The integrated system operation management product "JP1" is very famous in the field of integrated system monitoring, but I would like you to understand that the Zabbix introduced here is also a product that can perform integrated operation management.
Series List
In other words, system monitoring evaluates whether the system is operating normally and whether services can be provided.
1. Because it is OSS, costs can be kept down
The reason Zabbix is preferred is that it is OSS.
General integrated system operation management products require payment of product costs and maintenance costs, but since Zabbix is an OSS, there is no need for product costs. Only maintenance costs may be required in some cases, but in most cases it is only about 1/10 of the cost of general integrated system operation management products.
In addition, no product cost means no agent cost. With general integrated system operation management products, costs are required for each agent, so naturally the more objects to be monitored, the greater the difference in costs.
In addition, the fact that it consists of only one product is also a great advantage.
Taking JP1 as an example, Network Node Manager i (NNMi) for network monitoring, SNMP System Observer (SSO) for resource monitoring, Base for log monitoring, and Integrated Management 2 (IM) for integrated management console And this product is necessary just to perform the minimum server monitoring. As a result, the system becomes more complicated, and not only the product cost but also the introduction cost will increase.
2. Detailed monitoring settings are possible
Zabbix is characterized by its configuration of settings. Even if you are familiar with other server monitoring products, setting up Zabbix can be confusing at first.
However, once you get used to it, you can make settings that are easy to turn around, so compared to other monitoring products, it is possible to make fine-grained monitoring settings. Zabbix can be monitored without installing an agent on the monitoring target, but the number of items that can be monitored increases when an agent is installed.
The main monitoring items at the time of introduction are as follows. In addition to this, you can create and set your own original monitoring items called user monitoring items.
In particular, the function called template is excellent, and setting of monitoring items , and settings such as actions when thresholds are exceeded can be grouped and saved.
This template can be horizontally deployed not only on one host, but also on multiple hosts. Also, by creating a host group for each role, creating a template for monitoring settings for Web servers, and assigning them, it is possible to significantly reduce the man-hours required for setting.

What is Zabbix? Points for using the "strongest" system monitoring automation tool
Serialization: Vital points of server automation
System "automation" is attracting attention, but in that case, parts such as configuration management tools like "Ansible" and "Infrastructure as Code (IaC)" tend to attract attention. However, considering that the period of system operation is much longer than the period of system development, it can be said that the fields of operation management and server monitoring are also very important. This time, we will focus on server monitoring, which is the unsung hero of the system, and explain in detail the widely used open source software (OSS) "Zabbix".

After working as a sales clerk at a major consumer electronics retailer, he jumped into the IT industry and joined BFT, which has strengths in system infrastructure. He encountered VMware in 2010 and learned the fun of creating a complete picture of an infrastructure system by himself. After that, as a project leader, he was mainly involved in system construction and operation for major manufacturers. In addition to VMware, we are promoting projects that incorporate trend technologies in the introduction of configuration management tools that utilize OSS and in the integrated operation management platform, which is one of our strengths. In recent years, he has also been involved in the promotion of his own media, and is engaged in a wide range of writing activities, not just system construction.

What is Zabbix?
Zabbix is an open source software (OSS) integrated system monitoring software created by Alexei Vladyshev. Monitor and track the status of network monitors, server monitors, and other network hardware. It is currently being developed by Zabbix, a company founded by Vladyshev.The integrated system operation management product "JP1" is very famous in the field of integrated system monitoring, but I would like you to understand that the Zabbix introduced here is also a product that can perform integrated operation management.

Why do I need system monitoring?
Then why is it necessary to monitor systems, including servers, in the first place? For example, server monitoring is checking to see if a server is working properly. As a result of checking, if a failure has occurred, promptly escalate it to the system administrator. There are two main types of server monitoring.In other words, system monitoring evaluates whether the system is operating normally and whether services can be provided.
Importance of system monitoring products
When introducing a system, the monitoring mechanism is introduced as a matter of course.Three Benefits of Using Zabbix
So why is Zabbix used for server monitoring when there are other famous products? There are multiple reasons, but let's take a look at three of the most outstanding benefits.1. Because it is OSS, costs can be kept down
The reason Zabbix is preferred is that it is OSS.
General integrated system operation management products require payment of product costs and maintenance costs, but since Zabbix is an OSS, there is no need for product costs. Only maintenance costs may be required in some cases, but in most cases it is only about 1/10 of the cost of general integrated system operation management products.
In addition, no product cost means no agent cost. With general integrated system operation management products, costs are required for each agent, so naturally the more objects to be monitored, the greater the difference in costs.
In addition, the fact that it consists of only one product is also a great advantage.
Taking JP1 as an example, Network Node Manager i (NNMi) for network monitoring, SNMP System Observer (SSO) for resource monitoring, Base for log monitoring, and Integrated Management 2 (IM) for integrated management console And this product is necessary just to perform the minimum server monitoring. As a result, the system becomes more complicated, and not only the product cost but also the introduction cost will increase.
2. Detailed monitoring settings are possible
Zabbix is characterized by its configuration of settings. Even if you are familiar with other server monitoring products, setting up Zabbix can be confusing at first.
However, once you get used to it, you can make settings that are easy to turn around, so compared to other monitoring products, it is possible to make fine-grained monitoring settings. Zabbix can be monitored without installing an agent on the monitoring target, but the number of items that can be monitored increases when an agent is installed.
The main monitoring items at the time of introduction are as follows. In addition to this, you can create and set your own original monitoring items called user monitoring items.
| Monitoring Items | Details |
| CPU | Load Average< /td> |
| CPU usage (system usage, user usage, idle usage, etc.) | |
| Memory | < td>Memory Usage/Memory Usage/Capacity|
| Swap Usage | |
| Network | Number of NW bytes sent/received |
| Disk | File system usage/usage/capacity |
| Disk I/O | |
| Services | Process monitoring (monitoring the number of running processes) |
| Windows Service monitoring (service status monitoring) | |
| TCP port connection status/response time | |
| Logs | Text Log Monitor (string check) |
| Windows Event Log Monitor (string, severity check, etc.) | |
| Files | File Existence Monitor/File Size Monitor |
| Others | Windows Performance Counters |
| Monitoring command execution results (standard output) | |
| Web monitoring (checking the status code and response time of any URL) | |
| VMware monitoring (hypervisor, virtual machine resource monitoring) |
In particular, the function called template is excellent, and setting of monitoring items , and settings such as actions when thresholds are exceeded can be grouped and saved.
This template can be horizontally deployed not only on one host, but also on multiple hosts. Also, by creating a host group for each role, creating a template for monitoring settings for Web servers, and assigning them, it is possible to significantly reduce the man-hours required for setting.
