Use of undefined constant id

[ghost]

Hi,

noticed your nice script https://github.com/iar42/rt-diff via racktables mailinglist.

Unfortunately I get the following error executing php /opt/rt-diff/bin/rt-diff.php:

PHP Notice:  Use of undefined constant id - assumed 'id' in
/opt/rt-diff/bin/rt-diff.php on line 143
PHP Notice:  Use of undefined constant id - assumed 'id' in
/opt/rt-diff/bin/rt-diff.php on line 162

Beside this I get an email with RackTables changes but only after calling the script manully (Cron doesn't work even if it is set up properly under Debian8.6).

Any ideas?

Hi and thanks for the feedback.

The PHP Notice was only warning and did not seem to affect functionality but still I have applied a fix for that so please try the newest version.

About the script not sending email via cron I'm not sure what could be happening but cron most often has a limited environment like variables and such. Some ideas: If you are using the rt-diff.cron in a users crontab then you should remove the "root" part from the crontab line. Check in the rt-diff/archive directory if the script is actually updating the archive files (archive/allobj-*) and creating diff files. Check the cron log. You could add "> /tmp/rt-diff.log 2>&1" to the crontab line and check /tmp/rt-diff.log to see if you are getting any output from the script. Check the smtp servers logs if it's getting something when the script is running from cron.

Thank you so much for looking into the issue!

I've deleted /opt/rt-diff/ and installed the new zip according to your manual but unfortunately got other errors this time:

# php /opt/rt-diff/bin/rt-diff.php

The system is running with:

# uname -a

(2016-10-19) x86_64 GNU/Linux

Yes, this is most likely because you do not have the snmp package installed on the server. On Ubuntu I did "apt-get install snmp" to fix this. I guess it's the same or very similar on Debian.

Thanks alot @iar42 - apt-get install snmp did it. Initial php /opt/rt-diff/bin/rt-diff.php runs without any errors now. Unfortunately the Cron job still doesn't work. Notification is only sent after manual php /opt/rt-diff/bin/rt-diff.php... this is really strange. The server OS is an almost "vanilla" Debian8x64... just racktables, unattended-upgrades and logwatch.

Got it. Under Debian8 setting the cron job in /opt/rt-diff/rt-diff.cron doesn't work. Couldn't figure out the reason. But crontab -e with following settings work:

*/15 * * * * /usr/bin/php /opt/rt-diff/bin/rt-diff.php

Thanks alot for your support and your great script!
