device added but no graph

i have installed cacti on a debian machine version 6.0.7
everything is working great localhost graphs are fine.

actually i have another virtualization server on Debian and i want it to
monitor with cacti however the good thing is i can create a device and so
far log shows i can successfully add the device, even i can create graphs
as per the status says graph created. but in graph tab i can conly see
localhost. no new devise has been showed up in that tab.
here is the detail of my device when i add one

Basehost (10.xx.xx.13) SNMP Information
 *System:*Linux virt-dev 2.6.32-19-pve #1 SMP Wed May 15 07:32:52 CEST 2013
x86_64
*Uptime:* 404058 (0 days, 1 hours, 7 minutes)
*Hostname:* virt-dev
*Location:* Sitting on the Dock of the Bay
*Contact:* Me me <at> example.org

here is the device tab snap which shows that device is successfully
connected and up

i see no logs in cacti log file except this line

05/23/2013 05:30:02 PM - SYSTEM STATS: Time:1.1582 Method:cmd.php
Processes:1 Threads:N/A Hosts:3 HostsPerProcess:3 DataSources:19

Thank you,

Varying table index for disk I/O stats

[0.8.7i from Ubuntu 12.04 package]

I am monitoring disk I/O stats using
http://docs.cacti.net/usertemplate:data:host_mib:diskio

The SNMP query template is at the end of this mail. Here's an example of the
data it's collecting:

$ snmpwalk -On -v2c -c XXXXXX XXXXXX 1.3.6.1.4.1.2021.13.15.1.1 | grep '\.55 '
.1.3.6.1.4.1.2021.13.15.1.1.1.55 = INTEGER: 55
.1.3.6.1.4.1.2021.13.15.1.1.2.55 = STRING: md127
.1.3.6.1.4.1.2021.13.15.1.1.3.55 = Counter32: 2775494144
.1.3.6.1.4.1.2021.13.15.1.1.4.55 = Counter32: 1303653888
.1.3.6.1.4.1.2021.13.15.1.1.5.55 = Counter32: 12228936
.1.3.6.1.4.1.2021.13.15.1.1.6.55 = Counter32: 1514190
.1.3.6.1.4.1.2021.13.15.1.1.9.55 = INTEGER: 0
.1.3.6.1.4.1.2021.13.15.1.1.10.55 = INTEGER: 0
.1.3.6.1.4.1.2021.13.15.1.1.11.55 = INTEGER: 0
.1.3.6.1.4.1.2021.13.15.1.1.12.55 = Counter64: 5680722259456
.1.3.6.1.4.1.2021.13.15.1.1.13.55 = Counter64: 645548748288

This works fine, except for the following issue.

Suppose I decide to monitor stats for device "md127". Cacti internally maps
this to the table row number, say x=55 as shown above.

At some point in the future, perhas due to reboot or device insertion or
removal, the table may change.  For example, md127 may become x=54.

When this happens, Cacti starts graphing the wrong value (or no value at

Adding links to cacti graphs

Hello,

I'm working on new cacti graphs and one idea that I was working with was providing a link on the graph legend to
a more detailed explanation of the graph. Is there any way of adding a link on the graph or somewhere in cacti
for this type of thing? 

Thanks,
mjr

CPU load graph is not showing for some machines.

Few graphs like cpuUsage, loadAverage, memoryUsage  are not being displayed
on the browser for couple of machines . I am not sure if it is
configuration problem because i have not admin password for cacti. Some
machines are displaying 23 graphs including mentioned graphs but some are
displaying 20 . It is clear that cacti is working for machine but not
showing only 3  graphs. I may need to configure on server side but i am not
sure. I never worked on cacti before. Can anybody help me to diagnose this.

Thanks,

Templates for graphing Cisco CBWFQ Policy

Dear All,

I like to use the template on this thread and appreciate the author so much:

http://forums.cacti.net/viewtopic.php?f=12&t=42599&start=0

which is about  graphing Cisco CBWFQ Policy.

I need some help to extend the template so that the graph indices on the 
"Create Graph" for a device are listed in a more readable way. Right 
now, each graph index is listed as a plain number. A more readable one 
should contain interface name/description and class-map name.

I found the following list of OIDs from a script by Maxstoner on this 
thread: http://forums.cacti.net/about33275.html and this

Dynamically monitor devices info.

Greetings.

I'm actually running cacti on my network to monitor devices info like CPU
usage, interfaces traffic and more. Sometimes I monitor other devices who
has either a static address associated to them or a FQDN to resolve its
current address. The problem is, I'm going to need to monitor devices who
has dynamic address and no name to resolve it.

The devices are clients internet devices who raise PPPoE connections on a
Mikrotik router, however they receive dynamic address each time they
connect so my SNMP loose track of them every time they disconnect.

I'm thinking on configuring the Mikrotik router to automatically send the
PPPoE statistics so the SNMP so the manager don't need to query the router
to fetch de information. Instead, the information will be sent to the SNMP
Manager to be harvested and only the registered (or pre selected) devices's
info will be plotted and displayed, the rest will be discarted.

Whats the best way to do this?

Energy of writing to set-associative cache

Hi All,

On fast mode, the cache tags and data ways are accessed in parallel in
set-associative cache. When writing to this cache, I think the tag check
will perform first and the data will write to the cache after determining
which way to write. Thus, the write operation will only access one way of
the cache, and the energy should be much lower that read operation.
 However, I found that the write and read energy of such cache is the same
in Cacti.

I was wandering if I made some mistake on this?

Can anyone give me some ideas?

Any idea will be appreciated!

Thank you in advance!

Zhong

Polling Latency on cacti 0.8.8a

Hello all,

I am facing a strange problem, this morning my time polling is mounted
arrow(see attachement) following
the correction of the path to a template that does not work (In the data
input method, the path for a PHP Script Server was wrong).
When i do a php /usr/share/cacti/poller.php i have a lot of "Waiting on 3
of 15 pollers."
In my cacti.log, i see in loop :
