Snowflake Query Executions Test

Query performance is key to any database or data store. Many factors can affect the performance and throughput of queries like the load on the target database, query complexity, blocked queries, etc. If the query performance is not up to the mark, it will directly and immediately impact the performance of customers application using Snowflake database and in worst case might disrupt business critical services. Administrators need to be fully aware if there is any degradation in query performance so that they can take corrective actions right at the start of it before it goes any worse and impact customer experience.

This test monitors each database for query execution and provides vital statistics related to the number of running, blocked, and queues queries.

Target of the test : Snowflake Database Server

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each database in the Snowflake service account being monitored.

 

Configurable parameters for the test

Parameter	Description
Test period	How often should the test be executed.
Host	The IP address of the Snowflake.
Port	The port number through which the snowflake database server communicates. The default port is 443.
Warehouse Name	In this text box, enter the name of a virtual warehouse that needs to be monitored.
Database Name	In this text box, enter the name of a default database that will connect the snowflake server.
User	Specify the name of the user who has any of the following privileges to the specified.
Password	The password of the specified USER.

Measurements made by the test

Measurement	Description	Measurement Unit	Interpretation
Resuming	Indicates the total number of query executions that are in resuming status during the last measurement period.	Number
Running	Indicates the total number of query executions that are in running status during the last measurement period.	Number
Successful	Indicates the total number of successful query executions in the last measurement period.	Number
Blocked	Indicates the total number of query executions that are in blocked status during the last measurement period.	Number	Too many blocked queries mean the system throughput will decrease, users will have to wait for query results and query queue will grow. Overall, it will affect the system performance badly. If the blocked query number is high, it needs to be investigated.
Queued	Indicates the total number of query executions that are in queued status during the last measurement period.	Number	Large number of queued queries could be a result of problem with query execution, or would indicated too many blocked queries. The cause of the same will need to be investigated.
Failed with the incident	Indicates the number of query executions that have failed with an incident during the last measurement period.	Number	The failure could be because of the limitation of Snowflake, the incident make sure the Snowflake team is working on it. If the incident is causing a major issue, you are advised to check Snowflake’s status page for the status of the incident or if any real-time support is required.
Failed with error	Indicates the number of query executions that have failed with an error during the last measurement period.	Number	If the error code is shown by Snowflake, that mean it is know error due to specific reason, note down the error code and check Snowflake documentation for resolution.
