Re: Help with SNMP

Hi spinal_df,

it seems to be a Net::SNMP perl module limitation: the timeout must be between 1 and 60 seconds. It's 5 by default.

Are you really sure to need such long timeout ?

Re: Help with SNMP

That timeout is really for only one SNMP request at a time. Unless you have a very busy device which can't answer one SNMP request in a minute, this makes no sens to have a great value here.
If you mean your inventory is aborted by the agent, this is really what you want. What's really happening when you don't set timeout ?

Please, if you know you have one SNMP request which takes more than a minute, can you share more details ?

Re: Help with SNMP

Well, if I use this command:

snmpwalk -v2c -c example 192.168.15.3 (complete informations)

If I change these files for 'timeout' for 120 seconds, i have complete info.

/usr/share/fusioninventory/lib/FusionInventory/Agent/Config.pm

'timeout'                 => 120,

/usr/share/fusioninventory/lib/FusionInventory/Agent/Task/NetInventory.pm

timeout      => $params->{timeout} || 120,

I need only change parameter for accept 120 seconds for some occasions.

I would like only use fusioninventory-netinventory with 120 seconds, because I use on glpi inventory with snmp protocol about switches and anothers scripts.

Re: Help with SNMP

If a walk takes more than 2 minutes with the system command, this doesn't mean you need a greater timeout for the agent. A I said, the timeout if only for one snmp request. When you run a walk, snmpwalk makes on snmp request for each OID line from the generated walk. So the timeout for snmpwalk command is really not the same than the one for Net::SNMP perl module.
And as I said, the Net::SNMP module doesn't support a greater timeout (by snmp request again).

Have you even try to run the agent with 60 as timeout ? And in that case, do you have an error ? And if you have an error, can you report it ?
