Description |
Measurement Unit |
Interpretation |
| Availability |
Indicates the availability of the database server. |
Percent |
A value of 100 indicates that the database server is currently available and a value 0 indicates that the database server is currently unavailable.
A database server may be unavailable either when the server has not been started or due to misconfiguration/malfunctioning of the database server.
|
| MssqlConResTime |
Indicates the time taken by this server to connect to the database server. |
Secs |
A low value is desired for this measure. A high value could indicate a connection bottleneck. Whenever the Total response time 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. |
| MssqlNoOfRecords |
Indicates the number of records that were fetched from the database. |
Number |
If the value of this measure is 0, then it indicates that no records have been fetched from the database. |
| MssqlQryAvailable |
Indicates whether the database query is executed successfully or not. |
Percent |
A value of 100 for this measure indicates that the query was executed successfully. The value 0 on the other hand indicates that the query failed. In the event that the SQL 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 server unavailability. |
| MssqlQryResTime |
Indicates the time taken by the database server to execute a query. |
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 run for long periods. If the value of this measure is higher than that of the Database connection availability measure, you can be rest assured that long running queries are the ones causing the responsiveness of the server to suffer. |
| Response_time |
Indicates the time taken by the database server to respond to a user query. |
Secs |
This measure is the sum total of the Connection time to database server and Query execution time measures.
A low value is desired for this measure. A gradual/sudden increase in response time is indicative of a bottleneck at the database server.
|
| MssqlConAvailable |
Indicates whether the database connection is currently available or not. |
Percent |
A value of 100 for this measure 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 SQL 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. |
