Description |
Measurement
Unit |
Interpretation |
| Availability |
Indicates the availability of the server. |
Percentage |
The availability is 100% when the server is responding 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. |
| Response_time |
Indicates the time taken by the database to respond to a user query |
Seconds |
A sudden increase in response time is indicative of a bottleneck at the database server. |
| MssqlConAvailable |
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/not it is due to the unavailability of a connection to the server. |
| MssqlConResTime |
Indicates the time taken by the database connection. |
Seconds |
A high value could indicate a connection bottleneck. Whenever the SQL 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. |
| MssqlQryAvailable |
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 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. |
| MssqlQryResTime |
Indicates the time taken for query execution. |
Seconds |
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 run for long periods. If the value of this measure is higher than that of the MssqlConAvailable measure, you can be rest assured that long running queries are the ones causing the responsiveness of the server to suffer. |
| MssqlNoOfRecords |
Indicates the number of records that were fetched from the database. |
Number |
The value 0 indicates that no records are fetched from the database. |
