Introduction

System monitoring is a daily routine activity and this document provides a systematic step by step procedure for Server Monitoring. It gives an overview of technical aspects and concepts for proactive system monitoring.

Scope

The document covers all the transactions which are being used for checking system health in order to arrest the problems before they actually occurs. After reading this document reader will have a fair idea about the process and the method followed for system monitoring. The main areas being covered in the document are as under :-

Checking Application Servers. Monitoring Application Users. Monitoring System wide Work Processes. Monitoring application User Monitoring Work Processes for Individual Instances. Monitoring Update Processes. Monitoring Lock Entries. Monitoring System Log. CPU Utilization Buffer Statistics Available Space in Database. Checking Missing indexes. Monitoring Batch Jobs Spool Request Monitoring. Number of Print Requests ABAP Dump Analysis. Database Performance Monitor. Database Check.

The document encompasses all the activities which are included in our business process and liable to change as and when new business process is introduced or change in the existing process.

Login to SAP

1. Select SAP Logon Icon from the desktop.

2. System list pops up.

3. Select the system name from the list and double click.

4. Enter User ID and Password here.

5. You are logged in.

After logging in system displays screen as below.

To run any transaction we need to write transaction code in Command Field.

Server Monitoring

Checking Application Servers (SM51)

This transaction is used to check all the active application server.

Monitoring Work Processes for Individual Instances (SM50).Displays all running, waiting, stopped and PRIV processes related to a particular instance. Under this step we check all the process, the process status should always be waiting or running. If any process is having status other then waiting or running we need to check that particular process and report accordingly.

Monitoring System wide Work Processes (SM66)We can quickly investigate the potential cause of a system performance problem by checking the work process load and can use the global work process overview to:

Monitor the work process load on all active instances across the system

Identify locks in the database (lock waits).

Using the Global Work Process Overview screen, we can see at a glance:

The status of each application server

The reason why it is not running

Whether it has been restarted

The CPU and request run time

The user who has logged on and the client that they logged on to

The report that is running

We record only those processes which are showing problems and not having running status.

Monitor Application User (AL08) This transaction displays all the users of active instances.

We record total number of users in our log.

Monitoring Update Processes (SM13)Execute Transaction SM13 and put * in the field USER.This transaction is used to check the following activities:

1. Is the update active, if not , was it deactivated by system or by user.2. Have any update been cancelled.3. Is there a long queue of pending updates older than 10 minutes.

Monitoring Lock Entries (SM12)Execute Transaction SM12 and put * in the field User NameWe can use lock statistics to monitor the locks that are set in the system. We record only those lock entries which are having date time stamp of previous day.

Monitoring System Log (SM21)We can use the log to pinpoint and correct errors occurring in the system and its environment. We check log for the previous day, and time is entered as shown in the screen below. Then select Radio Button Problems and Warnings and press Reread System Log.

We write total number of records, as shown in the screen below, in our log and analyze the problems which are not displayed in ST22.

CPU Utilization (ST06)

In CPU Utilization we record User, System, Idle and Wait percentage utilization from the above screen.

Available Space in Database (DB02)

Space statistics are taken from the below screen and we record Total Size in GB and Total free space in percentage.

Checking Missing indexes (DB02)At the same screen missing indexes statistics can also be checked by pressing Missing Indexes button, below screen pops up. Record primary and secondary missing indexes.

ABAP Dump Analysis (ST22)Here we check for previous day’s dumps.

Open the details log of each and every dump by double clicking it and try to find out any suitable notes, analyze them and propose suitable solution as per SAP standards.

Spool Request Monitoring (SP01)In spool request monitoring execute sp01 and put * in the field Created By and press execute button.

Here we record only those requests which are terminated with problems.

Number of Print Requests (SPAD)Execute SPAD and press Admin button.

Now select Print Request Overview button.

Record Total Print Requests from below screen.

Monitoring Batch Jobs (SM37)Execute SM37 and put * in the field User Name record number of Scheduled, Cancelled, Released and Finished requests.

Batch Input Session Lock (SM35)Execute SM35 and press Locked Button. Record number of requests displayed.

Database Performance Monitor (ST04)Record Quality %, if its is >=95 write 0 else write actual percentage displayed.

Database Check (DB16)Record all the Errors and Warnings, analyze the cause and propose solution.

Checking CORE file (ST11)Execute ST11 and search for core file. Record the actual file size in the log.

We have to check each and every instance shown in SM51 for the for core file.

Excel Sheet Format.

Below is the format for recording all the entries we have discussed until now.
