Ping polling status tables

The NCMONITOR ping polling status tables enable diagnostic operations to be performed on network ping polling.

expectedIps table
The expectedIps table contains a list of IP addresses expected to be discovered by Network Manager for a particular domain. It is populated using the ncp_upload_expected_ips.pl script.
pollLog table
The pollLog table stores the latest snapshot of the status of the Polling engine. It is populated using the ncp_ping_poller_snapshot.pl script which queries ncp_poller, and transfers the results to this table.
pollLogSummary table
This table stores a summary of the results for each snapshot written to the pollLog table for a domain, generated using the views listed in the following sections. It is populated using the ncp_ping_poller_snapshot.pl script which queries the poller, and transfers the results to this table.
undiscoveredIps view
The undiscoveredIps view lists any IP addresses that were are not discovered by Network Manager and therefore are not listed in the NCIM topology database, but that you expected to discover. The IP addresses listed in this table are those that were loaded into the expectedIps table but are not present in NCIM.
unmonitoredIps view
The unmonitoredIps view uses the latest poller snapshot from the pollLog table to list any IP addresses from the expectedIps table that are not currently being polled because they are not in the scope of any active ping policy.
unmanagedIps view
The unmanagedIps view uses the latest poller snapshot from the pollLog table to list any IP addresses from the expectedIps table that are in the scope of active ping policies, but that are not being monitored because they are unmanaged. This is based on the managed status known to the poller at the time of the snapshot.
unpolledFor15MinutesIps view
The unpolledFor15MinutesIps view uses the latest poller snapshot from the pollLog table to list any IP addresses from the expectedIps table that have not been ping polled at all in the last 15 minutes. This includes any IP addresses that are unmanaged or outside the scope of the configured ping polling policies.
delayedPollPolicies view
The delayedPollPolicies view uses the latest poller snapshot from the pollLog table to list all active ping policies are lagging behind schedule.
discoveredIps view
The discoveredIps view lists all IP addresses in the NCIM topology database, together with details of the associated device.
managementInterfaceIps view
The managementInterfaceIps view lists SNMP management interface IP addresses for all devices for which Network Manager obtained SNMP access. It does not list the IP addresses of chassis for which no SNMP access was obtained.
chassisOnlyIps view
The chassisOnlyIps view lists the IP addresses which can only be monitored with the chassis ping polls, as no interfaces with IP addresses have been discovered on these devices. This is usually the case when Network Manager failed to obtain SNMP access to the device, although it can also depend on the discovery configuration.
unpollableIps view
The unpollableIps view lists the IP addresses that the poller will not attempt to ping poll. These IP addresses can be monitored using SNMP poll policies.
