B. ITSLM Communication

This section uses the example system configuration shown below to explain the port numbers used in ITSLM 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 ITSLM - Manager.
ITSLM - UR is deployed to monitor the Web system services.
The PFM - Manager that is linked to ITSLM - Manager is deployed.
To monitor a monitored server, PFM - Agent is deployed on the monitored server.

Communication between ITSLM - Manager and the browser

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

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

Communication between ITSLM - Manager and ITSLM - UR

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

Port number of ITSLM - Manager	Communication protocol	Port number of ITSLM - 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 ITSLM - Manager and PFM - Manager

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

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

Communication between ITSLM - Manager and PFM - Base

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

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

In addition to these communications, communications using ports 20901/tcp to 20904/tcp are available on the local host on which ITSLM - Manager is run. Communication using port 20910/tcp is also available on the local host on which ITSLM - UR is run.
