2. Make the following common configurations:
3. Create message(s) for transmission using the Reporting view.
HTTP Messenger does not require any specific format to be used;
instead, the format depends on the receiving server application.
Table 38 Configurations for HTTP Messenger
Parameter Use Note
Primary
interface Primary network interface for
contacting the server. Backup(s) may be specified in
parameter set hosts.
Queue
location File system location where
outgoing messages will be
queued for transmission.
The available options are:
- RAM disk
- External CFS
(requires CF card)
(non-volatile)
- Internal logfile system
(non-volatile)
Specify the same location for
all HTTP clients in the system.
Queue size Number of items, for example,
reports, stored in the queue. If
this limit is exceeded due to,
for example, network
congestion, the oldest queue
item will be deleted for each
new one.
QML can buffer data within
limitations of the selected
storage location and certain
file system constraints.
Absolute maximum of 500
items is in effect. Buffering
data in RAM disk will consume
dynamic memory from the rest
of the application. Likewise,
the other storage alternatives
will consume logging space.
Max
response Maximum size of the expected
HTTP response (bytes). Depending on server
configuration, HTTP
responses can sometimes be
quite verbose and even
contain formatting.
Retries Number of retries in case of
failure.
Options - Debug information to COM0
- In case a backup interface is
used, the first attempt is
always made to primary target. Backups for HTTP are
configured using parameter
set hosts.
