Method 1: WLM query monitoring rules. If you see very large discrepancies please let us know. STL_QUERYTEXT - This table contains the full query, but unfortunately one single query split into multiple rows, so we need to concat all these rows into a single row. select query, trim (querytxt) as sqlquery from stl_query where label not in ( ' metrics ' , ' health ' ) order by query desc limit 40 ; To add to Alex answer, I want to comment that stl_query table has the inconvenience that if the query was in a queue before the runtime then the queue time will be included in the run time and therefore the runtime won't be a very good indicator of performance for the query. This difference should account for small differences in their data. Whereas SVL_S3QUERY_SUMMARY is populated after the query completes. Amazon Redshift is designed to utilize all available resources while performing queries. ~20% were very short queries (< 1min), metrics, health and stats (internals of Redshift). In this post, we're going to get the monitoring data about AWS Redshift and make it available to Elastic cloud; some of the steps in this … AWS RedShift is a managed Data warehouse solution that handles petabyte scale data. Use the WLM query monitoring rules when you want to manage workload according to metrics-based performance boundaries. The Amazon Redshift CloudWatch metrics are data points for use with Amazon … An increase in CPU utilization can depend on factors such as cluster workload, skewed … For example, service_class 6 might list Queue1 in the WLM configuration, and service_class 7 might list Queue2. These metrics, when collected and aggregated, give a clear picture of tenant consumption inside a pooled Amazon Redshift cluster. Amazon Redshift also counts the table segments that are used by each table. This is caused by the change in number of slices. Therefore, it's expected to see spikes in CPU usage in your Amazon Redshift cluster. Since a few months ago our usages have slightly changed as more analysts came and a new set of exploratory tools is being used. In your output, the service_class entries 6-13 include the user-defined queues. In Amazon Redshift, you can change the queue priority by using WLM query monitoring rules (QMRs) or built-in functions. Run the a query on STL_QUERY to identify the most recent queries you have ran and copy the query_ID for the query you want more details. You are going to use in the svl_query_report next. STL_QUERY_METRICS and STL_WLM_QUERY are two of several tables that provide useful metrics such as query execution time and CPU time. We’ve decided to deploy Tableau to all project managers and analysts to improve agility in data-driven decision making. This data is sampled at 1 second intervals. This blog post helps you to efficiently manage and administrate your AWS RedShift cluster. To obtain more information about the service_class to queue mapping, run the following query: Elasticsearch can be used to gather logs and metrics from different cloud services for monitoring with elastic stack. The Amazon Redshift system view SVL_QUERY_METRICS_SUMMARY shows the maximum values of metrics for completed queries, and STL_QUERY_METRICS and STV_QUERY_METRICS carry the information at 1-second intervals for the completed and running queries respectively. STL_QUERY - Great table, but if your query is huge in size, then it’ll truncate your query, so you’ll not get the complete query. SVL_QUERY_METRICS_SUMMARY is ultimately based on the data in STL_QUERY_METRICS. You can use the new Amazon Redshift query monitoring rules feature to set metrics-based performance boundaries for workload management (WLM) queues, and specify what action to take when a query goes beyond those boundaries. For example, for a queue that’s dedicated to short running queries, you might create a rule that aborts queries that run for more than 60 seconds.
