SNMP protocol in Logic Machine

[Carlos Padilla]

Good guys, I told them that I have a problem with the request of the OID information of the UPS and that the code works for me, but after several hours, the code stops working and I have to disable and enable the resident function again so that the data can be updated, but after several hours again I can not obtain the values. I look at the error log and the following appears:

Resident script: 16: netsnmp: Unknown host (192.168.0.114) stack traceback: [C]: in function 'assert'
Resident script: 16: netsnmp: Unknown host (192.168.0.111) stack traceback:
  [C]: in function 'assert'

The code is the following:

Code:

--Abrir una sesión con snmp
require "snmp"

local mib, err = snmp.mib.load('/home/ftp/snmp/Mikrotik.mib')
if not mib then
  log('Failed to load mib: ' .. err)
end


ups1, err = snmp.open{
 version = snmp.SNMPv1,
 community = "tekneoCO",
 port = 161,
 peer = "192.168.0.111",
}
assert(ups1, err)

I must clarify that I have the UPS are connected to the network, the connection has not fallen and I have installed the two necessary SNMP packages and I do not have any MIB file (either Mikrotik or UPS) loaded, since the UPS that I am using does not they have a single MIB file, since one information is given to me by a MIB that I found and another one is given to me by another MIB and I did not use the code that the admin indicated after, because the current one seemed more comfortable to edit, besides that I had it done. Currently I ask the variables to 4 UPS, the first question is by resident code at 20 seconds, the second at 30 seconds, 40 and 50 seconds respectively. Thank you and I will be attentive to your comments.
