Measures reported by HanaDbUptimeTest
Frequent database restarts or intermittent breaks in database availability are signs of poor database server health. Administrators hence need to track the uptime of each database in SAP HANA, so that they can quickly compare that with service level targets to identify trouble-prone or unstable databases. To achieve this, administrators can use the HanaDbUptimeTest test.
This test auto-discovers the databases on SAP HANA and reports the uptime of each database, so that those databases that went down frequently can be identified.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| upTimeInMins |
Indicates the total time for which this database was up since its last reboot. |
|
This measure displays the number of years, months, days, hours, minutes and seconds since the last reboot. A low value for this measure may be either due to planned maintenace of the database server or a severe problem with the availability of the database server. Sometimes, administrators may also wish to be alerted if a server has been running without a reboot for a very long period. Setting a threshold for this metric allows administrators to determine such conditions. |
| Rebooted |
Indicates whether/not the HANA server was restarted during the last measurement period. |
|
If the server was restarted, this measure will report the value Yes. If it was not restarted, then this measure will report the value No. The numeric values that correspond to these measure values are as follows:
| Measure Value |
Numeric Value |
| Yes |
1 |
| No |
0 |
Note:
By default, this measure reports the Measure Values in the table above to indicate whether/not the server rebooted. However, in the graph of this measure, the same is represented using the numeric equivalents only. |
