Guided Procedures for HANA AlertsTrigger for Guided Procedures from Alert Inbox

Guided Procedure

Perform alert resolution in a guided and

reproducible way:

• Assign Guided Procedures to alert groups direct

in Alert Inbox

• Execution of Guided Procedure is possible out

of Alert Inbox

• Execute the Guided Procedure in order to

analyze the root cause of a problem

• SAP delivers Guided Procedures for HANA

Alerts with Solution Manager (currently 14)

these can be copied and adjusted by

customers

Alert Inbox


Availability of Alert Metrics

• All HANA alert ids >= 68 are available only with HANA embedded statistics server

• HANA embedded statistics server can be activated as of HANA Rev 74

• As of HANA Rev 96 embedded statistics server is enabled by default

• Solution manager based monitoring of HANA with embedded statistics server required Solman 7.1

>= SP10

• Via content update all existing metrics are already available for Solman 7.1 SP12 and downport

of new metrics will be continued – downport to SP10+11 currently in process


Mini Checks

• Mini Checks are a collection of SQL statements for manual execution of HANA health checks

Available via SAP note 1999993

• They are very flexible and are quickly adapted to latest findings and partially provide quick an simple manual

check capabilities are also frequently used by SAP support.

• They are also taken as a basis for content to be added as regular alerts (typically initially as Solman based

alerts and in a next HANA SP also as a HANA internal alert) or as EarlyWatch Alert checks.

Example excerpt of a mini check output:


Further Documentation

• Online documentation within each alert and metric

• Where available, guided procedures are directly linked to the alerts

• Offline documentation can be created as html page or XLS list per template

This is very helpful for offline documentation of customized templates

• List of all metrics with links to detailed SAP notes available via SAP note 2053330

• HANA Troubleshooting and Performance Analysis Guide

• How to develop own HANA custom metrics within Solution Manager:

DB instance level introduced as of SolMan 7.1 SP14

DB Level

DB Instance Level

Host Level

HANA template maintenance

• DB Level

• SAP HANA DB (NEW)

• 1:1 relation of HANA alerts to Solman alerts

• Contains all HANA metrics (instance level as metric groupings)

• SAP HANA DB (OLD)

• no 1:1 relation of HANA alerts to Solman alerts

• Contains all HANA metrics (instance level as metric groupings)

• kept for compatibility only

• SAP HANA DB (instance level separated)

• Contains all HANA metrics except instance level metrics

• DB Instance Level

• SAP HANA DB Instance

• Contains instance specific metrics only

• Instance level separation better UI separation (optional)

• All metrics are still available via non-instance specific

templates (no action required after Solman upgrade )

• Limitation: instance level metrics cannot be used for multi database container DBs

For replication scenarios

(see next slide)


Replication Monitoring as of SolMan 7.1 SP14 + HANA SPS10

Replication scenario

/ virtual DB

Primary clusterSecondary cluster

• Automatic landscape recognition requires

HANA SPS10

• Requires SAP Hostagent 7.21 pl >= tbd

• Replication status metrics on

replication scenario level

• Active DB metrics collected on

primary DB cluster only

• Host level monitoring on all hosts

(primary + secondary)

• No DB metrics collected on secondary

DB (no SQL connect possible yet).

Instance and DB level inherit status

from below only

• DB switch over automatically detected

and monitoring re-configuration triggered

• Further „secondary“ clusters also supported

• Limitation: not available for multi database

container DBs


System Monitoring for SLT

Availability- Connectivity status

- Replication queue sizes

Exceptions- Jobs status

- Trigger status

Prerequisites:

• DMIS 2010 >= SP6 or 2011 >= SP1, see note 2081759

• SolMan 7.1 >= SP6 with latest monitoring content update

• Integrated into ABAP system level metrics

• Template: SAP SLT ABAP Addon

Performance- Latency (per schema, table)

- Replication queue sizes
