eG Monitoring
 

Measures reported by SFSQLNetTest

Client data is stored in a database within one of the virtual warehouses hosted on the Snowflake data cloud service. Customers need to have uninterrupted access to their data. Any network issue can at disrupt business customer's critical services and need to be handled and fixed at highest priority. The administrators would like to know in real time if there is any downgrade in the quality of service so that they can take corrective actions in advance.

eG Enterprise uses a JDBC connection to connect to the target database and warehouse in the Snowflake data cloud service. This test monitors the availability and responsiveness of the service and collects statistics related to the traffic in and out of the service..

Outputs of the test:One set of results for each database present in the warehouse being monitored.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Availability Indicates whether the network connection is available or not. Percentage The availability is 100% when the server does respond to a request and 0% when it is not. Availability problems may be caused by a misconfiguration / malfunctioning of the database server, or if the server has not been started.

Besides the above, this measure will report that the server is unavailable even if a connection to the database instance is unavailable, or if a query to the database fails. In this case, you can check the values of the SnowflakeConAvailable and SnowflakeQryAvailable measures to know what is exactly causing the database instance to not respond to requests - is it owing to a connection unavailability? or is it due to a query failure?

The detailed diagnosis of this measure shows the exact error message received while connecting to database in Details of connection availability field.
ResponseTime Indicates the time taken by the database to respond to a user query. This includes both connection time and query execution time. Seconds A sudden increase in response time is indicative of a bottleneck with the database server.
ConnAvailability Indicates whether the database connection is available or not. Percentage If this measure reports the value 100 , it indicates that the database connection is available. The value 0 on the other hand indicates that the database connection is unavailable. A connection to the database may be unavailable if the database is down or if the database is listening on a port other than the one configured for it in the eG manager or owing to a poor network link. If the Availability measure reports the value 0, then, you can check the value of this measure to determine whether or not it is due to the unavailability of a connection to the server.
ConnResponseTime Indicates the time taken to connect to the database server. Seconds A dramatic increase in this value may be because the service has reached its connection handling capacity.
QueryAvailability Indicates whether the database query is executed successfully or not. Percentage If this measure reports the value 100, it indicates that the query was executed successfully. The value 0 on the other hand indicates that the query failed. If the Availability measure reports the value 0, check the value of this measure to figure out whether the failed query is the reason why that measure reported server unavailability.
QueryResponseTime Indicates the time taken to execute a database query during the last measurement period. Seconds A jump in value as compared to the last measurement could indicate a bottleneck in processing.
RecordCount Indicates the number of records fetched from the database during the last measurement period. Number The value 0 indicates that no records are fetched from the database.
