Monitoring and r
eporting methods
System monitor
ing is reported online with a web-based (HTML) user interface and offline by email to
selected conta
cts. Email reporting provides a subset of information provided online.
Hosts and servi
ces are monitored by polling. You schedule polling inter vals for services, but host polling
is purposely kept to a minimum. Depending on the polling interval, there is more or less delay between
occurrences on the system and reporting those occurrences in the PCC interface. In general, a host is
polled only at system startup and after one or more service checks indicate a potential host problem. As
long as services appear to be functioning correctly (OK), the host is assumed to be healthy (UP). You can
selectively
enable or disable hosts and services p olling.
If monitorin
g indicates a host is not functioning correctly (DOWN), none of its services are available
(they can hav
e any status except O K). If a service has CRITICAL status, b ut the host is UP, the service
probably needs to be restarted.
Statuses and states
Various PCC views show current life cycle states of smart cells or status values of particular hosts or
services. Status values m easu re relative health, and can be associated with a status condition c onveying
ameasureofconfidence in the reported value. This section definespossiblelifecyclestates,status
values, and status conditions.
For example, the health of a sma rt cell in the life cycle state DEAD can be reported with the host status
value DOWN. If the host status value has been checked the required number of times, the status condition
is reported as HARD (otherwise, it is SOFT).
PCC views often use “status” and “state” loosely and interchangeably when referring to hosts and
services. State is always used when referring to smart cell life cycle states, but status and state are both
used when reporting smart cell health, regarding it as a host like any other. PCC views also refer to
status conditions as states or state types.
System component status is color coded: green indicates normal operation; red indicates component has
stopped or failed; yellow indicates a warning. See "Host and service status values" on page 29.

Metaserver and smart cell are determining cell's start
