The database is one of the most critical components, and incidents are costly, very costly.
Traditional monitoring allows you to react quickly to problems, but it only steps in after the fact. What if we could anticipate them instead?
Too often, early warning signs are ignored: blocking queries, long locks, accumulating dead rows, outdated statistics, or sudden volume changes... These underlooked indicators could have prevented incidents, lengthy investigations, and spared you a painful post-mortem 😅.

After in-depth discussions with DBAs, SREs, and developers from some of the most demanding companies, I’ll share the results of the most common problem and, more importantly, concrete solutions to detect these signals in time and act before it’s too late.
