HANA backups

Purpose

Backups are important for disaster recovery, you have to make sure that DATA and LOG are saved regularly. This monitor will look for the time elapsed between last backup as well as backup size and duration.

Configuration hints

Last backup age For LOG and DATA backup, you can set a threshold to get an alarm if the last backup is too old. Threshold and severity can be set separately

Backup size and duration For each type of backup, you can monitor size and duration and get notified in case threshold is reached.

Expected log mode You can define the expected log mode and get an alarm if the current mode is not as expected

Automatic log backup You can define the expected automatic log backup setting and get an alarm if the current setting is not as expected

Atomic fields

Auto clear	If set, the generated alarms will be automatically cleared from the console if the alarm condition is not fulfilled anymore
Log metric	If enabled, metrics will be sent for LOG backup statistics
Data alarm	If enabled, alarms will be sent for DATA backups
Last data backup threshold	The threshold of the maximum age of the last DATA backup (sec, min, h)
Severity	Last log backup severity
Severity	Log backup duration severity
Severity	Expected log mode severity
Severity	Automatic log backup severity
Data backup duration threshold	Data backup duration threshold (sec, min, h)
Data metric	If enabled, send metrics on DATA backups statistics
Log backup duration threshold	Log backup duration threshold (sec, min, h)
Failures alarm	If enable, send an alarm if a backup is in failed state
Severity	Severity of last data backup
Severity	Severity of data backup duration
Log alarm	If enabled, send alarms for LOG backups
Last log backup threshold	The max age of the last LOG backup
Expected log mode	The expected log mode
Automatic log backup	The automatic log backup setting
Severity	The severity of the alarm sent for backup failures

Surveillance table

Parameter	Description
Active	If checked, the rule is enabled and will be processed
Host	Can be used to restrict the monitoring to a given host (multi instance case). A star (‘*’) will matchany host.
Service	: Defines from which service the backup files will be checked. A star (‘*’) will match any service.
Backup type	The type of backup.
Max size (TB/GB/MB)	The maximum file size. Unit can be specified: TB, GB, MB or KB. If no unit specified, the valuewill be assumed as bytes. If set to 0, the size won’t be monitored.
Severity	Defines the level of severity of the alarm that will be generated if one of the thresholds isreached.
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/metric has to be generated for the given rule.
Metric	Defines if an alarm/metric has to be generated for the given rule.

Generated metrics

metricId	metricUnit	metricTarget	metricDescription
LOG_BACKUP_DURATION	Minutes	SERVICE	The duration of the last LOG backup in minutes.
DATA_BACKUP_DURATION	Minutes	SERVICE	The duration of the last DATA backup in minutes.
TIME_SINCE_LAST_LOG_BACKUP	Minutes	TYPE	The number of elapsed minutes since last LOG backup.
TIME_SINCE_LAST_DATA_BACKUP	Minutes	TYPE	The number of elapsed hours since last DATA backup.
DATA_BACKUP_FILE_SIZE	Bytes	HOST - SERVICE	The size of the DATA backup file.
LOG_BACKUP_FILE_SIZE	Bytes	HOST - SERVICE	The size of the LOG backup file.
