Shell Programming and Scripting

Actually I can not pass attribute "Memtable switch count" directly in script because there are many such attributes which will be passed to script and script will provide the values through the command entered in script.

For example I can pass below attributes as variable to grep
Memtable cell count
Memtable data size
Memtable off heap memory used
Memtable switch count
And many more

So next time I might be using script with different attribute

Code:

su -l zabbix -s /bin/bash -c "/opt/zabbix/cassandra.sh tests "Memtable off heap memory used""

Purpose of this is basically zabbix will be making call to this script and output data will be used for monitoring. I will be passing attributes to zabbix through its web interface and zabbix will execute this script for passed attribute.

Hope that clarifies now

Thanks for your help.

The most likely explanation is that the non root user does not have either permission or authority to run the command.

Below is the suders configuration for zabbix user.

Code:

Defaults:zabbix !requiretty
Cmnd_Alias ZABBIX_CMDS = /opt/zabbix/, /opt/zabbix/cassandra.sh, /bin/grep, /usr/bin/nodetool, /usr/bin/awk, /bin/sed
zabbix ALL = NOPASSWD: ZABBIX_CMDS

These are the commands scripts refers to. Am I missing anything here.?

Thanks,

That's how the command is parsed. The double quotes are not doing what you think.

Code:

su -l zabbix -s /bin/bash -c '/opt/zabbix/cassandra.sh tests "Memtable off heap memory used"'
