These metrics are included for any Heroku Postgres server that has a PgBouncer pooler attachment. For an estimate of the total amount of memory available to your server, add sample#memory-free and sample#memory-cached together. The operating system is designed to maximize the amount of memory it utilizes for its page cache, but can sometimes release that memory if an application requests it.
#Heroku postgresql gui client free
sample#memory-free: Amount of free memory available in kB.sample#memory-total: Total amount of server memory available.sample#read-iops and sample#write-iops: Number of read or write operations in I/O sizes of 16KB blocks.For more information see the burstable performance section in the technical characteristic article. For databases that have burstable performance, a baseline load average is guaranteed. A load-avg of 1.0 indicates that, on average, processes were requesting CPU resources for 100% of the timespan. sample#load-avg-1m, sample#load-avg-5m and sample#load-avg-15m: The average system load over a period of 1 minute, 5 minutes and 15 minutes, divided by the number of available CPUs.For multi-tenant plans, the metrics include other databases running on the shared server, and may be misleading when diagnosing database performance. These metrics come directly from the server operating system. This metric is only published for follower databases. Replication is asynchronous so a number greater than zero may not indicate an issue, however an increasing value deserves investigation.

If your table hit rate is consistently less than 0.99, you may need to upgrade your database plan for more RAM. Heroku recommends a value of 0.99 or greater if possible. sample#table-cache-hit-rate: Ratio of table lookups served from shared buffer cache, rounded to five decimal points.If your index hit rate is consistently less than 0.99, you should investigate your Expensive Queries or you may need to upgrade your database plan for more RAM. sample#index-cache-hit-rate: Ratio of index lookups served from shared buffer cache, rounded to five decimal points.sample#current_transaction: The current transaction ID, which can be used to track writes over time.If many connections are waiting, this can be a sign of mishandled database concurrency. sample#waiting-connections: Number of connections waiting on a lock to be acquired.sample#active-connections: The number of connections established on the database.sample#tables: The number of tables in the database.Table and index data on disk, including database bloat. sample#db_size: The number of bytes contained in the database.They are the same for single-tenant and multitenant database plans.
These attributes apply to a particular database. The log line’s timestamp is the time at which the measurements were taken.addon: The database addon name that the measurements relate to (e.g.source: The database attachment name that the measurements relate to (e.g.The following attributes appear in application logs for all standard and premium tier databases. Heroku Postgres Metrics which appear via heroku-postgres are separate from standard alerts emitted from Postgres itself which appear for all applications via postgres.
