The VST Telescope Control Software logs continuously detailed information
about the telescope and instrument operations. Commands, telemetries, errors,
weather conditions and anything may be relevant for the instrument maintenance
and the identification of problem sources is regularly saved. All information
are recorded in textual form. These log files are often examined individually
by the observatory personnel for specific issues and for tackling problems
raised during the night. Thus, only a minimal part of the information is
normally used for daily maintenance. Nevertheless, the analysis of the archived
information collected over a long time span can be exploited to reveal useful
trends and statistics about the telescope, which would otherwise be overlooked.
Given the large size of the archive, a manual inspection and handling of the
logs is cumbersome. An automated tool with an adequate user interface has been
developed to scrape specific entries within the log files, process the data and
display it in a comprehensible way. This pipeline has been used to scan the
information collected over 5 years of telescope activity.
