Install VmStat in Linuxīy default vmstat command is not available under Linux systems you need to install a package called sysstat (a powerful monitoring tool) that includes a vmstat program. Linux VmStat command is used to display statistics of virtual memory, kernel threads, disks, system processes, I/O blocks, interrupts, CPU activity, and much more. # topįor more examples of Top command read: 12 TOP Command Examples in Linux 2. The top command is much useful for system administrators to monitor and take corrective action when required. It also shows high memory and cpu utilization of running processes.
It displays CPU usage, Memory usage, Swap Memory, Cache Size, Buffer Size, Process PID, User, Commands, and much more. The top command is used to display all the running and active real-time processes in an ordered list and updates it regularly.

I_looker: i_looker is Looker's legacy set of Explores for internal analytic data. Read replica option: For customer-hosted instances only, this method increases System Activity performance and provides longer System Activity data retention. See the System Activity Explores page for a list of Explores and their cache rules.Įlite System Activity: An optional analytical store that increases System Activity performance and storage limits. System Activity Explores: Using System Activity Explores, you can create your own Looks and dashboards to monitor and analyze your Looker instance. Data in the System Activity dashboards is updated and cached every 12 hours. You can download, schedule, set alerts on, and drill into metrics and elements just like on any other dashboard. System Activity dashboards: Looker-created dashboards showing usage and performance information about the Looker instance. System Activity includes the following elements: Non-admin users can be granted access to System Activity and i_looker if they are given the see_system_activity permission. Looker admins have access to both i_looker and System Activity by default. Take action: Modify who has view access to the System Activity and i_looker models. For customers using i_looker: The i_looker model contains accessible SQL text in addition to filter text. The text in filters run by users is accessible in System Activity and can be viewed by any user who has permission to view the System Activity model. This data can be useful for supplementing monitoring and auditing activities, but is not intended to replace your current compliance strategy. System Activity is designed for collecting high-volume data, and aggregating it can be used to supplement your business logs. Both the granularity and retention of System Activity data are subject to system constraints. System Activity Explores and dashboards built upon this model show information about your Looker instance, including all Looks and dashboards saved on your instance, user information, historical query information, and instance performance statistics. System Activity is an internal LookML model that connects to Looker's underlying application database.
