thumbnail for map not created yet

[Howie]

And there are still NO entries in the cacti.log for weathermap?

[andrewtee2001]

Hi Howie,

Sorry I wasn't around yesterday. There is no Weathermap related errors in cacti.log, mostly are SNMP related.
Non significant weathermap error, but lots of PHP error in httpd/error_log.

I have attached the cacti.log, httpd/access_log, httpd/error_log.

I will try to download a sample map from the internet and put it into my weathermap and test my luck.

Thanks & Best Regards,
Andrew

Hi Howie,

Recheck. Refer to the diagram below, is the permission and file ownership correct?
/usr/share/cacti/plugins/weathermap/configs ---
/usr/share/cacti/plugins/weathermap/output ---

Hi Howie,

Say I followed a guide from internet, and executed below commands...

[root@MyCacti /]# cd /usr/share/cacti/plugins/weathermap/
[root@MyCacti weathermap]# ./weathermap --config configs/example.conf --output=example.png --htmloutput example.html

PHP Warning: fopen(configs/example.conf): failed to open stream: No such file or directory in /usr/share/cacti/plugins/weathermap/lib/Weathermap.class.php on line 1787

PHP Warning: file_get_contents(configs/example.conf): failed to open stream: No such file or directory in /usr/share/cacti/plugins/weathermap/lib/Weathermap.class.php on line 3078

PHP Warning: strftime(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'Asia/Kuala_Lumpur' for 'MYT/8.0/no DST' instead in /usr/share/cacti/plugins/weathermap/lib/Weathermap.class.php on line 3098

No idea about the permissions - you didn't post the permissions for the directories, only the files in them. You need 'ls -ld'

The other errors - do those files actually exist? Do you have an example.conf in your configs directory? I don't see one in your screenshot.

[andrewtee2001]

My folder permission is as follows:-

drwxr--r--. 2 apache apache 4096 Oct 14 11:51 configs
drwxr--r--. 2 cacti apache 4096 Apr 11 2013 output

I do not have example.conf in my configs directory. I though the command creates a new map. My bad.

I will change the example.conf to some existing map and let you know. Thanks!

[andrewtee2001]

OK I have corrected my command. I am choosing an existing config file now.
MyREN.html and MyREN.png files added in the weathermap directory.

Below is my screenshot. Anything wrong here? I am still facing the issue thumbnail not created even after this.

Last resort, I will access to server owner's serve room and disable the selinux. Will update you again.

[Howie]

Did you actually have errors in the selinux audit log? I don't think that would affect the map creation, only the editing.

But if you don't see ANY lines in the cacti.log for weathermap, then something else in the cacti database is not right. There should always be a "WEATHERMAP Starting" and "WEATHERMAP STATS" line.

Hi Howie,

Appreciate if you have an diagnostics steps to share on how to check if the cacti database is workable for weathermap?
Really appreciate your on going support.

Hi Howie, I have copied the database query as follows after referring to other posts similar to thumbnail not created.
