PulseMonitor

This Rust program serves as a simple monitoring tool for MySQL, PostgreSQL and Redis databases. It retrieves configurations from a config.toml file and performs monitoring tasks accordingly.

Features:

• Monitor MySQL, PostgreSQL and Redis databases
• Sends regular pulses to specified uptime monitors
• Easily configurable via config.toml file

Configuration

Before running Pulse Monitor, make sure to create config.toml file and configure all monitors.

#
# START MySQL
#
[[monitors]]
enabled = true
name = "MySQL"
execute_every = 10

[monitors.heartbeat]
method = "GET"
url = ""

[monitors.mysql]
url = "mysql://username:password@localhost:3306/db_name"

#
# START PostgreSQL
#
[[monitors]]
enabled = true
name = "PostgreSQL"
execute_every = 10

[monitors.heartbeat]
method = "GET"
url = ""

[monitors.postgresql]
url = "postgresql://username:password@localhost:5432/db_name"

#
# START Redis
#
[[monitors]]
enabled = true
name = "Redis"
execute_every = 10

[monitors.heartbeat]
method = "GET"
url = ""

[monitors.redis]
url = "redis://username:password@localhost:6379/db_name"

Daemonizing (using systemd)

Running Pulse Monitor in the background is a simple task, just make sure that it runs without errors before doing this. Place the contents below in a file called pulsemonitor.service in the /etc/systemd/system/ directory.

[Unit]
Description=Pulse Monitor 
After=network.target

[Service]
Type=simple
User=root
ExecStart=pulsemonitor --config ./config.toml
TimeoutStartSec=0
TimeoutStopSec=2
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

Then, run the commands below to reload systemd and start Pulse Monitor.

systemctl enable --now pulsemonitor
