Problems of operation with SOLARIS

[KARLOS]

I have all the steps for the configuration of cacti in Solaris 9, but at the moment of test it appears the problem of snmp error.

The programs that have installed are:
Cacti 0.8.6b
PHP 4.1.7
Apache 2.0.51
rrdtool-1.0.49
package netsnmp-5.1.1-sol9-sparc-local

Have you stopped Solaris SNMP daemons and started NET-SNMP?

Execute:

$ snmpget -v 1 -c public localhost sysUpTime.0

and post the result,

After having stopped SNMP daemons i have tried ...

bash-2.05# snmpget -v 1 -c public localhost system.sysUpTime.0
Timeout: No Response from localhost.

First, check if NET-SNMP is up and running:

$ ps -ef | grep snmp

If it's running, check if your community is "public" (check your snmpd.conf file).

[KARLOS]

bash-2.05# ps -ef | grep snmp
root 19935 1 0 16:43:42 ? 0:00 ./snmpd

[KARLOS]

I understand the community is public:

bash-2.05# more snmpd.conf
# Copyright 1988 - 07/17/00 Sun Microsystems, Inc. All Rights Reserved.
#ident "@(#)snmpd.conf 2.24 00/07/17 SMI"

# See below for file format and supported keywords

sysdescr Sun SNMP Agent, UltraAX-i2
syscontact System administrator

#

#
read-community public
#write-community private
#
trap localhost
trap-community SNMP-trap
#
#kernel-file /vmunix
#
#managers lvs golden
managers localhost

...

[zanaguara]

That snmpd.conf file is Solaris SNMP daemon config file, not NET-SNMP.

Try:

stop and disable Solaris SNMP daemons:

Code: Select all

# cd /etc/rc3.d
# ./S76snmpdx stop
# ./S77dmi stop
# mv S76snmpdx _S76snmpdx
# mv S77dmi _S77dmi

now start NET-SNMP:

Code: Select all

/path1/snmpd -c /path2/snmpd.conf 

You have installed NET-SNMP sunfreeware package instead of compiling it, so path1 and path2 depend on how that package has been compiled. I suppose path1 and path2 are going to be under /usr/local.

Note that NET-SNMP snmpd.conf file shouldn't have the Sun Microsystems copyright stuff.

You could edit your snmpd.conf file by hand or you can do:

Code: Select all

./snmpconf -g basic_setup

to start an interactive basic configuration process.

I am not sure if i am rigth. But i think a graph should appear even if the snmp had gathered no information.

(I am not 100% sure of this, so if I am wrong corrections are of course very welcome).

There is one poller setting called "Downed Host Detection" (Settings -> Poller)

If "Downed Host Detection" is SNMP and your SNMP daemon is down, your poller is not going to poll that host. So no graphs are going to be updated.

If you feed your graphs via scripts you can chage the "Downed Host Detection" setting to ping.

In device the status puts unknow, in spite of this, the dates queries appear different items and rows.

In the data sources, in Debug Mode, i can see the files are created. When i go to rra folder not appear it.

[zanaguara]

Could you please send your log file in debug mode?

Go to Configuration -> Settings -> Poller Specific Logging and select DEBUG.

Then wait until poller is executed at least once.

Hi Javier,

It is like if it was imposible to write anything at all in rra and log files. So i cannot send you a log file.

It can be seen information in the View Poller Cache [9 Items]. For instance,
Data Source: eretza2 - Memory - Free
RRD: /usr/local/apache2/htdocs/cacti-0.8.6b/rra/localhost_mem_buffers_3.rrd
Action: 1, Script: perl /usr/local/apache2/htdocs/cacti-0.8.6b/scripts/linux_memory.pl MemFree:

Data Source: eretza2 - Memory - Free Swap
RRD: /usr/local/apache2/htdocs/cacti-0.8.6b/rra/localhost_mem_swap_4.rrd
Action: 1, Script: perl /usr/local/apache2/htdocs/cacti-0.8.6b/scripts/linux_memory.pl SwapFree:

(...)

But there is nothing in View Cacti Log file.

It says

ERROR: opening '/usr/local/apache2/htdocs/cacti-0.8.6b/rra/localhost_proc_7.rrd': No such file or directory

and i get another error/warning:

Warning: unlink(/usr/local/apache2/htdocs/cacti-0.8.6b/log/cacti.log): Permission denied in /usr/local/apache2/htdocs/cacti-0.8.6b/utilities.php on line 158

Regards,

Ok, it's a permissions problem.

- which user is executing poller.php?
- execute:

$ grep User /path_apache_conf/httpd.conf
$ ls -d /usr/local/apache2/htdocs/cacti-0.8.6b

and post the results.

Hi javier,

i get these results:

User nobody

bash-2.05# ls - d usr/local/apache2/htdocs/cacti-0.8.6b
-: No such file or directory
d: No such file or directory

Ok, apache is being executed by nobody.

Please execute:

bash-2.05# ls -d /usr/local/apache2/htdocs/cacti-0.8.6b

Note that there is no space between the "-" and the "d".
