Database disk usage
Purpose
HANA database uses disks for persistence. To run out of disk space is to avoid at all cost to maintain the service running. This monitor will check disk used space of the HANA database at different levels.
Configuration hints
Create a rule in the surveillance table for each type of usage you want to monitor. Use host and service filter to customize the monitoring for a given node or service
Disk usage is computed at differents levels: - Instance level: The combined usage of all services - Service level: The usage of each individual service. Disk utilizations are split into several categories: DATA, LOG, TRACE, DATA_BACKUP and LOG_BACKUP For each category, you can monitor the current disk usage as well as the delta usage over a period of time.
Atomic fields
| Auto clear | If set, the generated alarms will be automatically cleared from the console if the alarm condition is not fulfilled anymore |

Surveillance table
| Parameter | Description |
|---|---|
| Active | If checked, the rule is enabled and will be processed |
| Usage | The type of usage of the disk |
| Host | Can be used to restrict the monitoring to a given host (multi instance case). A star (‘*’) will match any host |
| Service | Defines which service is monitored. A star (‘*’) will match any service, and therefore, it will calculate the combined usage of all services. Otherwise, it is the usage of the specified service that will be calculated |
| Max used space (MB or %) | The alarm threshold for the current disk usage. You can specify percentage or absolute value in Mega Bytes |
| Max used space delta (MB or %) | The alarm threshold on the delta disk usage increase over the period set in the “Delta time” field. Example: Send an alarm if the disk usage increases by 20% in the last 5 min |
| Delta time (min) | The period of time used to make a delta comparison of the disk usage |
| Severity | Defines the level of severity of the alarm that will be generated if one of the thresholds is reached |
| Alarm tag | You can define some text to use as a prefix of the alarm message generated by the current rule |
| Alarm | Defines if an alarm has to be generated for the given rule |
| Metric | Defines if a metric has to be generated for the given rule |
Generated metrics
| metricId | metricUnit | metricTarget | metricDescription |
|---|---|---|---|
| DISK_DATA_USED_SPACE | Percent or Mega Bytes | HOST | Sends disk usage of DATA |
| DISK_LOG_PERCENTAGE_USED | Percent or Mega Bytes | HOST | Sends disk usage ratio of LOG |
| DISK_LOG_USED_SPACE | Percent or Mega Bytes | HOST | Sends disk usage of LOG |
| DISK_TRACE_PERCENTAGE_USED | Percent or Mega Bytes | HOST | Sends disk usage ratio of TRACE |
| DISK_TRACE_USED_SPACE | Percent or Mega Bytes | HOST | Sends disk usage of TRACE |
| DISK_DATA_BACKUP_PERCENTAGE_USED | Percent or Mega Bytes | HOST | Sends disk usage ratio of DATA_BACKUP |
| DISK_DATA_BACKUP_USED_SPACE | Percent or Mega Bytes | HOST | Sends disk usage of DATA_BACKUP |
| DISK_LOG_BACKUP_PERCENTAGE_USED | Percent or Mega Bytes | HOST | Sends disk usage ratio of LOG_BACKUP |
| DISK_LOG_BACKUP_USED_SPACE | Percent or Mega Bytes | HOST | Sends disk usage of LOG_BACKUP |
