That's why a reliable, affordable, and intuitive tool is needed to help us — and that's the purpose behind my work on Argus DBA.</p> <p>If you have any suggestions or comments, please feel free to share them, as they will be a great source of improvement.</p> <p>Discover Argus DBA at: argusdba.com and/or app.argusdba.com</p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F77v67fzmk1oozaubzlu0.jpg" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F77v67fzmk1oozaubzlu0.jpg" alt=" " width="800" height="500"></a></p> postgres monitoring postgressql dba Targino Castelo Branco Fri, 20 Mar 2026 11:56:20 +0000 https://dev.to/targinocastelobranco/quanto-tempo-leva-pra-sua-equipe-descobrir-que-o-postgresql-caiu-fk4 https://dev.to/targinocastelobranco/quanto-tempo-leva-pra-sua-equipe-descobrir-que-o-postgresql-caiu-fk4 <p>Sexta-feira, 18h. O banco de dados caiu.</p> <p>Ninguém percebeu até o suporte receber uma enxurrada de tickets. Foram 23 minutos de downtime. O custo? Difícil calcular, mas fácil sentir.</p> <p>Isso acontece mais do que deveria — e quase sempre pelo mesmo motivo: ninguém estava checando se o PostgreSQL ainda estava no ar.</p> <p>Monitorar disponibilidade não precisa ser complexo. Um check ativo a cada poucos segundos, um alerta instantâneo quando algo cai, e um histórico pra entender o que aconteceu.</p> <p>Escrevemos um post explicando o que monitorar e como automatizar isso:<br> <a href="https://argusdba.com/pt/blog/por-que-monitorar-disponibilidade-postgresql/" rel="noopener noreferrer">https://argusdba.com/pt/blog/por-que-monitorar-disponibilidade-postgresql/</a></p> postgres postgressql dba sre
