Changing external command timeout

[antoniogmyo]

Hi,

Sorry if this is documented somewhere, but I couldn´t find it. Is there a way to modify the external commands time out?.

Thanks in advance.

Hi:

Yes, in zabbix_server.conf you can find a section like this

### Option: Timeout
#       Specifies how long we wait for agent, SNMP device or external check (in seconds).
#
# Mandatory: no
# Range: 1-30
# Default:
# Timeout=3

Cheers.

I forgot to mention I´m running zabbix 1.6.7. In my zabbix_server.conf file I just got this section:


# Specifies how long we wait for agent response (in sec)
# Must be between 1 and 30
Timeout=30


does this apply to external commands too?

Thanks in advance.

Sorry, but for that version I don't know if "TimeOut" applies to external checks too..

I know that this works fine for Zabbix 1.8.2 and 1.8.3

Cheers.

Yes, it does.
We use a lot of external checks, some of them may sometime need more than 20 seconds to complete.
We have used Timeout=30 parameter on our Zabbix server since 1.6.2 (now upgraded to 1.8.3) without problem.

Thanks both for the responses.

Getting deeper into this....to rise a bit the max timeout...let´s say to 60 seconds, should I modify source code and recompile?. Any clue where to look for?. I know it is a bit too much, and it would be nice if I could separate external commands timeout from agent timeout, but by now we need to set it up to 60 seconds at least.

Cheers.

I think that you have to edit source code.. looking into source code at 1.8.2 I am able to find these occurrences:

src/zabbix_proxy/proxy.c: {"Timeout",&CONFIG_TIMEOUT,0,TYPE_INT,PARM_OPT,1,3 0},
src/zabbix_server/server.c: {"Timeout",&CONFIG_TIMEOUT,0,TYPE_INT,PARM_OPT,1,3 0},
src/zabbix_agent/zbxconf.c: {"Timeout", &CONFIG_TIMEOUT, 0,TYPE_INT, PARM_OPT, 1,30},
src/zabbix_agent/zabbix_agent.c: {"Timeout",&CONFIG_TIMEOUT,0,TYPE_INT,PARM_OPT,1,3 0},

I think you should change those "30" (max allowed value) for whatever you want... recompile source code and try...

I don't know if you can have server timeout distinct from agent timeout .. you should try.. if zabbix_agent or zabbix_server refuses to start, you'll need to add more source code in order to allow them to have different values.

Hi,

It seems that it worked fine. Modifying the server.c and compiling again with no problems.

Not sure how to check in the logs how long takes the script to run, I´ll modify script to log itself start and ending time.

Thanks guys for the help.

Best regards.

As a rule of thumb, try not to increase timeout value more than 10 sec. unless you have no option.Why? Becase you can lock your pollers if you have tons of script that timeout regullary.

But, if you are going to use high timeout value then try to overprovision the number of pollers in Zabbix configuration file and check regularly Zabbix health statistic.

You can increase timeout over 30 sec by changing “Timeout” in source file src/zabbix_server/server.c and recompiling Zabbix server.
