1. Change Cacti log level to HIGH, or DEBUG.
2. run `php -q poller_output_empty.php`.
3. If the table problem solves, RRD should be processed normaly which shows GREEN in log.

cacti: fix rrd update problem

http://www.cacti.net/downloads/docs/html/scripts.html

if rrd stops updating, then:

1. create new data sources to replace the old ones from graphs, then delete the old rrd files.
2. restart httpd, and run cli/ scripts to poller_output_empty or rebuild_pollor_cache.
3. reduce system usage by adjusting polling interval in cron and settings, from 1min to 5min.
4. disable unused data sources to lower system usage.
5. check cacti log in utilities to make sure everything is green!!

@giozzz, the same thing applies to you, this probably only occurs with certain nodes. Could you check the node and make sure that all the files actually exist (in the database "files" table) when viewing/editing those nodes?

Thanks for your response, I've checked right now, and it was one picture missing in the ddblock I have on front page. Sorry for bothering you for nothing and thanks again!

drupal: Flashvideo fix

http://www.comptoncoms.com/wordpress/2011/04/drupal-flashvideo-fix-april-2011/

FFmpeg has been versioning just as Drupal has, so the default command in the Flashvideo > Content Type Setting > FFMPEG settings is likely wrong. If you are using a recent version of FFmpeg you may need to change the command line to replace “mp3” with “libmp3lame”. At any rate you will need to understand the commands for FFmpeg to make the conversion do what you want.

Content type is the second problem. In the original any number of videos could be placed on the node to include the original video and the converted flash version. But that process no longer seems to work. The original upload video content type needs to have under the “display fields “ the type excluded.

Last is the player problem. The whole time that Flashvideo has been versioning, the media player has been drastically changing as well. With a whole lot of work you can get the original Flowplayer to work with Flashvideo, but then you will not have the poster image only a black screen. Even worse is that if you turn on Jquery with SWF Tools, your Views module no longer works. So I strongly recommend the JW_player. You will need to install the jwplayermodule, but it is worth the effort and the added cost. The player retails for $89. With JWplayer 5.5 you can insert video into any content type. The instructions are in a PDF for Drupal with the download. It is a very nifty solution that uses file attachment. After you have installed the JWplayer module you will need to put a copy of player.swf from the JWplayer directory into the directory where the videos are output and rename it “Player.swf”.
