The NetMRI and Event Collector (EC) interact over the network in several
different modes. Different ports are used for these different modes, as
follows:
NetMRI to EC
- Port 8089 is used for the Event Indexer API.
This is used to retrieve and save search criteria, as well as perform the
auto-login when the user hits the Event Browser link. It is also used
internally for performing searches related to the Event Summary screen, and
other places.
- Port 80 is used for the EAM API. This includes updating
how the symptoms map to search criteria, the administrator password, and
pushing device, interface, and group data to the EC for event enhancement.
- Port 22 is used to create a tunnel from the
NetMRI to the EC GUI. This proxies NetMRI port 9100 to EC port 8000.
EC to NetMRI
- Port 80 or 443 is used to send symptom reports
to the NetMRI from the EC, as well as to register the EC with the NetMRI,
depending on whether HTTPS is enabled on the NetMRI or not. The setting in the
"Register" page is used for the initial registration request. After
that, if https is enabled on the NetMRI, it will be used, and the EC will be
reconfigured to show this.
Browser To NetMRI
- Port 9100 must be open from the browser to the
NetMRI for the Event Browser to work. This is forwarded by the ssh tunnel to
port 8000 on the EC.
- Of course Port 80 or 443 must be open on NetMRI
(this is not a new requirement).
Browser to EC
- No ports are needed from the browser to the EC.
This is why we use the ssh tunnel to proxy the EC on the NetMRI.
- Port 22 is required for any admin user that
needs ssh access to the EC.
