Is there a way to verify that cronjobs are working properly?

http://forums.opensuse.org – I have a web application that I am trying to upgrade. Part of their upgrade process involves using a migration tool to transfer data from one version to another. This tool relies on cronjobs for it to function. According to them, the migration is not working because my cronjobs are not working properly. Is there a way to verify this? Below is what I had to paste in my crontab: MAILTO=webmaster@mymailhost.com * * * * * cd /srv/www/whiterhino/d7/periodic; /usr/bin/php -q cron.php Any ideas? (Distributions)

I am using Solaris 10, and I am adding many cronjobs to my server's crontab.

Currently I have 30 cronjobs in my crontab.

one cronjob takes 8 hours to complete ,one other cron job takes 5 hours to complete it and rest of them are ordinary cronjobs (max 30 mins they take)

As it is a production server, I am worried about server's performance.

How are they related to the performance of my server?

Is it possible to stop all cronjobs for a particular cpanel user? The cronjobs should be resumable when required later.

There are several hundred cronjobs running under this user. Only this user's cronjobs should be paused/suspended.

I'm running cronjobs on a redhat 5.X. Cronjobs are getting failed frequently so how to find the root cause

On one of my servers there are 173 [migration] processes listed in ps aux.

It has 8 processors so there are the regular 1 per processor right at the top of the list.

PID COMMAND 2 [migration/0/0] 4 [migration/0/1] 6 [migration/0/2] 8 [migration/0/3] 10 [migration/0/4] 12 [migration/0/5] 14 [migration/0/6] 16 [migration/0/7]

But then there are extras in this kind of format:

PID C

I made a mistake, I edited /etc/crontab via copy and paste. And those crontab entries are not working.

We've just moved servers, from FreeBSD to CentOS. We have around 30 cron jobs which run throughout the day.

Since moving, it seems that some cron jobs are starting but not completing. We can see they kicked off but it's like they have timed out.

No errors in the phperror.log. Cron log shows the tasks starting.

I need to build an CLI SAPI based daemon, PHP app with cronjobs support for iOS platform. We have dedicated server.

What kind of PHP environment to run this type of PHP applications?

Need to execute the following line from PHP:

$res = shell_exec('sudo sh /home/nicklas/cronjobs/make_account.sh username password');

The problem is nothing happens on execution. If i try to echo $res it comes out blank. I've tried using system() also, same result.

I'm using Ubuntu 12.04 with postfix configured as satellite system that relays outgoing mail to Gmail. For sake of example, my registered domain is example.com I want root cronjobs' error output to be mailed to my real david@example.com inbox. I have this relay working correctly.

But these root cronjobs are set by default to email to root@example.com which isn't a real email address.
