Dear Mod & Master,

i have snmp information, snmp error
In device - localhost, snmp information not error
but in other device (other host or client), snmp error

SNMP Information
SNMP error

So a graph not shown

please suggestion, how to check this problem
hmm that's i'm not configure well the SNMP?

my snmpd.conf files setup :
com2sec local localhost public
group MyRWGroup v1 local
group MyRWGroup v2c local
group MyRWGroup usm local
view all included .1 80
access MyRWGroup "" any noauth exact all all none
syslocation Unknown (edit /etc/snmp/snmpd.conf)
syscontact Root (configure /etc/snmp/snmp.local.conf)
pass .1.3.6.1.4.1.4413.4.1 /usr/bin/ucd5820stat

i tried to test poller.php, there are some error :
#php poller.php
02/10/2012 02:14:52 PM - POLLER: Poller[0] WARNING: Cron is out of sync with the Poller Interval! The Poller Interval is '300' seconds, with a maximum of a '300' second Cron, but 275991 seconds have passed since the last poll!

You have configured snmp to only respond to localhost requests:

Code: Select all

com2sec local localhost public

You should replace 'localhost' with the IP of your Cacti box.

[graver347]

am i need to configure snmpd.conf in cacti client too?
with add some code like this :

Code: Select all

com2sec  readonly   [ip_cacti_machine]    your_community

my next question, why localhost can't shown graph
snmp and others is ok, no errors in localhost

thanks for your help

[Linegod]

Leave the cacti one as localhost.

[graver347]

For your info
This new cacti is migrate from one server to another server (called new server)
I think that's no problem with cacti client

any idea to check why it's still not connect and shown graph?

[graver347]

Anyone can help again?

this is my RRDTOOLS info for localhost - memory usage graph:

Code: Select all

RRDTool Command:

RRDTool Says:

OK

SNMP Information :

Code: Select all

RRDTools looks fine, so why the graph can't shown
Thanks for help dear master

[Linegod]

Have you changed the log level to debug and checked for errors?

[graver347]

Do you mean set in cron like this?

Code: Select all

*/5 * * * * /usr/bin/php -q /var/www/html/cacti/poller.php --force --debug > /var/local/log/poller.log 2>&1

i got error (date : 10-feb-2012) :

Code: Select all

# cat poller.log

please correct if im wrong
Thank you

I don't think I mentioned cron, but obviously you didn't have it set up before, as 263700 seconds have passed since the last poll

Take the --force --debug out, and set debug through the GUI.

Then check that you can do an snmpwalk of the devices from the console.

[graver347]

i don't understand about "set debug through the GUI"
it's debugging in (Verbose Query) like image @ attachement?

the result is :

i'm so tired about that, it's look like fine and all device status Up
but graph not shown

as you suggest, i was take out --force --debug before

thanks for your respon

[graver347]

Anyone can help again?
I thinks the root cause is the poller

what should i do, first i must solve the localhost graph problem
snmp is ok, rrdtool is ok

i test to copy rrd files from old_server to new_server, graph is shown..because poller is not run properly, graph data not refresh or update in new server.

thanks for your help
i feel stuck :-s

[noname]

>> i don't understand about "set debug through the GUI"

See 'Settings -> General -> Poller Logging Level'

[graver347]

i have change Poller Logging Level to DEBUG, then in the top shown "Save Successful."
but in Poller Logging Level combox still back to default (LOW - Statistic and Error)

I don't know why it's not change to DEBUG
Any suggest?

[graver347]

Ok, first i think i must solve about snmp problem
any package that i'm missing in migration process? so make the localhost graph not shown/update

and what setting that i must do to make snmpwalk to cacti client have a respon

cacti server
--> client 1 to get graph
--> client 2 to get graph
--> etc

need help

[noname]

i have change Poller Logging Level to DEBUG, then in the top shown "Save Successful."
but in Poller Logging Level combox still back to default (LOW - Statistic and Error)

I don't know why it's not change to DEBUG

To force to change log level,

Code: Select all

Before:
% mysql -uUSER -p -e 'SELECT * FROM settings WHERE name="log_verbosity";' cacti
+---------------+-------+
| name          | value |
+---------------+-------+
| log_verbosity | 2     |
+---------------+-------+

Change:
% mysql -uUSER -p -e 'UPDATE settings SET value=5 WHERE name="log_verbosity";' cacti

After:
% mysql -uUSER -p -e 'SELECT * FROM settings WHERE name="log_verbosity";' cacti
+---------------+-------+
| name          | value |
+---------------+-------+
| log_verbosity | 5     |
+---------------+-------+

I think, making trial and error without clues (= log) is like wandering in the dark..
