system.run syntax?

[trikke]

Hi,

I'm having trouble with a system.run Command.
How do I "escape" the ',' ?

e.g.
zabbix_get -s servername -k "system.run[wmic service get DisplayName]" --> works

zabbix_get -s servername -k "system.run[wmic service get DisplayName,StartMode,State]" --> doesn't work because of the ',' (comma).

How can I make this work?

Tried \, already, any other suggestions?

Hi !

For me, the syntax is "system.run[command,<mode>]" with "wait (default)".

mode "StartMode or State" isn't correct mode

choice "wait" or "nowait", only correct value.

Hi Biobabar,

I'm aware that ,wait or ,nowait is a parameter to the key, my question was: how to escape a ',' in case this is part of the Command I'm trying to execute!

OK sorry :

Do you have test :

zabbix_get -s servername -k system.run["wmic service get DisplayName,StartMode,State"]

with command in quote ?

[Biobabar]

I find this syntax for this command :

system.run[wmic service where "Startmode='Auto' and state!='Running'" get DisplayName /Format:csv]

(Output as text)

a solution maybe

[trikke]

yep, tried the quotes to no avail,
The other Command is not quite what i need, sorry

Hi Patrick,

Do I understand correctly that the problem is executing zabbix_get when the key contains ','? If that is the case, which shell are you using?

Hi, Tahnx for the suggestion.
I tried with bash and ksh, both the Same Result:

zabbix-zone#bash
zabbix-zone#zabbix_get -s xxxx -k system.run["wmic service DisplayName\,Name"]
ZBX_NOTSUPPORTED
zabbix-zone#zabbix_get -s xxxx -k system.run["wmic service DisplayName,Name"]
ZBX_NOTSUPPORTED
zabbix-zone#zabbix_get -s xxxx -k "system.run[wmic service DisplayName,Name]"
ZBX_NOTSUPPORTED
zabbix-zone#zabbix_get -s xxxx -k "system.run[wmic service DisplayName\,Name]"
ZBX_NOTSUPPORTED
zabbix-zone#
zabbix-zone#
zabbix-zone#ksh
zabbix-zone#zabbix_get -s xxxx -k system.run["wmic service DisplayName\,Name"]
ZBX_NOTSUPPORTED
zabbix-zone#zabbix_get -s xxxx -k system.run["wmic service DisplayName,Name"]
ZBX_NOTSUPPORTED
zabbix-zone#zabbix_get -s xxxx -k "system.run[wmic service DisplayName,Name]"
ZBX_NOTSUPPORTED
zabbix-zone#zabbix_get -s xxxx -k "system.run[wmic service DisplayName\,Name]"
ZBX_NOTSUPPORTED
zabbix-zone#
zabbix-zone#
zabbix-zone#exit

I'm on Zabbix v1.8.3 (revision 13928) (16 August 2010)

Any other suggestion?

[Rudd]

ZBX_NOTSUPPORTED means that the key you are trying to retrieve is not supported by the agent. Not that the command you are trying to execute is failing.

Do you have "EnableRemoteCommands=1" in zabbix_agentd.conf?

Trikke,

I really don't think that what you are trying to do will work, because as Biobabar pointed out earlier, the correct syntax is "system.run[command,<mode>]" with "wait (default)".

So anything that you add after the comma will be interpreted as <mode>.

May I suggest you try "system.run[my_script]", where my_script is a small script that you are going to write. Here is a link that might be helpful, it also has example scripts. http://www.robvanderwoude.com/wmistart.php

Alternatively, google: wmi scripting

Hi MrKen,

You are and Biobabar are absolutely right that the command is "misinterpreted" and everything behind the ',' is interpreted as <mode>. I'm aware of that. ( This "behaviour" used to occure with UserParameters as well.)
I was just looking for a way to get passed this.

I already thought of the scripting to. There is just one Problem, I have to run the Command on 540 hosts and i really don't want to distribute the script to all of them.

Besides it's not just for this wmi-command but could/is helpfull for other commands using ',' as well,

Can you try:
zabbix_get -s xxxx -k "system.run['wmic service DisplayName,Name']"

and

zabbix_get -s xxxx -k system.run['wmic service DisplayName,Name']

[trikke]

Hi QIX,
tried that already, no luck!

zabbix-zone#zabbix_get -s xxx -k "system.run['wmic service DisplayName,Name']"
ZBX_NOTSUPPORTED
zabbix-zone#zabbix_get -s xxx -k system.run['wmic service DisplayName,Name']
ZBX_NOTSUPPORTED

Solution

I added a key:
system.run["ps -eo pcpu,user,args | sort -k 1 -r|head -4|awk 'NR==2 { firstRow=$0; found=0 } NR>1{ if ($1 > 15) { found=1; print $0 } } END { if (found !=1) { print firstRow } }'"]

Which works. The trick is making sure your commands are escpaed correctly. Using zabbix_get, you'd do the below:

zabbix_get -s zab01aa01p -k "system.run[\"ps -eo pcpu,user,args | sort -k 1 -r|head -14|awk 'NR==2 { firstRow=\$0; found=0 } NR>1{ if (\$1 > 5) { found=1; print \$0 } } END { if (found != 1) { print firstRow } } '\"]"

This is a fairly complicated example. Note I had to escape the quotes and $ values when using the zabbix_get command. The reason is bash interprets things differently than through the items. I use the above to get the current processes using over 15% CPU use.
