When the state of an FQDN template node is changed (such as being forced offline by user action), one or more messages similar to the following may appear in the LTM log (/var/log/ltm): notice mcpd[####]: 01070638:5: Pool /Common/poolname member /Common/nodename:## monitor status unchecked. [ ] [ was unknown for #hrs:##mins:##sec ] Although such log messages indicate the current state of the FQDN template pool member, the prior status is indicated as "unknown" and does not accurately indicate the prior state of the FQDN template pool member.
Such messages may confuse users who are attempting to monitor changes in the BIG-IP system by not providing clear information.
This may occur when FQDN nodes and pool members are configured, and When the state of an FQDN template node is changed (such as being forced offline or re-enabled from an offline state by user action).
The state of an FQDN template pool member is generally determined by the state of the referenced FQDN template node. The FQDN template node contains the configuration used to resolve the FQDN name to the corresponding IP addresses. FQDN template pool members are not involved in this process, and generally only reflect the status of the name resolution process centered on the FQDN template node. Examining log messages related to to the associated FQDN template node can inform the interpretation of the FQDN template pool member state. For example, if an FQDN template node is forced offline, messages similar to the following will be logged indicating the FQDN template node state change, which is subsequently reflected in FQDN template pool member state changes: notice mcpd[####]: 01070641:5: Node /Common/nodename address :: session status forced disabled. notice mcpd[####]: 01070638:5: Pool /Common/poolname member /Common/nodename:## monitor status forced down. [ ] [ was unknown for #hr:##min:##sec ] notice mcpd[####]: 01070641:5: Node /Common/nodename address :: session status enabled. notice mcpd[####]: 01070638:5: Pool /Common/poolname member /Common/nodename:## monitor status unchecked. [ ] [ was unknown for #hr:##min:##sec ]
