Chapter 7 Configuring Call Home
How to Configure Call Home
Periodic Notification
When you subscribe a destination profile to either the Configuration or the Inventory alert group, you
can choose to receive the alert group messages asynchronously or periodically at a specified time. The
sending period can be one of the following:
•
Daily—Specify the time of day to send, using an hour:minute format
hh:mm
, with a 24-hour clock
(for example, 14:30).
•
Weekly—Specify the day of the week and time of day in the format
day hh:mm
, where the day of
the week is spelled out (for example, monday).
•
Monthly—Specify the numeric date, from 1 to 31, and the time of day, in the format
date hh:mm
.
Message Severity Threshold
When you subscribe a destination profile to the Environment or Syslog alert group, you can set a
threshold for the sending of alert group messages based on the message’s level of severity. Any message
with a severity lower than the specified threshold of the destination profile is not sent to the destination.
Table 7-1
lists the keywords used to configure the severity, which range from catastrophic (level 9,
highest level of urgency) to debugging (level 0, lowest level of urgency). If no severity threshold is
configured, the default is debugging (level 0). However, the default is not recommended due to the
number of messages that will be triggered.
Note
Call Home severity levels are not the same as system message logging severity levels.
Syslog Pattern Matching
When you subscribe a destination profile to the Syslog alert group, you can optionally specify a text
pattern to be matched within each syslog message. If you configure a pattern, a Syslog alert group
message is sent only if it contains the specified pattern and meets the severity threshold. If the pattern
contains spaces, you must enclose it within double quotation marks(“ ”) when configuring it. You can
specify up to five patterns for each destination profile.
