limited second trend lookback |

Alex told me that the "trend data is not available" message comes from the "trender" functionality not being enabled in daqd. After re-enabling it (see #6555) minute trend data was available again. However, there still seems to be an issue with second trends. When I try to retrieve second trend data from dataviewer for which minute trend data *is* available I get the following error message:
Connecting to NDS Server fb (TCP port 8088)
Connecting.... done
No data found
read(); errno=9
read(); errno=9
T0=12-04-04-02-14-29; Length=3600 (s)
No data output.
Awaiting more help from Alex...

It looks like this is actually just a limit of how long we're saving the second trends, which is just not that long. I'll look into extending the second trend look-back. |
