[syslog-ng] Uniqid

[Laszlo Szemere (lszemere)]

Hello,
 I do not clearly understand when you say: "but when using it in the file name, the output was presented in hexadecimal"

 It is always a good approach in an open source project to examine the code itself.
 The UNIQID macro: https://github.com/syslog-ng/syslog-ng/blob/master/lib/template/macros.c#L600
 The format_uint64_padded function: https://github.com/syslog-ng/syslog-ng/blob/master/lib/str-format.c#L136

 According to this, the UNIQID macro is ALWAYS presented as a concatenation of hexadecimal numbers, not just in case of filenames.


 Referring to the documentation: https://www.syslog-ng.com/technical-documents/doc/syslog-ng-premium-edition/6.0.18/administration-guide/20#global-use-uniqid
 The UNIQID is just the combination of the HOSTID and the RCPTID macros, which can be easily expressed in the filename parameter manually. (The RCTPID has a base10 representation.)


Note1: Since UNIQID is a globally unique identifier for each message (as long as it do not overflow), with this config ALL of your messages are going into a different file. Is this really what you want to achieve?
Note2: We usually do not recommend to use the "use-uniqid()" option for load balancing purposes, since it has an extra overhead, and load balancing usually do not requires such a precision. Usually the "second" or the "millisecond" part of the message achieve the same thing.

Best regards,
Laci

Hello People,

I'm using the uniqid in my syslog-ng.conf , but when using it in the file name, the output was presented in hexadecimal, example: "8e99d7b2 at 000000000000040b.log"

How to convert the output to decimal because we have a balancer layer to collect files ending in even numbers and another layer for odd numbers.

This is part of syslog-ng.conf: "${HOST}_${YEAR}${MONTH}${DAY}${HOUR}${MIN}${SEC}_GMT${TZ}_${UNIQID}.log"
