I’m Akihiro, work for the Customer Support Division.
In this year, as a Serverworks’ Zabbix specialist, I would like to share my knowledge of Zabbix both in Japanese and English, and hopefully end up with making a presentation at Zabbix Conference held in Latvia.
I got the Zabbix compatible sensor kit introduced by Kodai of Zabbix Japan which is not on sale right now.
“IoT” might remind you as AWS IoT, but today as Zabbix, handling sensor data.
In this article, I introduce the procedure to collect environment data of network equipment using this sensor kit with Zabbix.
Zabbix can collect information on network equipment and server hardware by SNMP and IPMI,
By using it, I will be able to gather inside and outside data and know what is going on to the equipment.
This supports SNMPv1 and Zabbix (active) agent. It uses USB miniB terminal as power supplied and connects a network cable and a sensor cable.
FLS-THP Temperature, humidity, barometric pressure sensor
This sensor collects temperature, humidity and barometric pressure data.
Controller and sensor connect with UTP cable of category 5 (or higher), power supplied.
Since the communication protocol is not TCP / IP, it is not possible to interpose a switch or hub between two.
FLS-T15 Temperature Sensor 1.5m Cable
The tip of this UTP cable is a temperature sensor. You can measure the temperature of the narrow place or near rack-mount server.
Setting of the beginning
Set a static local IP address in [IP Settings], or check [DHCP Enable] in [Network Options] to activate DHCP option.
Zabbix Agent Settings
After connecting the sensor, you will enter the controller management screen in the same way as when setting the IP address.
Registering with Zabbix
I assume that you have already built Zabbix.
For instructions on building Zabbix, please refer to this manual.
Register an agent type as “Zabbix agent (active)”.
The item keys of each sensor are as follows;
|Sensor Type||Item Key||Type of information|
|Atmospheric pressure sensor||press.N||Numeric(float)|
|Contact sensor (A connector ON / OFF status)||in.a.N||Numeric(unsigned)|
|Contact sensor (A connector ON count)||cnt.a.N||Numeric(unsigned)|
|Contact sensor (B connector ON / OFF status)||in.b.N||Numeric(unsigned)|
|Contact sensor (B connector ON count)||cnt.b.N||Numeric(unsigned)|
Confirm Sensor Data
Since this sensor unit is wired connection, it is not suitable for applications where it is arranged in large quantity by wireless connection.
However, when acquiring environmental data near IT equipment such as network rack, it is worth to use.
Next time, I would like to introduce a way to combine with collected data and AWS IoT with grafana.
