LoriotPro has extended the LUA sripting language by providing its own LUA libraries. The new functions provided are dedicated to the creation of monitoring and SNMP automation application.
Refers to the request for comment dor more details about the syslog message format RFC 3164
Syntax
value = lp.SendSyslog('ip_server','buffer');
Description
The lp.SendSyslog LUA function sends a Syslog Message to a syslog server.
Parameters
‘ip_server’ The IP address of the remote syslog sever.
'buffer' The text of the message starting with the priority number between <> sign.
The priority value is calculated by multiplying the Facility value by 8 and adding the Severity value.
| Table of Facility | Table of Severity | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
|
Example :
With a Facility type of “local use 0” value 16 and a Severity “Critical” value 2
then : (16*8) + 2 = 130
Syntax : lp.SendSyslog(" 127.0.0.1 ", "<130> texte du message")
Return Values
value : equal 1 if sent
Return nil if an error occurs
Example
Example of syslog sent to the local LoriotPro embedded Syslog server (listening on the standard syslog UDP port 514) .
for i=0,200 do
a=string.format("<167> test %i",i);
lp.SendSyslog("127.0.0.1",a);
end
Other example that generate all the syslog messages possibilities
for facility=0,23 do
for severity=0,7 do
priority = (facility*8)+severity
syslogmessage = string.format("<%i> test %i:%i",priority,facility,severity)
lp.Trace(syslogmessage,"\n")
lp.SendSyslog("127.0.0.1",syslogmessage)
end
end
Result of the script in the Syslog viewer.
