Cactid 0.8.6g problem

farhan · Post by **farhan** » Tue Jan 17, 2006 2:01 am

Hi folks,

Cactid has not been polling since i upgraded to 0.8.6g. It has been

missing the polling.

Platform information:

mysql = 4.1.12
PHP = 4.3.9
net-snmp = 5.1.2-11

Please help me.

Error: The output of php poller.php is

Waiting on 1/1 pollers.
01/17/2006 04:21:31 PM - POLLER: Poller[0] Maximum runtime of 292 seconds exceeded. Exiting.

PHP Warning: pclose(): 47 is not a valid stream resource in /usr/local/cacti/lib/rrd.php on line 48

It looks like RRDtool is misbehaving as the stream is not opened when poller.php is attempting to close. Is the path correct in Settings->Paths?

Thanks for prompt reply. i have checked that rrdtool path is correct. It was working fine before upgradation. And one more thing I noticed is that if I run php cmd.php and then php poller.php it works fine and it is populating thes graphs. so, in the mean time i am running the crontab job which runs php cmd.php 1st and then php poller.php.
Please help me to solve this problem.

Thanks,

Farhan

For me to help you we have to do it online. Right now your profile is quite sparse. You need to provide country and timezone information in your profile along with IM information. I will have to access your box to do the fix and I can't do it from my office EST (Detroit, MI/USA).

Also,

There is a patch to Cactid 0.8.6g. I believe that it is in the Announcement's forum. Don't know if raX has published. You can goto the web based SVN for "BRANCH_0_8_6" and download thefollowing updated files:

poller.c
cactid.h

Then re-make cactid and your problems might go away.

Thanks for suggestions. I have already replaced these files from

http://forums.cacti.net/about11424.html. But the situation is same. Any

other idea? Why is it happening

Thanks,

The last users problem was that it appears that a "default" cactid.conf file was placed in the Cactid binary directory. If you rename that file, the problem should correct itself.

If you simply open a shell and cd to the cactid binary directory and run "./cactid 0 10", you will see and authentication error displayed.

The cactid.conf file was the original cacti.conf file I had previously! I contained the correct database name, username and password - as per the includes/conf.php config.

When I rename the cacti.conf file to cactid.conf.bak - i.e. I do not have a cactid.conf file - I get the following error:

Code: Select all

CACTID: MYSQL: Connection Failed: Access denied for user 'cactiuser'@'localhost' (using password: YES)

However, when I rename the file back to cactid.conf - I get the following error instead:

Code: Select all

CACTID: Using cactid config file [cactid.conf]
CACTID: Version 0.8.6f starting
Segmentation fault

When you say:

If you rename that file, the problem should correct itself

Do you mean that cactid does not require this cactid.conf file now?

The contents of my cactid.conf file is (password removed):

Code: Select all

DB_Host         localhost
DB_Database     cacti
DB_User         cactiuser
DB_Pass         *****
#LogFile         /var/log/cactid.log

As stated previously, this is the same details as my config.php file. I am able to access the Cacti web interface OK - thus, I assume those usernames and password are correct; and since they have been working previously!

Mon,

Can you rerun "autoconf" followed by "./configure" and then remake the package. Before that, double check that you have the most recent version's of the files. I diid post the most recent ones and I believe that you said that you updated to them.

What was you OS?

TheWitness

also, if you are receiving a stackdump file. I would like to get a copy of the file. It will be located in your cactid binary directory. The other option is to run "gdb cactid" followed by "run 0 10". Wait for it to segfault and then run the "backtrace" command and post the results.

TheWitness,

I am using Fedora Core 4

I installed autoconf and re-configured and re-maked the cactid executable - but same errors.

There is no stackdump file.

I installed gdb and followed the procedure your gave - here is the dump of it:

I tested the previous versions of cactid - down to 0.8.6d - which is the previous version I was using, and which is the version I am using in another (working) cacti 0.8.6g installation.

All the different versions of cactid even 0.8.6d shows a segmentation fault when testing with "./cactid 0 10"!!

Thus, could it be something else? Such as rrtool/php/mysql? - I am using versions:

rrdtool = 1.0.50
php = 5.0.4
mysql = 4.1.16

Is it possible to revert back to Cacti version 0.8.6g? What is the procedure for this - I already have this version in a backup directory, but is there any database implications when reverting back to this version?

Regards,

Mon

Could be. Can you dump your database and e-mail to me. I have the day off today and may be able to run a session with you online. Also, check your glibc. Make sure you are not running the development version, it had several issues.

TheWitness,

I copied over the working cactid 0.8.6c executable from my other Cacti server and I do not get the segmentation fault.

Instead I get such errors:

Code: Select all

CACTID: ASSERT: 'SNMP ERROR<SNMP ERROR' failed. Recaching host 'a.b.c.d', data query #1
CACTID: ASSERT: 'SNMP ERROR<SNMP ERROR' failed. Recaching host 'v.x.y.z', data query #1
CACTID: ERROR: Problem with MySQL: Duplicate entry '0-1-61:1' for key 1
CACTID: ERROR: Problem with MySQL: Duplicate entry '0-1-62:1' for key 1

I don'yt know if this is of any help. May be it is some kind of mysql problem?

Below is the mysql version from my working FC2 machine:

php-mysql-4.3.10-2.4
mysql-3.23.58-16.FC2.1
mysql-server-3.23.58-16.FC2.1

Below is the mysql version from my non-working FC2 machine:

mysql-4.1.16-1.FC4.1
mysql-server-4.1.16-1.FC4.1
mysqlclient10-3.23.58-6
mysql-devel-4.1.16-1.FC4.1
libdbi-dbd-mysql-0.7.1-3
php-mysql-5.0.4-10.5

Here is the glibc versions on my non-working FC4 machine:

Code: Select all

glibc-headers-2.3.5-10.3
glibc-2.3.5-10.3
glibc-devel-2.3.5-10.3
glibc-common-2.3.5-10.3
glibc-kernheaders-2.4-9.1.94

Here are the glibc versions on my working FC2 machine:

Code: Select all

glibc-common-2.3.3-27.1
glibc-2.3.3-27.1
glibc-headers-2.3.3-27.1
glibc-devel-2.3.3-27.1
glibc-kernheaders-2.4-8.44

I'm sorry - due to our security policy, I cannot give you access to my cacti database

- so we will have to try to troubleshoot this another way.
