Restart the agent by going to the Agents page (under Inventory), finding the vc-mysql-metrics or vc-pgsql-metrics agent for that database, and clicking restart: You should begin to see metrics for your Google databases within a few minutes. If you want to reset your statistics in the performance_schema, you can run the command below: mysql> TRUNCATE TABLE performance_schema.events_statements_summary_by_digest; Some Helpful query examples.

Earlier this spring, we upgraded our database cluster to MySQL 5.6.Along with many other improvements, 5.6 added some exciting new features to the performance schema.. MySQL’s performance schema is a set of tables that MySQL maintains to track internal performance metrics. There are a bunch of advantages to using timeseries data for monitoring * We can also look back through history. Essentially I wrote some custom Lua code that attaches to proxy. It’s a scenario where you don’t need 100% the exactly same traffic. Performance Schema tables are considered local to the server, and changes to them are not replicated or written to the binary log.

Next, find the Project ID and Instance ID. My intention when choosing to use pt-query-digest was to show how close to reality (and by reality i mean: “the traffic captured by the slow log file”) was the traffic collected through performance schema. likely that pg_stat_statements does not exist on the database the DPM user is connected Using this I have been able to save 60m queries per day, moved 40m connections off a master onto the slaves, and found out the reasons why the DB was dragging the site down in high load, and stopped it from happening.

We used to try and do this with a nagios plugin, but the plugin only looked at the current value of the counters. If you opt to create a custom policy, it will need to include the following: Note for proxy users: If you have installed the agent on an EC2 instance and are providing access to CloudWatch through an IAM role AND are using a proxy set via a system environment variable, you will need to exclude requests to the AWS metadata service. If providing credentials using the /root/.aws/credentials file, its contents look like this: (The file must be in /root/, as that is the user which runs the DPM software.). Monitoring using the performance_schema is also required when monitoring self-managed databases that use encrypted connections or Unix sockets.
