<div dir="ltr"><div><div><div><div></div>Syslog-ng stores persistent options and data in syslog-ng.persist file. It contains data about drivers specified in the configuration. The drivers are identified by their "settings". In your case you have three file drivers which contain the same log file: "/var/log/abc/audit_log". Thus, the id of that driver is not unique. To provide a unique identifier for these drivers you must specify a different string in persist-name. <br><br>For example, you could add persist-name("abcaudit") to driver d_abcaudit, persist-name("abcaudit_Prio") to driver d_abcaudit_Prio and persist-name("abcaudit_IPtab") to d_abcaudit_IPtab. The key is that the string in persist-name is unique.<br><br></div>Previously, handling multiple drivers on the same thing was broken in the usage of the persist file, if I recall correctly. This persist-name option was introduced to fix the problem. So, in previous versions it was buggy.<br><br></div>BR,<br></div>kvch<br><div><div><div><div><div><div><div><div><div class="gmail_extra"><br><div class="gmail_quote">On 23 February 2017 at 16:43, David Hauck <span dir="ltr"><<a target="_blank" href="mailto:davidh@netacquire.com">davidh@netacquire.com</a>></span> wrote:<br><blockquote style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex" class="gmail_quote">Hi András,<br>

</span>Thx, I'd seen that entry prior to my email, however, it wasn't clear to me what exactly this doing. And I wasn't able to find anything in the documentation regarding the persist-name() option. Moreover, I wasn't sure if this would work with my 'destination' specification (as seen below).<br>
<br>
What exactly does "persit-name()" do? How exactly do I specifcy this for my destination specifications below? And what has changed between these two versions to now require this option?<br>
<br>
Thanks,<br>
-David<br>
