GRMG and CCMS

[sap_cohort]

Hi, I do not have any exposer to GRMG and I'm curious if anyone can explain what it is from a high level and what is the difference between GRMG and CCMS?

Thanks for the help...

Hi,

Here is basic definition and relation between CCMS and GRMG:

The GRMG consists of two parts, both of which are required for a functioning GRMG

environment:

1. GRMG infrastructure

The GRMG infrastructure is part of the monitoring architecture of the Computing

Center Management System (CCMS) of an SAP NetWeaver AS ABAP. Its task

is to send a request (the GRMG request) to the GRMG application, to receive

its response (the GRMG response), and to display this response in the CCMS

Alert Monitor.

2.GRMG application

The GRMG application performs the actual availability monitoring. From a

technical point of view, it is a Java Server Page (JSP), a servlet, or a Business

Server Page in an SAP NetWeaver Application Server with a defined interface

that is called by the GRMG infrastructure. The GRMG request and GRMG

response are messages in a special XML format.

You can use a central monitoring system to monitor the availability selected

components of an SAP solution with the GRMG. The GRMG is suitable both for

technical monitoring and for application monitoring. GRMG availability monitoring

uses functions of the CCMS monitoring infrastructure (SAP NetWeaver AS ABAP) to

store the heartbeat information. The communication is performed using HTTP POST.

Note: Heartbeat - A signal is sent by the software at regular intervals to

communicate the availability (running/not running).

GRMG monitoring is performed as follows:

1. An XML message is sent from the GRMG infrastructure to the target system.

2. The GRMG application on the target system performs all of the tests for the

availability monitoring of the component to be monitored or the business process

step. The results of these tests are collected in the GRMG application and

combined as the GRMG response.

3. The GRMG response is sent back to the GRMG infrastructure and is displayed

in the Alert Monitor of the SAP NetWeaver AS ABAP as heartbeat information.

Thanks for the respones. I was hoping for a simpler description of GRMG and how it integrates with CCMS. The quoted documentation is difficult to understand for someone looking at it for the first time.

Thanks for the help.

Hi Ken,

GRMS is Java monitoring which helps in checking Availability and performance of Portal and Java Stack.

CCMS is for ABAP based monitoring where you can monitor most of the activities in SAP system and Alerts can be configured based on your reuiqrement.

GRMG - Refer to below SAP doc for more information.

http://help.sap.com/saphelp_nw04/helpdata/en/34/60cdd0d3fdeb4cb8cbc4eac681f961/content.htm

CCMS - You need to install the CCMS agents and connect to Solution Manager to monitor the system and trigger alerts from Solman.

Refer to below docs on Installing CCMS and more information.
