Installing common statistics packages

There are several common data-gathering tools, and each of them has its own place. Several are already installed for extremely basic information, but for the purposes of this chapter, we need more depth.

For instance, we may want to know the exact distribution of CPU resources, aggregate views of memory paging volume, or disk I/O utilization. For more in-depth needs, we could analyze specific processes for storage interaction or resource locks. If we weren't watching at the exact time a problem occurred, we might want a historical record of various server performance metrics.

In order to have all these capabilities, we must first install the requisite tools. We might find it quite shocking that these tools are not installed by default, considering their role in server administration.

Shaun Thomas

Shaun M. Thomas has been working with PostgreSQL since late 2000. He is a frequent contributor to the PostgreSQL Performance and General mailing lists, assisting other DBAs with the knowledge he's gained over the years. In 2011 and 2012, he gave presentations at the Postgres Open conference on topics such as handling extreme throughput, high availability, server redundancy, and failover techniques. Most recently, he has contributed the Shard Manager extension and the walctl WAL management suite. Currently, he serves as the database architect at PEAK6 Investments, where he develops standard operating procedure (SOP) guidelines to facilitate reliable server architecture among many other tasks. Many of the techniques used in this book were developed specifically for this extreme environment. He believes that PostgreSQL has a stupendous future ahead, and he can't wait to see the advancements subsequent versions will bring. https://www.linkedin.com/in/bonesmoses
