Fully managed PostgreSQL hosting at ScaleGrid provides Activity Stats for your PostgreSQL cluster deployment. Activity Stats include all of the important metrics you need to know about your PostgreSQL server.
- Log into the ScaleGrid console.
- Go to your PostgreSQL cluster details page.
- Click on the Activity Stats tab at the top.
- Review your PostgreSQL activity metrics!
By default, your Activity Stats presents data for all of your PostgreSQL databases. You can customize which database to view stats for from the dropdown list at the top, and select whether to show table data.
Click the Refresh button in the upper right to refresh your data, and download your Activity Stats report through the Download PDF button.
Total number of tables.
Total number of indexes.
Size of database on disk.
Largest PostgreSQL tables by size on disk.
Largest indices by size on disk.
Tables in this deployment with most dead rows. Higher number of dead rows can impact performance, and indicate bloated tables.
An estimate of table bloat computed from usage and size statistics. This is an estimate only - please contact [email protected] to calculate your actual bloat metrics.
An estimate of the bloat on your BTree Indexes computed from usage and size statistics. This is an estimate only - please contact [email protected] to calculate your actual bloat metrics.
Most frequently vacuumed tables in this deployment. These are the tables where auto-vacuum has been called most often. This typically means there is a lot of updates/deletes going on in this table.
Largest tables in this deployment, by number of rows fetched from database.
Tables with the most rows updated. This graph shows how many rows were updated in the normal manner (number of updates) vs. how many updated rows took advantage of Heap-Only-Update (number of HOT updates). HOT updates are designed to be faster, but work only if no indexed column is being updated. If your total updates are very high for a table, and very few of them are HOT updates, your update performance will degrade.
Top tables by select activity.
Top indexes by scan activity.
Top tables by insert activity.
Top tables by update activity.
Top tables by cache effectiveness. This graph shows the ratio of (Blocks read from Buffer Cache) to (Total Blocks Read). If this ratio is very low, your database performance might degrade. Using a machine with more RAM would help improve performance.
Top tables, by number of sequential scans initiated. If the number of sequential scans is much higher than number of index scans, it might indicate inefficient indexing on the table.
