Hello, Solarwinds has a database for Syslog. In this DB there are a HOSTNAME_UNICODE column which is used to show Syslog Hostname under Syslog web page.
Is uses DNS to fill this column, and if DNS does not work it fills it with IP address, but it's not regularly updated.
We changed hostnames of our devices but Syslog kept showing old ones. No DNS is configured.
I found a couples ways to fix this.
You can:
1) Update Syslog.Hostname_UNICODE field to match Node.Caption or Node.Sysname using SQL update statement.
Or
2) Using Syslog Viewer application from your Solarwinds server you can define which columns to show on the syslog web page, and you may replace Source Hostname (from Syslog.Hostname) with Node Name (From Nodes.Caption).
