Systems

We called the imRAD device as "System". If you configure an IP address in a system, the information of the system is automatically saving in a few seconds and this menu shows all the saved systems.

List

Systems

The information of systems is saving in the period of about 10 minutes by the smgr service in each device. The smgr service reports the following information.

  • General system information(i.e. version, serial number, uptime, model, and so on)
  • Disk(storage), Memory(RAM), and CPU Load.
  • The status, version, and information of operating service

If you click the "greater than" icon(>) in front of the IP address on each list, you can display more system information.

Item Description
IP Address It is the IP address of the system. If the system has multiple same version addresses, it displays only one address of them.
Name It is the hostname or system name of the system. You can change it via the CLI.
Serial number It is the serial number of the system.
Update Date It is the last datetime the information is saved. If this time is not updating for the "Idle detection timeout for system activity", we notice the system as "System Idle".
Status It shows the status of disk[1] utilization and services. If each disk utilization exceeds the "Warning threshold for Disk utilization rate", it shows a "Notice" icon. If each disk utilization exceeds the "Critical threshold for Disk utilization rate", it shows a "Critical" icon. In the rest of the cases, it shows a "Normal" icon.

If an enabled service is not running, it shows a "Notice" icon.
If you click the trash icon, It will delete the system information. If the deleted system is still running, the information will be saved again.

Model It is the model name of the system
Version It is the current imRAD package version. If you click the icon(Icon bars.png) beside the version, it displays the details.
Uptime It indicates how long the system has been running.
Description It is the description of the operating system.
DUID-EN it is the Vendor-assigned unique ID based on Enterprise Number(i.e. 55344, Basein Networks, Inc.). It is used to have clients identify a DHCPv6 server and is generating by the DHCPv6 service.
RADIUS TLS certificate It is the TLS certificate using by the RADIUS. If you click the icon(Icon bars.png) beside It, you can view the details.
RAM
Disk(OS)
Disk(Data)[1]		 It is the availability of each resource.
CPU Load It shows the CPU load averages over the last 1, 5, and 15 minutes.
Current Failover Mode It indicates the current mode of System Failover.

If the System Failover is not configured, It shows "Not Configured". If the System Failover is configured, it shows either "active" or "passive". The Datetime beside the mode(i.e. active or passive) is the time of the mode was applied.

Database Replication If the System Failover is not configured, this item does not display. If the System Failover is configured, it show "Not Configured", "Master", or "Slave".

The "Not Configured" means that a system is not configured to replicate database. This case is not a normal condition. Therefore, you need to configure the System Failover again.
The "Master" means that the replication mode of the system is "Master".
The "Slave" indicates the replication mode of the system is "Slave".

The circle icon in from of the replication mode(i.e. "Master" or "Slave") indicates the status of the database replication.
The green color means that the status of the database replication is ok. The yellow color indicates that the database replication is ok but the "Seconds_Behind_Master"[2] is high. A high number can indicate that the replication is delaying. Normally the number will be decreasing in few minutes. The red color is replication error. If you click a icon(Icon bars.png) beside the title(i.e. Database Replication), you can find what errors occur.
If the replication error persists for a long time, you need to configure the System Failover again.


(4) 버전
시스템에 적용되어 있는 imRAD 패키지의 버전 및 적용될 날짜를 나타내며 Icon bars.png 아이콘을 클릭하면 상세 버전을 확인 할 수 있습니다.

(5) RADIUS TLS 인증서
RADIUS TLS 통신(TTLS, PEAP 등)에 사용되는 서버 인증서를 나타내며 Icon bars.png 아이콘을 클릭하면 인증서의 상제 정보를 확인 할 수 있습니다.

(7) 시스템 이중화 모드
해당 시스템의 이중화 모드를 표시하면 Active 또는 Passive로 표시됩니다. 만일 시스템 이중화가 되어 있지 않다면 아무런 내용도 표시되지 않습니다.

(7) 데이터베이스 복제
시스템 이중화 모드가 설정된 경우 해당 시스템의 데이터베이스 복제 상태를 표시합니다. 시스템 이중화는 CLI를 통해 설정할 수 있으며 데이터베이스 복제 상태에 문제가 발생하면 CLI를 통해 재 설정 할 수 있습니다.

(8) 서비스
해당 시스템에서 운영중인 모든 서비스 목록을 표시합니다.
상태

상태 아이콘 설명
Icon service active.png 서비스가 정상적으로 동작중입니다.
Icon service active warning.png 서비스 동작에 이상이 감지된 경우입니다.
Icon service inactive.png 서비스가 중지되어 있습니다.

최근 확인시간 / 가동 시간
최근 확인 시간은 서비스의 상태, 이름, 버전 및 가동시간을 확인 후 저장된 최근 시간을 의미하며 가동 시간은 서비스의 uptime을 의미합니다.


메인 데이터베이스 변수

설정된 주요 MariaDB 변수를 출력합니다.


메인 데이터베이스 이벤트

MariaDB 내부에서 스케줄링된 이벤트의 상태를 표시하면 그 상태는 모두 "활성"으로 표시되어야 합니다.
만일 일부 상태가 "비활성" 또는 "Slave 비활성"인 경우 상태 아이콘을 클릭하면 해당 이벤트를 다시 적용 할 수 있습니다.

Syslog

각 시스템에서 발생 한 주요 syslog는 메인 데이터베이스에 저장되는데 이 메뉴에서 확인 할 수 있습니다.
syslog는 notice level 이상만 저장되면 information과 debug는 SSH 접속 후 확인 할 수 있습니다(로그 확인).
