Every time the trendlog data should be viewed an alarm saying" The digital signature does not match, values might not be reliable".
How can we avoid this?
In old Vista versions like Vista 4.4.x we had something called Digital signature to check that the data in the SQL database had not been tampered with.
This have been taken away in later Vista version as it slowed down and caused problems with trendlogs.
The alarm indicates that someone have done something in the SQL database and the digital signature does not match.
It is possible to turn off the Digital signature in the Vista server setup under the SQL tab and then restart the Vista server. Then Vista will not do this check and the alarm should not appear.
