Configuring ITO
Flexible-management Configuration
ITO management server is able to calculate the local time of the
managed node which sent the message and decide whether or not it is
appropriate to act.
Service Hours are usually defined in terms of the local time on the
managed node. For example, a service provider uses the Service Hours
template to tell the ITO management server that managed nodes in
various time zones must be supported between 08:00 and 16:00 local
time. Templates for Scheduled Outages define time in terms of the local
time on the server providing the service that is scheduled to be
unavailable. For example, the administrator of an ITO management
server in the UK knows that a SAP server situated in Eastern United
States will be unavailable for maintenance reasons between 22:00 and
02:00 US EST.
The templates for scheduled outages and service hours on the ITO
management server can contain a string that defines a fixed local time
zone (e.g. EST for US Eastern Standard Time). The ITO management
server uses the value of the time zone string and the time (in UTC) to
calculate the fixed local time on the given management server for which
an outage has been scheduled. The following example illustrates the
syntax for the time zone string:
TIMEZONETYPE FIX TIMEZONEVALUE EST
By default, ITO evaluates time conditions for both service hours and
scheduled outages by comparing the time frame defined for each
condition to the time the message is received on the ITO management
server. However, this behavior can be modified by setting a parameter in
the opcsvinfo file in the following manner:
• to force the ITO management server to use the message creation time
on the local managed node to evaluate scheduled outage hours rather
than the message arrival time on the ITO management server, enter
the following string in the opcsvinfo file:
OPC_OUTAGE_USE_CREATE_TIME TRUE
• to force the ITO management server to use the message creation time
on the local managed node to evaluate defined service hours rather
than the message arrival time on the ITO management server, enter
the following string in the opcsvinfo file:
OPC_SERVHRS_USE_AGENT_TZ TRUE
