Is PurgeWhenFull working?

[occhiostanco]

Hallo,
recently, I installed from scratch 1.22.3 on a new machine. I have two monitors in
"mocord" and disk gets full quickly.
I did enable (I suppose) PurgeWhenFull, but disk remains at 100%.

"run in background" and " delete all matches" are checked....

This is what I see in zmfilter.log: what is wrong ?

Thanks
Roberto

How many partitions do you have? Is it possible that your 'events' dir is on a different one to where the actual events are.

[jameswilson]

im noticing this too. purge when ful seems not to work. If i load the filter then it doesnt have automatically delete selected

[jameswilson]

definetly a problem for me ill look at the logs a zm machine just missed a break in as its hd was full

Phil, sorry for the late answer, I was busy (and ill)...
My events dir is not the default, I set it to
/videosurvey/events
( and /videosurvey/images and /videosurvey/sounds )

and yes there are two disks and many partitions involved.
See below the listing of 'df -h'

But all shoud be consistent...

Any idea?




/dev/hda1 4807056 2971868 1591004 66% /
tmpfs 241268 0 241268 0% /lib/init/rw
tmpfs 241268 0 241268 0% /dev/shm
/dev/hda2 4806936 34168 4528580 1% /home

Okay so I'm guessing that you installed the zm web pages some where in /var-/dev/hda and have a link from events to /dev/hdb2-/videosurvey?
Did you hard link or soft link?
Help clarify your setup with any information that you think might also be useful please so we can help.

Cordel, thanks for helping me...

No, I did it differently.
I have the zm web pages in
/var/www/zm
/var/www being DocumentRoot for apache.
Then I made an alias in apache

<IfModule mod_alias.c>
Alias /videosurvey/ /videosurvey/
</IfModule>

This allow apache to get events as they were in the web space.
They really are in /videosurvey (different disk, different partition)
Is this not sufficient for some zm component to find events?

This way I can see events stills from zm (i cannot generate videos, that's
a different question).

You can try:
http://www.occhiostanco.com/videosurvey ... apture.jpg
and you should see an event still....
Since directory listing is enabled in /videosurvey you can see lists of stills:
www.occhiostanco.com/videosurvey/events/3/1001/

You can see also the zm logs (aliased in apache)
www.occhiostanco.com/zmlogs

Last hint:I tried to execute directly the sql statement found in zmfilter.log
and got a syntax error near (zmDiskPercent > 80). Is tha a problem ?

Thank very much
Roberto

This is just a web shortcut to the event directory. I can see events
also the native way (clicking on them in zm), of course.

My site is
www.occhiostanco.com/zm
temporary user: roberto/roberto

If someone can help me to understand if:
- filter is not active
- filter is not selecting events
- filter cannot delete events

Thanks
Roberto

I'm not sure but you might try to change the path in options which is normaly set in regards to web root but should also accept a full path. I have not tried this yet but it should work.
If that don't work;
Return the paths back to folder in the web root.
You will need to symlink from your /var/www/zm all folders. While the change you made in apache is good for apache, it does nothing for the zm binairies.

It WORKS! Zm binaries work correctly with absolute paths, that was not the matter
(at least for filters, I have a different problem with events: I will post in a difefrent
thread)

I had 2 problems:

1) The event partition got 100% BEFORE PurgeWhenFull was set and running.
With the disk at 100% I highly suspect all is messed up.
If others will be interested I suggest to do not leave disk grows up to 100%:
-- get PurgeWhenFull running immediately with low
disk percent (3% 4%)
-- look at zmfilter.log
-- when events are getting deleted change disk percent to the desired value

2) I had ZM_OPT _FAST_DELETE enabled, and this tells zm to delete events
from db, but not from filesystem

Thanks again

I should rectify myseIf: I had a third problem, the one pointed out by Cordel

I had to make a soft link in /var/www/zm and pointing to /videosurvey (may event root
directory). All ZM binaries set up the events dir like the following:

$event_path = ZM_PATH_WEB.'/'.ZM_DIR_EVENTS + etcetera

Now Filter, view events and video generation workz
Thanks again
