FAQ 15

If you and your friends are LogCenter Cloud users, you can monitor the same server together.

First, click the member at the top right, and the screen appears on the right.

Click Invite New Members and enter your friend's mail account to invite you to your domain.

You can then check out your friend at My Member.

Then go to the Host information on that server and click the Member tab.

Click Add member to add members.

Then go to the Host information on that server and click the Member tab.

Click Add member to add members.

If resource information does not appear in Topology or Trend, it is likely that the SNMP connection is not correct.

At that time, you need to check the following four things.

First, make sure that the server has SNMP installed. If not installed, refer to here

If installed, make sure SNMP service is running.

Once the SNMP package is installed, you must configure the SNMP.
If you do not set up, you may not be able to connect even if the service is running.
here for instructions on configure SNMP.

Second, please check the version of the SNMP protocol used. 

If you set only the community value on the server, you must connect to SNMP V1 or V2

and if you connect to V3, you must set Auth protocol, Auth password, private protocol, and private password.

Therefore, check the SNMP configure file on the server and try to reconnect it

Third, resource information cannot be shown if the configure SNMP V3 set on the server is different from it was entered in the LogCenter Cloud

Check the configuration file on the server and try again.

Finally, if you connect a server in use in the cloud, it may be due to the firewall provided by the cloud.
In this case, the SNMP port must be allowed on the firewall to confirm information about the resource in the LogCenter Cloud.

even after you’ve checked the above If you can’t see the resources of system, you send us use one-on-one inquiries at the bottom of the screen.

after that we will check the problem and support you about that.

Thank you

An Notification occurs when the server's resources exceed the threshold value you set.
The Notification can be seen by click the bell-shaped icon at the top right.

If you click the notification, you can see the detail of alarm in History

If you have finished connecting to SNMP,

 you can check the resource information of the server directly from the topology.
if you click the host icon on the topology, then resource summary information appears

You can check the resource information currently in use

click the information icon on the right side of the host name to see the history of the server and the resource trend chart.

History has a record of you changing the settings, resources exceeding the threshold, or adding members.

Trends help you to monitor servers by providing the resource information of your server as average information per hour.

To use the resource information of the system

SNMP connection must be made between the system and the LogCenter Cloud.

When you click on the host you want to connect to in the topology, the summary information screen for the host pops up.

If the host has SNMP connection, the resource information of the connected system will be displayed, 

otherwise the Go to Connecting button will be displayed. Press the button if you want to connect

Then you will see the [Add Things] on host information screen.
Tap the [Add things] button and appears pop-up.

you should click the SNMP

(Command service is disabled now. We will provide service later.)

then setting screen for SNMP connections appears.

You must enter an IP to connect to Object IP and enter a name to distinguish the server from Object name

Currently, LogCenter Cloud only supports Linux, and OS Type should be set to match the Linux version

Threshold can be adjusted to the number you want, and usually setting between 70 and 90 will help you monitor the server.

Select the SNMP version. You need to enter community values, SNMP NAME, Auth Protocol, Auth Password, Private Protocol, and Private Password according to version.
For V1 and V2, you only need to enter community values, and for V3, you need to enter the protocol and password you set up. 

Click here to learn more about depending on the version.

Finally, you can set up a port and schedule. The SNMP default port uses 162

However, you can also use different ports depending on your settings.

The schedule is the cycle that brings the resource information of the server. 

It is set to 1 minute by default and can be changed between 1 and 10 minutes.

After you have written completed the required items, click the check button next to OS Type to request resource information from the server on the IP you entered.

If the value is right in the pop-up, then SNMP connection is normal, 
and if the value is not visible, you need to check
[I can't see verify the host's resource information. What should I do?] in FAQ.
