Hi Ron,

If you're referring to the history files, it's possible but will require some manual effort.

These are actually simple text files in your $XYMONVAR directory and the offending line can be removed with your favorite text editing tool. The only sticking point is that these do not have a final newline at the end, and this is used when backscanning for time calculations as a marker, so it's important to make sure that this format is generated properly. You can do a live reload of the history page (which reads that file in on each CGI hit) to confirm that no syntax errors are present in a modified version. Usually this manifests by garbled date calculations or missing event ranges.

If you're referring to the "current status display" and not a history log, in theory that should get replaced by the next incoming message just fine. xymond doesn't really care about the host's localtime or epochtime; xymond_client only uses it for the "clock skew" RRD.

If there are RRD display issues, that will be quite a bit trickier. IIRC, the process involves exporting data sets and reimporting them using rrdtool similar to when you need to "de-spike" an erroneous data value, but I've never actually done it myself.
