Animating Weathermap

[bboy8012]

All need a little help with the cron/scripting part of animating it. I would like to do daily animations and have the files deleted every night at midnight, but before deleting create the animation and save it to another folder I have modified this script:

Code: Select all

#!/bin/sh

SRC_MAP="/usr/share/cacti/plugins/weathermap/output/weathermap_1.png"
HISTORY_DIR="/usr/share/cacti/plugins/weathermap/history"

DATE=`date '+%y%m%d%H%M'`
cp $SRC_MAP $HISTORY_DIR/map_$DATE.png
find $HISTORY_DIR -name '*.png' -mtime +1 -type f -exec rm {} \;

and pieced this one:

Code: Select all

#!/bin/sh

HISTORY_DIR="/usr/share/cacti/plugins/weathermap/history"
ANIMATION_DIR="/usr/share/cacti/plugins/weathermap/animation"

DATE=`date '+%y%m%d'`

convert $HISTORY_DIR/*.png $ANIMATION_DIR/$DATE.mpg

with my cron for gathering images set to:

Code: Select all

*/1 * * * *  /usr/share/cacti/plugins/weathermap/copy-frames.sh

cron to create animation at midnight everynight and store:

Code: Select all

0 0 * * * /usr/share/cacti/plugins/weathermap/create-animation.sh

Is this correct? Thanks

Looks about right, except that

Code: Select all

SRC_MAP="/usr/share/cacti/plugins/weathermap/output/weathermap_1.png"

will be a filename with a long hashcode in it, unless you are using a really old version of weathermap.

Also, you may want to check into ffmpeg for video encoding - you get more modern options, including H264 avi... I believe it requires the image files to be sequentially numbered though.

A note for when I finally finish it - this functionality (apart from the animation creation) is built into the poller for the next release, where it's called 'archiving'. I want to add some UI so that you could 'rewind' from inside the cacti UI to see a previous point in time.

Cant wait for that release. Thanks for all your help and hard work

Yes future is always exciting with Howie, however in a mean time here is a working script that have been posted here previously:
ffmpeg is required install on the server..
I use this script, and it works perfectly for me. I get 48hr mp4 1080p video file that is linked directly from the map.
Anyone who views the map can download and play the video.
