Monitoring with Info Settings5

Monitoring is an essential part of any IT infrastructure. It allows you to track the performance of your systems and applications, and to identify and resolve problems before they cause outages. There are a variety of different monitoring tools available, each with its own strengths and weaknesses. One popular monitoring tool is Info, which is an open-source, agentless monitoring system.

Info can be used to monitor a wide range of metrics, including CPU usage, memory usage, disk space, and network traffic. It can also be used to monitor the performance of applications and services. Info is a very flexible tool, and it can be customized to meet the specific needs of your organization.

One of the most important features of Info is its ability to monitor through info settings. This allows you to define custom metrics and thresholds, so that you can track the performance of your systems and applications in a way that is meaningful to you.

Configuring Info Settings

To configure info settings, you will need to edit the info configuration file. The default location of this file is /etc/info.d/. You can open this file using a text editor such as vi or nano.

The info configuration file is divided into sections. The main section is the [info] section, which contains global settings for Info. The other sections are used to define custom metrics and thresholds.

To define a custom metric, you will need to add a new section to the info configuration file. The name of the section will be the name of the metric. For example, to define a custom metric called "cpu_usage", you would add the following section to the info configuration file:```
[cpu_usage]
type = gauge
query = df /home/devel/linux/info-0.6.19/agents/ query-mode exec
```

The type field specifies the type of metric. The query field specifies the command that will be used to collect the metric data. In this example, the query command is "df /home/devel/linux/info-0.6.19/agents/ query-mode exec". This command will execute the Python script "/home/devel/linux/info-0.6.19/agents/" with the "query-mode exec" argument, and it will return the CPU usage in percent.

To define a custom threshold, you will need to add a new subsection to the [info] section. The name of the subsection will be the name of the threshold. For example, to define a custom threshold called "cpu_usage_warning", you would add the following subsection to the [info] section:```
[info]
[cpu_usage_warning]
warning = 80
```

The warning field specifies the threshold value. In this example, the warning threshold is 80%. If the CPU usage exceeds 80%, then Info will generate a warning message.

Using Info Settings

Once you have configured info settings, you can use them to monitor the performance of your systems and applications. To do this, you will need to start the Info agent. The Info agent is a daemon that runs in the background and collects performance data. The Info agent can be started using the following command:```
sudo service info start
```

Once the Info agent is running, you can use the Info web interface to view the performance data. The Info web interface is located at localhost:8181. You can use the Info web interface to view graphs of performance data, and to set up alerts.

Info settings are a powerful tool that can be used to monitor the performance of your systems and applications. By defining custom metrics and thresholds, you can track the performance of your systems and applications in a way that is meaningful to you.
