System.run key shows too many parameter

[iftitutul]

In zabbix, Already enabled remote command. but item shows with error.
item key: system.run[ps -eo pid,ppid,user,cmd,%mem,%cpu --sort=-%cpu | head -n 6]
TypeZabbix Agent)
It shows not supported with message- Too many parameters.
how can solve it?

Hi,
Which version of zabbix are you using?
Note that if you are monitoring host over proxy remote commands are supported only on 3.4.x

and try to put you command in quotes:
system.run["ps -eo pid,ppid,user,cmd,%mem,%cpu --sort=-%cpu | head -n 6"]

[iftitutul]

Zabbix verison-3.4.
Thanks. it's working

[Pitons]

Good to hear!

If your command has commas always use quotes
as zabbix also interprets comma and expects other parameters.

Thanks Pitons.
But how can this item added in action? Because when mail sending it can also shows item result

Thanks Pitons.

Do you mean trigger some action on some values and then send result by mail?

Please explain scenario what do you want to achieve?

[iftitutul]

I don't send any trigger of this item: system.run["ps -eo pid,ppid,user,cmd,%mem,%cpu --sort=-%cpu | head -n 6"].

"Do you mean trigger some action on some values and then send result by mail?"
-Yes. Any template: os linux related it shows the item values for this item:system.run["ps -eo pid,ppid,user,cmd,%mem,%cpu --sort=-%cpu | head -n 6"].
I think you got my point.

so is it ok if I add the below item in action mail?
host:system.run["ps -eo pid,ppid,user,cmd,%mem,%cpu --sort=-%cpu | head -n 6"].

[Pitons]

Yes, sure you can do that, but in basis this is wrong.
use: {host:system.run["ps -eo pid,ppid,user,cmd,%mem,%cpu --sort=-%cpu | head -n 6"].last()}

Why it's wrong:
1. Use zabbix agent to collect metrics try to avoid using remote commands, it's a security risk and you are populating database with unnecessary information and load.
More about it :
2. Create items to monitor specific processes and corresponding triggers for them, so you get specific alerts and you know exactly where the problem is.
3. Go further - create remote commands, for example: to restart the service if its memory/cpu usage too high.
4. Avoid spamming yourself and others with unneeded info.

But that's just my thoughts you are free to do whatever you wan't.

[iftitutul]

Thanks for your nice info.
"3. Go further - create remote commands, for example: to restart the service if its memory/cpu usage too high." - is remote command executed, is it possible to show zabbix side [mail/history].

Suppose, memory/cpu usage too high it will excuted command 'system.run["ps -eo pid,ppid,user,cmd,%mem,%cpu --sort=-%cpu | head -n 6"]'.
so what is the output of this result? How can enlisted this result into mail ?
