information, and writes the status information to the system log file. The status
information includes all parameter values and all alarm states.
The time interval for any network element can be changed using a
SET RECORD
command. EMS also writes a status report into the log file whenever any alarm
changes in state (for example, from
Green to Red). An entry remains in this
file until the age of the entry in days is the “trim time” value plus one. “Trim time”
is a user-set value (for more information, refer to Topic
3.5 on page 32).
The log file is the source of the information displayed in response to
GET
PLAYBACK
commands. By default EMS writes to the log file for each network
element periodically per a system default period or optionally per the period
defined by a user using a
SET RECORD command.
NOTE: The SET RECORD time interval can be set to zero, causing no records to
be kept. If no records are kept, then the POST MESSAGE and GET PLAY-
BACK functions will yield no information because there will be no information
available to be retrieved.
To determine the current intervals for creating records
1. Enter a command in the following format
DEMS Site_Name GET RECORD
(or)
DEMS Node_Number GET RECORD
where Site_Name is the site name of the network element and
Node_Number is the Host Node or Remote Node value (as displayed in
the Maintenance interface View Catalog window). Use
Site_Name = ALL
to query all network elements at the same time.
2. Look for a response like this
1130 23-Mar-01 DEMS(37 Host.12)GracesFood GET RECORD \
10:00
END
where 10:00 indicates a recording time interval of ten minutes and zero sec-
onds.
Examples
