Create an item key from python script

[bekem]

Hello there,

I am using a MAX6675 for monitoring temperature and I want to create an item for this. I tried to write this 'UserParameter=max6675.pull, /usr/local/bin/max6675-1.py' to /zabbix_agentd.conf but it said 'ZBX_NOTSUPPORTED'

The attached file is python script, please take a look for helping me.

Thank you.

Did you restart agent after changing configuration?

Could you upload your zabbix_agentd.conf and you userparameter.conf?

Hi burunohl,

Please find the attachment for zabbix_agentd.

I ran zabbix_agentd -t max6675.pull and got the answer was "max6675.pull [m|ZBX_NOTSUPPORTED] [Timeout while executing a shell script.]"

[max.ch.88]

How long does your script take to be executed? The timeout for zabbix is 30 seconds maximum.

[brunohl]

max.ch.88 is correct, I guess that your script is taking longer than 30s to return

[bekem]

I ran zabbix_agentd for many times and it took exact 30s.

[brunohl]

Yeah, I guess the cance of not working is big. I would suggest you to ise the script with zabbix sender and schedule on crontab. Because I dont yhink its good practice to use 30s timeout, it can overweight your pollers.

Brunohl, can you help to write me the script?

Other thing you could do is schedule a task in your cron to run, then write the results in a txt file and then on your agent check you could just read the file created:

Cron (to run every 10 minutes):

*/10 * * * * /usr/local/bin/max6675-1.py > /tmp/result.txt

Check:

UserParameter=check_max,cat /tmp/result.txt

Of course you will always be sometime behind, but I guess it's better than timeout.

Hello

i have a different script but want to do the same thing however i get a error : "Invalid key "UserParameter=check_max,cat /tmp/dbsize.json" for item "postgre monitoorimine" on "Zabbix server": incorrect syntax near "=check_max,cat /tmp/dbsize.json"." while trying to a a key in zabbix. Any assist you could give in creating this key would be wonderful!

Hi. Could you show the output of /usr/local/bin/max6675-1.py ?

Hi, I did this and the result was not expected, I think the timeout was better more..

I think there is something in python script needs to be considered to work with zabbix...
