graphs and it was the problem.
The graphs is breaking, there is no images.

What I must do ?

Thank you.

Cheers,
Hugo

Edit your php.ini file, set the memory_limit to 128M.  Then, restart Apache.

TheWitness

Hello all, I did a hell lot of search, but nothing help me 'till here, 
here is my problem with the maximum of informations possible:
I followed this : http://docs.cacti.net/node/137, to create a graph on one 
of my devices, but when I click the "create"button, i got a Network Error 
(tcp_error). Previously I had a "exceeded timeout of 30 secondes" from 
php, but Changed the php.ini file. I don't think it is a server issue, 
because i have some other applications running and everything works 
great... 

The devices look to be created (it appear in the devices list), but the 
main part of the time, I don't have the "snmp information" at the top of 
the page when i edit the device (mainly just "device is alive") 

When I click on "create a graph", the data query part display that : 
"This data query returned 0 rows, perhaps there was a problem executing 
this data query. You can run this data query in debug mode to get more 
information." 

but if I try to run in debug mode, I have a tcp error again. 

The poller don't seem to create the rrd files in /rra, I always have this 
kind of error: 
"ERROR: opening 
'/opt/home/netadmin/src/cacti-0.8.7a/rra/sacctok106_sg_asia_5min_cpu_16.rrd': 
No such file or directory" 

it looks like a permission issue but the user executing the poller (by 
crontab) and the owner of /rra are the same (anyway, for testing, I put 
777 to /rra). Only the user for mysql database have a different name (but 
well informed in config.php. 


All the path in settings looks corrects, file are found and working 
manually launched. 

When I run poller.php or cmd.php manually, I have no display at all. 

I'm not using SElinux. 

I tryed to follow gandalf's file about suppressing nan, but I did find any 
solution. 

I succeed to run the data query in debug mode for ucd/net - Get Monitored 
Partitions (not possible for snmp), it gives me that: 
+ Running data query [2]. 
+ Found type = '3' [snmp query]. 
+ Found data query XML file at 
'/opt/home/netadmin/src/cacti-0.8.7a/resource/snmp_queries/net-snmp_disk.xml' 

+ XML file parsed ok. 
+ Executing SNMP walk for list of indexes @ '.1.3.6.1.4.1.2021.9.1.1' 
+ No SNMP data returned 
+ Found data query XML file at

+ Found data query XML file at 
'/opt/home/netadmin/src/cacti-0.8.7a/resource/snmp_queries/net-snmp_disk.xml' 



which look ok, but it still tell me "This data query returned 0 rows, 
perhaps there was a problem executing this data query"

If you have SNMP read access to the switches, this is doable.

But it is a task to relate all switch ports to the related servers and to
provide access to those graphs only, that relate to servers of each respective
client.
All this can be done with cacti
Reinhard

Hello,

I think this should be easy if I owned the switches, but the colocation 
facility owns the switches.
How can I make cacti graph bandwidth info for multiple servers?  Here's 
what I want to do and explain what cacti can do.

I need it to create bandwidth usage graphs where it would grab the info 
from SNMP from the switches managed by the colocation facility.  The 
software would need to ONLY be installed on server #1.  Each dedicated 
server client would have their own login to server#1 to see their own 
dedicated server's bandwidth usage graphs.  I don't want any software 
installed on client servers (only on server#1).  I want the software to 
read from the SNMP from the colocation facility's owned switches.
I don't want to install SNMPd on each client server.

Thank you.

Elijah,

It's a snap of a plugin to write, but more requirements would, of course, be required to complete.  RRDtool, combined with Cacti, can produce excellent output for reporting when combined with a database to store short and long term statistical data.  However, storage in RRDtool is the only way to go for long term interval based data.

There are an abundance of howto's at http://docs.cacti.net.  But in general.

1) Make sure your poller cache has entries that collect the data for the host.
2) Make sure your poller is running properly (run it manually once of twice)
3) Make sure you don't have any RRDfile permission issues
