B. SLM Communication

This section uses the example system configuration shown below to explain the port numbers used in SLM communication and the direction in which data passes through a firewall (the direction in which a connection is established).

Figure B‒1: Example system configuration

The person who monitors services uses a browser to connect to SLM - Manager.
SLM - UR is deployed to monitor the Web system services.
The PFM - Manager that is linked to SLM - Manager is deployed.
To monitor a monitored server, PFM - Agent is deployed on the monitored server.

Communication between SLM - Manager and the browser

Communication between SLM - Manager and the browser is as follows:

Port number of the browser

Pass-through direction

Communication protocol

Port number of SLM - Manager (HTTP server)

(ANY)/tcp

HTTP

20900/tcp (httpsd)

Port number of the browser	Pass-through direction	Communication protocol	Port number of SLM - Manager (HTTP server)
(ANY)/tcp		HTTP	20900/tcp (httpsd)

Communication between SLM - Manager and SLM - UR

Communication between SLM - Manager and SLM - UR is as follows:

Port number of SLM - Manager	Communication protocol	Port number of SLM - UR
(ANY)/tcp	RMI	20910/tcp (`jslmuRMI`)
(ANY)/tcp	RMI	(ANY)/tcp
20904/tcp (`jslmmRMI`)	RMI	(ANY)/tcp
(ANY)/tcp	RMI	(ANY)/tcp

Communication between SLM - Manager and PFM - Manager

Communication between SLM - Manager and PFM - Manager is as follows:

Port number of SLM - Manager	Pass-through direction	Communication protocol	Port number of PFM - Manager
(ANY)/tcp		RMI	22286/tcp
(ANY)/tcp		RMI	(ANY)/tcp

Communication between SLM - Manager and PFM - Base

Communication between SLM - Manager and PFM - Base is as follows:

Port number of SLM - Manager	Pass-through direction	Communication protocol	Port number of PFM - Base
20905/tcp (`jslmmadaptor`)		TCP	(ANY)/tcp

In addition to these communications, the following communications are also available:

Communications using ports in the range from 20901/tcp to 20904/tcp on the local host on which SLM - Manager is running
Communications using port 20910/tcp on the local host on which SLM - UR is running
Collection of HTTP packets by SLM - UR

Set up the firewall so that SLM - UR can obtain HTTP packets that were copied by the port mirroring function.

To specify a program to allow communication, specify settings on the host where SLM - UR was set up so that communication of the following program is allowed:
- SLM-UR-installation-folder\ur\system\sdp\bin\sdppcap.exe
