SAP HANA Replication Secondary DB Statistics Monitoring

SAP HANA Replication Secondary DB Statistics Monitoring

This monitor targets SAP HANA secondary replication service entries
and lets you scope monitoring by host/service.
It provides alarm/metric configuration hooks per surveillance row.

This monitor is currently work in progress

What Can Be Monitored

You can configure monitoring scope by:

Primary host filter
Service (port) filter
Per-row activation, alarm enablement, and metric enablement

Current implementation note: this monitor runner currently has no threshold evaluation logic, so no concrete secondary-statistics alarm rule is executed yet.

Monitored Data

The monitor input job requests replication status data (from HANA replication service views), including:

Host and service identity
Primary/secondary replication context
Replication status/mode metadata
Related replication statistics fields available in the shared replication result set

Configuration Hints

One surveillance row defines one host/service selection scope.
Wildcards are supported in Host and Service (for example `*`).
Auto clear controls whether generated alarms are clearable.
Alarm and Metrics flags enable corresponding output paths for that row.

Configuration

Monitoring Parameters

Parameter	Type	Required	Default	Description
(none)	-	-	-	This monitor has no global parameters; configuration is done in the surveillance table.

Surveillance Table

Field	Required	Default	Description
Active	Yes	`true`	Enables/disables this surveillance row.
Host	Yes	`*`	Primary host selector (supports wildcard matching).
Service	Yes	`*`	Service/port selector (supports wildcard matching).
Auto clear	Yes	`true`	Alarms generated by this row are clearable when enabled.
Severity	Yes	`Critical`	Default alarm severity for this row (`5 ⇒ Critical`).
Alarm tag	No	(empty)	Optional custom alarm tag/prefix.
Alarm	No	`true`	Enables/disables alarm generation for this row.
Metrics	No	`false`	Enables/disables metric generation for this row.

Alarm Conditions

In the current implementation, no explicit threshold/condition checks are implemented in this monitor runner. As a result, there are no active built-in alarm trigger conditions yet.

Generated Metrics

In the current implementation, no metrics are emitted by this monitor runner.

Generated Alarms

In the current implementation, no alarms are emitted by this monitor runner.

Example

Active	Host	Service	Auto clear	Severity	Alarm tag	Alarm	Metrics
true	`*`	`*`	true	Critical	`HANA,REPLICATION,SECONDARY`	true	false
true	`hana-prd-*`	`3*`	true	Major	`HANA,SECONDARY,PRD`	true	true
