Action 1
Points to check
Was the monitoring permission host definition performed correctly on the selected host (monitored server)?
Action method
Define the host name of the monitoring server correctly in the Define Monitoring Permission Host window of the selected host.
Action 2
Points to check
Was the name correctly resolved in the TCP/IP network environment of the selected host?
Action method
Ensure that the TCP/IP network environment of the selected host allows names to be resolved correctly.
Information
Execute the ping command on the monitoring host, and check if the displayed IP address matches the IP address of the monitored host.
Refer to the relevant operating system manual for information on the ping command.
Action 3 [V11.0L10/11.0 or later]
Points to check
Did you try to connect to more clients on the monitoring server after the limit for the number of connected clients was exceeded?
Action method
Increase the limit value for the number of client connections on the monitoring server, or reduce the number of clients connected to the monitoring destination server.
Action 4
Points to check
On the monitored server, does the IP address obtained from the host name specified as the monitoring permission host after the name was resolved match the primary IP address of the monitoring host?
Action method
If the IP addresses do not match, specify the primary IP address of the monitoring host in the monitoring permission host.
Information
In the same way as for Action 2, execute the ping command to check the IP address obtained by resolving the name. Execute the ping command on the monitored host, and check if the displayed IP address matches the primary IP address of the monitoring host.
Refer to the relevant operating system manual for information on the ping command.
Action 5
Points to check
Is "127.0.0.1" configured as the IP address for the name of the local host in /etc/hosts?
Action method
The IP address for the name of the local host specified in /etc/hosts must be an address that can be connected from the client.
An example of /etc/hosts file settings is shown below.
[Before]
127.0.0.1 <host name> localhost |
[After]
127.0.0.1 localhost |
Note: xxx.xxx.xxx.xxx is the IP address for <host name> (localhost).
