and analyze system performance problems you can use gemini in databases assistance to help you observe and troubleshoot your cloud sql for mysql resources for more information see observe and troubleshoot with gemini assistance view the system insights dashboard to view the system insights dashboard do the following in the google cloud console go to the cloud sql instances page go to cloud sql instances click the name of an instance select the system insights tab from the sql navigation panel on the left the system insights dashboard opens figure 1 dashboard image showing events timeline and summary cards the system insights dashboard shows the following information your instance details events timeline shows the system events in a chronological order this information helps you evaluate the impact of system events on the health and performance of the instance summary cards provide an overview of the instance health and performance by displaying the latest and aggregated values for the cpu utilization disk utilization and log errors metrics metrics charts show the information about the operating system and database metrics that help you gain insight into several issues such as throughput latency and cost the dashboard offers the following high level options to create a customized dashboard click customize dashboard to keep the dashboard up to date enable the auto refresh option when you enable auto refresh the dashboard data updates every minute this feature isn t compatible with customized time periods the time selector shows 1 day selected by default to change the period select one of the other predefined periods or click custom and define a start and end time data is available for the last 30 days to create an absolute link to the dashboard click the copy link button you can share this link with other cloud sql users who have the same permissions to create an alert for a specific event click notifications notification to display specific alerts click annotations summary cards the following table describes the summary cards displayed at the top of the system insights dashboard these cards provide a brief overview of the instance s health and performance during the chosen time period summary card description cpu utilization p50 the p50 cpu utilization values cpu utilization p99 the p99 cpu utilization values disk utilization the latest disk utilization value log errors the number of errors that were logged metrics charts the toolbar on each chart card provides the following set of standard options to view metric values for a

table describes the cloud sql metrics that appear by default on the cloud sql system insights dashboard note cloud sql for mysql instances with more than 500 databases report a single aggregated value for database metrics metric name and type description query latency dbinsights googleapis com aggregate latencies the aggregated query latency distribution by p99 p95 and p50 per user and database only available for instances with query insights enabled database load per database user client address dbinsights googleapis com aggregate execution_time the accumulated query execution time per database user or client address this is the sum of cpu time i o wait time lock wait time process context switch and scheduling for all processes involved in query execution only available for instances with query insights enabled cpu utilization cloudsql googleapis com database cpu utilization the current cpu utilization represented as a percentage of the reserved cpu that s currently in use mysql connections cloudsql googleapis com database network connections the number of connections held by the database instance ingress egress bytes cloudsql googleapis com database network received_bytes_count cloudsql googleapis com database network sent_bytes_count the network traffic in terms of the number of ingress bytes bytes received and egress bytes bytes sent to and from the instance respectively memory components cloudsql googleapis com database memory components the memory components available to the database as usage cache and free memory the value for each memory component is calculated as the percentage of the total memory available to the database mysql queries cloudsql googleapis com database mysql queries the number of statements executed by the server this includes statements executed within stored programs such as stored procedures and functions mysql questions cloudsql googleapis com database mysql questions the number of statements executed by the server this includes only the statements sent to the server by the clients and not the statements executed within stored programs mysql network traffic cloudsql googleapis com database mysql received_bytes_count cloudsql googleapis com database mysql sent_bytes_count the number of bytes received from and sent to the clients innodb pages innodb dirty pages cloudsql googleapis com database mysql innodb_buffer_pool_pages_dirty innodb free pages cloudsql googleapis com database mysql innodb_buffer_pool_pages_free innodb total pages cloudsql googleapis com database mysql innodb_buffer_pool_pages_total the number of dirty free and total pages in the innodb buffer pool a dirty page in the innodb buffer pool is a page that s modified in the memory but isn t written back to the disk a free page in innodb buffer pool is a page that doesn t contain any data and is unused innodb fsync calls cloudsql googleapis com database mysql innodb_data_fsyncs the number of innodb

cloudsql googleapis com database mysql innodb_pages_read cloudsql googleapis com database mysql innodb_pages_written the number of innodb pages read and written mysql table open cache cloudsql googleapis com database mysql open_tables cloudsql googleapis com database mysql opened_table_count open_tables is the number of tables currently open opened_table_count is the number of tables that the database has opened since the last sample if the value of opened_table_count is consistently high we recommend that you increase the value of table_open_cache mysql table definition cache cloudsql googleapis com database mysql open_table_definitions cloudsql googleapis com database mysql opened_table_definitions_count open_table_definitions is the number of table definitions that are currently open opened_table_definitions_count is the number of times the database has opened a table definition since the last sample if the value of opened_table_definitions_count is consistently high we recommend that you increase the value of table_definition_cache innodb data dictionary memory usage cloudsql googleapis com database mysql innodb dictionary_memory memory usage for the innodb data dictionary cache innodb has its own cache for storing information about database objects such as tables columns indexes and foreign keys table_definition_cache sets a soft limit on the number of tables in this cache however tables with foreign key relationships are kept in cache until the database shuts down or restarts this cache can consume a significant amount of memory if your instance has many tables with foreign key relationships disk storage by type cloudsql googleapis com database disk bytes_used_by_data_type the breakdown of instance disk usage by data types such as data binlog and tmp_data this metric helps you understand your storage costs for more information about storage usage charges see storage and networking pricing point in time recovery pitr uses binary logs cloud sql generates new logs regularly and these logs use storage space cloud sql automatically deletes the binary logs and their associated automatic backups this generally happens after the retention value set for transactionlogretentiondays is met transactionlogretentiondays is the number of days for which cloud sql retains the transaction logs its value ranges from 1 to 7 to avoid unexpected storage issues while using pitr we recommend that you enable automatic storage increases disk read write ops cloudsql googleapis com database disk read_ops_count cloudsql googleapis com database disk write_ops_count read_ops_count indicates the delta count of disk read i o operations you can use this metric to understand whether your instance is correctly sized for your environment if required you can switch to a larger machine type to serve more requests from cache and reduce latency write_ops_count indicates the delta count of disk write i o operations cloud sql instances barring replicas
