eG Monitoring
 

Measures reported by MariaSqlNetTest

This test monitors the availability and responsiveness of the Maria Database server by emulating a client connecting and executing queries on the Maria Database server.

Outputs of the test : One set of results for the Maria database server being monitored.

Measurement Description Measurement Unit Interpretation
Availability Indicates whether the database instance is responding to requests. Percent The availability is 100% when the instance is responding to a request and 0% when it is not. Availability problems may be caused by a misconfiguration/malfunctioning of the database instance, or because the instance is using an invalid user account. 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 DB connection availability and Query processor availability 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?
Conn_time Indicates the time taken by the database connection. Secs A high value could indicate a connection bottleneck. Whenever the Total response time of the measure soars, you may want to check the value of this measure to determine whether a connection latency is causing the poor responsiveness of the server.
MariaConAvailable Indicates whether the database connection is available or not. Percent 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 Oracle server availability measure reports the value 0, then, you can check the value of this measure to determine whether/not it is due to the unavailability of a connection to the server.
Statement_availability Indicates whether the database query is executed successfully or not. Percent If this measure reports the value 100, it indicates that the query executed successfully.  The value 0 on the other hand indicates that the query failed. In the event that the Maria server 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 a server unavailability. 
Statement_exec_time Indicates the time taken for query execution. Secs A high value could indicate that one/more queries to the database are taking too long to execute. Inefficient/badly designed queries to the database often take too long to execute. If the value of this measure is higher than that of the Connection time measure, you can be rest assured that long running queries are causing the respond slowly to requests.
No_of_records Indicates the number of records fetched from the database. Number The value 0 indicates that no records are fetched from the database.
Response_time Indicates the time taken by the database to respond to a user query. This is the sum total of the connection time and query execution time. Secs Although included as part of the MariaSqlNetTest test, this measure maps to the Oracle Service layer.
