The omegamon.rls
rule set file has parameters that you
can edit, according to your environment, to tune performance or to
set your own customized values. Using these parameters, you can write
and customize Tivoli Enterprise Console rules.
During installation, you can choose the location of the rule base.
Otherwise, you can use the wrb -lscurrb -path to find the current
rule base.
Here are some
reasons why you might
want to change the behavior of the rule:
- For the omegamon.rls
file, omegamon_admin is the name of
the rule set but you can name your rule set after your administrator's
name or some other value.
- Similarly, the sit_ack_expired_def_action rule
set name
is set to REJECT by default. This setting means that whenever a situation
event acknowledgement expires in the Tivoli Enterprise Portal and
the event becomes OPEN in the portal, the Tivoli Enterprise Console event
server rejects this action and re-acknowledges the event in the portal.
You have the option of accepting the change that was initiated by
the portal and changing the status in the Tivoli Enterprise Console instead.
The following user-configurable parameters
are available:
- omegamon_admin
- Use this identifier when a rule defined in this rule set closes
an event. This identifier is used to differentiate close operations
that were originated automatically rather than initiated by the console
operator.
- omsync_timeout
- This
attribute sets the period in seconds that you must wait
to distinguish between the synchronization of single or multiple events.
The default timeout is 3 seconds.
- omsync_maxentries
- This attribute sets the maximum number of events allowed per batch.
Default batch size is 100 events.
Warning: Setting this value less than 20 events might cause contentions
within the Tivoli Enterprise Console task
process, causing poor performance of events that are synchronized
back to the Tivoli Enterprise Monitoring Server.
- sit_resurface_def_action
- This attribute
determines the default action of the rules in case
a situation update event arrives from Tivoli Enterprise Monitoring Server to
resurface or reopen an event that has already been acknowledged. The
two possible values are ACCEPT and REJECT. The default is ACCEPT.
- sit_ack_expired_def_action
- This attribute
determines the default action of the rules in case
a situation update event arrives from the Tivoli Enterprise Monitoring Server to
reopen an event that has already been acknowledged. This happens when
a situation's acknowledgement in the monitoring server expires
and the situation event is reopened. The two possible values are ACCEPT
and REJECT. The default is REJECT.
- sf_check_timer
- This attribute specifies the interval at which the state of the
situation update forwarder is checked. It reads events from the cache
files and send them to the Tivoli Enterprise Monitoring Server using Web Services. The
default is 10 minutes.
After
modifying any configuration parameters and saving
omegamon.rls, you must recompile and reload the rule base and recycle
the event server. To recompile the rule base, enter the following
command, where
Rulebase_Name is the name of the actively
loaded rule base containing the omegamon.rls rule set:
wrb -comprules Rulebase_Name
To
reload the rule base, issue the following command:
wrb -loadrb Rulebase_Name
To
stop the Event server, issue the following command:
wstopesvr
To
restart the Event server issue the following command:
wstartesvr
