[ZendTo] Re: Cron errors

[Seth Turner]

Thank you for the help. I am still learning, but consider myself a beginner to intermediate Linux admin. I was able to get the virtual appliance running with only one or two snags. I also put Webmin on the machine to more easily manage it. Out of curiosity, do you have plans on creating a new virtual server on Ubuntu 12.x LTS?

Regards,
Seth

Hi Jules,

Here is the cron file:

# /etc/cron.d/zendto: crontab fragment for zendto
5 0 * * * root /usr/bin/php /opt/zendto/sbin/cleanup.php /opt/zendto/config/preferences.php
2 10 * * * root /usr/bin/php /opt/zendto/sbin/rrdInit.php /opt/zendto/config/preferences.php
2 12 * * * root /usr/bin/php /opt/zendto/sbin/rrdUpdate.php /opt/zendto/config/preferences.php

Are you saying to change it to:

# /etc/cron.d/zendto: crontab fragment for zendto
5 0 * * * root /usr/bin/php /opt/zendto/sbin/cleanup.php /opt/zendto/config/preferences.php
2 10 * * * root /usr/bin/php /opt/zendto/sbin/rrdInit.php /dev/null
2 12 * * * root /usr/bin/php /opt/zendto/sbin/rrdUpdate.php /dev/null
No. Sorry, I clearly misunderstood how much Unix/linux sysadmin you know. :-)
Just add this onto the end of each line:
    >/dev/null 2>&1

You'll then need to do a "service crond reload" for it to re-read the crontab files, or else your changes won't be noticed.

Jules.



Thank you,
Seth

Hello everyone,

First, let me express my thanks to Jules. We are new to Zend, but have our virtual server running in production and love it. I do, however, see the following two error emails from cron processes.

That's rrdgraph generating the usage stats images. Just send the output of the cron job (it's in /etc/cron.d) to /dev/null.








And



"7

/usr/bin/rrdtool update /var/zendto/rrd/zendto.rrd 1354770000:1:1:35838.3



ERROR: /var/zendto/rrd/zendto.rrd: illegal attempt to update using time 1354770000 when last update time is 1354770000 (minimum one second step)"
Every night it tries to recreate all the stats data it can from the entire month's worth of data available to it, in case your RRD stats file gets deleted or corrupted by mistake. But if the data is intact and okay, rrdtool complains when it tries to overwrite the old data in the file.

Again, this is quite harmless and you can just send the cron job output to /dev/null.

Jules.








Any suggestions on a fix?



Regards,

Seth
