I have made the following entry in the Syslog Message Pattern field in Syslog Viewer on the NPM Syslog page.
NOT (*Unexpected*). All messages disappear, not just the ones with "Unexpected" inside their text. If I just use *Unexpected* then all I get are the messages that say "Unexpected". Why are all messages disappearing instead of just the ones with the targeted text? What pattern filter should I use?
