What is a Monitoring Tool?

Monitoring tools are software used to collect, store, and analyze system status information. These tools can help us monitor various metrics such as system performance, resource utilization, error rates, etc., retrieve this information in real-time or historically, and adjust the system based on this information.

pgAdmin: Management Tool for PostgreSQL

pgAdmin is an open-source GUI terminal user interface (GUI) tool used to manage distributed relational databases of PostgreSQL. It provides a convenient management interface that can help us monitor and maintain our Postgres database.

1. Install pgAdmin

• You can download the installer from the official website of pgAdmin .
• Or you can use system package managers (such as apt-get, yum, etc.) to install it.

2. Run pgAdmin

• After installation, run commands such as pgAdmin.exe or pgadmin.jar.
• In the interface of pgAdmin, all Postgres databases and other resources can be seen.

3. Monitor PostgreSQL Database

• In the interface of pgAdmin, select the database to monitor, then you can use various reports, tables, etc., functions to view its status information.

Prometheus: An Open-Source Monitoring System

Prometheus is an open-source monitoring system used to collect, store, and analyze system status information. It is a multi-language API that allows us to monitor and manage our services in multiple ways.

1. Install Prometheus

• You can download the installer from the official website of Prometheus .
• Or you can use system package managers (such as apt-get, yum, etc.) to install it.

2. Run Prometheus

• After installation, run commands such as prometheus --config.file=/etc/prometheus/prometheus.yml.
• In the configuration file of Prometheus, various monitoring-related options can be customized.

3. Monitor Services and Applications

• In the interface of Prometheus, you can add services or applications that need to be monitored. Then use tools such as Grafana interfaces to view this information.
• You can write custom monitoring scripts in multiple languages (such as go, python, etc.).

Grafana: An Open-Source Data Visualization Platform

Grafana is an open-source data visualization platform that helps us retrieve and display system status information in real-time or historically.

1. Install Grafana

• You can download the installer from the official website of Grafana .
• Or you can use system package managers (such as apt-get, yum, etc.) to install it.

2. Run Grafana

• After installation, run commands such as grafana-server --config.file=/etc/grafana/grafana.ini.
• In the interface of Grafana, all data visualization dashboards and other resources can be seen.

3. Monitor Services and Applications

• In the interface of Grafana, you can add services or applications that need to be monitored. Then use various data visualization charts to display this information.
• You can write custom data visualization scripts in multiple languages (such as go, python, etc.).

Summary
