[Solved] 0.8.8h to 1.0.4 CMDPHP PHP ERROR WARNING Backtrace

[aletatone]

Hi All,

I upgraded from 0.8.8h to 1.0.4 in Centos 7 Server.
After upgrade everything works fine (just some tuning in my.cfg file) and all graphs looks ok,
but when I check cacti log i see these error messages:

CMDPHP PHP ERROR WARNING Backtrace: (/poller_maintenance.php: 138 realtime_purge_cache)(/poller_maintenance.php: 160 unlink)(CactiErrorHandler)(/lib/functions.php: 4259 cacti_debug_backtrace)

Before upgrade I had realtime plugin that now is disappeared (i don't know if it could be part of the problem)

Any Idea?

Thanks
Ale

I found the solution to my problem.

Cacti was trying to delete files into /tmp/ directory because it was set as cache directory for realtime but it did not have permission to do it.
Into database i found:

MariaDB [cacti]> select * from settings where value like "%tmp%";
+---------------------+-------+
| name | value |
+---------------------+-------+
| realtime_cache_path | /tmp |
+---------------------+-------+

then I create a new directory:

/tmp/realtime_cache
chown cacti.cacti /tmp/realtime_cache
chmod 775 /tmp/realtime_cache

and then change parameter in cacti database:

MariaDB [cacti]> update settings set value = '/tmp/realtime_cache' where name = 'realtime_cache_path';
Query OK, 1 row affected (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 0

MariaDB [cacti]> select * from settings where value like "%tmp%";
+---------------------+---------------------+
| name | value |

1 row in set (0.01 sec)
