Magento Enterprise Ver : 1.13
My cron scheduler has stopped suddenly.
When i checked cron_scheduler table i am not getting any entry there after 16th Jan.
I have tried a lot but unable to find any lead regarding what would have stopped it.
Its not scheduling jobs after running the cron.php manually also.
Hence please suggest if any one knows where to look or any way to track down the problem.
Refrence : cron.sh is having 777 permission
Run $ crontab -e on your server and check your cron configuration.
You can add MAILTO=your.email#example.com at the beginning of the file to send an email for every cron that is fired.
You'll probably get the error message there.

I have installed cacti php in my ubuntu 14.04.
Cacti create rrd file and periodically update it after each 5 mins.
sample rrd file like /var/lib/cacti/rra/localhost_hdd_free_14.rrd
I need some help.
Now I want to know this script path that create and update this rrd file in
background.Means, I want to know where this script is located in cacti
environment.
This peridic update is continue even I stop the apache server.
It means it running as cron job.
But when I run this command "crontab -e -u root"
it says that there is no cron job for this user.
I want to find out how the data is collected across network using snmp
to create graph for different device.
Please help me to find out this cron scipt.
Here what I have find.
You can get the list of cronjob running under Linux Ubuntu in following directory.
/etc/cron.d/ directory.
Under this directory,you wll find the all cronjob running for cacti.You can edit desired file if you have permission.Then do the change what you want like changing interval for cron,changing target file that you want run.
We recently did a large server migration, and for some reason cron isn't working as expected on the new system. Some cron scripts are running as normal but others don't seem to be executing at all.
If I look at the old server and tail the cron log /var/log/cron, I can see cron scripts executed as they should.
On the new server, none of the user cron execution shows up in the log. I can see general cron messages for user accounts, and I can see ROOT crons running, but no information on user crons other than general messages such as LIST, REPLACE, etc.
I've checked permissions on the files being executed. Some of the scripts log to files or send emails, so I know that some are running and some aren't. I've also verified the cron jobs are located in /var/spool/cron.
Most of these are php scripts, and the only change we made on this server vs. the other one is running apache using mpm-itk. This shouldn't be the problem though since file permissions weren't changed and shell is running php cli.
Would be a lot of help if I could verify the scripts are being executed. No errors in apache or other logs that I can find. Any suggestions would be appreciated.
I've always used mysql events for scheduled tasks but my hosting doesn't allow the event scheduler to run. I've had to make the switch to cron jobs and I think I'm very close to getting them working. Spent hours reading tutorials and testing but no luck.
I have a cron job that I want to run every minute, here's what it runs:
/web/cgi-bin/php5 /public_html/velrania.com/cron.php > /dev/null 2>&1
The php file location is fine, the dev/null part is there to prevent email notifications (unless I've been misinformed) so I think it is the first part which executes php
I've tried changing the path to "/usr/local/bin/php -q" as directed by https://support.godaddy.com/help/article/3483/what-is-a-cron-job?countrysite=uk but that didn't work.
Ha, I'm stupid.
/public_html/velrania.com/cron.php
needed to be
/home/USERNAME/public_html/velrania.com/cron.php
I have a php file which pulls some data from external API's, and I want to schedule it to do so every few hours (or every few days). Some googleing led me to "scheduled tasks", but it seems I need to be running my own server to do it?
So far, all the PHP and MySQL I've done have been very simple form-filling, so I'm a little lost. Do I need to turn a computer into a server to do this, or should I look into hosts that allow you to run scripts? I'm not exactly sure what I'm looking for.
Side-question: how would I be able to prevent someone else from running the PHP script (therefor making tons of API calls)?
How are you running the script now? Windows or Linux? Linux is a no-brainer with cron: on a PHP-enabled server simply drop the PHP script somewhere, edit the crontab and away you go!
Ex. for every 2 hours
0 */2 * * * /usr/local/bin/php /path/to/script.php
Edit Re: Mac
launchd is apparently the preferred method to run scheduled tasks but I understand that OS X has cron capabilities as well being a UNIX derivative.
If you have a reasonably busy web server, you can simply check every time how long it has been since the last time you ran the script. If more than two hours, run it.
Just make sure to update the time and run the script atomically so you don't launch several copies of the script. You can do this with a file that contains the last time the script was run that you lock while you check and update it.
cronjobs are made for it... You can check the Cron Jobs in cpanel..

I've been running a daily cron job for a few months and it was working fine.
The cron job runs a php script that does a database action then mails my email address with the results.
Suddenly a few days ago, when the script ran, the database action stopped working, but it would send me the email. I changed the php script to send a different email, but it still sends me the old one.
I can't seem to get any new scripts to run and when I set up an email address for the cron job to run it doesn't send one.
Any thought as to how I can get this back on track?
More information:
I use a linux OS cPanel.
I've used the following commands.
/usr/bin/php -f /home/[user]/public_html/[path to script]
/usr/bin/php -q /home/[user]/public_html/[path to script]
/usr/local/bin/php -f /home/[user]/public_html/[path to script]
/usr/local/bin/php -q /home/[user]/public_html/[path to script]
PHP says that the path to PHP is /usr/bin/php however, it used to work with the local part in there.
#DampeS8N- I'd rather not. The PHP script just includes a few sql commands and a mail function. It works fine without any errors when visited by browser.
#Paul- That is what I am inclined to believe. I think the Cron Daemon is stuck somehow. When I try to add new cron jobs, they don't register as going off, and it won't send emails to my email address when a cron should go off.
I am a complete newbie to cron. I access cron jobs in my cPanel X. I'm pretty sure I don't use crontab. Detailed instructions for any actions you'd like me to take would be great.
Well, I wound up contacting my hosting support. Turns out the domain was moved to a new server and the cron jobs were still running on the old one.
