<p>Hi David,</p>
<p><br>
</p>
<p>If you can provide a complete sample log message (redact any
sensitive log information), I'm sure we can work the filter out.</p>

I am dealing with the known Cisco bug for Excessive logging of
"vpn:vpn [INFO] device" messages in /var/log/messages file. It
is filling our ingestion cap. I have tried numerous ways to
block this from being ingested but nothing has worked(adding
filter and log). Below is my syslog-ng.conf and I am looking
for any advice to stop the "vpn:vpn [INFO] device" messages from
being sent. There are no syslog ids for this either so blocking
it from FMC also isn't working</div>
