Install pghero on centos 7 – A performance dashboard for Postgres
In this tutorial I will show you how to install pghero on centos 7.
A performance dashboard for Postgres – health checks, suggested indexes, and more. PgHero 2.0 provides, even more, insight into your database performance with two additional features: query details and space stats.
PgHero makes it easy to see the most time-consuming queries during a given time period, but it’s hard to follow an individual query’s performance over time. When you run into issues, it’s not always easy to uncover what happened. Are the top queries during an incident consistently the most time-consuming, or are they new? Did the number of calls increase or was it the average time?
