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).
-
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
Pass-through direction
Communication protocol
Port number of ITSLM - UR
(ANY)/tcp
RMI
20910/tcp (jslmuRMI)
(ANY)/tcp

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

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.
